Find The Measures Of Angle A And B. Round To The Nearest Degree.
Answer 2

Answer:

A ≈ 32°B ≈ 58°

Step-by-step explanation:

You want the measures of angles A and B in right triangle ABC with hypotenuse AB = 15, and side BC = 8.

Trig relations

The mnemonic SOH CAH TOA reminds you of the relationships between side lengths and trig functions in a right triangle:

  Sin = Opposite/Hypotenuse

  Cos = Adjacent/Hypotenuse

Application

Here, the hypotenuse is given as AB=15. The side opposite angle A is given as BC=8, so we have ...

  sin(A) = 8/15   ⇒   A = arcsin(8/15) ≈ 32°

The side adjacent to angle B is given, so we have ...

  cos(B) = 8/15   ⇒   B = arccos(8/15) ≈ 58°

Of course, angles A and B are complementary, so we can find the other after we know one of them.

  B = 90° -A = 90° -32° = 58°

The measures of the angles are A = 32°, B = 58°.

Additional comment

The inverse trig functions can also be called arcsine, arccosine, arctangent, and so on. On a calculator these inverse functions are indicated by a "-1" exponent on the function name—the conventional way an inverse function is indicated when suitable fonts are available.

You will note the calculator is set to DEG mode so the angles are given in degrees.

find r(t) if r'(t) = t^5 i + e^t j + 3te^3t k and r(0) = i + j + k.
r(t) = _____

Answers

Based on the given function the r(t) = (1/6)t^6 i + (e^t - 1) j + (e^3t - 1) k

Given r'(t) = t^5 i + e^t j + 3te^3t k, we can integrate each component separately to obtain r(t).

Integrating the x-component, we get ∫t^5 dt = (1/6)t^6 + C1, where C1 is the constant of integration.

Integrating the y-component, we get ∫e^t dt = e^t + C2, where C2 is the constant of integration.

Integrating the z-component, we get ∫3te^3t dt = (e^3t - 1) + C3, where C3 is the constant of integration.

Putting all the components together, we get r(t) = (1/6)t^6 i + (e^t - 1) j + (e^3t - 1) k + C1 i + C2 j + C3 k.

Now, using the initial condition r(0) = i + j + k, we can substitute t = 0 into the expression for r(t) to solve for the constants C1, C2, and C3.

r(0) = (1/6)(0)^6 i + (e^0 - 1) j + (e^(3*0) - 1) k + C1 i + C2 j + C3 k

r(0) = i + j + k

Comparing the coefficients of i, j, and k on both sides, we get C1 = 0, C2 = 1, and C3 = 1.

Substituting these values back into the expression for r(t), we obtain the final answer:

r(t) = (1/6)t^6 i + (e^t - 1) j + (e^3t - 1) k.

Solve for x to make A||B. A 4x + 14 В 3x + 21 x = [ ? ]

Answers

Answer:

x = 7

Step-by-step explanation:

if A and B were parallel then

4x + 14 and 3x + 21 are alternate angles and are congruent , so

4x + 14 = 3x + 21 ( subtract 3x from both sides )

x + 14 = 21 ( subtract 14 from both sides )

x = 7

suppose there is a 38% chance that a mango tree bears Fruit in a given year. For a randomly selected sample of 8 different years, find the mean, Variance and standard deviatin for the number of years that the mango free does not bear fruit?

Answers

In a sample of 8 years, the mean number of years that the mango tree does not give fruit is 4.96, the variance is 1.87, and the standard deviation is 1.37.

The mean, variance, and standard deviation for the number of years that a mango tree does not bear fruit in a sample of 8 different years, given a 38% chance of bearing fruit in a given year, can be calculated using probability theory and statistical formulas.

To begin, we can find the probability of the mango tree not bearing fruit in a given year, which is 1 - 0.38 = 0.62. Using this probability, we can construct a binomial distribution with n = 8 trials and p = 0.62 probability of success (not bearing fruit). The mean (expected value) of the distribution is given by μ = np = 8 x 0.62 = 4.96.

The variance of the distribution is given by the formula σ^2 = np(1-p), which in this case equals 8 x 0.62 x 0.38 = 1.87. Finally, the standard deviation of the distribution is the square root of the variance, which equals sqrt(1.87) = 1.37.

Therefore, the mean number of years that the mango tree does not bear fruit in a sample of 8 years is 4.96, the variance is 1.87, and the standard deviation is 1.37. This means that we can expect the mango tree to bear fruit approximately 3 times in the sample of 8 years.

Answers

Applying L'Hopital's rule, we get: limx→0 sin 3x / 4x = limx→0 3cos 3x / 4 = 3/4 Therefore, the limit of sin 3x / 4x as x approaches 0 is 3/4.



(a) lim(x→0) (sin(3x) / (4x))

To evaluate this limit, we can use L'Hôpital's Rule, which states that if the limit of the ratio of the derivatives of two functions exists, then the limit of the original functions also exists and is equal to the limit of the ratio of their derivatives.

Step 1: Take the derivative of the numerator and denominator with respect to x:
- Derivative of sin(3x) with respect to x: 3cos(3x)
- Derivative of 4x with respect to x: 4

Step 2: Rewrite the limit using the derivatives:
lim(x→0) (3cos(3x) / 4)

Step 3: Evaluate the limit by plugging in x = 0:
(3cos(3*0) / 4) = (3cos(0) / 4) = (3*1) / 4 = 3/4

So, the given limit is 3/4.

for the region r enclosed by x−y = 0, x−y = 1, x y = 1, and x y = 3, use the transformations u = x − y and v = x y.

Answers

To find the region enclosed by these lines, we can graph them in the u-v plane and shade in the region that satisfies all four inequalities. Alternatively, we can solve the four inequalities algebraically to find the range of u and v values that satisfy them.

How to use transformations u = x - y and v = xy to find the region enclosed ?

To use the transformations u = x - y and v = xy to find the region enclosed by the lines x-y=0, x-y=1, xy=1, and xy=3, we need to express these lines in terms of u and v.

First, let's rewrite the lines x-y=0 and x-y=1 in terms of u and v using the given transformations.

For x-y=0, we have u = x - y = x - (x/y) = x(1 - 1/y) = x(1 - [tex]v ^\((-1/2)[/tex]). This can be rearranged to give:

u = x(1 - [tex]v^\((-1/2)[/tex]) = (x y)( [tex]v^\((1/2)[/tex]) = [tex]v^\\(1/2)[/tex] - 1

For x-y=1, we have u = x - y = x - (x/y) = x(1 - 1/y) - 1 = x(1 - [tex]v^\\(-1/2)[/tex]) - 1. This can be rearranged to give:

u = x(1 - [tex]v^\\(-1/2)[/tex]) - 1 = (x y)([tex]v^\\(1/2)[/tex] - 1) - 1 = [tex]v^\\(1/2)[/tex] - 2

Next, we can rewrite the lines xy=1 and xy=3 in terms of u and v:

For xy=1, we have v = xy = x(−u + x) = x² - ux, which can be rearranged to give:

x² - ux - v = 0

Using the quadratic formula, we obtain:

x = (u ± [tex]\sqrt^(u^2 + 4v)[/tex])/2

Note that we must have u² + 4v ≥ 0 in order for x to be real.

For xy=3, we have v = xy = x(−u + x) = x² - ux, which can be rearranged to give:

x² - ux - v + 3 = 0

Using the quadratic formula, we obtain:

x = (u ± [tex]\sqrt^(u^2 + 4v - 12)[/tex])/2

Note that we must have u² + 4v ≥ 12 in order for x to be real.

Putting all of these pieces together, we can now find the region enclosed by the given lines in the u-v plane:

The line x-y=0 corresponds to u = [tex]v^\((1/2)[/tex] - 1.The line x-y=1 corresponds to u =[tex]v^\((1/2)[/tex] - 2.

The line xy=1 corresponds to two curves in the u-v plane:

x = (u + [tex]\sqrt^(u^2 + 4v)[/tex])/2, with u² + 4v ≥ 0, andx = (u - [tex]\sqrt^(u^2 + 4v)[/tex])/2, with u²+ 4v ≥ 0.

The line xy=3 corresponds to two curves in the u-v plane:

x = (u + [tex]\sqrt^(u^2 + 4v - 12)[/tex])/2, with u² + 4v ≥ 12, andx = (u - [tex]\sqrt^(u^2 + 4v - 12)[/tex])/2, with u² + 4v ≥ 12.

To find the region enclosed by these lines, we can graph them in the u-v plane and shade in the region that satisfies all four inequalities. Alternatively, we can solve the four inequalities algebraically to find the range of u and v values that satisfy them.

Juan said that the reason for #9 is ASA~. Why can't it be ASA~ and what is the correct answer?

Answers

By using the Midpoint Theorem and the SAS postulate, we have proven that DE is parallel to BC and that BC is congruent to DE in the quadrilateral ABCA. (option a)

To prove that DE is parallel to BC, we need to show that the corresponding angles are equal. Since E is the midpoint of AC, we can use the Midpoint Theorem to show that AE is equal to EC. Similarly, since D is the midpoint of BA, we can use the Midpoint Theorem to show that AD is equal to DB.

Now we have two triangles, ADE and BDC, with corresponding sides that are equal. Specifically, we know that AD = DB, DE = DC, and angle A is equal to angle B. Using the Side-Angle-Side (SAS) postulate, we can conclude that the two triangles are congruent. This means that the corresponding angles of the triangles are equal, and therefore, DE is parallel to BC.

To prove that BC is congruent to DE, we need to show that the corresponding sides are equal. Since we have already shown that DE = DC, we just need to show that BC = CD. Using the Midpoint Theorem, we know that E is the midpoint of AC, which means that AE = EC. Adding AD to both sides of the equation, we get:

AE + AD = EC + AD

AD + DE = BC

Since AD = DB and DE = DC, we can substitute those values into the equation to get:

DB + DC = BC

Since D is the midpoint of BA, we know that DB + DC = BC. Therefore, we have shown that BC is congruent to DE.

Hence the correct option is (a).

find the coefficient of x^10 in (1 x x^2 x^3 ...)^n

Answers

The coefficient of x^10 in (1 x x^2 x^3 ...)^n is C(n, 10), or "n choose 10".

The expression (1 x x^2 x^3 ...) represents an infinite geometric series with a common ratio of x. The sum of an infinite geometric series with a common ratio of x and a first term of 1 is given by:

sum = 1 / (1 - x)

To find the coefficient of x^10 in (1 x x^2 x^3 ...)^n, we need to find the coefficient of x^10 in the expansion of (1 / (1 - x))^n. We can use the binomial theorem to expand this expression as follows:

(1 / (1 - x))^n = C(n, 0) + C(n, 1)x + C(n, 2)x^2 + ... + C(n, n)x^n

where C(n, k) is the binomial coefficient "n choose k", which gives the number of ways to choose k items from a set of n items. The coefficient of x^10 in this expansion is given by C(n, 10), since the term x^10 only appears in the (n-10)th term.

Therefore, the coefficient of x^10 is C(n, 10), or "n choose 10".

major league baseball game durations are normally distributed with a mean of 180 minutes and a standard deviation of 25 minutes. what is the probability of a game duration of more than 195 minutes?

Answers

The probability of a game duration of more than 195 minutes is approximately 0.2743 or 27.43%.

What is probability?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen.

We can use the standard normal distribution to answer this question by transforming the given data to a standard normal variable (Z-score).

First, we find the Z-score corresponding to a game duration of 195 minutes:

Z = (195 - 180) / 25 = 0.6

Now, we need to find the probability of a game duration being more than 195 minutes, which is the same as finding the probability of a Z-score greater than 0.6.

Using a standard normal distribution table or calculator, we can find that the probability of a Z-score greater than 0.6 is approximately 0.2743.

Therefore, the probability of a game duration of more than 195 minutes is approximately 0.2743 or 27.43%.

Answers

In this case, (a) and (b) are likely independent events, while (c), (d), and (e) may not be.

In order to determine if events E and F are independent, we need to analyze each situation individually.

(a) E and F are likely independent events because a businesswoman's eye color and her secretary's eye color are not related or influenced by each other.

(b) E and F might be independent events. Owning a car and being listed in the telephone book are generally not related. However, there might be some situations where car owners are more likely to be listed in the telephone book, but this connection is weak.

(c) E and F may not be independent events. There might be some correlation between a man's height and weight, as taller individuals tend to weigh more on average. Therefore, these events could be dependent.

(d) E and F are dependent events. If a woman lives in the United States, she must also live in the Western Hemisphere. These events cannot occur independently.

(e) E and F might not be independent events. Weather patterns can be correlated from one day to another, so if it rains tomorrow, it might increase the likelihood of it raining the day after tomorrow.

To evaluate the given integral ∫∫∫r 7(x*y) da, where the region r is defined by [tex]{(x,y)∣25≤x^2 y^2≤64,x≤0}[/tex], we need to express the integral in polar coordinates.

In polar coordinates, x = rcosθ and y = rsinθ.

Therefore, the integral becomes:

∫θ=π/2θ=0 ∫r=8r=5 7[tex](r^2cosθsinθ)^7 r dr dθ[/tex]

Simplifying the integrand, we get:

[tex]∫θ=π/2θ=0 ∫r=8r=5 7r^15(cosθ)^7(sinθ)^7 dr dθ[/tex]

Using the identity [tex]sin^2θ + cos^2θ = 1[/tex], we can simplify[tex](cosθ)^7(sinθ)^7[/tex] as [tex](sin^2θcos^2θ)^3/2[/tex], which becomes [tex](1/4)(sin2θ)^6[/tex].

Therefore, the integral becomes:

[tex](7/4)∫θ=π/2θ=0 ∫r=8r=5 r^15(sin2θ)^6 dr dθ[/tex]

We can evaluate the integral over r first, which gives:

[tex](1/16)(8^16 − 5^16)[/tex]

Simplifying this further, we get:

[tex](1/16)(2^16)(8^8 − 5^8)[/tex]

Next, we evaluate the integral over θ, which gives:

[tex](7/4)(1/16)(2^16)(8^8 − 5^8)∫π/20(sin2θ)^6 dθ[/tex]

This integral can be evaluated using the substitution u = cos2θ, which gives:

suppose a 5 × 3 matrix has 3 pivot columns. is Col A = R^5 ? Is Nul A = R^2? Explain your results

Answers

A 5 × 3 matrix A has 3 pivot columns. Col A is a subspace of [tex]R^5[/tex] with dimension 3, and Nul A is not equal to [tex]R^2[/tex]; it has a dimension of 0.

Suppose a 5 × 3 matrix A has 3 pivot columns. A pivot column is a column in a matrix that has a leading 1 (pivot position) after performing row reduction. Having 3 pivot columns in matrix A means there are 3 linearly independent columns.
Now, let's consider the two parts of your question:
1. Is Col A = R^5?
Col A represents the column space of matrix A, which is the span of its linearly independent columns. Since A is a 5 × 3 matrix with 3 linearly independent columns, the dimension of Col A (the column space) is 3. Therefore, Col A is a subspace of [tex]R^5[/tex], but not equal to [tex]R^5[/tex].
2. Is Nul A = [tex]R^2[/tex]?
Nul A represents the null space of matrix A, which is the set of all solutions to the homogeneous system Ax = 0. The dimension of the null space called the nullity of A, is equal to the number of columns minus the number of pivot columns. In this case, nullity(A) = 3 (number of columns) - 3 (pivot columns) = 0. This means Nul A has a dimension of 0, not 2, and consists only of the zero vector. So, Nul A ≠ [tex]R^2[/tex].
To summarize, Col A is a subspace of [tex]R^5[/tex] with dimension 3, and Nul A is not equal to [tex]R^2[/tex]; it has a dimension of 0.

consider the following higher-order differential equation. y(4) y ‴ y″ = 0 find all the roots of the auxiliary equation. (enter your answer as a comma-separated list.)

Answers

The auxiliary equation for the given higher-order differential equation is r^4 - r^3 + r^2 = 0. To find the roots, we can factor out an r^2 and get r^2(r^2 - r + 1) = 0. Therefore, the roots of the auxiliary equation are r = 0 and r = (1±i√3)/2.

To solve a higher-order differential equation, we must combine the complementary solution (obtained by guessing a function that satisfies the differential equation) and the specific solution (obtained by guessing a function that satisfies the differential equation). Because the differential equation only contains derivatives up to the fourth order in this example, the general solution will contain four arbitrary constants that can be selected by the starting or boundary conditions.

In summary, the roots of the auxiliary equation for the given higher-order differential equation are 0 and (1±i√3)/2. The generic solution of the differential equation will include four arbitrary constants that can be determined by the initial or boundary conditions presented.

Let g = {(7,1),(4, - 5),(-3,- 6),(1,9)} and h = {(9,- 9),(-6,3)}. Find the function hog. hog= (Use a comma to separate ordered pairs as needed.)

Answers

The ordered pairs that are in the domain and range of hog are (-3, (9,-9)) and (7, (-6,3)).

To find the function hog, we need to perform the composition of functions h and g, written as h(g(x)).

First, we need to apply g to its domain, which is {7, 4, -3, 1}.

g(7) = (1,9)
g(4) = (-5,4)
g(-3) = (-6,-3)
g(1) = (9,1)

Now, we can apply h to the range of g.

h((1,9)) = (-6,3)
h((-5,4)) = undefined (since (-5,4) is not in the domain of h)
h((-6,-3)) = (9,-9)
h((9,1)) = undefined (since (9,1) is not in the domain of h)

Thus, the ordered pairs that are in the domain and range of hog are (-3, (9,-9)) and (7, (-6,3)).

Therefore, hog = {(-3, (9,-9)), (7, (-6,3))}.

evaluate the integral. 1 x − 4 x2 − 5x 6 dx 0

Answers

The value of the given integral is ln(3/4).

To evaluate the integral ∫₀¹ (x - 4)/(x² - 5x + 6) dx, we first factor the denominator as (x - 2)(x - 3). Then we use partial fraction decomposition to write the integrand as :

(x - 4)/[(x - 2)(x - 3)] = A/(x - 2) + B/(x - 3)

for some constants A and B. Multiplying both sides by (x - 2)(x - 3), we get

x - 4 = A(x - 3) + B(x - 2)

Substituting x = 2 and x = 3, we obtain the system of equations :

-1 = A(-1) + B(0)
-1 = A(0) + B(1)

Solving for A and B, we find that A = -1 and B = 1. Therefore,

∫₀¹ (x - 4)/(x² - 5x + 6) dx = ∫₀¹ [-1/(x - 2) + 1/(x - 3)] dx
= [-ln|x - 2| + ln|x - 3|] from 0 to 1
= ln(1/2) - ln(2/3)
= ln(3/4).

 (6)    (12)    (2)   (8)

a) To find how many people like at least one drink, we need to add up the number of people in each region of the Venn-diagram:

Milk: 20

Tea: 30

Coffee: 22

Milk and Coffee only: 6

Coffee and Tea only: 2

Milk and Tea only: 8

Milk, Coffee, and Tea: 12

Adding these up, we get:

20 + 30 + 22 + 6 + 2 + 8 + 12 = 100

So 100 people like at least one drink.

b) To find how many people like exactly one drink, we need to add up the number of people in the regions that are not shared by any other drink:

Milk only: (20 - 6 - 8) = 6

Tea only: (30 - 2 - 8) = 20

Coffee only: (22 - 12 - 2) = 8

Adding these up, we get:

find the de whose general solution is y=c1e^2t c2e^-3t

Answers

The general solution includes both terms with c1 and c2, we cannot eliminate c1 and c2 completely. However, we have found the DE relating the second derivative and the first derivative of the given function: d²y/dt² - 2 * dy/dt = 15 * c2 * e^(-3t)Finding the differential equation (DE) whose general solution is given by y = c1 * e^(2t) + c2 * e^(-3t).

To find the DE, we will differentiate the general solution with respect to time 't' and then eliminate the constants c1 and c2.

First, find the first derivative, dy/dt:
dy/dt = 2 * c1 * e^(2t) - 3 * c2 * e^(-3t)

Next, find the second derivative, d²y/dt²:
d²y/dt² = 4 * c1 * e^(2t) + 9 * c2 * e^(-3t)

Now, we will eliminate c1 and c2. Multiply the first derivative by 2 and subtract it from the second derivative:
d²y/dt² - 2 * dy/dt = (4 * c1 * e^(2t) + 9 * c2 * e^(-3t)) - (4 * c1 * e^(2t) - 6 * c2 * e^(-3t))

Simplify the equation:
d²y/dt² - 2 * dy/dt = 15 * c2 * e^(-3t)

Since the general solution includes both terms with c1 and c2, we cannot eliminate c1 and c2 completely. However, we have found the DE relating the second derivative and the first derivative of the given function:

d²y/dt² - 2 * dy/dt = 15 * c2 * e^(-3t)

find an equation of the tangent line to the curve y=8^x at the point (2,64) ( 2 , 64 ) .

Answers

The equation of the tangent line to the curve is y = 16ln(8)x + 32 - 64ln(8).

How to find the equation of the tangent line to the curve?

To find the equation of the tangent line to the curve [tex]y=8^x[/tex]at the point (2,64), we need to find the slope of the tangent line at that point.

The derivative of[tex]y=8^x[/tex] is [tex]y'=ln(8)8^x[/tex]. So at x=2,[tex]y'=ln(8)8^2=16ln(8)[/tex].

Therefore, the slope of the tangent line at (2,64) is 16ln(8).

Now we can use the point-slope form of a line to find the equation of the tangent line. The point-slope form is y-y1=m(x-x1), where (x1,y1) is the point on the line and m is the slope of the line.

Using the point (2,64) and the slope we just found, we get:

y-64 = 16ln(8)(x-2)

Simplifying, we get:

y = 16ln(8)x + 32 - 64ln(8)

So the equation of the tangent line to the curve [tex]y=8^x[/tex] at the point (2,64) is y = 16ln(8)x + 32 - 64ln(8).

0.5 miles = 2,640 feet
O A. True
OB. False

Answers

Answer:

true

Step-by-step explanation:

Yes, the statement "0.5 miles = 2,640 feet" is true.
One mile is equal to 5,280 feet, so half a mile (0.5 miles) is equal to 2,640 feet.

Or

1 mile = 5280

1/2 = 0.5 / 5280 = 5280 / 2 =2640

Determine whether the sequence converges or diverges. If it converges, find the limit. an = (7n+2)/(8n)

Answers

The sequence converges, and its limit is 7/8.

To determine whether the sequence converges or diverges, we can use the limit comparison test. We will compare the given sequence to a known sequence whose convergence behavior is known.

Let bn = 1/n. Then, we have lim (an/bn) = lim ((7n+2)/(8n) * n/1) = 7/8. Since 0 < 7/8 < infinity, and the series of bn converges (by the p-series test), we can conclude that the series of an converges as well.

To find the limit, we can use direct substitution: lim (7n+2)/(8n) = 7/8. Therefore, the sequence converges to 7/8.
