Answer 1
So we know that all the angles from a triangle add up to 180 degrees

Since they give us the measurements of 2 angles we could use those to find the measurements of the other angles.

To find angle 1 we know that the other angles in the smaller triangle are 60 degrees and 90 degrees therefore we would add them up to being 150

60+90=150
180-150=30=m<1

We would then subtract it from 180 to get the measurement of angle 1 which is 30 degrees

We could do the same to find angle 2
90+30=120
180-120=60=m<2
I Need Help With This Problem
Answer 2
Interior angles in triangles always add up to 180

Angle 1 = 180 - 90 - 60 = 30
(90 because there is a right triangle unlabeled)

If angle 1 is 30 and angle 1 and 2 are a right triangle combined (90°), then:

Angle 2 = 90 - 30 = 60

Have a nice day ^^ (again)

Angle 2 = 180 -

Answers

In the case of regression analysis, the dependent variable must be metric; in multiple discriminant analysis, the dependent variable is nominal in nature. (Option B)

Regression analysis refers to a collection of statistical methods which are used for the estimation of relationships between a dependent variable and one or more independent variables. It can used to assess the strength of the relationship between variables and for modeling their future relationship. In regression analysis the dependent variable is metrically scaled (where distance between values can be calculated). Multiple discriminant analysis is a regression technique used in statistics to group objects into categories for analysis. In multiple discriminant analysis the dependent variable is nominally scaled (where characteristics can be distinguished).

A satellite dish is shaped like a paraboloid of revolution. This means that it can be formed by rotating a parabola around its axis of symmetry. The receiver is to be located at the focus. If the dish is 24 feet across at its opening and 2 feet deep at its center, where should the receiver be placed?
Find the equation of the parabola?
How far above the vertex should the receiver be placed?

Answers

Equation of parabola: y =ax² and receiver should be placed 18 feet above vertex.

Explanation:

Considering satellite dish as parabola we can have vertex as origin and concave upward.

So, equation of parabola will be justifying structure of satellite dish i.e

y = ax² -------(1)

Two points other than (0,0) are (-12,2) and (12,2), unit being feet.

This points will satisfy equation of parabola, substituting them in equation 1, we will calculate the value of constant 'a'.

a = [tex]\frac{2}{12^{2} }[/tex]

[tex]\frac{2}{2*6*12}\\ =\frac{1}{72}[/tex]

Substituting value of a = 1/72 in equation 1 we get

72y = x²

As receiver need to be located at focus, so it will be places at a distance of 'p' above the vertex

4p = 72

Dividing both sides by 4, we get

p = 18 feet

So, receiver will be placed at a distance of 18 feet above vertex.

Compute the scalar surface integral ∬T(z+y)dS where T is the triangle (including its interior) with vertices (0,0,2), (0,1,0)( and (1,0,0)

Answers

the scalar surface integral ∬T(z+y)dS where T is the triangle (including its interior) with vertices (0,0,2), (0,1,0)( and (1,0,0) is 1

We can compute the scalar surface integral ∬T(z+y)dS using the parametric form of the surface integral.

Let S be the surface of the triangle. We can parameterize S as follows:

S(u,v) = (u, v, 2-u-v)

where 0 ≤ u ≤ 1 and 0 ≤ v ≤ 1-u.

Then, the scalar surface integral ∬T(z+y)dS is defined as:

∬T(z+y)dS = ∬S(u,v) (2-u-v + v) dudv

= ∫0→1∫0→1-u (2-u-v + v) dudv

= ∫0→1 [2u + (1-u)2 - (1-u)2u - u2(1-u)] du

The time it takes a freshman to choose their major is thought to have a standard deviation of one year by an undeclared major. A t-distribution table can be used to determine the crucial value.

The confidence interval for the average time it takes for freshmen to pick a major can be found by taking the sample mean of the 10 freshmen surveyed and adding and subtracting

The margin of error is calculated by multiplying the sample standard deviation by the critical value from a t-distribution with degrees of freedom equal to (n-1), where n is the sample size.

Farah wants to have a cool million dollars to retire with when she is 55. How much must she invest today at age 19 into an account that pays 8% compounded monthly to accomplish this goal?

Sam also wants a cool million dollars when he is 55 but is willing to put away money every year. How much must he put away each year after his 21st birthday with same interest rate as Farah but his investment is compounded annually?

Answers

To calculate how much Farah must invest today at age 19 to have a cool million dollars when she is 55, we need to know how many years she has until she retires. Since Farah wants to retire at age 55, she has 55-19 = <<55-19=36>>36 years until she retires.

We also need to know the interest rate that the account pays and the frequency at which the interest is compounded. In this case, the interest rate is 8% and the interest is compounded monthly.

To calculate how much Farah must invest, we can use the formula for the future value of an annuity, which is given by:

FV = PMT * (((1 + i)^n - 1) / i)

where FV is the future value that Farah wants to have, PMT is the amount that Farah must invest each period, i is the interest rate per period, and n is the total number of periods.

Since Farah wants to have a cool million dollars, we can set FV equal to $1,000,000. We also know that the interest rate is 8% and that the interest is compounded monthly, so we can set i equal to 8% / 12 = 0.006667. Finally, we know that Farah has 36 years until she retires, so we can set n equal to 36 * 12 = 432, since there are 12 months in a year.

Substituting these values into the formula above, we get:

FV = PMT * (((1 + i)^n - 1) / i)

FV = PMT * (((1 + 0.006667)^432 - 1) / 0.006667)

To solve for PMT, we can divide both sides of the equation by ((1 + 0.006667)^432 - 1) / 0.006667, which gives us:

PMT = FV / (((1 + i)^n - 1) / i)

PMT = $1,000,000 / (((1 + 0.006667)^432 - 1) / 0.006667)

Calculating this value gives us a result of PMT = $176.72, which is the amount that Farah must invest each month to have a cool million dollars when she is 55.

Now, let's consider Sam's situation. Sam also wants to have a cool million dollars when he is 55, but he is willing to put money into his account every year instead of every month. This means that the frequency at which the interest is compounded will be annual instead of monthly.

To calculate how much money Sam must put into his account each year, we can use the same formula as above but with a few changes. In particular, we need to set i equal to 8% / 1 = 0.08, since the interest is compounded annually, and we need to set n equal to 55-21 = <<55-21=34>>34, since Sam has 34 years until he retires.

Substituting these values into the formula above, we get:

FV = PMT * (((1 + i)^n - 1) / i)

FV = PMT * (((1 + 0.08)^34 - 1) / 0.08)

Solving for PMT gives us:

PMT = FV / (((1 + i)^n - 1) / i)

PMT = $1,000,000 / (((

Write an inequality to solve the problem and then solve showing your work. Explain what the solution to the inequality means.

Answers

Answer:

She will have a balance of more than $18 for up to 6 days

Step-by-step explanation:

Start with $30.

Each day, x, subtract $1.99 from $30.

30 - 1.99x

The amount must be greater than $18.

30 - 1.99x > 18

Subtract 30 from both sides.

-1.99x > -12

Divide both sides by -1.99. Remember than when you multiply or divide both sides of an inequality by a negative number, the inequality sign changes direction.

-1.99x/(-1.99) < -12/(-1.99)

x < 6.03

The number of days must be less than 6.03. Since we deal with whole days, she will have a balance of more than $18 for up to 6 days.

Hello,

I hope you and your family are doing well!

To find the number of students who took Science, Dance, or English, you can add the number of students in each individual category and then subtract the number of students who took all three courses, since those students were counted twice. This gives a total of 1031 + 1058 + 1059 - 218 = 3100 students.

To find the number of students who took Dance and English, but not Science, you can add the number of students in region VII and region VIII, which is 456 + 11 = 467 students.

To find the number of students who took Science or didn't take Dance, you can add the number of students in region I and region III, which is 1031 + 218 = 1249 students.

To find the number of students who took none of the courses, you can add the number of students in region II and region IV, which is 449 + 459 = 908 students.

To find the number of students who took Science or English, but not Dance, you can add the number of students in region V and region VI, which is 1059 + 459 = 1518 students.

(3, 4)  I think it is a solution to the inequality. Because when you graph it (3, 4) looks like it is shaded meaning that it is a solution. (If wrong, I'm sorry)

The inequality that represents the numbers of apples and pears you can buy is 0.40x + 0.65y ≤ 3.50.

What is a solution set to an inequality or an equation?

If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality. Set of such values is called solution set to the considered equation or inequality.

Given;

The cost of the apples = $0.40 per apple

So, the cost of x apples is 0.40x.

The cost of the pears = $0.65 per pear

So, the cost of y pears is 0.65y.

The total cost of the apples and pears is the sum of the cost of the apples and the cost of the pears, which is 0.40x + 0.65y;

Since we can spend at most $3.50 at the market, the total cost of the apples and pears must be less than or equal to $3.50;

Therefore, the inequality that represents the numbers of apples and pears you can buy will be 0.40x + 0.65y ≤ 3.50;

The cubic function is f(x) = x^3 + 8x^2 - 32x + 32, which has a local maximum value of 4 at x = -4 and a local minimum value of 0 at x = 2.

The cubic function f(x) is of the form f(x) = ax^3 + bx^2 + cx + d, where a, b, c, and d are constants. In this case, a = 1, b = 8, c = -32, and d = 32. The local maximum value of 4 occurs when x = -4 and the local minimum value of 0 occurs when x = 2.To find the equation, we must use the given information to solve for the constants. The function must equal 4 when x = -4, so f(-4) = 4. Plugging in the values for the constants we have 4 = -4^3 + 8(-4)^2 - 32(-4) + 32. Solving this equation, we find that d = 32, so the equation becomes f(-4) = -64 + 256 + 128 + 32 = 4. Similarly, we set f(2) = 0, so 0 = 8 + 16 - 64 + 32. Solving this equation, we find that c = -32, so the equation becomes f(2) = 8 + 16 - 32 + 32 = 0. Finally, we have the equation f(x) = x

[tex]5.0625 = \left(\dfrac{b}{2}\right)^2[/tex]

[tex]\sqrt{5.0625} = \dfrac{b}{2}\right[/tex]

[tex]4.5 = b[/tex]

Then, we can substitute that into the term [tex]by[/tex].

[tex]16(y^2 + 4.5y+5.0625)[/tex]

Finally, distribute the 16 and then take the middle term as the answer.

[tex]16y^2 + 72y+81[/tex]

72y

Answer:

72y or -72y

-----------------------------

We are given a binomial and need to add a monomial to make it a perfect square.

Recall the identities for a square of a sum or difference of two numbers:

(a ± b)² = a² ± 2ab + b²

Analyze the given and compare with the identity above:

16y² + ... + 81Here 16y² = (4y)² and 81 = 9², so a = 4y and b = 9.

To complete the square we need to add ± 2ab, which is:

± 2ab = ± 2(4y*9) = ± 72y

By adding this we get:

16y² + 72y + 81 = (4y + 9)²

or

16y² + (-72y) + 81 = (4y - 9)²

Is this correct? Or no?

Answers

Answer:

No

Step-by-step explanation:

No, this is not correct. When you divide both sides of an inequality by a negative number, the inequality symbol must be reversed. So in this case, dividing both sides of the inequality -3x > 9 by -3 would give us x < -3, which is not what Diego claimed.

The slope of the line is 3.

What is slope?

The slope or gradient of a line is a number that describes both the direction and the steepness of the line.

Given that, are points of a line,

The slope of a line passing through two points is = (y₂-y₁)/(x₂-x₁)

Considering the points (0, 3) and (1, 6)

Therefore, slope = (6-3)/(1-0) = 3

Hence, the slope of the line passing through the given points is 3.

Descartes's number is the 46.989, which is less than 47 and higher than 46.98.

Define Descartes's number.

A Descartes number is an odd number with the formula n = m p, where m and p are coprime numbers and 2n = (m) (p + 1). P is regarded as a "spoof" prime in this formula. The only known example is the one that was provided. The invention of Cartesian or analytic geometry, which employs algebra to describe geometry, is one of Descartes's most enduring contributions. In equations, Descartes "introduced the convention of denoting unknowns by x, y, and z, and knowns by a, b, and c." A Descartes number is an odd integer that, if one of its composite elements were prime, would have been an odd perfect number.

Enter your answer as an ordered triple.

Answers

The solution to the system, as an ordered triple is: (3, -4, 6).

How to Solve a System of Equations?

To solve the following given system of equations:

2x + y + 3z = 20 --> eqn. 1

x + 2y - z = -11 --> eqn. 2

3x - 2z = -3 --> eqn. 3

Multiply equation 1 by 2 to get eqn. 4:

4x + 2y + 6z = 40 --> eqn. 4

Subtract eqn. 4 from eqn. 2:

x + 2y - z = -11 --> eqn. 2

4x + 2y + 6z = 40 --> eqn. 4

-3x - 7z = -51 --> eqn. 5

Add equations 3 and 5 together:

3x - 2z = -3 --> eqn. 3

-3x - 7z = -51 --> eqn. 5

-9z = -54

z = -54/-9

z = 6

Substitute the value of z into equation 5:

-3x - 7(6) = -51 --> eqn. 5

-3x - 42 = -51

-3x = -51 + 42

-3x = -9

-3x/-3 = -9/-3

x = 3

Find the value of y by substituting the values of x and z into equation 1:

2(3) + y + 3(6) = 20 --> eqn. 1

6 + y + 18 = 20

24 + y = 20

y = 20 - 24

y = -4

The solution as an ordered triple is: (3, -4, 6).

What is 2 1/5 divided by 4/5 in mixed number form???​

Answers

2/5 is the best time to get your order
So in order for you to do this problem you have to start by turning the 2 1/5 into a mixed number. And you would do that by multiplying the 2 and the 5 which is 10 and adding a 1 which is 11 and put it over the denominator
2x5=10+1=11/5

And for the next part it’s going to form the problem
11/5 / 4/5

We would then want to change the sign since we cannot divide a fraction with another fraction this way so we would do KCF
Which stands for Keep, Change and Flip
We would Keep the first fraction which is 11/5 and change the divide sign to a multiplication sign and Flip our second fraction being 4/5. It would then look something like this:

11/5 x 5/4

Then multiply across and you would get 55/20 as your answer but it would be better to simplify it to being 11/4

Answers

The solution of the given inequality 6 - 4( 6 n+7 )  ≥ 122 is given by

n ≤ -6.

As given in the question,

Given inequality is :

6 - 4( 6 n+7 )  ≥ 122

Open the parenthesis of the given inequality we get,

⇒ 6 - 24n - 28 ≥ 122

⇒ 6 - 28 -24n ≥ 122

⇒ -22 -24n ≥ 122

Add 22 on both the side of inequality we get,

⇒ -22 + 22 -24n ≥ 122 + 22

⇒ -24n ≥ 144

Divide both the side by ( -24 ) we get,

⇒ n ≤ -144/ 24

⇒ n ≤ -6.

This shows that n has all the less than or equal to -6.

Therefore, the solution of the given inequality is equal to n ≤ -6.

How to fill the Venn Diagram?

The Venn diagram starts to be filled from the most restrictive conditions, towards the least restrictive.

2% of people answered all three, hence:

V = 2%.

3% of people answered light rail and bus, hence:

IV + V = 3%

IV = 1%.

6% of people answered light rail and carpool, hence:

II + V = 6%

II = 4%.

2% of people answered carpool and bus, hence:

V + VI = 2%

V = 0%.

11% of people answered carpool, hence:

III + II + V + VI = 11

III + 4 + 2 + 0 = 11

III = 5%.

10% of people answered bus, hence:

IV + V + VI + VII = 10

1 + 2 + 0 + VII = 10

VI = 7%.

16% of people answered light rail, hence:

I + II + IV + V = 16

I + 4 + 2 + 1 = 16

I = 9%.

Then the or percentage is given as follows:

9 + 7 + 5 + 1 + 2 + 4 = 28%.
