If the given angle is in standard position, find two positive coterminal angles and two negatives coterminal angles.

a. 110° positive angles:
negative angles:

b. 165° positive angles:
negative angles:

c. -10° positive angles:
negative angles:

Answers

Answer:

a. 110°

Positive coterminal angles: 110° + 360° = 470°, 110° + 2(360°) = 830°

Negative coterminal angles: 110° - 360° = -250°, 110° - 2(360°) = -610°

b. 165°

Positive coterminal angles: 165° + 360° = 525°, 165° + 2(360°) = 885°

Negative coterminal angles: 165° - 360° = -195°, 165° - 2(360°) = -555°

c. -10°

Positive coterminal angles: -10° + 360° = 350°, -10° + 2(360°) = 710°

Negative coterminal angles: -10° - 360° = -370°, -10° - 2(360°) = -730°

Step-by-step explanation:

When an angle is in the standard position, it means that the initial side of the angle is the positive x-axis, and the terminal side of the angle is located in one of the four quadrants of the coordinate plane.

To find coterminal angles, we need to add or subtract multiples of 360 degrees to the given angle while keeping the terminal side in the same position. This is because a full rotation around the origin in the coordinate plane is 360 degrees.

For positive coterminal angles, we add multiples of 360 degrees to the given angle. In the case of 110 degrees, we can add 360 degrees once or twice to get 470 degrees or 830 degrees, respectively.

For negative coterminal angles, we subtract multiples of 360 degrees from the given angle. In the case of -10 degrees, we can subtract 360 degrees once or twice to get -370 degrees or -730 degrees, respectively.

It's important to note that there are infinitely many coterminal angles for any given angle, but we usually restrict our answers to the smallest positive and negative angles that differ from the given angle by a multiple of 360 degrees.

in buying ground beef for hamburgers, there are several packages from which to choose, as shown in the table below. If johannes needs 5 pounds of beef for his barbeque, what will he pay?

Answers

Johannes will need to pay $8.61 for 5 pounds of ground beef

What is the cost of the beef?

Since Johannes needs 5 pounds of ground beef, and the available pounds are 1.5, 2, 3, and 3.75 pounds.

To reduce the cost, he need to select the package with the lowest cost per pound.

The cost per pound for each package is:

Package 1: $5.58 / 1.5

              = $3.72 per pound

Package 2: $7.44 / 2

              = $3.72 per pound

Package 3: $1.16 / 3

              = $0.39 per pound

Package 4: $13.95 / 3.75

                = $3.72 per pound

Therefore, the package with the lowest cost per pound is Package 3 and package 2  which will give us 5 pounds

So he can do it as:

$1.16 + $7.44

= $8.6

Or

(1 package of 3 pounds x $0.39 per pound) + (1 package of 2 pounds x $3.72 per pound)

= $1.17 + $7.44

= $8.61

Therefore, Johannes will need to pay $8.61 for 5 pounds of ground beef.

 The third player hit 4 more home runs than the first player. The algebraic expression that shows the relationship between a and b is:  a = 3b. So option A is correct

What is a linear equation and examples?  

A linear equation in one variable is an equation that has only one variable. It is of the form Ax B = 0, where A and B are  two real numbers and x is an unknown variable with only one solution. For example, 9x + 78 = 18 is a linear equation in one variable.

 2) Each player's home runs are labeled A, B, C, and D, where A is the first baseman, B is the second baseman, C is the third baseman, and D is the shortstop. We know this:

C = 2B (the third player hit twice as many home runs as the second player)

C/B = D/B = A/C (numbers for first baseman and shortstop are proportional to numbers for third baseman and second baseman)

B = D 4 (second baseman hit 4 more home runs than  shortstop)

To solve for the values ​​of A, B, C, and D, we can use the second equation to write:

C/B = D/B

C = D (multiply both sides by B)

C = B - 4 (using the fourth equation to substitute  D)

2B = B - 4 (using the first equation to substitute  C)

B = 4 (interface to both sides 4)

C = 8 (using the first equation to find C)

D = 4 (using the fourth equation to find D)

A = C/2 = 4 (use another equation to find A)

Therefore the third player (C) hit 8 home runs and the first player (A) hit 4 home runs, so the third player hit 4 more home runs than the first player.

3) The relative relationship between a and b can be expressed as follows:

a/b = 6/2 = 3/1

To write this relationship as an algebraic equation, we can cross multiply to get:

a = 3b

Therefore, the algebraic expression that shows the relationship between a and b is:

a = 3b. So option A is correct

Type the correct answer in each box. Use numerals instead of words.
Consider this system of linear equations.
4x - 3y = -8
3x + 2y = -6

The solution to this system is ( , )

Answers

The solution to this system is (-2, 1):

To solve the system of linear equations, we can use the method of substitution or elimination. Here, we will use the method of substitution.

From the second equation, we can solve for y in terms of x:

3x + 2y = -6
2y = -3x - 6
y = (-3/2)x - 3

Now we can substitute this expression for y into the first equation:

4x - 3y = -8
4x - 3((-3/2)x - 3) = -8

Simplifying and solving for x, we get:

4x + (9/2)x = 1
(17/2)x = 1
x = -2/17

Now we can substitute this value of x into the expression we found for y:

y = (-3/2)x - 3
y = (-3/2)(-2/17) - 3
y = 1/17 - 3
y = -50/17

Therefore, the solution to the system is (-2, 1).

find the mass of the lamina that is a portion of the cone z=sqrt(x^2+y^2) that lies between the planes z=1 and z=3 if the density function is fi(x,y,z)=x^2z

Answers

Answer: 6 units

Step-by-step explanation: To find the mass of the lamina, we need to integrate the density function fi(x,y,z) over the volume of the lamina. The lamina is a portion of the cone z=sqrt(x^2+y^2) between the planes z=1 and z=3. We can express this volume using cylindrical coordinates, where rho is the distance from the origin to the point (x,y,z), phi is the angle between the positive x-axis and the line connecting the origin to the point (x,y,z), and z is the height of the point (x,y,z) above the xy-plane.

We have:

1 <= z <= 3

0 <= rho <= 3sin(phi)

0 <= phi <= 2pi

The density function is given by fi(x,y,z) = x^2z. In cylindrical coordinates, we have x = rhocos(phi), y = rhosin(phi), and z = z. Therefore, we can express the density function as:

fi(rho, phi, z) = (rhocos(phi))^2 * z = rho^2cos^2(phi) * z

The mass of the lamina is given by the triple integral of the density function over the volume of the lamina:

M = ∭ fi(rho, phi, z) dV

= ∫∫∫ rho^2cos^2(phi) * z dz dA

= ∫∫[1,3] ∫[0,2pi] ∫[0,3sin(phi)] rho^2cos^2(phi) * z dz d(phi) drho

= ∫[0,2pi] ∫[0,3] ∫[0,rhosin(phi)] rho^2cos^2(phi) * z dz drho d(phi)

= ∫[0,2pi] ∫[0,3] (1/3)rho^3sin(phi)cos^2(phi) d(phi) drho

= ∫[0,2pi] (1/3)[9sin(phi)cos^2(phi)] d(phi)

= (1/3)[9(2/3)]

= 6

Therefore, the mass of the lamina is 6 units.

A chemical solution contains 5.8 ml of water. A chemist adds more water t the solution at a rate of 0.07 ml/s. 9.900 XP 1 How many seconds will it take for the solution to contain 10 ml of water? If your answer is a decimal, give it to 2 d.p.​

Answers

Answer:

60 seconds

Step-by-step explanation:

Let's start by finding how much more water needs to be added to the solution to reach a total of 10 ml of water:

10 ml - 5.8 ml = 4.2 ml

Now we can use the formula:

time = amount of water added / rate of addition

to calculate the time it will take to add 4.2 ml of water at a rate of 0.07 ml/s:

time = 4.2 ml / 0.07 ml/s

time = 60 seconds (rounded to the nearest second)

Therefore, it will take 60 seconds to add enough water to the solution to make a total of 10 ml of water.

Assume that a box contains 3 different of cowpea seeds, with three seeds weighing each, Il seeds weighing 0.81g each, 7 seeds weighing 12g each. What is the probability that a seed selected at random will weigh 0.8​

Answers

The problem states that there are 3 different types of cowpea seeds in the box, but it does not provide any information about the weight of each type of seed. Instead, the problem provides the weight of each individual seed for two of the three types. Therefore, we cannot accurately calculate the probability of selecting a seed that weighs exactly 0.8g from the box using the information provided.

If we assume that the problem meant to say that there are three seeds of each type, and that the weight of the third type is also 0.81g per seed, then we can calculate the probability of selecting a seed that weighs exactly 0.8g as follows:

Total weight of all seeds in the box = (3 x 0.81g) + (3 x 12g) + (3 x 0.8g) = 3.15g + 36g + 2.4g = 41.55g

Probability of selecting a seed that weighs exactly 0.8g = (3 x 0.8g) / 41.55g = 0.0727 or approximately 7.27%

However, since the problem does not provide clear and complete information, it is best to clarify the details or assume that something is missing before attempting to solve it.

what is the answer?

Answers

The inequality |x + 7| ≥ 2 has the solution set x ≤ –9 or x ≥ –5, as required.

Writing an absolute value inequality

We can write an absolute value inequality with the given solution set as follows:

|x + 7| ≥ 2

Here's how we arrived at this inequality:

First, we find the midpoint of the given solution set:

midpoint = (-9 + (-5)) / 2 = -7

Next, we find the distance from the midpoint to each endpoint of the solution set:

distance to -9 = |-7 - (-9)| = 2

distance to -5 = |-7 - (-5)| = 2

The maximum distance is 2, so we use c = 2 in the inequality.

Since the midpoint is to the left of both endpoints, we use the form |x - b| ≥ c.

Plugging in b = -7 and c = 2, we get:

|x + 7| ≥ 2

This inequality has the solution set x ≤ –9 or x ≥ –5, as required.

The formula for the nth term of the arithmetic sequence is an = 4n + 2

How to write a formula for the general term​ (the nth​ term) of the arithmetic sequence?

Let d be the common difference of the arithmetic sequence, and let a1 be the first term. Then we have:

a4 = a1 + 3d = 10

a6 = a1 + 5d = 18

We can solve this system of equations to find a1 and d. Subtracting the first equation from the second, we get:

2d = 8

d = 4

Substituting this into either of the original equations, we get:

a1 + 12 = 18

a1 = 6.

So the arithmetic sequence is:

6, 10, 14, 18, ...

To find the nth term of this sequence, we can use the formula:

an = a1 + (n - 1)d

Substituting in the values of a1 and d, we get:

an = 6 + 4(n - 1)

Simplifying, we get:

an = 4n + 2

Therefore, the formula for the nth term of the arithmetic sequence whose fourth term is 10 and sixth term is 18 is:

an = 4n + 2

(1.3.1) – Plotting Points On A Coordinate Plane

The coordinate plane was developed centuries ago and refined by the French mathematician René Descartes. In his honor, the system is sometimes called the Cartesian coordinate system. The coordinate plane can be used to plot points and graph lines. This system allows us to describe algebraic relationships in a visual sense, and also helps us create and interpret algebraic concepts.

You have likely used a coordinate plane before. The coordinate plane consists of a horizontal axis and a vertical axis, number lines that intersect at right angles. (They are perpendicular to each other.)

A graph with an x-axis running horizontally and a y-axis running vertically. The location where these axes cross is labeled the origin, and is the point zero, zero. The axes also divide the graph into four equal quadrants. The top right area is quadrant one. The top left area is quadrant two. The bottom left area is quadrant three. The bottom right area is quadrant four.
The horizontal axis in the coordinate plane is called the x-axis. The vertical axis is called the y-axis. The point at which the two axes intersect is called the origin. The origin is at 0 on the x-axis and 0 on the y-axis.

Locations on the coordinate plane are described as ordered pairs. An ordered pair tells you the location of a point by relating the point’s location along the x-axis (the first value of the ordered pair) and along the y-axis (the second value of the ordered pair).

In an ordered pair, such as (x, y), the first value is called the x-coordinate and the second value is the y-coordinate. Note that the x-coordinate is listed before the y-coordinate. Since the origin has an x-coordinate of 0 and a y-coordinate of 0, its ordered pair is written (0, 0).

Find the error. A student was finding the measure angle 5 in the figure below. She concluded that m angle 5=86

Answers

The answer is Option 2: The measure of angle 5 is corresponding to angle 1. Angle 1 is supplementary to 86. So, measure angle 1 = 94. Since corresponding angles are equal angle 5 = 94.

What is a supplementary angle?

An angle that, when combined with another angle, creates a straight angle (measuring 180 degrees), is known as a supplementary angle. In other words, if the sum of the measurements of two angles is 180 degrees, they are supplementary. Contrarily, a complimentary angle is one that, when combined with another angle, creates a right angle (which has a 90-degree angle). In other words, if the sum of the measurements of two angles is 90 degrees, they are complimentary. A straight angle and a right angle are not the same thing, hence it is crucial to understand that one angle cannot be both supplementary and complimentary at the same time.

From the given figure we see that the measure of angle 5 is corresponding to angle 1. Angle 1 is supplementary to 86. So, measure angle 1 = 94. Since corresponding angles are equal angle 5 = 94.

Hence, option 2 is correct.

The complete question is:

C(n, k-1) + nC(n, k) = C(n + 1, k)​

Answers

The equation C(n, k-1) + nC(n, k) = C(n + 1, k) is known as the Pascal's rule or Pascal's identity, which relates the binomial coefficients C(n, k) and C(n + 1, k).

To understand how the equation works, we can break down each term:

- C(n, k-1) represents the number of ways to choose k-1 objects from a set of n objects.
- nC(n, k) represents the number of ways to choose k objects from a set of n objects, multiplied by the number of ways to choose one additional object from the remaining n-k objects.
- C(n + 1, k) represents the number of ways to choose k objects from a set of n+1 objects.

By combining these terms, we can see that the left-hand side of the equation represents the total number of ways to choose k objects from n+1 objects. This is equivalent to the right-hand side of the equation, which also represents the number of ways to choose k objects from n+1 objects.

Therefore, Pascal's identity can be used to simplify calculations involving binomial coefficients, making it a powerful tool in combinatorics and probability theory.

What is Exponentiation?

A number's power or exponent, in other words, tells how many times it must be multiplied by itself.

Any integer, fraction, or decimal can serve as the basis in this situation.

Additionally, the exponent might have either a positive or negative value.

Subtract the exponents to divide exponents (or powers) with the same base.

Given that division is the inverse operation of multiplication, it stands to reason that, just as exponents are added when multiplying numbers with the same base, exponents are subtracted when dividing numbers with the same base.

So, we have the exponents as;
9⁻³/9¹²

Then, solve as follows:

9⁻³/9¹²

9⁻³⁻¹²

9⁻¹⁵

Therefore, the given exponents 9⁻³/9¹² in the form 9ⁿ is 9⁻¹⁵ respectively.
