The point which is on the y-axis and is the y axis and is 7 units from the point (-7, -5) is;

Since the point is on the y-axis, it follows that it's x-coordinate is zero and hence; the point is; (0, y).

The distance is therefore 7 units and hence;

7² = (-7-0)² + (y - (-5))²

49 -49 = (y +5)²

0 = y +5

y = -5

Answer:

b. Interval estimation

Step-by-step explanation:

There are two types of estimations for each population parameter; the point estimation and confidence interval (CI) estimation.

The point estimation involves the use of sample data to calculate a single value which serve as a best estimate of an unknown population parameter.

The interval estimation is the use of sample data to calculate range of possible values of an unknown population parameter.

Therefore, the correct option is "b"

Step-by-step explanation:

he is putting in by the 3/5

Answer:

C.

Step-by-step explanation:

Why its C...

You can tell that on the top it say that the total is 15 so it can not be a. So now our answer choices are B, C, ad D.

Now it says that there are 3/5 highlighted but since the rest say 3/5 we can not eliminate yet.

Next we would multiply 3 x 3 to get 9 for how many dollars there are. Cross out B.

Between C and D, C is the most reasonable answer because it says how much did he put in the bank while the other one (D) says how much did he spend?

So it would be C

Answer:

110

Step-by-step explanation:

nth term = 3n + 2

3 (36) + 2

108 + 2 = 110

Answer:

The 36th term in the sequence is 104.

Here's how to find it:

- Start with the first number in the sequence: 5.

- Add the common difference, which is 3, to get the second number in the sequence: 8.

- Add the common difference to the second number to get the third number: 11.

- Continue adding the common difference to each subsequent number to find the next term in the sequence.

- The 36th term is three less than 37 times the common difference added to the first term.

- Using that formula, we can calculate the 36th term as: 5 + (36 - 1) * 3 = 5 + 105 = 110.

- Therefore, the 36th term in the sequence is 104.

Answer:

to the nearest whole number, we get:

dd/dt ≈ 490 miles per hour

Step-by-step explanation:

Let's call the distance between the plane and the radar station "d". We want to find the rate at which this distance is increasing when the total distance between the plane and the station is 5 miles.

We can use the Pythagorean theorem to relate the distance d to the altitude h of the plane:

d^2 = h^2 + x^2

where x is the horizontal distance the plane has traveled from directly above the station.

Taking the derivative of both sides with respect to time t, we get:

2d * dd/dt = 2h * dh/dt + 2x * dx/dt

where dd/dt is the rate at which the distance between the plane and the station is changing, and dh/dt and dx/dt are the rates at which the altitude and horizontal distance are changing, respectively.

At the moment when the plane is 5 miles away from the station, we have:

d = 5 miles

h = 1 mile (since the plane is flying at an altitude of 1 mile)

dx/dt = 480 mi/h (since the plane is flying horizontally at a speed of 480 mi/h)

We want to find dd/dt, the rate at which the distance between the plane and the station is increasing. We can solve for dd/dt by plugging in the given values and solving for it:

2d * dd/dt = 2h * dh/dt + 2x * dx/dt

2(5 miles) * dd/dt = 2(1 mile) * 0 + 2x * (480 mi/h)

10 * dd/dt = 960 * x

We still need to find x, the horizontal distance traveled by the plane when it is 5 miles away from the station. We can use the Pythagorean theorem again:

d^2 = h^2 + x^2

(5 miles)^2 = (1 mile)^2 + x^2

x^2 = (5 miles)^2 - (1 mile)^2

x = √(24 miles^2)

x = 4.899 miles (rounded to three decimal places)

Now we can plug in the value of x and solve for dd/dt:

10 * dd/dt = 960 * x

10 * dd/dt = 960 * 4.899

dd/dt = 489.9 (rounded = 490)

The value of constant of variation "k" is

Solution:

Given that the direct variation is:

y = kx ----- eqn 1

Where "k" is the constant of variation

Given that the point is (5, 8)

To find the value of "k" , substitute (x, y) = (5, 8) in eqn 1

Thus the value of constant of variation "k" is k = 8/5 or 1.6

13 triangles can be formed.

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

In triangle ABC, if only one letter is used in each angle.

Then there are only three possible letters to choose from A, B, and C.

Now,

Let's start with the case where all three angles are different.

There are three ways to choose the first angle, two ways to choose the second angle, and one way to choose the third angle.

i.e

3 x 2 x 1 = 6 possible triangles.

Let's consider the case where two of the angles are the same.

There are three ways to choose the repeated angle and two ways to choose the other angle.

i.w

3 x 2 = 6 possible triangles.

When all three angles are the same.

There is only one possible triangle.

Now,

The total number of possible triangles that can be formed if in triangle ABC only a letter in each angle.

Recall that cos(x + y) = cos(x) cos(y) - sin(x) sin(y). So

cos(420°) = cos(360° + 60°)

cos(420°) = cos(360°) cos(60°) - sin(360°) sin(60°)

cos(420°) = cos(60°)

since cos(360°) = 1 and sin(360°) = 0. Then

cos(420°) = cos(60°) = 1/2

Answer: Step-by-step explanation:

To find the average rate of change of a function over an interval, we can use the following formula:

average rate of change = (y2 - y1)/(x2 - x1)

Where x1 and x2 are the values of x at the beginning and end of the interval, and y1 and y2 are the corresponding values of the function at those points.

In this case, we are asked to compare the average rate of change of the functions g(x) and f(x) over the interval where -1≤x≤3.

For the function g(x) = x²+6x, we can plug in the given values for x1, x2, y1, and y2 to find the average rate of change:

average rate of change = (g(3) - g(-1))/(3 - (-1))

= (9 + 18 - (1 - 6))/(4)

= 27/4

= 6.75

For the function f(x) = 2, we can plug in the given values for x1, x2, y1, and y2 to find the average rate of change:

average rate of change = (f(3) - f(-1))/(3 - (-1))

= (2 - 2)/(4)

= 0

Since the average rate of change of the function g(x) is greater than the average rate of change of the function f(x), the function g(x) has a greater average rate of change over the interval where -1≤x≤3.

I hope this helps clarify the comparison of the average rate of change for these two functions. Do you have any other questions?

Among the given options, 90 degrees (option A) is not a solution to the equation sin(2θ) = 1. The equation sin(2θ) = 1 represents the values of θ for which the sine of twice the angle is equal to 1. To determine which option is not a solution, we need to evaluate each choice.

A) 90 degrees: If we substitute θ = 90 degrees into the equation sin(2θ) = 1, we get sin(180 degrees) = 1. However, sin(180 degrees) is actually 0, not 1. Therefore, 90 degrees is not a solution to the equation sin(2θ) = 1.

B) 45 degrees: Substituting θ = 45 degrees gives sin(90 degrees) = 1, which is true. Therefore, 45 degrees is a solution to the equation sin(2θ) = 1.

C) 225 degrees: When we substitute θ = 225 degrees, we get sin(450 degrees) = 1. However, sin(450 degrees) is also 0, not 1. Thus, 225 degrees is not a solution to sin(2θ) = 1.

D) -135 degrees: Similarly, substituting θ = -135 degrees gives sin(-270 degrees) = 1. However, sin(-270 degrees) is 0, not 1. Hence, -135 degrees is not a solution to the equation sin(2θ) = 1.
