Answer:

-409

Step-by-step explanation:

At the beginning - 12,135 subsribers,

Initial number of subsribers = 12,135

At the end - 10,090 subsribers

Final number of subsribers = 10,090

Time = 5 years.

So, the average yearly rate of change is

\dfrac{\text{Final number of subsribers}-\text{Initial number of subsribers}}{\text{Time}}\\ \\=\dfrac{10,090-12,135}{5}\\ \\=\dfrac{-2,045}{5}\\ \\=-409

The number of subscribers decreases by 409 per year

A regular polygon has an exterior angle of 8. what is the sum of all the interior angles
Bogdan [553]

Answer:

7740 degrees.

Step-by-step explanation:

The sum of the exterior angles of all polygons add up to 360 degrees.

So the number of sides and the number of interior angles  in this polygon = 360 / 8 = 45.

Each internal angle = 180 - 8 = 172 degrees, so the sum of all interior angles

= 172 * 45

= 7740 degrees,

marin [14]

Answer:

Option B

Step-by-step explanation:

Taking the derivative of the residual function, then applying the normal equation:

[a; b] = (X'*X)^(X'*y)

with

X = [1 1; 2 1; 3 1; 4 1; 5 1]

X' is transpose of X

y = [11; 8; 4; 1; 0]

[a; b] =  [-2.9 13.5]

State A and state B are among the states with the most remaining drive in movie screens. State A has 4 more screens than state B
mojhsa [17]
State A has 25 drive-in movie screens and State B has 21. You find this by guess-and-checking different numbers that you could add together to get 46. You want to do numbers that are relatively close, as a difference in 4 is not much at all. You can divide 46 by 2 and then play around from there.
