The graph on the coordinate plane below models the height of a ball after it is thrown up in the air from a platform. The equation ℎ(𝑡) = −16𝑡 2 + 64𝑡 + 80 approximates the height of the ball, in feet, after 𝑡 seconds. Which statements are true? Choose all that are correct.

The average rate of change in the velocity between 𝑡 = 0 seconds and 𝑡 = 2 seconds is 32 feet per second.

. The average rate of change in the velocity, in feet per second between 𝑡 = 0 seconds and 𝑡 = 1 second is greater than the average rate of change in the velocity between 𝑡 = 1 and 𝑡 = 2.

The average rate of change in the velocity, in feet per second, is at a minimum when 𝑡 = 2 seconds.

The average rate of change in the velocity between 𝑡 = 2 seconds and 𝑡 = 3 seconds is 32 feet per second.

The average rate of change in the velocity, in feet per second between 𝑡 = 0 seconds and 𝑡 = 1 seconds is the same as the average rate of change in the velocity between 𝑡 = 0 and 𝑡 = 3.

The profit earned in dollars by a computer manufacturing company when increasing the selling price per computer by 𝑥 dollars is modeled by the function $$p\left(x\right)=-5x^2+1000x+5000$$ . Calculate the average rate of change of profit between a $20 increase and a $50 increase. What does this rate of change mean in terms of the profit made by the company?

650; for each dollar increase in the selling price of the computer, between a $20 and a $50 increase, the company averages $650 more profit.
