b= t/g+m

**Step-by-step explanation:**

Hope this helps.

y = - 3(x + 1 )² + 2

the equation of a quadratic in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

here vertex = (- 1, 2), hence

y = a(x + 1)² + 2

to find a substitute (1, - 10) into the equation

- 10 = 4a + 2 ⇒ 4a = - 12 ⇒ a = - 3

y = - 3(x + 1)² + 2 ← in vertex form

**Answer:**

The rate of change determines the average speed of the ball when it is dropped from the building.

**Step-by-step explanation:**

d(t) = 16t^2

when t = 2

d(t) = 16 (2)²

d(t) = 64

when t = 5

d(t) = 16 (5)²

d(t) = 400

Average speed/rate of change = distance/time = 64/2 = 32 feet

Average speed/rate of change = distance/time = 400/5 = 80 feet

The rate of change determines the average speed of the ball when it is dropped from the building.
