Arock is thrown from the top of a building which measures 48 foot high. the graph shows the height, y, of the rock from the ground after x seconds. on which interval is the rock's height always decreasing

Step-by-step explanation:

The rock's height is increasing in the interval from 0 seconds to 3 seconds.

At time 0 the rock starts moving upward from 52 foot until it reaches 180 foot height (time 3 seconds). Then the rock starts to descend, which means that the height starts to decrease.

2.5 < x < 5.5

Step-by-step explanation:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3
