A diving board is 5 feet above the water level of the pool. A swimmer steps off the board into the water. The function d= -16x +5 gives the distance d of the swimmer's feet above the water level after x seconds. a. When does the swimmer's feet hit the water?

b. When will the swimmer's feet be 4 feet below the water level?

c. The high diving board is 15 feet above the water level of the pool. How could you translate the function d = -16x + 5 to adjust for the height of the high diving board?

plss help.. show all work thank you

step-by-step explanation:

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
