The function h(0) = -16t2 + vt + 10 gives the height of a platform diver above the water, in feet, t seconds after the diver leaves the platform with an initial velocity, v, in feet per second.
10 feet
On one dive, it takes the diver 1.42 seconds to reach the surface of the water.
• What was the initial velocity, V, in feet per second of the diver?
• After how much time, in seconds, since leaving the platform did the diver reach the same height as the platform?
What was the diver's maximum height, in feet, above the water?

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

answer: the is put the 450
