Abullet is shot straight upward with an initial speed of 925 ft/s. the height of the bullet after t seconds is modeled by the function h(t) = −16t2 + 925t where h is measured in feet. use the function h to find the average speed of the bullet during the given time intervals

step-by-step explanation:

need points to ask question

step-by-step explanation:

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
