A parachutist jumps out of a plane. Her height, in metres, above the ground after t seconds is given by S(t) = 1750 − 4.9t^2, 0 ≤ t ≤ 19. Estimate the instantaneous rate of change of the parachutist’s height over the interval at t= 8

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

the answer is y = 11.54
