borishaifa [10]

This exercise should show you that as h approaches zero you get the value of the derivative of x^2 at x=1.

the change in x^2) / h
h=1___
h=.1____
h=0.1_____
h=.001___

change in x^2 = (1+h)^2 - 1^2 = (1+h)^2 - 1

1. A penny is dropped from the top of the empire state building. The function h(t) = -16t^2 +1250 describes the height of the pe

liubo4ka [24]

Answer: $8.83\ s$

Step-by-step explanation:

Given

Height of the dropped penny is given by

$h(t)=-16t^2+1250$

When penny hit the ground, $h(t)=0$

$\therefore -16t^2+1250=0\\\Rightarrow 16t^2=1250\\\\\Rightarrow t^2=\dfrac{1250}{16}\\\\\Rightarrow t=\sqrt{\dfrac{1250}{16}}\\\\\Rightarrow t=8.83\ s$

Thus, it takes 8.83 s to hit the ground.
