Chris drops an egg with a parachute from the top of a building. The height, h, in feet, of the egg above the ground after t seconds is given by h (t) = 100 - 16t2

After how many seconds does the egg hit the ground?

I

The egg hits the ground after 2.5 seconds.

Step-by-step explanation:

Height of the egg:

The height of the egg after t seconds is given by:

After how many seconds does the egg hit the ground?

This is t for which . So

The egg hits the ground after 2.5 seconds.

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
