A stone is launched into the air from a height of 240 feet. The height, h, of the stone, in feet, 1 seconds after launch is given by the formula h = - 168 + 32+ + 240. After how long will the stone hit the ground?

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
