An arrow is shot vertically upward at a rate of 250 ft/s. Use the projectile formula h=-16t2 + bot to determine at what times in seconds the arrow is at a height f 500ft

853.3

step-by-step explanation:

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36

use photo math thats what i use u can scan the problem and it tells u the answer
