Write the equation of the conic section centered at the origin, with a focus at (10, 0) and derictrix at x = 125/10

56

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

210/22 = 9.55

since he can't take part of a person to the game the answer is 9 people

hope this !
