Answer:
c - 12ft
Step-by-step explanation:
-2x + 7y = 10 ⇒ -2x + 7y = 10
x - 3y = -3 ⇒ <u>-2x + 6y = 6 </u>
y = 4
-2x + 7(4) = 10
-2x + 28 = 10
<u> -28 -28</u>
<u>-2x</u> = <u>-18</u>
-2 -2
x = 9
(x, y) = (9, 4)
This is a problem pertaining projectile motion wherein the parameter we're finding is the angle of inclination denoted as theta. The formula to be used is the range:
Range = v^2*sin(2*theta)*(1/g)
100 = (60^2) * sin(2*theta) * (1/32.2)
theta=31.7°
