I would say C. and A. Hope this helps.
21/4 ÷ 14/9
21/4 × 9/14
189/56
3/3/8
A.) y = ut - 1/2gt^2 + 12
y = 6t - 1/2(9.8)t^2 + 12
y = 6t - 4.9t^2 + 12
b.) The y-intercept is 12
c.) The y-intercept represent the height of the ball at time t = 0
d.) At the time the ball reaches the ground, y = 0
-4.9t^2 + 6t + 12 = 0
t = 2.29 seconds
Therefore, it took the ball 2.29 seconds to reach the ground.
its all about the angles just subtract the number you have from the total
Step-by-step explanation:
6.3%
that is the correct answer
