Answer:
Step-by-step explanation:
Okay so you are gonna substitute x for 5 so the equations will look like y= (5)2+(5)2
So 10+10 = 20
So y=20
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.
Answer: 4.089; 4.870; 4.881; 4.89
2 + 65 + 7 × 3
= 2 + 65 + 21
= 67 + 21
= 88
answer is 88
