(a) The vertical motion equation for the ball is h = 8 + 48t - 16t².
(b) The time for the ball to hit the ground is 3.15 s.
(c) The time for the ball to travel 56 ft above the ground is 0.79 s.
<h3>Vertical motion equation for the ball</h3>
The vertical motion equation for the ball is calculated as follows;
h = h₀ + vt - ¹/₂gt²
h = 8 + 48t - ¹/₂(32)t²
h = 8 + 48t - 16t²
<h3>Time for the ball to hit the ground</h3>
0 = 8 + 48t - 16t²
solve the above quadratic equation with formula method;
a = -16, b = 48, c = 8
t = 3.15 s
<h3>Time for the ball to be 56 ft above the ground</h3>
- let upward motion be positive
h = 8 + 48t + 16t²
56 = 8 + 48t + 16t²
0 = -48 + 48t + 16t²
solve the above quadratic equation with formula method;
a = 16, b = 48, c = -48
t = 0.79 s

Answer: The answer is x = +/- 
.
Step-by-step explanation: You can solve this by simply rearranging the equation to make x by itself.
-
= -y - 1
Then cancel out the -1 by dividing it through to obtain.
The final step is to square root both sides to get rid of the exponent.
x =
This should be the answer since square roots have a +/-.
Answer:
$2.30
Step-by-step explanation:
Price- $15.18
Ounces- 6.6
$15.18 ÷ 6.6
=$2.30
The point-slope form is:
y-y1=m(x-x1) so:
y-5=(3/2)(x-3)
