Answer:
<em>0.4375secs </em>
Step-by-step explanation:
Given the height of the beach ball in feet expressed as;
y = -16t^2+14t+2 as the height that represents the height of the ball, we can look for the time taken by the ball to reach its maximum height
At the max height, the velocity is zero i.e dt/dt = 0
dy/dt = -32t + 14
0 = -32t + 14
32t = 14
t = 14/32
t = 0.4375secs
<em>Hence it took the ball 0.4375secs to reach its maximum height</em>
Answer:
x = -8
Step-by-step explanation:
x = 2y - 4 --- Equation 1
7x + 5y = -66 --- Equation 2
I will be using the substitution method to solve this.
Substitute x = 2y - 4 into Equation 2:
7x + 5y = -66
7(2y - 4) + 5y = -66
Evaluate.
14y - 28 + 5y = -66
Evaluate like terms.
19y - 28 = -66
Isolate 19y.
19y = -66 + 28
= -38
Find y.
y = -38 ÷ 19
y = -2 --- Equation 3
Substitute y = -2 into Equation 1:
x = 2y - 4
x = 2(-2) - 4
Evaluate.
x = -4 - 4
x = -8
The unit rate in dollars per ounce would be $403.90.
