A ball is at it maximum height when its velocity is zero. y = 4+30t - 16t^2 is the formula, where
V = V(0) -32t
0 = 30- 32t
t = 15/16 seconds when its velocity is zero.
It is not at its maximum height but is falling.
Answer:
6 pounds of green candy
Step-by-step explanation:
Let r be the weight of red candy
Let g be the weight of green candy
Total weight = 10 pounds
r + g = 10 -------------------------(I)
Total cost = $ 38.50
2.50r + 4.75g = 38.50 --------------(II)
Multiply equation (I) by -2.50
(I)* (-2.50) -2.50r - 2.50g = -25.0
(II) <u>2.50r + 4.75g = 38.50 </u> {Now add and r will be eliminated}
2.25g = 13.50
g =13.50/2.25
g = 6
Plug in the value of g in equation (I)
r + 6 = 10
r = 10 - 6
r = 4
Answer:
The average rate of change from 7 to 60 minutes is 0.36 miles per minute.
Step-by-step explanation:
at x₁ = 7, f(x₁) = 8
at x₂ = 60, f(x₂) = 27
Using the formula to determine the average rate of change at which the total cost increases will be:
Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]
= [27 - 8] / [60-7]
= 19 / 53
= 0.36
Therefore, the average rate of change from 7 to 60 minutes is 0.36 miles per minute.
Rememeber thath you can do anything to an eqation as long as you do it to both sides
12a-7+12a=13
add like terms
24a-7=13
add 7 to both sides
24a=20
divide both sides by 24
a=20/24
a=5/6
