Answer:
972pi
Step-by-step explanation
Equation of sphere volume = 4/3pir^3
4/3*9^3*pi = 972pi
Suppose she plants t trees, and each one yields a apples per tree, therefore:
a = 140 - 4((t - 100)/10)
a = 140 - 0.4t + 40
a = 180 - 0.4t
If y is the total yield for the orchard, we have:
y = ta
y = t(180 - 0.4t)
y = 180t - 0.4t^2
dy/dt = 180 - 0.8t
To maximize y, set the derivative to zero:
0 = 180 - 0.8t
0.8t = 180
t = 180 / 0.8
t = 225 hope this helped
Answer:
Please clarify your question
Step-by-step explanation:
Answer:
First blank: non-viable solution because the costs aren't less than the revenue
Second blank: viable solution because the costs are less than the revenue
Step-by-step explanation:
First: Insert the x into the equation and work it out to see if it is less than the y.
(30,90) x=30 y=90
y=1.5(30)+45
y=45+45
y=90
Non-Viable
Second: Insert the x into the equation and work it out to see if it is less than the y.
(60,160) x=60 y=160
y=1.5(60)+45
y=90+45
y=135
Viable
(hope this helps :P)
