ANSWER: V=19.9*(0.9144m)^3=15,2146416738816 m^3
1 yard =0.9144 m
We will take the 18.0 cubic yards, cross multiply with 0.9144 and then divide the result by one to get
13.76m3
Sure hope this helps
A = (12 x 8 x 3) + (1/2 x 8 x 6.9) + (1/2 x 8 x 7 x 3)
A = 288 + 27.6 + 84
A = 399.6 m²
Answer:
$7,562.5
Step-by-step explanation:
Given the function of the profit earned expressed as;
<em>f(p) =-40p^2+1100p</em>
To maximize the profit, df(p)/dp must be sero
df(p)/dp = -80p + 1100 = 0
-80p + 1100 = 0
-80p = - 1100
p = 1100/80
p = 13.75
Substitute p = 13.75 into the function
f(13.75) =-40(13.75)^2+1100(13.75)
f(13.75) = -7,562.5+15,125
f(13.75) = 7,562.5
Hence the symphony should charge $7,562.5 to maximize the profit.
