Answer:
1. 17.59
2. 81.68
3. 8.99225
4. 12.00028
Step-by-step explanation:
for the first two you have to multiply the radii by 2 to find the diameter, then multiply your diameter by pi (3.14) to find the circumference
for the second two you have to work backwards so you have to divide the circumference by pi (3.14) which will give you the diameter, then you have to divide the diameter by 2 to get the radius.
Answer:
a) a x 12
b) p x 4
c) (a x 12) + (p x 4)
Step-by-step explanation:
These are the answers because:
1) Since a is representing the cost of each apple, we have to multiply the a with 12.
2) Since p is representing the cost of each pear, we have to multiply the p with 4.
3) Finally, for c, each basket contains 12 apples and 4 pears. Therefore, we just use our eautions from before and add them which will give you the total cost of one basket.
Hope this helps! :D
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.
