hope this helps
A = L * W = 75 so L = 75/W Cost = 4W + 8(2L + W) = 4W + 16L + 8W = 12W + 16L = 12W + 1200/W C' = (12(W^2 - 100))/(W^2) = (12(W-10)(W+10))/(W^2) so W = 10 then L = 7.5
Answer:
$203.02
Step-by-step explanation:
Since the bank in question compounds interest continuously, the following equation should be used to determine the final balance (B) in April's account:

Where "e" is a mathematical constant approximated as 2.7183, "i" is the interest rate (1.5%) and "t" is the investment time in years (1):


April's balance would be $203.02 after one year.
Answer: 0
Step-by-step explanation:
To find the slope, you would need to use the formula
.

The slope is 0, meaning the line is horizontal.
Answer:
t ≤ 11 (or all values 11 or less)
Step-by-step explanation:
8t - 9 ≤ 79
<em>So, I am assuming you are trying to find the value(s) of "t".</em>
Add 9 to both sides.
8t ≤ 88
Divide 8 by both sides.
t ≤ 11
ANSWER
t ≤ 11
