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

Perry Mazza wants to borrow $30,000 from the bank. The interest rate is 6% and the term is for 5 years. What is the amount of in
omeli [17]

Answer: In both the case amount of interest is paid are:

1) $9000

2) $10146.76

Explanation:

Since we have given that

Principle amount = $30000

Interest rate = 6%

Number of years = 5 years

we'll use " Simple interest " first,

As we know the formula for " Simple Interest ":

I=\frac{P\times R\times T}{100}\\\\I=\frac{30000\times 6\times 5}{100}\\\\I=$9000

Now, we'll do it by "Compound Interest "

Amount=P(1+\frac{r}{100})^n\\\\Amount=30000(1+\frac{6}{100})^5\\\\Amount=$40146.76

So,

Interest = Amount-Principle\\\\Interest =40146.76-30000\\\\Interest =\$10146.76

Hence in both the case amount of interest is paid are:

1) $9000

2) $10146.76

Suppose point e has a coordinate of 11​, and eg= 8. what are the possible coordinates of point​ g?
viva [34]

So I will be assuming that EG = 8 is the length of the line segment EG. If that's the case, therefore the coordinates of G would simple be:

G =11 ± 8

G = 11 – 8, 11 + 8

G = 3, 19 

<span>So G can have a coordinate of 3 or 19.</span>
