Answer quickly for 5 stars and

emilio wants to invest $15,820 that he just received as a prize from a contest he entered. he researches certificates of deposit (cds) at two different banks. the details for his two best options are in the table below. both cds earn compound interest, which you worked on in exponential growth & decay. when interest is compounded, it is added to the account’s principal to become part of the money that earns interest.

1. determine which investment will earn emilio more interest.
first bank or bank west

2. how much more interest will he earn with that investment?

Bank West

$242.82

Step-by-step explanation:

To find which bank will yield more interest for Emilio, we can solve for the interest of each bank by using the Compound interest formula:

For the Bank West we have:

n = 4 Quarterly

t = 6 years

r = 3.8% or 0.038

P = 15820

Let's substitute them in the formula.

Now let's solve for the Interest. We subtract our total amount to the principal amount.

Interest = 19849.89 - 15820

Interest = 4029.89

Now let's solve for the First Bank.

n = 12 Monthly

t = 5 years

r = 4.3% or 0.043

P = 15820

Let's substitute them in the formula.

Now for the interest:

Interest = 19607.07 - 15820

Interest = 3787.07

This gives us:

Bank West Interest = $4029.89

First Bank Interest = $3787.07

So Bank West will earn more interest than First Bank.

To find how much more interest we subtract the interest of Bank West to First Bank.

4029.89 - 3787.07 = $242.82

step-by-step explanation:

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
