An investment of $6,599.20 earns 4.2% compounded monthly over 7 years how much interest is earned on the investment

Interest earned on the investment is; $2237.31254875

Step-by-step explanation:

Given:  Principal (P) = $6, 599.20  r= 4.2% and t = 7 years.

Formula for annual compound interest, including principal sum is:

            .....[1]

where ;

A represents the total amount , including interest.

P represents the initial deposits

r represents the rate of interest

t represents the number of times that the interest is compounded per year

n represents the number time that interest is compounded per year

Here, n = 12

therefore,

Substituting the values of P= $6, 599.20  r= 4.2% and t = 7 years in equation [1];

Simplify:

A = $8796.51254875

We have to find the interest is earned on the investment;

Use the formula:

A = I + P or

I = A - P

where,

I represents the interest earned on the investment;

we have;

I = 8796.51254875 - 6559.20 = $2237.31254875

Therefore, the interest earned on the investment is; $2237.31254875

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

i believe the answer is the polygon, heptagon.
