Answer:

perimeter is 12x-6

Step-by-step explanation:

perimeter is the sum of all sides

3(x+2) + 2x+11 + 7x-23

distribute the 3 in the first term, then combine 'like terms'

3x+6 + 2x+11 + 7x-23

3x+2x+7x + 6+11+(-23)

12x-6

If $190 is invested at an interest rate of 11% per year and is compounded continuously, how much will the investment be worth in

dangina [55]

Answer:

$295.01

Step-by-step explanation:

Using the compounding continuously formula, we are looking for A. We have that P = 190; r = .11 (always use the decimal form of the rate!); and t = 4. Filling in we have:

$A=190e^{(.11)(4)}$

Simplifying that multiplication:

$A=190e^{.44}$ .

On your calculator, raise e to the .44 power to get

A = 190(1.552707219) and

A = $295.01
