You wish to make an investment of $9,000 at 7% interest. How much will your investment be worth in 40 years at simple interest, compounded
quarterly, and compounded continuously?

A = $ 144,460.59

Step-by-step explanation:

A = $ 144,460.59

First, convert R percent to r a decimal

r = R/100

r = 7%/100

r = 0.07 per year,

Then, solve our equation for A

A = P(1 + r/n)nt

A = 9,000.00(1 + 0.0175/4)(4)(40)

A = $ 144,460.59

Sum:

The total amount accrued, principal plus interest,

from compound interest on an original principal of

$ 9,000.00 at a rate of 7% per year

compounded 4 times per year

over 40 years is $ 144,460.59.

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.
