Arada [10]

Answer:

5,477.63

Step-by-step explanation:

First, convert R percent to r a decimal

r = R/100

r = 6%/100

r = 0.06 per year,

Then, solve our equation for P

P = A / (1 + r/n)nt

P = 5,500.00 / (1 + 0.06/4)(4)(0.068448)

P = 5,500.00 / (1 + 0.015)(0.273792)

P = $ 5,477.63

Summary:

The principal investment required to get

a total amount of $ 5,500.00

from compound interest at a rate of 6% per year

compounded 4 times per year

over 0.068448 years

is $ 5,477.63.

mote1985 [20]

Answer:

Step-by-step explanation:

The given question is incomplete: find the complete question in the attachment.

- In this question, problem was set up correctly in the box.

- There is a mistake in the second row of the box.

It should be x |  -2x³ | x² | -5x

- Further calculations should be,

-2x³ + x² - 5x + 6x² - 3x + 15

= -2x³ + (x² + 6x²) + (-5x - 3x) + 15

= -2x³ + 7x² - 8x + 15
