A rational number is a number that can be written as a ratio. That means that it can be written as a fraction. The numerator and the denominator both need to be whole numbers for it to be rational. For example, 2 is a rational number because it can be written as the fraction 2/1.

169 is the square of 13, but not the cube of a rational number.

The statement is false.

A. What is the monthly payment for a<br>$3,200 five-year loan with an APR of 3%.​
madreJ [45]

Answer:

$57.50

Step-by-step explanation:

we know that

The monthly loan payment formula is equal to

M=\frac{P(\frac{r}{12})(1+\frac{r}{12})^{12t}}{(1+\frac{r}{12})^{12t}-1}

where

M ----> is the monthly payment

P ---> the amount borrowed

r ---> interest rate as decimal

t ---> length of the loan in years

we have

t=5\ years\\ P=\$3,200\\ r=3\%=3/100=0.03

substitute in the formula

M=\frac{3,200(\frac{0.03}{12})(1+\frac{0.03}{12})^{12(5)}}{(1+\frac{0.03}{12})^{12(5)}-1}

M=\frac{3,200(0.0025)(1.0025)^{60}}{(1.0025)^{60}-1}

M=\$57.50
