Hello!
The variable "n" represents an exponent.
An exponent is used to multiply a number (b) by itself "n" times. For example, if the expression were to read (b²) it would represent the following:
b × b
The same could be said for (b³):
b × b × b
Even (

):
b × b × b × b × b × b × b × b × b × b
I hope this helps!
21+4(32-5)=448
I think it’s 448
Answer:
15.84%
Step-by-step explanation:
There is no formula that will tell you the interest rate. It must be computed iteratively or found graphically. A financial calculator can do the work for you.
The parameters this one uses are
- number of payments (24)
- the amount financed (1925 -125 = 1800)
- the monthly payment, negative because it is being paid (-88.00)
- the remaining balance after all payments (0)
- the number of payments per year (monthly = 12)
- the number of times per year interest is compounded (monthly = 12)
aApolynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.
There are 3 sets of polynomials; LINEAR, QUADRATIC and CUBIC
