By definition we have to:
 A set has under an operation if performance of that operation on set members always produces a member of the same set; in this case we also say that the set is closed under the operation.
 For this case we have the following polynomials:
 4x ^ 2

x ^ 2 + 3x + 7
 Multiplying we have:
 (4x ^ 2) (x ^ 2 + 3x + 7) = 4x ^ 4 + 12x ^ 3 + 28x ^ 2

 The product of two polynomials is also a polynomial.
 Answer:
 
d 4x ^ 4 + 12x ^ 3 + 28x ^ 2 is a polynomial

Your bank granted you a single payment loan of 2,500 for 90 days at 10 percent interest. What is the interest on the loan?
viva [34]

Answer:

62.5 interest on 2500 loan

Step-by-step explanation:

Given that,

amount of loan bank has granted = 2500

number of years = 90 days

                              90 days   = 3 month

                              3 months = 1/4 year = 0.25 year

interest rate = 10%

                     = 10 / 100

                     = 0.1

Formula to use

Principal * interest rate expressed as a decimal * time in years

2500 * 0.1 * 0.25

62.5

Hence, the interest on the loan of 2500 with 10% interest rate for 90 days is 62.5
