15. determine the future value of $4,000 deposited into an ordinary
annuity after each quarter for 3 years at 6% interest compounded
quarterly. (lesson 5.8)

The future value of investment at 6 % compounded quarterly is                $ 4782.472  

Step-by-step explanation:

Given as :

The principal amount = $ 4000

The rate of interest compounded quarterly = 6 %

The time period = 3 years

Let The future amount = A

From Compounded method

Amount = Principal ×

Or, Amount = 4000 ×

Or, Amount = 4000 ×

Or, Amount = 4000 × 1.195618

∴ Amount = $ 4782.472

Hence The future value of investment at 6 % compounded quarterly is  $ 4782.472  Answer

i think 1: 2

step-by-step explanation:

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
