Suppose you invest semiannually for 25 years in an annuity that pays 5% interest, compounded semiannually. At the end of the 25 years, you have $500,000. How much of this totalis interest? Enter your answer rounded to the nearest hundred
dollars.

the answers are in the images, i received 100% on this assignment. hope this !

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

x = 3 ± √(5+y)

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!
