Jean's parents received an economic stimulus check of $3900 and decided to use it to
start a college savings fund for her. They invested all the money in an account that
gives 4.5% compound interest each year. Create an equation, table and graph where x is
the number of years and y is the amount of money in the account to represent the
situation. Your table and graph should show how much money will be in the account for
the first 8 years. How many years until the original $3900 in the account would double?

it would rotate about 180 degrees.

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!
