Jami is trying to model the movement of a tire. in order to properly model the movement, she is going to focus on the movement of the tire's air nozzle. the nozzle is on the right side of the tire and she is going to treat that position as the equilibrium position. she then slowly rotates the tire so that the nozzle goes up at the beginning of the rotation, and follows its change in height. the distance of the nozzle from the center of rotation is nine inches. she finds that it takes eight seconds for the tire to make a single revolution. which of the following functions best models the position of the nozzle?

stops on an even number.

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!
