Suppose x=d(t) represents the distance travelled in kilometers by a runner after t minutes. Assumed(t) is invertible. a.) Write a sentence that represents the following equation: d(5) = 3/2
b.) Write a sentence that represents the following equation:d^−1 (5) = 30
c.) Write two equations that represent the following sentence: The runner travelled 9 kilometers in the first hour.

step-by-step explanation:

1. the cylinder is a. 54

2.   a.108 /

depending on others is critical to survival. my source is apex!

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!
