What is sandra's fastest recorded lap time? sandra's lap times (minutes) 2.4 2.3 1.7 1.8 2.7 2.6 1.9 1.5 1.2 1.4 1.3 1.4

Fastest means highest speed. Speed is the ratio of distance to time, the

fastest lap time is when the time taken to complete a lap is least.

The given lap times in minutes in a tabular form are;

Sandra is running at the fastest speed, therefore, having the fastest

recorded lap time when the time to complete a lap is the least of the given

times.

The fastest lap time is the lap time that takes the minimum amount of time which is the lowest of the given values for lap times which is 1.2 minutes.

Therefore;

answer: it is a.,b.,d.

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!
