Acar passes point a going 60 kph. fifteen minutes later a second car going in the same direction passes point a going 80 kph. assuming that both cars are maintianing a constant speed and continue on the same highway, how long will it take before the second car catches up to the first one

means if you're already damaged some way when you take out a medical insurance you will not get full compensation for that injury that you already have.

its a straight line parallel to the time axis

7/2

welcome ; )

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!
