A car travels 204 miles in 4 hours and 15 minutes. How many miles does it travel per hour?

48 miles per hour

Step-by-step explanation:

To calculate the speed you would divide the distance of 204 miles by the time of 4 hours and 15 minutes. Then you should divide the distance by the time

1) you should first divide the minutes by 60 to convert it into a decimal.

2) After divide the distance by 4.25 to work out the speed.

207/8 is the right

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
