Here are the fuel efficiencies (in mpg) of 10 new cars. 28, 25, 30, 22, 16, 41, 35, 18, 52, 35
What is the percentage of these cars with a fuel efficiency less than 19 mpg?

20%

Step-by-step explanation:  

Cars that are less than 19  mpg : 16, 18  

2 cars have less than 19 mpg.  

2/10  cars have less than 19 mpg.  

To change fraction to percentage :  

divide the numerator by the denominator, then multiply the decimal by 100

2/10 = 0.2

0.2*100 = 20

20%

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.

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! : )
