2 Which situation BEST describes a direct variation? A. Each of the diners at a table will leave a $3 tip. The more diners sitting at a table, the greater the total tip
B. A manager estimates that a construction project will take 60 days with 2 workers. The more wodass hired, the fewer the days to complete the project.
O A hot dog stand owner opens her store with 500 hot dogs. The fewer the number of hot dogs cooked, the greater the number of hot dogs uncooked
O A truck driver fills the gas tank in a truck to start a 100-mile trip. The farther the driver travels, the less gasoline will be left in the gas tank of the truck

answer: a clock

step-by-step explanation:

55? i think maybe

step-by-step explanation:

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! : )
