Asmall leak is causing a swimming pool to lose 12 gal of water/h. what is the change in the amount of water in 4 h? a. −4 gal b. −2 gal c. 2 gal d. 4 gal

None of your answers make sense.  

After 1 hour, you lose 12 gallons

After 2 hours, 24

After 3 hours, 36

After 4 hours, 48 gallons.

The answer would be -48 but that's not a choice given.

x=half

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! : )
