Cindy has three cats and they live to jump in and out of their cat foot. yesterday the cat door was used 109 time by her cats. sammy used it for 1/4 of the times and tomy used it for 3/10 of the time. how many times did suzuki use the cat door? . justify your answer to the following problem by explaining why you chose this strategy.

9/20

Step-by-step explanation: Suzuki used the cat door 9/20 times. I know because 3/10+¼=11/20 and since 20 is my whole all I have to do is subtract 11 from 20 and that equals 9/20.

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! : )
