Myra is cooking meat the double number line shows that he needs 12 hours too cook 5 kilograms of meat how long does myron need to cook 3 kilograms of meat

7.2 hours

Step-by-step explanation:

Myra is cooking meat the double number line shows that he needs 12 hours too cook 5 kilograms of meat

12 hours to cook 5 kilograms of meet

we need to find the number of hours needs to cook 3 kilograms

Let x be the number of hours to cook 3 kilograms

Make a proportion

solve for x

cross multiply it

Divide both sides by 5

so x= 7.2 hours

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.
