Adam and his dad share the cost of a meal in the ratio 2: 3, adam's dad pays £52.20, what's the total cost of the meal?

This is a proportion problem. Start by doing:

2/3 = x/52.20

Multiply both sides by 52.20

X= 34.8 this is how much the son paid

Now add 34.8 + 52.20

Answer is 87

the square root of what number? if you add that, then someone will probably answer the question.

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! : )
