Alberto has a mass of 52.2kg and then gains 2kg . frank has a mass of 48.8 and then loses 3kg . after their weight change what is albee and frank's mass

After their weight change Alberto's mass is 54.2 kg and Frank's mass is 45.8 kg

Step-by-step explanation:

step 1

Find Alberto's mass after the change

Adds the kilograms he gains to its original mass

52.2+2=54.2 kg

step 2

Find Frank's mass after the change

Subtract the kilograms he losses from its original mass

48.8-3=45.8 kg

therefore

After their weight change Alberto's mass is 54.2 kg and Frank's mass is 45.8 kg

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! : )
