  191.4

Step-by-step explanation:

Set E includes all the numbers in the first row. Set D includes all the numbers in the right-most column. (7.6 is included in both those sets, but should be added only once.)

Set E∪D is the sum of those numbers:

  E∪D = 120.1 +25.7 +24.4 +7.6 +2.2 +0.8 +10.6 = 191.4

The set E∪D includes 191.4 million humans.

gdp is the best phrase!

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! : )
