Reading the news on the internet, johan comes across the headline, “when stress is increased, men rush ahead, women more cautious.” (this headline is based on a study conducted by lighthall et al., 2011.) in this study, men and women were asked to perform a decision task as many times as possible in a set period, in a stressed or unstressed condition. in the unstressed condition, men and women performed similarly. however, with stress the number of decision tasks performed by men increased while the number performed by women decreased. which of the following is a variable in this study? 1. the decision task type2. the length of the set period3. the amount of stress4. the cause of the stress

step-by-step explanation:

65

step-by-step explanation:

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! : )
