Aboat takes 3.6 h to travel downstream from its dock to a fishing hole. if the water were still, it would have taken 4.5 h to make the trip. let x represent the speed of the boat and let y represent the speed of the water. (a) write an expression for the distance traveled in moving water, using 3.6 h for the time. then write an expression for the distance traveled as if in still water, using 4.5 h for the time. (b) set the expressions in part (a) equal to each other. then solve the equation for y. show your work. (c) what percent of the boat’s speed is the water current?

the ratio of grapes to blueberries she should use is 12: 3

step-by-step explanation:

if mandie is making 15 cups of fruit salad, the ratio of grapes to blueberries she should use is 12: 3.

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! : )
