Two groups of staff at a store are making flowers to decorate the entrance. if group a were to do it alone, it would take them 10 hours to complete the task. if group b were to do it alone it would take them 15 hours. the groups decided to work together. group b took a break for 1 hour and 40 minutes. group a ended up making 300 more flowers than group b. how many flowers are there altogether?

Step-by-step explanation:

Let x be the number of flowers. If Group A were to make x flowers alone, it would take them 10 hours to complete the task, then they make flowers in an hour.  If Group B were to make x flowers alone, it would take them 15 hours to complete the task, then they make flowers in an hour.

The groups decided to work together. They can make together in an hour and it takes them hours. Group B took a break for 1 hour and 40 minutes ( hour), then Group B works

hours.

Thus,

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! : )
