Apopulation of bacteria doubles every 18 hours. initially, the population of bacteria is 50. what is the population of the bacteria after 60 hours?

666.7

Step-by-step explanation:

We know the bacteria double every 18 hours. The initial population is 50.

After 18 hours - 100

After another 18 hours - 200

After another 18 hours - 400.

We are now up to 54 hours. With just 6 more hours to go, by how much does the bacteria increase? 6 hours is 1/3 of 18 or 0.3333.... If we had another 18 hours the bacteria would have grown to 800. Instead it grows a 1/3 of this.

The bacteria is 400+266.67 = 666.7 at 60 hours.

y/x=18

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! : )
