8. An acidophilus culture containing 150 bacteria doubles in population every hour. The formula y = 150(2)^t can be used to model the bacteria population where y is the population of the colony t
hours after its initial population was recorded.
a. How many hours did it take for the colony to reach 1 million bacteria?
b. What will be the population of the colony after 8 hours?

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

12.5 feet

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

900 degrees
