The number N of bacteria present in a culture at time t (in hours) obeys the equation N = 1000e^0.01t After how many hours will
jasenka [17]

Answer: N(t) = (2^t)*1500

Step-by-step explanation:

Let's define the hour "zero" as the initial population.

So if N(t)  is the number of bacteria after t hours, then:

N(0) = 1500.

Now, we know that the population doubles every hour, so we will have that after one hour, at t = 1

N(1) = 2*1500 = 3000

after two hours, at t = 2.

N(2) = 2*(2*1500) = (2^2)*1500

After three hours, at t = 3

N(3) = 2*(2^2)*1500 = (2^3)*1500

So we already can see the pattern, the number of bacteria after t hours will be:

N(t) = (2^t)*1500

Builders are covering a wall that is 4 meters tall and 7 meters wide with bricks. They will cover the entire wall except for a s
marin [14]

Answer:

24 m^2

Step-by-step explanation:

There are two areas to consider here:  first, the area of the wall, and second, the area of the window.  We answer this question by finding these two areas and subtracting the area of the window from the area of the wall.

Wall area:  (4 m)(7 m) = 28 m^2

Window area:  (2 m)(2 m) = 4 m^2

Net area of wall, to be covered in brick:

28 m^2 - 4 m^2 = 24 m^2
