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

What does increase mean
Darya [45]
Increase- to be more significant in value, to be of more worth, to have a larger quantity.

Basically, if I said I added 2 to 5, that would be an increase.

2+5=7 7 is bigger than 5. 

If I subtracted 2 from 5, that would make a decrease in value.

5-2=3  3 is smaller than 5.

I hope this helps!

The product of 5 and 2 less than triple a number equals the product of 7 and 8 more than twice the number. What is the number?
Oksi-84 [34.3K]

Answer:Hi,

Let the number be x

Twice the number is 2x

Five less than twice the number is 2x-5, which is given as 9

Therefore, 2x-5 = 9

or, 2x = 9+5

or, 2x = 14

or x=7

Thus the number is 7.

Cheers

Your bedroom ceiling if 10 feet high and is two-thirds as high as the living room ceiling. Write and solve an equation to find t
timurjin [86]
Ht of ceiling = 10 ft which is two-thirds of living rm ceiling
Ht of living rm ceiling = 2/3x = 10 ft
2/3h = 10 ft
2/3h times 3/2 to solve for h = 10 times 3/2
h = 30/2
h = 15 ft
