Answer:
81 times the original size
Step-by-step explanation:
AA0ktA=3A0=?=?=25hours=A0ekt
Substitute the values in the formula.
3A0=A0ek⋅25
Solve for k. Divide each side by A0.
3A0A0=e25k
Take the natural log of each side.
ln3=lne25k
Use the power property.
ln3=25klne
Simplify.
ln3=25k
Divide each side by 25.
ln325=k
Approximate the answer.
k≈0.044
We use this rate of growth to predict the number of bacteria there will be in 100 hours.
AA0ktA=3A0=?=ln325=100hours=A0ekt
Substitute in the values.
A=A0eln325⋅100
Evaluate.
A=81A0
At this rate of growth, we can expect the population to be 81 times as large as the original population.

Step-by-step explanation:
Answer:
y intercept: (0,-13)
x intercept: (13/5, 0)
Step-by-step explanation:
To find the y intercept, x has to equal zero. So, plug it in. The equation becomes y=-13.
Since x is zero, the point becomes (0,-13)
To find the x intercpet, y has to equal zero. So, plug it in. The equation becomes 0=5x-13.
move 13 to the other side
13=5x
divide by 5
13/5=x
Since y is zero, the point becomes (13/5,0)
hope this helps!
.Kim is x years old. Jordan is 7 years older than Kim. Four times Jordan’s age is equal to 200. (a)Write an equation that could be used to solve for Kim’s age, x. (b)How old is Kim? (c)How old is Jordan? Answer:
Kim = x
Jordan = x + 7
4(x+7) = 200
4x + 28 = 200
4x = 200 - 28
4x = 172
x = 172/4
x = 43. Kim's age
Jordan: x + 7 → 43+7 = 50
Answer: 5
