Answer:
32 > 23.
Step-by-step explanation:
We are given with 32 and 23. We need to compare them. If we use number line 32 is always greater than 23.
So, 32>23
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.
Answer:
1.6
Step-by-step explanation:
Lets count how many points are x and y away from each other since we dont have a graph.
X and Y points:
35-15=20
56-24=32
Use the formula:
32/20 = 1.6
Answer:
k = 3 1/5
Step-by-step explanation:
We want to isolate k, or move all numbers to the other side.
1/2 (4 - k) = 2/5
(4 - k) = 2/5 * 2
-k = 4/5 - 4
k = 4 - 4/5
k = 3 1/5
