Answer:
8
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube
Remember that all the spheres are similar
Let
z ----> the scale factor
V_1 ---> the volume of the large sphere
V_2 ---> the volume of the small sphere

<em>Find the scale factor</em>
we know that
The radius of the large sphere is double the radius of the small sphere
so
The scale factor is 2

substitute the value oz z




The volume of the large sphere is 8 times the volume of the small sphere
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:
A, B, and B.
