Answer:There is no need for rounding because 2 is the hundredths place so it's still 0.42
Step-by-step explanation:
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.
10 inches squared. Area is length times width. 15/2 x 4/3 = 60/6 = 10^2.
Answer:
if you are solving for y then the answer is 2x-5
Answer:
145
Step-by-step explanation:
A+B=180
so,180-35=145.
