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: You Would have To know How Far it will go In the next 60 min. (c
Step-by-step explanation:
A = amount of adult shirts sold
c = amount of child shirts sold
140 = 4a + 2c
Check the picture below, notice the distance from the focus to the directrix
bear in mind that, the vertex is a distance "p" from the focus point and a distance "p" from the directrix, that simply means, the vertex is half-way between both of those fellows
in this case, the focus point is above the directrix, that means, the parabola is vertical and opens upwards, "p" is a positive number for the focus/point form
so.. check the graph, you know what h,k are, and p, so, plug them in
