Answer:
45.05
Step-by-step explanation:
The answer is 45.05 because I multiplied ( b and a) 8.5x5.3 and then I got 45.05.
Answer:
Step-by-step explanation:
Given that during the period from 1790 to 1930, the US population P(t) (t in years) grew from 3.9 million to 123.2 million. Throughout this period, P(t) remained close to the solution of the initial value problem.

a) 1930 population is the population at time t = 40 years taking base year as 40
We can solve the differential equation using separation of variables

Resolve into partial fractions

Integrate to get
ln P -0.00474/0.0001489 (ln (0.0001489P-0.03135) = t+C
ln P -31.833 (ln (0.0001489P-0.03135) =t+C

Limiting population would be infinity.
Answer:
Your answer is 2 1/2.
Step-by-step explanation:
Divide 9 pounds of sand into 4 buckets, or 9÷4. This equals 2.5 pounds of sand in each bucket.
6.25%=0.0625
P(t) = Initial Population * (1 + rate)^t
P(t) = 400,00*(1+0.0625)^t
P(t)= 400,00*(1+0.0625)^15
Pt=400
The answer and work are shown in the picture given.
