The birth rate of a population is b(t) = 2500 e0.021t people per year and the death rate is d(t)= 1470 e0.019t people per year, find the area between these curves for 0 ≤ t ≤ 10. (round to the nearest integer.)what does this area represent? (attention! you are allowed only two submissions for this answer.)the number of births over a 10-year periodthe number of years it takes to increase the population by 10,000,000the number of years it takes to increase the population by 10the change in population over a 10-year periodthe number of deaths over a 10-year period

110,323.7505 or 110,324

Step-by-step explanation:

We need to take the integral of b(t) - d(t) over the interval of [0, 10].  This will tell us the average population over a 10 year period.  

We are counting all the birth (additions to the population) and counting the deaths (subtractions to the population), so overall population is calculated by:

Population = birth rate - death rate

We take the anti derivatives of b(t) and d(t),  see all work on the attached photo

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
