In 1987, the population of country A was estimated at 87 million people, with an annual growth rate of 3.5%. The 1987 population

KATRIN_1 [288]

Answer:

Step-by-step explanation:

Given that in 1987, the population of country A was estimated at 87 million people, with an annual growth rate of 3.5%

Thus the equation for population for country A would be

$P(A) = 87e^{0.035t}$

The 1987 population of country B was estimated at 243 million with an annual growth rate of 0.6%.

So equation for population for country B would be

$P(B) = 243e^{0.006t}$ where t = time in years and P in millions

a) P(A) = 2*87 when

$2=e^{0.035t}$

Take log and solve

ln 2 = 0.005 t

t = 138.63

Thus after 138 years population will double for A

b) P(A) = P(B) when

$P(A) = 87e^{0.035t}=P(B) = 243e^{0.006t}\\e^{0.035t-0.006t}=\frac{243}{87} =2.793\\0.029t = 1.027\\t= 35.42$

Approximately after 35.5 years the populations of both countries would be equal.

The graph shows two lines, A and B.

Harlamova29_29 [7]

Answer with explanation:

One solution.

The number of points of intersection represents the number of solutions. Since the two lines only intersect at one point, there is only one solution.

(3, 4)

The point(s) of intersection marks the solution(s) to the lines. Since lines A and B intersect at the point (3, 4), the solution to the equation of their lines is (3, 4), or $x=3, y=4$ , as coordinates are written as (x, y).
