Answer:

x = 22.5°

Step-by-step explanation:

DE // AB ∠DEA ≅ ∠EAB = 2x

ΔEAB: interior angles (180°-4x) + 2x + (180°-6x) = 180°

8x = 180°

x = 22.5°

Use the fact that the world population was 2560 million in 1950 and 3040 million in 1960 to model the population of the world in

zimovet [89]

Answer:

The populaton in year 1991 will be of 5178.9 million of people

and the population in year 2020 will be of 8524.60 million of people

Step-by-step explanation:

We measure the time t in years and let t=0 in the year 1950.

We measure the population P(t) in millions of people, then P(0)=2560 and P(10) = 3040.

Since we are assuming that dp/dt=kP, this theorem gives the following.

$P(t) = P(0)e^{kt}= 2560e^{kt}$

$P(10) = 2560 e^{10k} = 3040$

$k=\frac{1}{10} ln (3040/2560) = 0.0171$

The relative growth rate is about 1.7% per year and the model is

$P(t) = 2560e^{0.017185t}$

Year 1991 is equal in our formula to 41 and year 2020 is equal to 70. Replacing,

$P(41) = 2560e^{0.017185(41)}=5178.89$

$P(70) = 2560e^{0.017185(70)}=8524.60$

Therefore the populaton in year 1991 will be of 5178.9 million of people and the population in year 2020 will be of 8524.60 million of people
