What is the world’s predicted population in the year 2020, rounded to the nearest million?

B

Step-by-step explanation:

Given

P_0=5642000000 people

Growth Rate=i=1.3%

Since the years will be counted from 1994

So for 2020 population:

n=26 years

Using the formula,

P_n= P_0 e^in

Putting the values,

P_n=(5642000000)*(2.71828)^(0.013*26)

P_n=(5642000000)*1.40214

P_n= 7910874921.6228

Rounding off to nearest million

P_n= 7911000000 people

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
