The human population doubles approximately every 50 years. If there were 2.5 million people in 1950, how many people are forecasted to populate the earth in 2100? First complete the equation: Future amount= ?(1+?)^?

The human population doubles approximately every 50 years

To Find:  If there were 2.5 million people in 1950 how many people are forecasted to populate the earth in 2100

Solution:

Equation for growth =

where a is the initial amount

y is the amount after x years

x denotes the time

A.T.Q

So, 20 million people are forecasted to populate the earth in 2100 .

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
