Suppose the population of a country in 1985 was 145 million. in 1995 it was 190 million. use the formula p = ae kt to setup an expression to estimate the population of the country in 2005.
a. p = 145e10k
b. p = 145e20k
c. p = 190e10k
d. p = 190e20k

Option B is correct

The expression to estimate the population of the country in 2005 is given by

Step-by-step explanation:

Since we have given that

In 1985, there was population of 145 millions.

Similarly,

In 1995, there was a population of 190 million .

Use the formula,

where A denotes the initial population and t denotes the number of years.

So, the expression becomes

∵ time period between 1985 to 2005 is 20 years.

So we take t=20 years.

So, the expression to estimate the population of the country in 2005 is given by

i do not know the answer

step-by-step explanation:

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
