In 1998, the population of country C was 38 million, and the exponential growth rate was 1% per year

Step-by-step explanation:

Formula for the exponential graph is given by the function,

Where = population after 't' years

= Initial population

r = rate of increase

t = Number of years

In 1988, population of a country C was 30 million.

A). Function for the population will be,

B). Population in year 2020,

           = 47.30 million

C). Doubling time means the duration in which becomes .

  By taking log on both the sides of the equation,

  t[log(1.01)] = log2

  t =

    =

  t = 69.66 years

answer: the equation matches the regression

step-by-step explanation:

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
