a country's population in 1992 was 50 million. in 2002 it was 53 million. estimate the population in 2010 using the exponential growth formula. round your answer to the nearest million

59 million

Step-by-step explanation:

Due to the way exponents work, we first take that the difference from 2002 to 2010 is 4/5 the difference from 1992 to 2002. The total amount that the population is in 2002 compared to 1992 is 1.15. 1.15^(4/5)*53 million is roughly 59 mil :)

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

the answer is 13 cm
