In the last ten years, the population of Brazil has grown at an exponential rate of 0.8% per year to 205,832,675. If this rate continues, what will be the population in 10 more years? I try to solve different way, but it's incorrect, I don't know what to do.

i would pic false cause it goes down towards negative

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

9x
