To find the population after a year, you can multiply 4.5x10⁸ by 1.05, as it increases by 5% per year (1.05=1+5%). To find the population after five years, you have to multiply 4.5x10⁸ by 1.05 five times.

4.5x10⁸(1.05)⁵

=574326703.125

Since you can't have a decimal amount of people, you round this number to 574326703.

Therefore, the population after five years is going to be about 574326703.

Given that < DAB and < DCB are right angles and m < DBC = 42, what is the measure of CAB

zhenek [66]

Please consider the attached diagram.

We have been given that angle DAB and angle DCB are right angles. We are also told that measure of angle DBC is 42 degrees. We are asked to find the measure of arc CAB.

We can see that angle DBC is inscribed angle of arc DC, so measure of arc DC is two times the measure of angle DBC.

$\widehat{DC}=42^{\circ}\times 2=84^{\circ}$
