Rafael is a virologist who wants to determine the number of people who might be affected by a particular disease 30 years from now. The virologist knows there are 600 people infected with the disease now, and the spread of the disease has a growth rate of 0.085 per year. What is the number of infected people 30 years from now?

1,530 people

Step-by-step explanation:

First do 0.085 times 600 to get 51 (this stands for 51 new ppl per year)

Second Do 51 times 30 to get 1,530

1,530 will stand for infected ppl of this disease in 30 years

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

they would have to work 32 hours.
