What number can you add to 2√ to get a rational number? 12 2 0 −2√ from 2000 to 2015, the amount of newspapers sold in a town declined to 25,000. the number is expected to decline at a rate of 3.7% each year. how many newspapers will be sold in 2030? round to the nearest whole number. enter your answer in the box.

Question #1.

√2 is an irrational number. There is no way to make it rational using an addition unless the number that is added to √2 is the opposite to itself, that is, –√2 since we know that the sum of two opposite numbers is 0. Hence, √2 + (–√2) = 0, which is a rational number.

Thus the answer is –√2.

Question #2.
The number of newspapers after t years from 2015 can be modeled by the equation:

where  = number of paper at the year 2015,
r = declination rate.

In this case, , r = 0.037, t = 2030 – 2015 = 15.
Plugging them in the equation, we get



The answer is 14,202.
