So the equation you'll use is (18,000 × .041)y+18000. Y is your years which is 20. So all you need to do is plug it in to get (18,000 × .041)20+18000 and when solved is 32,760 downloads by 2030
(-3,4)(0,-3)
slope = (-3 - 4) / (0 - (-3) = -7/3 <=
To simplify square root 27, find two numbers that equal 27. But also, one of the numbers should be a perfect square (such as 4, 9, 36...).
9*3=27. The square root of 9 is 3, which makes it a perfect square. So, the answer is A.
