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
9/10 is .9
51 subtracted by 6 is 45
45 multiplied by .9 is 50
.9 multiplied by 50 is 45
45 plus 6 is 51
So you missing number would be 50.
Hope this helps!
3.675v + 0.096v^2.....where v is the speed of the car in mph
at 70 mph....so sub in 70 for v
3.675(70) + 0.096(70^2) =
257.25 + 470.4 =
727.65 ft <===
