You ride through some wet paint on your bike, creating a red spot on the tire. Write a cosine equation to model the height of the red spot over the distance you ride . Your bike tire has a radius (r) 13 inches The period is the circumference of the tire (2pi * r) Start the cycle when the spot is at the top of the tire.

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

i would be 2,000 just get the square root of 50 which is 2500 and the divid 4/5 and last thing multiply the answer you get for that by the square root of 50
