32 miles to get to 34 because after the first 2 it is a continuous 1 mile every track practice until he gets to 34 miles, so 34-2= the 32 miles he must run.
We use the fact that x2+y2=1 This is the equation of the unit circle. We know that x=-4/5, so plug this in and solve for y x2+y2=1 <span>(−4/5)^2+y2=1</span> 16/25+y2=1 y2=1−16/25 y2=9/25 <span>y=−square root of 9/ 25</span> y = -3/5
