Question 973700
The shape of a state park can be modeled by a circle with the equation x^2+y^2=1600. A stretch of highway near the park is modeled by the equation y=1/40(x-40)^2. At what points does a car on the highway enter or exit the park?
***
Find the points of intersection  of the two given equation
I don't know how to do it algebraically, but my graphic program shows entering the park from the left side at (0,40) and exiting the park on the right at  (40,0)
