Find the equation of a circle that has a diameter with the endpoints given by the points AC -4,-2) and B(4,2) A (X-0)2 + (y-0)2 = 20
B (x+4)2 + (y - 2)2 = 81
© (x + 5)2 + (y + 4)2 = 4
(x-4)2 + (y + 5)2 = 81

Welp life just is hard

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
