Asked by BWAMBALE ISAAC

A quantity c partly varies as n and partly varies as the square of n. when c=22, n=2 and when c=115, n=5. find the: (i)equation connecting c and n.
Answered by Steve
c = an+bn^2
Now, using the points (2,22) and (5,115) solve for a and b:
2a+4b = 5
5a+25b = 115 or, dividing by 5, a+5b = 23
