Question

M is partly constant and partly varies as n square when n=2,m=17 and when n=2,m=53 find (a)the equation conneting m and n (b)n when m=32

Answer 1

m = a + bn^2
so, using the two data points,
a+4b=17
a+4b=53
How can m be both 17 and 53 when n=2? Fix that and then solve for a and b, and then you can find n when m=32

Answer 2

32×4=
