Assume that y varies inversely with x. if y=6.4when x=4.4, find y when x=3.2

Because y varies inversely with x, let
y = k/x
where k = constant.

When x=4.4, y=6.4. Therefore
k/4.4 = 6.4
k = 6.4*4.4 = 28.16

The required relation is
y = 28.16/x

When x = 3.2, obtain
y = 28.16/3.2 = 8.8

8.8

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
