Question

G is proportional to the square of t. If t=2 and g=64, find g when t=3.5.

Answer 1

`If\ g\ is\ proportional\ to\ the\ t^2\ we\ have\ proportion\\\\ g=64\ \ \ \ ---\ \ \ t^2=2^2=4\\\\\ g=?\ \ \ ----t^2=(3,5)^ 2=12,25\\\\ 4g=64*12,25\\\\ 4g=784\ \ |:4\\\\g=196\\\\ Answer\ is\ g=196\ for\ t=3,5.`
