Question

4.9t^2-225t+620=0

Answer 1

numbers are too ugly. multiply all by 10, then apply quadratic formula x= (-b+||- sqrt (b^2-4ac))/2a

Answer 2

Do you know what that would be still alittle lost.

Answer 3

\[t=(-b \pm \sqrt(b^2-4ac))/2a\]
you know that (after multiplying by 10), a is 49, b is -2250, c is 6250. Sorry numbers are too huge, but we got calculators.
