Question

What is the answer to 0=t^3 - 5t, I need to find the t's.

Answer 1

\[t = \sqrt{5}\]

Answer 2

t( t^2 - 5) = 0
t^2 - 5 = 0
t^2 = 5
Therefore, \[t = \sqrt{5}\]

Answer 3

It is asking for the intersection of x(t) = t^2 and y(t) = t^3 - 5t
I got sqrt5 for the x function, but I think I need at least two t's, right?

Answer 4

t( t^2 - 5) = 0

so
t=0
and
t^2-5=0
t^2=5
\[t=\pm \sqrt{5}\]

Answer 5

ok, thank you
