hi im a newbie to mathes and have been doing calculus recently ive. Been given two formulas and need to intergrate them and solve the equation, ive had a good attempt at them. i would just like to confirm if they are corret.

2. Hello lukebushnell

The first is correct to 2 s.f. Or, to be exact, $5.525 \times 10^{-4}$.

The second is correct.

Good work!
