My guess is 9 hours, because since pipe a takes 12 hours and with pipe b it takes 9, it's 12-9=3 I think.

What is 3^-4 as a fraction?

nalin [4]

Hello there!

Remember the Negative Exponent Law. If we have a number with a negative exponent, we flop it over.

So our answer looks like so:

$\frac{1}{3^{4} }$

<h2>Therefore, our answer is: $\frac{1}{3^{4} }$ </h2>

Hope this helps you!

Solve 2 tan θ = 2 cot θ for all values of θ if θ is measured in degrees.

Nesterboy [21]

Answer:

2tanθ = 2cotθ

tanθ = cotθ

tanθ = 1 /tanθ

tan²θ = 1

tanθ = ±1

if tanθ = 1

θ = 45° + nπ (π = 180° , n is a natural number)

if tanθ = -1

θ = 135° + nπ
