Answer: 180

Step-by-step explanation:

This is just testing if you know the sum of cubes formula:

$a^3 + b^3 = (a+b)(a^2 - ab + b^2) = (a+b)((a+b)^2 - 3ab)$

Plugging in the respective values, you get

$a^3 + b^3 = (6)(6^2 - 3(2)) = \boxed{180}$

Find cot θ if csc θ = negative square root of thirty seven divided by six and tan θ > 0.

Ket [755]

You can use the trigonometric identity $1+\cot^2{x}=\csc^2{x}$ .

$1+\cot^2{\theta}=(\frac{-\sqrt{37}}{6} )^2 \\ 1+\cot^2{\theta}=\frac{37}{36} \\ \cot^2{\theta}=\frac{1}{36} \\
\cot{\theta}=\frac{1}{6}$

The requirement that $\tan{\theta}\ \textgreater \ 0$ eliminates -1/6 from being another solution.

Step-by-step explanation:

10^4 x 100=10^4 x 10²

=10^(4+2)

=10^6

Then:

10^6/10^6=10^(6-6)=10^0=1 day
