2. The cone has a radius of 30 mm and slant height of 34 mm. What is the height h for this cone?

Flura [38]

Answer:

h = 16

Step-by-step explanation:

By applying the Pythagorean Theorem, the slant height is given by the formula:

$\sqrt{r^2+h^2}$

34 = $\sqrt{30^2 + h^2}$

$34^2 = 30^2 + h^2$

$1156 = 900 + h^2$

$256 = h^2$

$h = \sqrt{256}$

$h = 16$

Square root of 2 divided by the cube root of 2

kifflom [539]

Answer: $\sqrt[6]{2}$

Step-by-step explanation:

You know that the expression is $\frac{\sqrt{2}}{\sqrt[3]{2}}$

By definition we know that:

$\sqrt[n]{a}=a^{\frac{1}{n}$

You also need to remember the Quotient of powers property:

$\frac{a^n}{a^m}=a^{(n-m)}$

Therefore, you can rewrite the expression:

$=\frac{2^{\frac{1}{2}}}{2^{\frac{1}{3}}}$

Finally, you have to simplify the expression. Therefore, you get:

$=2^{(\frac{1}{2}-\frac{1}{3})}\\=2^{\frac{1}{6}}\\=\sqrt[6]{2}$
