Answer:

C. StartFraction 4 x Superscript 4 Baseline Over y Superscript 6 EndFraction

Step-by-step explanation:

<u>Fractional Powers </u>

The expression

\sqrt[m]{y^n}=y^{\frac{n}{m}}

can be used to reduce roots and fractional powers.

Another useful relation is

(y^n)^m=y^{n.m}

We are given the expressión

\left ( 16x^8y^{-12} \right )^\frac{1}{2}

It's equivalent to

(16)^\frac{1}{2}(x^8)^\frac{1}{2}(y^{-12})^\frac{1}{2}

=(4)(x^4)(y^{-6})

=\displaystyle \frac{4x^4}{y^{6}}

This corresponds to the option  

C. StartFraction 4 x Superscript 4 Baseline Over y Superscript 6 EndFraction

The volume of a cone, V, is represented by , where r is the cone’s radius and h its height.
Arlecino [84]
So the height will equal 95.50 inches.

So if you double the height the volume is 1800cm3 and that is double the original volume 

And if you double the height the volume is 3600cm3 and that is the triple the original volume

Solve 2x – 11 = k for x.
Flura [38]

Answer:

First, you add 11 to the other side of the equals sign. So it would be 2x=k+11. Now, you divide 2 from x and do the same on the other side of the equals sign. so x=  k+11

F(x)=2x and g(x)=square root of x what is the domain of f(g(x))?
Dmitriy789 [7]

Answer:

x\ge 0

Step-by-step explanation:

The given functions are:

f(x)=2x


and


g(x)=\sqrt{x}


Now,

f(g(x))=f(\sqrt{x} )


f(g(x))=2\sqrt{x}

The domain refers to values of x for which f(g(x))=2\sqrt{x} is defined.


The  expression under the radical sign must not be negative.

The domain is

x\ge 0
