81 is not a perfect square nor a perfect cube, because 81 is an odd number so no matter how you stacked 81 cubes up you would still be missing one cube.

The volume of a cube is 64 cubic inches. Which expression represents s, the length of a side of the cube?
vlabodo [156]

Answer:

<h2>Therefore the length of a side of a cube is \sqrt[3]{64}\ or\ 4</h2>

Step-by-step explanation:

The volume of a cube is expressed as L³ where L is the length of each side of the cube.

Given volume of a cube = 64in³

On substituting;

64 = L³

Taking the cube root of both sides to determine L we have;

\sqrt[3]{64} = (\sqrt[3]{L})^{3}\\\sqrt[3]{64} = L\\L=4

Therefore the length of a side of a cube is \sqrt[3]{64}\ or\ 4

What is the measure of angle XYZ?
Ierofanga [76]

Answer:

63degrees

Step-by-step explanation:

Using the theorem which states that the measure of angle at the vertex is half the angle of its intercepted arc.

Given

angle of its intercepted arc = 126 degree

Required

angle at the vertex = x =<XYZ

According to the theorem;

x = 1/2(126)

x = 126/2

x = 63

Hence the measure of <XYZ is 63degrees

Consider the graph of the function f(x)=2x.
77julia77 [94]

Given:

The parent function is:

f(x)=2^x

The other function is:

g(x)=2f(x)

To find:

The statement that describes a key feature of function g.

Solution:

We have,

f(x)=2^x

g(x)=2f(x)

Using these two functions, we get

g(x)=2(2)^x

Putting x=0, we get

g(x)=2(2)^{(0)}

g(x)=2(1)

g(x)=2

The y-intercept of the function g at (0,2). So, option A is correct and option B is incorrect.

We know that g(x)\to 0 as x\to -\infty and it will never intersect the line y=0. It means the horizontal asymptote of the function g is

Therefore, the correct option is A.
