Answer:

Option A - \frac{2y^{4}}{x^4}

Step-by-step explanation:

Given : Expression \frac{14x^4y^6}{7x^8y^2}

To find : Which expression is equivalent to the given expression?

Solution :

Step 1 - Write the expression,

\frac{14x^4y^6}{7x^8y^2}

Step 2 - Apply exponent rule, \frac{x^a}{x^b}=x^{a-b}

=\frac{14}{7}x^{4-8}y^{6-2}

Step 3 - Solve,

=2x^{-4}y^{4}

=\frac{2y^{4}}{x^4}

So, \frac{14x^4y^6}{7x^8y^2}=\frac{2y^{4}}{x^4}

Therefore, Option A is correct.

Answer:

A. 2y^4 over x^2

Step-by-step explanation:

4x^4y^6 ÷ 7x^8y^2

First, you will find the GCF of the equation which is: 7x^4y^2 .

Then, you will divide both of the equation by the GCF which will become:

14x^4y^6 ÷ 7x^4y^2 = 2y^4

7x^8y^2 ÷ 7x^4y^2 = x^2

Hence, the final answer is 2y^4 over x^2

Find the volume of the cone.
frez [133]

Find the volume of a cone with a diameter of 20m and a slant height of 26m.

Volume Formula of a Cone: V = pi(radius^2)(h/3)

Diameter: 20m

Slant Height (Height): 26m

Plug it in:

V = 3.14(10^2)(26/3)

V = 314(26/3)

Solve:

V = 314(0.87)

V = 273.18

Volume = 273.18

Round:

Volume = 273m^3

The volume of the cone is 273m^3 to the nearest whole number.

Katena32 [7]

Let

A=B=\begin{bmatrix}0&1\\1&0\end{bmatrix}

Then

AB=BA=\begin{bmatrix}0&1\\1&0\end{bmatrix}^2=\begin{bmatrix}1&0\\0&1\end{bmatrix}

8. Peter and his partner are conducting a physics experiment on pendulum motion. Their 30-cm
katrin2010 [14]

Answer: 90/pi degrees

Step-by-step explanation:

It forms a 15cm arc from a circle of radius 30 cm.

The diameter is 30*2*pi = 60pi cm. So the arc is 15/60pi = 1/4pi of the way around a 360 degree circle. This is 1/4pi * 360 = 90/pi degrees.

Hope that helped,
