the volume is 20 you have to add the inches i graphed it and the units were 20 so the volume of the cone 20

The formula for the volume of a cone is V = PI x r^2 x h/3

r = 1/2 the diameter. 1/2 of 8 = 4 inches.

h = height = 12 inches.

Using 3.14 for PI, the formula now becomes:

V = 3.14 x 4^2 x 12/3

V = 3.14 x 16 x 4

V = 200.96 cubic inches.


You do not say if the answer needs to be rounded, so round the answer as needed.

Find the product of (–d + e)(4e + d). Which statements are true? Check all that apply.
Bogdan [553]

Hello!

This is a question about multiplying to get a polynomial answer.

Here we can use two strategies, which will get you the same strategy.

One is using a Punnett Square, and the other would be FOILing.

I personally like Punnett Squares, but I will use FOILing for the sake of being online.

FOIL stands for First, Outside, Inside, Last, which describes how the terms should be multiplied.

Let's multiply the first terms.

(-d + e)(4e + d)

-4de

The outside terms.

(-d + e)(4e + d)

-d^2

The inside terms.

(-d + e)(4e + d)

4e^2

The last terms.

(-d + e)(4e + d)

de

Now you just add them together to find the polynomial.

-d^2+4e^2-4de+de

-d^2+4e^2-3de

There are three terms in the product, and the product is degree 2, since the highest degree of the equation (the highest power any term is raised to) is 2.

Hope this helps!

Which of the following shows the true solution to the logarithmic equation 3 log Subscript 2 Baseline (2 x) = 3
VARVARA [1.3K]

Answer:

x = 1

Step-by-step explanation:

We have to solve the given logarithmic equation of variable x.

The equation is 3\log _{2} (2x) = 3

⇒ \log_{2} (2x)^{3} = 3  

{Since, we know the logarithmic property, a \log b = \log b^{a}}

⇒ \log_{2} (2x)^{3} = 3\log_{2}2 = \log_{2} 2^{3}

{Since we know that \log_{a} a = 1}

Now cancelling log from both sides we get,  

(2x)^{3} = 2^{3}

⇒ x^{3} = 1

⇒ x = 1 (Answer)
