When finding the volume of this shape, there would practically be a formula that we would have to use, in order to solve this on how we are suppose to do.

We know that the radius would then be 4, and therefore, we would just plug this in into the formula which would be illustrated below.

$\boxed{V= \frac{4}{3} \pi r^3}$

All we would have to do, is to plug the number 4 into the proper location in the formula.

In a decimal form, your correct answer would then be 268.08.

By as we can see above, we would have to convert the decimal form, into a fraction form, and this would be shown below.

$\left[\begin{array}{ccc}\boxed{3*8=24-8=256/3}\end{array}\right]$

Your correct answer should be (option a)

Can someone help me understand how to do this quadratic math problem

Answer:

put all of the expressions into the same form, such as standard form

Step-by-step explanation:

When you're trying to determine whether one expression is equivalent to another, you need to put both of the expressions into the same form. This will generally require some algebraic manipulation using the rules of equality.

Here, you're given a quadratic in standard form. From what we can see of the one partial answer, some of the choices are in vertex form. To determine if they are equivalent, you can do either of two things ...

Put the given expression into vertex form
Expand the answer choice to put it in standard form

___

<em>For multiple-choice questions</em> of this type, it is often sufficient to look at one or two terms of the different equations. That is usually all it takes to separate a good answer from a bad one.

You can start with the x^2 term. Any answer choice that has an x^2 coefficient different from 1 will be rejected.

Next, you can look at the sign of the x term. Any answer choice that doesn't have a positive x term will be rejected.

Finally, you can look a the constant term. Any answer choice that doesn't have a constant term of +4 will be rejected.

___

As it happens, the given equation is a perfect square, so one equivalent is ...

y = (x +2)^2

_____

When working with quadratics, it can be helpful to memorize a couple of the ways they can be written:

(x +b)^2 = (x^2 +2bx + b^2)

This is a special case of ...

(x +a)(x +b) = x^2 +(a+b)x + ab

Which graph represents f(x)=log3x 1?

exis [7]

The correct option A: graph A, shows the logarithmic function;

f(x) = log₃x + 1

<h3>Explain the term logarithmic function?</h3>

The opposite of such an exponential function is a logarithmic function.
A log function and then an exponential function both use the same base.
An exponent is a logarithm. f(x) = bx is how the exponential function be expressed.
The formula again for logarithmic function is f(x) = log base b of x.

f(x) = log₃x + 1
