First we rewrite the expression:
 (4x ^ 3) * (2x) ^ - 4
 Using properties of exponents we have:
 (4x ^ 3) / (2x) ^ 4
 Rewriting:
 (4x ^ 3) / 16x ^ 4
 (x ^ 3) / 4x ^ 4
 (1) / (4x)
 answer:
 An equivalent expression is:
 (1) / (4x)

Answer:
1 / 4x

Explanation:
(4x^3) * (2x)^-4 = 4x^3 * 2^-4 * x^-4
                         = (4x^3) / (2^4 * x^4)
                         = (1/4) * (1/x)
                         = 1 / 4x

Hope this helps :)

What is the difference between experimental and nonexperimental methods of study? Nonexperimental methods involve operational de
Anon25 [30]

Experimental methods involve the manipulation and control of variables, whereas non experimental methods require simple observation of the variables.

Answer: Option D.

<u>Explanation:</u>

Non-experimental research about doesn't mean nonscientific. Non-experimental investigate implies there is an indicator variable or gathering of subjects that can't be controlled by the experimenter. Test plan, then again, takes into consideration specialists to control the indicator variable and subjects.

Non experimental research falls into three broad categories: single-variable research, correlational and quasi-experimental research, and qualitative research.

What is the vertex of the quadratic function f(x) = (x - 3)(x - 2)?<br> D
Lera25 [3.4K]

Answer:

Step-by-step explanation:

Get the equation in the form y = ax2 + bx + c.

Calculate -b / 2a. This is the x-coordinate of the vertex.

To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y.

- that's how you find the vertex of the quadratic function-

Find the equation of the line in slope-intercept form containing the two points: (−1,5) and )(4,−3) Leave equation in fractional
lilavasa [31]

Answer:

y = 1.6x + 3.4

Step-by-step explanation:

We have to use the equation y = m x + c to find the equation of the line.

Here,

m ⇒ slope

c ⇒ y-intercept

<u>First, let us find the slope.</u>

For that, we can use the given two coordinates.

( -1 , 5 ) ⇒ ( x₁ , y₁ )

( 4 , -3 )  ⇒ ( x₂ , y₂ )

The <u>formula to find the slope</u> of a line is :

m = ( y₁ - y₂ ) ÷ ( x₁ - x₂ )

<u>Let us solve now.</u>

m = ( y₁ - y₂ ) ÷ ( x₁ - x₂ )

m = ( 5 - ( -3 ) ) ÷ ( -1 - 4 )

m = ( 5 + 3 ) ÷ -5

m = 8 ÷ -5

<u>m = -1.6</u>

Now let us<u> find the y-intercept (c )</u> of the line.

For that, let us get one of the coordinates which are given in the question.

I'll get ( -1 , 5 ) from  that.

( -1 , 5 ) ⇒ ( x , y )

<u>Let us solve now.</u>

y = mx + c

5 = -1.6 × -1 + c

5 = 1.6 + c

5 - 1.6 = c

<u>3.4 = c</u>

Therefore,

m ⇒ -1.6

c ⇒ 3.4

So, the equation of the line is :

y = mx + c

<u>y = 1.6x + 3.4</u>
