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)
option 1

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 :)

Resolving a function of any nature means determining your zeros or raizes.

The zeros of a function occur when the function is null.

Then:

f(x) = 3x - 2

To determine the root
f(x) = 0 = 3x - 2
3x = 2
x = 2/3 Final result

Find the height in centimeters of a square pyramid with a volume of 455cm3 and a base edge length equal to the height. Give the

Ulleksa [173]

Answer:

<em></em> $h = 7.69cm$ <em></em>

<em></em>

Step-by-step explanation:

Given

$Volume = 455cm^3$

$l = h$

Where:

$h \to height$

$l \to base\ length$

Required

The height

The volume is calculated as:

$Volume = l^2 * h$

This gives:

$Volume = h^2 * h$

$Volume = h^3$

Rewrite as:

$h^3 =Volume$

So, we have:

$h^3 = 455cm^3$

Take cube roots

$h = \sqrt[3]{455cm^3}$

<em></em> $h = 7.69cm$ <em> --- approximated</em>

Write an equation of the line in slope-intercept form.

Pachacha [2.7K]

Answer:

y = 2x+3

Step-by-step explanation:

You can see that the line crosses the y-axis at (0,3), so the y-intercept is 3.

To find the slope, compare the coordinates of the two points marked on the line, (0,3) and (-3,-3).

slope = Δy/Δx = ((-3)-3)/((-3)-0) = (-6)/(-3) = 2

Slope-intercept equation for line of slope 2 and y-intercept 3:

y = 2x+3

The standard deviation for a set of data with mean 25 and variance 16 is?

svet-max [94.6K]

Answer:

Standard deviation = 4

Step-by-step explanation:

Given the following data;

Mean = 25

Variance = 16

To find the standard deviation;

Mathematically, standard deviation is given by the formula;

$Standard \; deviation = \sqrt{variance}$

Substituting into the formula, we have;

$Standard \; deviation = \sqrt{16}$

Standard deviation = 4
