Hi there!

Let's start by looking at our like terms:
12 and 7
2v and 7v
13v^3 and 13v^3

Since all of those terms are like each other, they can be added together. The terms that are being cubed can only be added to other terms being cubed because otherwise things would be a bit messed up. Here's what we can add together:
12 + 7 = 19
2v + 7v = 9v
13v^3 + 13v^3 = 26v^3

Now, we need to organize the terms in the expression like this - variable and cubed, just a variable, number. Using that our expression ends up being:
26v^3 + 9v + 19

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

(12 + 2v + 13v^3) + (13v^3 + 7 + 7v)
12 + 2v + 13v^3 + 13v^3 + 7 + 7v - drop the parenthesis since adding
13v^3 + 13v^3 + 7v + 2v + 12 + 7 - Group by like terms
26v^3 + 9v + 19 - combine like terms

which of the following best describes a regular polygon when the measure of each exterior angle is 36 ?

zhenek [66]

<span>Even though you have no choices listed:

Each Exterior Angle = Each Central Angle = (360 degrees) ÷ (Number of Sides)
</span>Each Exterior Angle = <span>(360 degrees) ÷ (Number of Sides)
</span><span>(Number of Sides) = 360 / 36
</span><span>Number of Sides = 10
a 10-sided polygon is a decagon

Write an equation in point slope and slope intercept form of a line that passes through the given point and has the given slope

Evgesh-ka [11]

Answer:

Point-Slope: $y+4=-\frac{1}{2}(x+3)$

Slope-Intercept: $y=-\frac{1}{2}x-\frac{11}{2}$

Step-by-step explanation:

The point-slope formula is $y-y_{1}=m(x-x_{1} )$ . The slope-intercept formula is $y=mx+b$ . Since we are given the point and slope, we can directly plug it into the point-slope formula.

Point-Slope

$y-(-4)=-\frac{1}{2}(x- (-3))$

$y+4=-\frac{1}{2} (x+3)$

To find the slope-intercept form, we can manipulate the point-slope form to get the slope-intercept form.

Slope-Intercept

$y+4=-\frac{1}{2}x-\frac{3}{2}$

$y=-\frac{1}{2}x-\frac{11}{2}$

Let an denote the nth term of a geometric sequence. let a0=256 and an+1=0.5an .

dusya [7]

The explicit formula is $a_{n-1} = 256 * 0.5^{n-1$ and the sum of the first 25 terms is approximately 512

<h3>The explicit formula</h3>

The given parameters are:

$a_0 = 256$

$a_{n +1} = 0.5a_n$

Set n = 0

$a_1 = 0.5a_0$

Substitute 256 for a0

$a_1 = 0.5 * 256$

$a_1 = 128$

This means that the common ratio is 0.5.

The explicit formula is then represented as:

$a_{n-1} = a_0 * r^{n-1$

This gives

$a_{n-1} = 256 * 0.5^{n-1$

<h3>The sum of the first 25 terms</h3>

This is calculated using:

$S_n = \frac{a_0(r^{n-1} -1)}{r - 1}$

This gives

$S_{25} = \frac{256 * (0.5^{25-1} -1)}{0.5 - 1}$

Evaluate

$S_{25} = 512$

Hence, the sum of the first 25 terms is approximately 512

The volume of a cube can be found using the equation V = s³, where V is the volume and s is the measure of one side of the cube.

Marina86 [1]

Answer:

side measure = 9 in

Step-by-step explanation:

volume of a cube: $V=s^3$

where V is the volume and s is one side of the cube

Given volume = 729 in³

$\implies s^3=729$

$\implies s=\sqrt[3]{729}$

$\implies s=9 \ \textsf{in}$

A line passes through the (1, -6) and has a slope of 5. write an equation for this line

o-na [289]

The point-slope form of the equation for a line with slope m through point (h, k) is ...
y = m(x -h) +k

Your line's equation can be written as
y = 5(x -1) -6

This can be simplified to slope-intercept form
y = 5x -11
or standard form
5x -y = 11
