Answer:

Hello! I wanted to explain the answer which someone might have already answered.. First off, I want to let you know that the Answer is "The scatter plot shows a linear association." But how? Well, linear means: "arranged in or extending along a straight or nearly straight line." Which if you didn't notice.. All the points on the graph, make up a generally straight line.

"No association" means there is no line or association with any of the points. So, you'd pick that if the points were all over the graph in no order, line or combination; which isn't the case.

Step-by-step explanation:

Find the sum.<br> 14 + 42 + 70 + ... + (28n − 14)

lions [1.4K]

Answer:

14n^2.

Step-by-step explanation:

This is Arithmetic with first term a = 14 and common difference d = 28.

Sum of n terms = n/2[2a + (n-1)d]

= n/2(28 +( n -1)28]

= n/2(28 + 28n - 28)

= 14n^2

(-18x^2+12x-2)*(x^3+12x^2+48x+64)

prohojiy [21]

<h2>Answer:</h2>

-18x^5-204x^4-722x^3-600x^2+672x-128

<h2>Explanation:</h2>

$( - 18 {x}^{2} + 12x - 2)$

$( {x}^{3} + 12 {x}^{2} + 48x + 64)$

There are multiple ways to solve this for example the foil method or the box method. I prefer to do the box method.

First we are going to set it up

After we set it up we have to solve it so first we are going to multiply

${x}^{3} \times - 18 {x}^{2} = - 18 {x}^{5}$

We have to add the exponent

$- 18 {x}^{2} \times 12 {x}^{2} = - 216 {x}^{4}$

$- 18 {x}^{2} \times 48x = - 864 {x}^{3 } \\ - 18{x}^{2} \times 64 = - 1152 {x}^{2} \\ 12x \times {x}^{3} = 12 {x}^{4} \\ 12x \times 12 {x}^{2} = 144 {x}^{3}$

$12x \times 48x = 576 {x}^{2} \\ 12x \times 64 = 768x$

$- 2 \times {x}^{3} = - 2 {x}^{3} \\ - 2 \times 12 {x}^{2} = - 24 {x}^{2} \\ - 2 \times 48x = - 96x \\ - 2 \times 64 = - 128$

Now we have to add them

-18x^5 stays because there is nothing to add to

Now we add the rest

$-216 {x}^{4} + 12 {x}^{4} = - 204 {x}^{4}$

$- 864 {x}^{3} + 144 {x}^{3} + - 2 {x}^{3} = - 722 {x}^{3}$

$768x - 96x = 672x$

And -128 stays the same

$- 1152 {x}^{2} + 576 {x}^{2} - 24 {x}^{2} = - 600 {x}^{2}$

The answer is

-18x^5-204x^4-722x^3-600x^2+672x-128

an unopened can of iced tea contains 350 cubic centimeters of liquid. if the van is 5 inches long and has a .8 inch diameter, wh

MariettaO [177]

the can is 5 inches tall, so its height is 5 inches, so 3 inches off 5 inches that'd be 3/5.

the can has a diameter of 0.8 inches, meaning it has a radius of half that, or 0.4 inches.

if say the volume of iced-tea is V, how much is 3/5 of V? well, is just their product.

$\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=0.4\\ h=5 \end{cases}\implies V=\pi (0.4)^2(5)\implies V=0.8\pi \\\\\\ \stackrel{\textit{and 3/5 of that will be}}{\cfrac{3}{5}\cdot 0.8\pi }\implies V\approx \stackrel{in^3}{1.51}$
