Answer:

y = 1/2x - 1

Step-by-step explanation:

Alright

Let's find the slope first:

-12+14/-18+22

2/4 = 1/2

So this is what it's increasing by each time. Now we find the y-intercept.

I used Desmos to find it, because graphing for visualization is great for these kinds of things.

The y-intercept I got was -1.

So the full equation would be: y= 1/2x -1

Determine the common ratio and find the next three terms of the geometric sequence 9,3sqrt3,3

Maru [420]

Answer:

Fourth term: $a_4 = 9 * (\frac{\sqrt{3}}{3})^{(4 - 1)}$ = $9 * (\frac{\sqrt{3}}{3})^{3}$ = $\sqrt{3}$

Fifth term: $a_5 = 9 * (\frac{\sqrt{3}}{3})^{(5 - 1)}$ = $9 * (\frac{\sqrt{3}}{3})^{4}$ = 1

Sixth term: $a_6 = 9 * (\frac{\sqrt{3}}{3})^{(6 - 1)} = 9 * (\frac{\sqrt{3}}{3})^{5} =\frac{\sqrt{3}}{3}$

Step-by-step explanation:

The geometric progression is:

$9, 3 \sqrt{3}, 3...$

The first term, a, is 9

To find the common ratio, r, all we have to do is divide a term by its preceding term.

Let us divide the second term by the first:

$r = \frac{3\sqrt{3}}{9}\\ \\r = \frac{\sqrt{3}}{3}$

That is the common ratio.

Geometric progression is given generally as:

$a_n = ar^{(n - 1)}$

where a = first term

r = common ratio

$a_n$ = nth term

We need to find the 4th, 5th and 6th terms.

Fourth term: $a_4 = 9 * (\frac{\sqrt{3}}{3})^{(4 - 1)}$ = $9 * (\frac{\sqrt{3}}{3})^{3}$ = $\sqrt{3}$

Fifth term: $a_5 = 9 * (\frac{\sqrt{3}}{3})^{(5 - 1)}$ = $9 * (\frac{\sqrt{3}}{3})^{4}$ = 1

Sixth term: $a_6 = 9 * (\frac{\sqrt{3}}{3})^{(6 - 1)} = 9 * (\frac{\sqrt{3}}{3})^{5} =\frac{\sqrt{3}}{3}$

Meghan's dog spray eats 4 ¹/4 cups of food each day. Explain how megan can determine how much food to give sparky if she needs t

Alexxandr [17]

Answer:

$\frac{17}{6}\ cups$

Step-by-step explanation:

$Total\ required\ food\ for\ sparky=4\frac{1}{4}\ cups\\\\Total\ required\ food\ for\ sparky=\frac{17}{4}\ cups\\\\Megan\ needs\ to\ feed\ him\ only\ \frac{2}{3}\ as\ much\\\\Food\ given\ by\ Megan=\frac{2}{3}\times Total\ required\ food\ for\ sparky\\\\Food\ given\ by\ Megan=\frac{2}{3}\times \frac{17}{4}\\\\Food\ given\ by\ Megan=\frac{17}{6}\ cups$
