Which equation represents a geometric sequence?

1 answer:

3 0

I think the answer is A, but I could be wrong. I think the answer is A, because it is the only equation that is linear. In mathematics a geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number, meaning when you graph it the line should be linear. Of all of these A is the only that is Linear the others are not. The slope of line A is 2 and the Y-intercept is 3.

If 90 is 80% of a value, what is that value?

Anna71 [15]

So 90 is 4/5 of a number.

4/5n=90

4n=450

n=450/4

n=112.5

Answer:

$\sf \bold 9\sqrt{2}$

Step-by-step explanation:

<h3>Simplifying radicals</h3>

Step1: Prime fatorize and reduce to simplest form

Step2: Combine like radicals

$\sf 3\sqrt{2} - 2\sqrt{18}+6\sqrt{8}= 3\sqrt{2}- 2\sqrt{3*3*2}+6\sqrt{2*2*2}$

$\sf = 3\sqrt{2}-2*3\sqrt{2} +6*2\sqrt{2}\\\\=3\sqrt{2}-6\sqrt{2}+12\sqrt{2}\\\\=(3-6+12)\sqrt{2}\\\\ = 9\sqrt{2}$

Find an equation of the line containing the points (-5,7) and (-5,8). Express your answer in slope intercept form.

alexdok [17]

Try, pls, this:
1. Note, that for the both points x₁=x₂=-5, it means line is vertical, that is equation form is x=a, where a=number.
2. The number for 'a' may be extracted from points, a=-5.
3. Equation for line is x=-5.
