Answer:

$y=\frac{5}{8}x+20$

Step-by-step explanation:

I'll start by finding the slope of this line using the slope formula:

$\frac{70-20}{80-0}\\\frac{50}{80}\\\frac{5}{8}$

Just by looking at the graph I know that the y-intercept is 20, so now I can write the equation in slope-intercept form (y=mx+b):

$y=\frac{5}{8}x+20$

Estimate the value of \frac{\sqrt{2\pi }}{\sqrt{5}}

Butoxors [25]

Answer:

the exact answer is 1.98

if we rationalize denominator we get root 0f 10 times pi divided by 5

root of 10 is about 3.1 ( $\pi$ ) so we have $\frac{\pi ^{2} }{5}$ ≈ 9.6/5 = 1.92

Step-by-step explanation:

$\frac{\sqrt{2\pi }}{\sqrt{5}} * \frac{\sqrt{5 }}{\sqrt{5}}$ = $\frac{\sqrt{10} \pi }{5}$

There are three numbers a, b, c, where a > b and b >c. Describe the positions of the numbers on a number line.

AfilCa [17]

In maths, the “>” sign means “greater than”, or “bigger than.” If we say A > B, that means (in English) “A is bigger than B.”
So, if A > B and B > C:
A is bigger than B, and B is bigger than C.

So the smallest would be C, since both A and B are bigger. Next is B, and biggest is A.

That is the order they would be in a number line: C - B - A
