Check the picture below.

that's done just with the provided links, and I simply ran a line, so it'll be thereabouts, roughly between 13 and 14, depending on how you hang the line.

anyhow, if you have a TI(texas instruments) 89+ or higher, you can just provide the value pairs of the data and run a quadratic regression, or an exponential.

there are some online regression calculators as well.

How do i do this cause im STRESSING TO THE MAX RIGHT NOW
ra1l [238]

Step-by-step explanation:

Something to remember is that, if a negative number has a large number in it (9, 10 etc.) instead of a smaller number (2, 3, etc.) then the greater number is actually smaller, because it is farther down on a number line.

1.) First, take -√9, and take away the - sign for a moment. Pretend it isn't negative.

2.) Next, find the square root of 9. What times what equals 9? 3x3=9, so √9=3.

3.) Now, place the negative sign back. So, this is -3.

4.) Now, take -2³. When there is a small number next to a normal number, that means that you need to multiply the large number by the small one. So, in this case, do 2x3.

5.) 2x3=6.

6.) Now, add the negative sign back to it. so, -6.

7.) Remember that if a negative number has a larger number, then it is actually smaller, as it is farther down on the number line.

8.) So, we have -3 and -6. Of course, -3 is larger. therefore, -2³ is less than -√9, and the answer is A.

Can someone help me on the last question?
BabaBlast [244]

Answer:

I like saying rise over run because it helps me remember that rise means how many units you move up or down from point to point which on a graph would be a change in the y values. Also that run means how far left or right you move from point to point which on the graph would mean a change of x values.

What is the sequence rule for : 1.8, 2.58, 3.90, 4.95, 6
slamgirl [31]
I believe there is a typo in the problem. It should be:<span>1.8, 2.85, 3.90, 4.95, 6
If that was the case, the answer will be easy.

In this sequence, the rule is start at 1.80 then keep add 1.05. You can try to put them all into the equation

</span>1.80 + 1.05= 2.85
2.85+ 1.05= 3.90
3.90+ 1.05= 4.95
4.95+ 1.05= 6.00
