The cube root is the same as the 1/3 exponent.  In general an exponent of 1/n is an nth root.

Answer:

Here is a note to help you: Most numbers are rational numbers. Here is how you know when a number is rational or not [especially if its a decimal].

Rational:

- Decimals are usually rational. Rational decimals my look like this:

1) 0.25

2) 0.333333333...

3) 0.234234234234234234...

The following above are rational because they either: terminate or repeat. That being said, 1) terminates, and 2) and 3) repeat because the pattern of 2) is just 3's, and the pattern of 3) is 0.234 over and over again.

Irrational:

- Irrational numbers are numbers that don't repeat, and don't terminate. The next examples are irrational:

1) 0.234536718092343...

2) 8.123456789023452574794832468...

3) 1723456.4356784794954233690422...

- They go on forever and ever, and don't have a pattern/terminate like rational numbers.

Now that you've got that in the bag, its time for your answers!

Step-by-step explanation:

A) rational --> It has a pattern, but does not terminate

B) rational --> It terminates

C) irrational --> it does not have a pattern, even if it does terminate

D) rational --> when you solve it, the answer is 2, and 2 is rational

E) irrational --> it does not have a pattern, but does terminate

I hope I helped you! This took forever, but it was worth it! :D

Create the f(x) function based on the table. Your answer should be in function notation. X f(x) - 10 -6 -9 -5 1-8 -4 -7 1-3 5 9​
Minchanka [31]

Answer:

f(x) = x + 4

Step-by-step explanation:

First create an equation in slope-intercept form, y = mx + b. To do this, find the rate of change or slope (m), and the y-intercept (b).

Using two pairs, (-7, -3) and (-8, -4),

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-4 -(-3)}{-8 -(-7)} = \frac{-1}{-1} = 1

m = 1

To find b, substitute m = 1, x = -7 and y = -3 into y = mx + b.

Thus:

-3 = (1)(-7) + b

-3 = -7 + b

-3 + 7 = b

4 = b

b = 4.

Replace y with f(x), m with 1 and b with 4 in y = mx + b.

The function would be:

f(x) = x + 4

Create an equation in slope-intercept form from A line that includes the point (6,–7) and has a slope of 2.
Svet_ta [14]

Answer:

<em>Use </em><em>the </em><em>equation</em><em> </em><em>y=</em><em>mx+</em><em>c</em>

<em>the </em><em>slope(</em><em>m)</em><em> </em><em>is </em><em>2</em><em>,</em><em>y </em><em>is </em><em>-7and </em><em>x </em><em>is </em><em>6</em>

<em>therefore</em><em> </em><em>you </em><em>firstly</em><em> </em><em>have </em><em>to </em><em>find </em><em>the </em><em>y </em><em>intercept</em><em> (</em><em>c)</em>

<em>y=</em><em>mx+</em><em>c</em>

<em>-</em><em>7</em><em>=</em><em>2</em><em>(</em><em>6</em><em>)</em><em>+</em><em>c</em>

<em>-</em><em>7</em><em>=</em><em>1</em><em>2</em><em>+</em><em>c</em>

<em>-</em><em>7</em><em>-</em><em>1</em><em>2</em><em>=</em><em>c</em>

<em>-</em><em>1</em><em>9</em><em>=</em><em>c</em>

<em>then </em><em>replace </em><em>the </em><em>gradient</em><em> </em><em>and </em><em>y </em><em>intercept</em><em> </em><em>in </em><em>the </em><em>equation</em>

<em>y=</em><em>mx+</em><em>c</em>

<em>y=</em><em>2</em><em>x</em><em>-</em><em>1</em><em>9</em>

<em>or </em><em>you </em><em>can </em><em>use </em><em>the </em><em>formula</em><em> </em><em>y-y1=</em><em> </em><em>m(</em><em> </em><em>x-x1)</em>

<em>I </em><em>hope </em><em>this </em><em>helps</em>
