5√5 can be written in the form [tex]5^{k}[/tex]

Find the value of k

### Answers

**Answer:**

n=3/2

**Step-by-step explanation:**

5 = 5^(1/2)

5√5 = [5^1] * [5^(1/2)]

when you multiply you add exponents

5√5 = 5^(1 + 1/2)

but 1 = 2/2

so

5√5 = 5^[(2/2) + (1/2)] = 5^[3/2]

Reed is currently r years old. Which expression represents his age seven years from now

### Answers

**Answer: r+7**

Whatever his age is now, we add 7 to it. So we simply add 7 to r getting r+7.

Example: Say he is 10 years old now

r = 10

**r+7** = 10+7 = 17

meaning he will be 17 seven years from now

### Answers

**Answer:**

m∠5 = 67

m∠7 = 67

**Step-by-step explanation:**

m∠4 and m∠5 add up to 180 because they are same side interior angles.

180 - 113 = m∠5

m∠5 = 67

m∠5 = m∠7 because they are vertically opposite angles

hence, m∠7 = 67 degrees

**Answer:**

angle 5: 67 degrees. Angle 7: 67 degrees. (make sure to add the degrees logo)

**Step-by-step explanation:**

basically, angle 4 is 113 degrees. 180 degrees minus 113 is 67, which is how much angles 1 and 3 are. angles one and three are also equivalent to 5 and 7, which means they are also 67 degrees

Solve for x.

3x^2-14=13

### Answers

**Answer:**

x = ± 3

**Step-by-step explanation:**

Given

3x² - 14 = 13 ( add 14 to both sides )

3x² = 27 ( divide both sides by 3 )

x² = 9 ( take the square root of both sides )

x = ± [tex]\sqrt{9}[/tex] = ± 3

I got it right on edge

The describes a **prediction **for the **end** **behavior **of the graph of f(x) is

∞, f(x) - ∞ and x- (-∞), f(x) - ∞.

What is End Behavior of function?

The **behaviour **of the function graph at the "**ends**" of the x-**axis **is known as the end behaviour of a function, or f.

In other words, if we look at the **right end **of the x-axis (as x approaches + ∞) and the left end of the x-axis (as x approaches -∞), the end behavior of a function represents the trend of the graph.

We have,

the table as

x -5 -4 -3 -2 -1 0 1 2 3

f(x) 14 6 0 -4 -6 -6 -3 0 6

If we look at the **table **then we can conclude for further values

x **tends **to ∞ then f(x) tends to ∞

and, when x **tends **to -∞ then f(x) tends to ∞.

1. 3x^2 - 4x = 0

### Answers

**Step-by-step explanation:**

By solving, I am assuming that you want to find the zeros.

So to find what x equals, first, you factor out an x.

3x² - 4x = 0

x(3x - 4) = 0

Here, you can separate the equation into two different equations to solve for x.

*3x - 4 = 0* and *x = 0*3x = 4x = [tex]\frac{4}{3}[/tex] and x = 0

Those are your zeros.

And for its graph, you can always look to an online graphing calculator. I used Desmos.

B well tip is 10% so do 15 times 10 + 15 and that will be your answer for b

**Answer: **

**.99**

**18.99**

**Step-by-step explanation:**

The answer to the first one is o.99 bc you would change 6.6% to a decimal and that would be 0.066 then you would add one to it and multiply it by 15 so the equation would look like this 1.066*15=0.99

The answer to the second one is 18.99 bc you would add 20% to 6.6% to get 26.6% and then you would change that into a decimal and add one to it to get 1.266 then multiply it by 15 to get 18.99

Point K is on line segment \overline{JL} JL . Given JK=5x+7,JK=5x+7, JL=2x+8,JL=2x+8, and KL=4,KL=4, determine the numerical length of \overline{JL}. JL .

### Answers

**Answer:**

JL = 6 units

**Step-by-step explanation:**

It is given that,

K lies on line segment JL.

We have, JK=5x+7,JL=2x+8, and KL=4.

JL = JK + KL

2x+8 = 5x+7 + 4

Taking like terms together.

8-7-4=5x-2x

-3 = 3x

**x = -1**

Put x = -1 in JL = 2x+8. So,

JL = 2(-1)+8

JL = 6

**Hence, the length of JL is 6 units.**
