The points on a graph are frequently used to represent the relationships between two or more objects.

The filled out table exists as follows:

Row 1 = 2, 4, 8

Row 2 = 6, 36, 216

<h3>What is meant by graph?</h3>

A graph is a visual representation or diagram used in mathematics that displays data or values in an organized manner. The points on a graph are frequently used to represent the relationships between two or more objects.

In the first row we have x² = 4. Apply the square root to both sides to get x = 2. It appears your teacher is making x positive.

So we'll have 2 in the first box of row 1.

If x = 2, then x³ = 8 after cubing both sides.

In other words, x³ = 2³ = 2 × 2 × 2 = 8

The value 8 goes in the other box of row 1.

For row 2, we use x = 6 to square that to get x² = 6² = 6 × 6 = 36.

36 will go in the blank box for row 2.

The filled out table exists as follows:

Row 1 = 2, 4, 8

Row 2 = 6, 36, 216

Can some show the steps and the answer please I really need help tell me how you get it and the answer
Tems11 [23]

Answer:

Step-by-step explanation:

here is some helpful trig function reminders.. copy this and keep it

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

they ask how long is the ladder

they give us the opposite side (8) and the adjacent side (6)  

and the Hyp is the length of the ladder.   They expect you to sort this out in your head.  :/  

there is two steps .. we'll solve for the angle.. then we can use that to find the Hyp side..(long side of triangle)  which is the ladder length

Tan(Ф) = Opp / Adj

Tan(Ф) = 8 / 6

Ф = arcTan(8 / 6)

Ф ≈ 53.130°

now lets use that angle with one of the other trig functions to find the Hyp.. sin or cos will work b/c we have both the opp and the adj sides lengths.  let's use cos

Cos(53.130) = 6 / Hyp

Hyp = 6 / Cos(53.130)   ( I just used algebra to swap the two)

Hyp = 9.99997

the ladder will be 10' long.  

ask in the comments if you need any more explaining

Stats To quality for a police academy, applicants are given a lest of physical Itness. Ihe scores are normallyDistributed with a
omeli [17]

Since we want just the top 20% applicants and the data is normally distributed, we can use a z-score table to check the z-score that gives this percentage.

The z-score table usually shows the percentage for the values below a certain z-score, but since the whole distribution accounts to 100%, we can do the following.

We want a z* such that:

P(z>z^*)=0.20

But, to use a value that is in a z-score table, we do the following:

\begin{gathered} P(zz^*)=1 \\ P(zz^*)=1-0.20=0.80 \end{gathered}

So, we want a z-score that give a percentage of 80% for the value below it.

Using the z-score table or a z-score calculator, we can see that:

\begin{gathered} P(zNow that we have the z-score cutoff, we can convert it to the score cutoff by using:[tex]z=\frac{x-\mu}{\sigma}\Longrightarrow x=z\sigma+\mu

Where z is the z-score we have, μ is the mean and σ is the standard deviation, so:

\begin{gathered} x=0.8416\cdot9+64 \\ x=7.5744.64 \\ x=71.5744\cong72 \end{gathered}

so, the cutoff score is approximately 72.

Solve x <br><br> 4x-5 /5 = 3
cluponka [151]

Answer:

x = 1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4x−

5

5

=3

4x+−1=3

4x−1=3

Step 2: Add 1 to both sides.

4x−1+1=3+1

4x=4

Step 3: Divide both sides by 4.

4x

4

=
