help please and thankyou

Answer:0.6

Step-by-step explanation:

We can grab 2 points in this table and plug this into the slope formula: (y2-y1)/(x1-x2). The 2 easiest points would be (0,0) and (2, 1.2). Doing this would get us (1.2-0)/(2-0). Simplifying this would get us 1.2/2, or .6.

Starting with the 0th term the first 4 terms, would be 0, 1, 2, 3

Replace x with each term number and solve:

The answers are: 2, 10, 50, 250

Answer:

Let B = the weight of box B

Let 2B = the weight of box A

Let 2B + 30 = the weight of box C

B + 2B + 2B + 30 = 640

5B = 610

B = 122 pounds, weight of box B

2B = 2(122) = 244 pounds, weight of box A

2B + 30 = 2(122) + 30 = 274 pounds, weight of box C

Answer:

x=3

x=8

Step-by-step explanation:

The "Zero Product Property" says:

If  (x−3)(x−8) = 0  then   (x−3) = 0   or   (x−8) = 0

Now we just solve each of those:

For (x−3) = 0 we get x = 3

For (x−8) = 0 we get x = 8

And the solutions are:

x = 3, or x = 8

================================================

Work Shown:

x = some natural number

G = GCF(x,36)

L = LCM(x,36)

We can tie together the LCM and GCF like so

L = (x*36)/G

L = (x*36)/9

L = (36/9)*x

L = 4x

Whatever the value of x is, the LCM is 4 times larger.

Since we're told the LCM is 108, we can then say,

L = 108

4x = 108

x = 108/4

x = 27

--------------

Check:

GCF(x,36) = GCF(27,36) = 9, since 36 = 9*4 and 27 = 9*3, indicating that 9 is the largest shared factor

LCM(x,36) = LCM(27,36) = 108

LCM(x,36) = (x*36)/GCF = (x*36)/9 = (27*36)/9 = 972/9 = 108

This confirms we have the right answer.

Answer:

[tex]A\left(BC\right)=\begin{pmatrix}7&13\\ \:15&29\end{pmatrix}[/tex]

[tex]\left(AB\right)C=\begin{pmatrix}7&13\\ \:15&29\end{pmatrix}[/tex]

Therefore, we conclude that

[tex]A(BC)=(AB)C[/tex]

Step-by-step explanation:

Given that the associative law of matrix multiplication​

[tex]A(BC)=(AB)C[/tex]

Let

[tex]A=\begin{pmatrix}1&2\\ 3&4\end{pmatrix}[/tex]

[tex]B\:=\:\begin{pmatrix}1&0\\ 1&2\end{pmatrix}[/tex]

[tex]C=\begin{pmatrix}1&3\\ \:1&1\end{pmatrix}[/tex]

proving

A(BC)=(AB)C

Determining the L.H.S

[tex]A\left(BC\right)=\begin{pmatrix}1&2\\ \:\:3&4\end{pmatrix}\:\left[\:\begin{pmatrix}1&0\\ \:\:\:1&2\end{pmatrix}\begin{pmatrix}1&3\\ \:\:\:\:1&1\end{pmatrix}\right]\:[/tex]

First determining BC

as multiplying the rows of the first matrix by the column of the second matrix

[tex]BC=\begin{pmatrix}1&0\\ \:1&2\end{pmatrix}\begin{pmatrix}1&3\\ \:1&1\end{pmatrix}=\begin{pmatrix}1\cdot \:\:1+0\cdot \:\:1&1\cdot \:\:3+0\cdot \:\:1\\ \:1\cdot \:\:1+2\cdot \:\:1&1\cdot \:\:3+2\cdot \:\:1\end{pmatrix}[/tex]

       [tex]=\begin{pmatrix}1&3\\ 3&5\end{pmatrix}[/tex]      

so the matrix equation becomes

[tex]A\left(BC\right)=\begin{pmatrix}1&2\\ \:\:3&4\end{pmatrix}\begin{pmatrix}1&3\\ \:3&5\end{pmatrix}[/tex]

            [tex]=\begin{pmatrix}1\cdot \:1+2\cdot \:3&1\cdot \:3+2\cdot \:5\\ 3\cdot \:1+4\cdot \:3&3\cdot \:3+4\cdot \:5\end{pmatrix}[/tex]

            [tex]=\begin{pmatrix}7&13\\ 15&29\end{pmatrix}[/tex]

[tex]A\left(BC\right)=\begin{pmatrix}7&13\\ \:15&29\end{pmatrix}[/tex]

Determining the R.H.S

[tex]\left(AB\right)C=\left[\begin{pmatrix}1&2\\ \:\:\:\:3&4\end{pmatrix}\:\begin{pmatrix}1&0\\ \:1&2\end{pmatrix}\right]\begin{pmatrix}1&3\\ \:\:\:\:\:1&1\end{pmatrix}\:[/tex]

First determining AB

as multiplying the rows of the first matrix by the column of the second matrix

[tex]AB=\begin{pmatrix}1&2\\ \:\:3&4\end{pmatrix}\begin{pmatrix}1&0\\ \:\:1&2\end{pmatrix}=\begin{pmatrix}1\cdot \:\:1+2\cdot \:\:1&1\cdot \:\:0+2\cdot \:\:2\\ \:3\cdot \:\:1+4\cdot \:\:1&3\cdot \:\:0+4\cdot \:\:2\end{pmatrix}[/tex]

                                       [tex]=\begin{pmatrix}3&4\\ 7&8\end{pmatrix}[/tex]

so the matrix equation becomes

[tex]AB\left(C\right)=\begin{pmatrix}3&4\\ \:\:7&8\end{pmatrix}\begin{pmatrix}1&3\\ \:\:1&1\end{pmatrix}[/tex]

multiplying the rows of the first matrix by the column of the second matrix

            [tex]=\begin{pmatrix}3\cdot \:1+4\cdot \:1&3\cdot \:3+4\cdot \:1\\ 7\cdot \:1+8\cdot \:1&7\cdot \:3+8\cdot \:1\end{pmatrix}[/tex]

            [tex]=\begin{pmatrix}7&13\\ 15&29\end{pmatrix}[/tex]

Thus,

[tex]\left(AB\right)C=\begin{pmatrix}7&13\\ \:15&29\end{pmatrix}[/tex]

as

[tex]A\left(BC\right)=\begin{pmatrix}7&13\\ \:15&29\end{pmatrix}[/tex]

[tex]\left(AB\right)C=\begin{pmatrix}7&13\\ \:15&29\end{pmatrix}[/tex]

Therefore, we conclude that

[tex]A(BC)=(AB)C[/tex]

Answer:

Fiona earns $2/hour more than Philip.

Step-by-step explanation:

y = 12x shows a slope of 12. That slope is the hourly salary.

Philip earns $12/hour.

Fiona:

$42/(3 hours) = $14/hour

Fiona earns $14/hour

14 - 12 = 2

Fiona earns $2/hour more than Philip.

Answer:

Step-by-step explanation:

Angle DCE is congruent to Angle GDF

To find the measure of Angle CDF, you need to find the measure of Angle DCE first.

360° = 76° + 90° + Angle DCE + 90°

360° = 256° + Angle DCE

Angle DCE = 104°

Then you subtract 90° from 104° (Angle DCE) to get the measure of Angle CDF

104° - 90° = 14°

Angle CDF = 14°

Answer:

C. 26 degrees

For [tex]2\frac{2\\}{5}[/tex] feet, lace would cost 7.2 dollars as per the law of proportionality.

When two variables are directly or indirectly proportional to one another, their relationship may be expressed using the formulas y = kx or y = k/x, where k specifies the degree of correspondence between the two variables. The proportionality constant, k, is often used.

Given, Cheryl is buying lace for her dance costume. One foot of lace costs 3 dollars. Since,

1 feet lace = 3 dollars

[tex]2\frac{2}{5}[/tex] or 12/5 feet lace = 3 * 12/5 = 7.2

Therefore, According to the rule of proportionality, lace would cost 7.2 dollars for 12/5 feet.
