Step-by-step explanation:

[tex]\bf ~~~~~~~~~~~~\textit{angle between two vectors } \\\\ cos(\theta)=\cfrac{\stackrel{\textit{dot product}}{u \cdot v}}{\stackrel{\textit{magnitude product}}{||u||~||v||}} \implies \measuredangle \theta = cos^{-1}\left(\cfrac{u \cdot v}{||u||~||v||}\right) \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \begin{cases} u=i+\sqrt{7}j\implies &<1,\sqrt{7}>\\\\ v=-i+9j\implies &<-1,9> \end{cases} \\\\[-0.35em] ~\dotfill[/tex]

Step-by-step explanation:

we know that

$39.95 -----> represent the 100%

so

The difference of prices is equal to ($39.95-$23.97)=$15.98

Using proportion

Find the percentage of the difference

100/39.95=x/15.98

x=100*15.98/39.95

Answer:

d = sqrt(101)

Step-by-step explanation:

To find the distance between two points, we use the formula

d =sqrt ((x2-x1)^2 + (y2-y1)^2)  where (x1,y1) and (x2,x2) are the points

d = sqrt ((-13--3)^2 + (-23--22)^2)

d = sqrt ((-13+3)^2 + (-23+22)^2)

d = sqrt((-10)^2 + (-1)^2)

d = sqrt(100)+1)

d = sqrt(101)

Wouldn’t it be 36.7 because that’s the arch am I right?

Answer:

The measure of arc CD is 114.6°.

Step-by-step explanation:

Let the center of the circle be O and OP is perpendicular to CD at point point P.

The perpendicular line from the center of circle divide each chord in two equal parts. so, CP=DP.

[tex]CP=\frac{CD}{2}=\frac{36.7}{2}=18.35[/tex]

In a right angles triangle,

[tex]\sin\theta =\frac{opposite}{hypotenuse}[/tex]

In a right angles triangle OPC,

[tex]\sin\angle POC =\frac{18.35}{21.8}[/tex]

[tex]\angle POC =\sin^{-1} (\frac{18.35}{21.8})[/tex]

[tex]\angle POC \approx 57.3[/tex]

In triangle OPC and OPD,

[tex]OC=OD[/tex]                  (Radius)

[tex]OP=OP[/tex]                  (Reflexive property)

[tex]CP=DP[/tex]                   (Altitude on chord from center)

By SSS postulate

[tex]\triangle OPC\cong \triangle OPD[/tex]

[tex]\angle POC\cong \angle POD[/tex]                      (CPCTC)

[tex]\angle POC=\angle POD[/tex]

The measure of angle COD is

[tex]\angle COD=\angle POC+\angle POD[/tex]

[tex]\angle COD=2\angle POC[/tex]

[tex]\angle COD=2(57.3)[/tex]

[tex]\angle COD=114.6[/tex]

Therefore the measure of arc CD is 114.6°.

Answer:

0.34

Step-by-step explanation:

Do the inverse operation so;

0.034 / 1/10 = 0.34

Now go back and subsitute,

0.34 * 1/10 = 0.034

In the equation □ x 1/10 = 0.034, the missing value is 0.34 as obtained by isolating □ on one side, i.e., □ = 0.34.

The equation presented in the question is □ x 1/10 = 0.034. The missing value is the number that should be multiplied by 1/10 to result in 0.034. To solve for this missing value, we can rearrange the equation using the basic algebraic method. We isolate the missing value (□) on one side by dividing both sides of the equation by 1/10. This results in □ = 0.034 / (1/10), which simplifies further to □ = 0.34. Therefore, the missing value in the equation □ x 1/10 = 0.034 is 0.34.

Answer:

Mr. Johnson would have ordered 18816 jaw breakers.

Step-by-step explanation:

Multiply 392 by 48

Mr. Johnson ordered a total of 18816 jawbreakers by multiplying the number of boxes (48) by the number of pieces of candy per box (392).

The question involves calculating the total number of jawbreakers Mr. Johnson ordered. To do this, we need to multiply the number of boxes ordered by the number of pieces of candy per box.

Step-by-step calculation:

Identify the number of boxes ordered: 48 boxes.

Identify the number of candies per box: 392 pieces.

Multiply the number of boxes by the number of candies per box to find the total: 48 boxes × 392 pieces/box = 18816 jawbreakers.

Therefore, Mr. Johnson ordered a total of 18816 jawbreakers.

Answer:

y=5x-10

Step-by-step explanation:

slope intercept form is y=mx+b

since we know it is parallel to y=5x-1, we know that it has the same slope of 5.

So, we plug it in:

y=mx+b

y=5

x=3

(taken from point (3,5))

m=5

(taken from parallel line)

5=(5)(3)+b

5=15+b

b=-10

The equation would be y=5x-10

2x - 5 = x - 7

First, let's subtract x from both sides:

2x - x - 5 = x - x - 7

x - 5 = -7

Now, let's add 5 to both sides:

x - 5 + 5 = -7 + 5

x = -2

Answer:

x = -2

Step-by-step explanation:

2x - 5 = x - 7

2x - x - 5 = -7

2x - x = -7 + 5

Now we have isolated x

2x - x = 5 - 7

2x - x = -2

x = -2

Multiply the negative sign into the second bracket and get rid of both brackets

-3y-x-5y+8x

Collect like terms

-8y+7x

Answer:

B:  -8y + 7x

Step-by-step explanation:

Start with (-3y-x)-(5y-8x).  This is a subtraction problem.  Subtract 5y from -3y, obtaining -8y.  Next, subtract -8x from -x; this is equivalent to  -x - (-8x), or 7x.

Then the difference -x + 8x = 7x.

Combining the x and y results, we get   B:  -8y + 7x.

Answer:

Changing value of "a" changes the amplitude of the sine graph.

Step-by-step explanation:

Question says to find about how does the a value affect your sine graph.

General equation of sine function can be given as:

There value of "a" gives amplitude.

So changing value of "a" changes the amplitude of the sine graph.

Answer:

We have

sale price + 6% x sale price = $121.37;

Then

(106/100) x sale price = $121.37;

sale price = $121.37 x 100 / 106;

sale price = $12137 / 106;

sale price = $114.50;

Step-by-step explanation:

To find the sale price of a dress before a 6% tax added up to a total of $121.37, divide the total by 1.06. The original sale price was $114.50.

The student is asking how to calculate the sale price of a dress before tax when the total cost, including a 6% tax, was $121.37. To find the sale price before taxes, you need to divide the total cost by 1 plus the tax rate expressed as a decimal.

First, convert the percentage to a decimal, which gives us 0.06 for a 6% tax. Then, add 1 to the tax rate (1 + 0.06 = 1.06) and divide the total cost by this sum to get the original price:

Sale price = Total cost / (1 + Tax rate)
Sale price = $121.37 / 1.06
Sale price = $114.50 (rounded to the nearest penny)

Therefore, the original sale price of the dress was $114.50.

Answer: Option C.

Step-by-step explanation:

The equation of the line in slope-intercept form is:

[tex]y=mx+b[/tex]

Where the slope is "m" and the intersection of the line with the y-axis is "b".

Given the function f(x) in the form [tex]f(x)=x[/tex], you can identify that:

[tex]m=1\\b=0[/tex]

This means that the line passes through the origin (0,0)

And from the function g(x) in the form [tex]g(x)=x-16[/tex], , you can identify that:

[tex]m=1\\b=-16[/tex]

This means that the line of the function g(x) and the line of the function f(x) have the same slope, but the line of g(x) passes through the point (0,-16)

Therefore, the graph of f(x) must be shifted 16 units down to produce the graph of g(x)
