which equation represents a line which is parallel to the y axis?

The measure of RS to the nearest hundredth is 23.09 m

From the given figure, we have the following parameters

Adjacent to <R = RS

hypotenuse = 20cm

Using the theorem;

cos theta = opp/hyp

cos<R = RS/20
cos 30 = RS/20
RS = 20/cos30

RS =23.094 m

Hence the measure of RS to the nearest hundredth is 23.09 m

Step-by-step explanation:

The coordinates of the Rhombus after the dilation is W' ( 3 , 0 ) , X' ( 12 , -3 ) , Y' ( 15 , -12 ) and Z' ( 6 , -9 )

Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent

The result of dilation is that the shapes and boundaries of objects in the input image are expanded or thickened. It is often used in conjunction with other morphological operations such as erosion, opening, and closing to manipulate and enhance images.

Given data ,

Let the coordinates of the rhombus be represented as WXYZ

where W' ( 1 , 0 ) , X ( 4 , -1 ) , Y ( 5 , -4 ) and Z ( 2 , -3 )

Now , the dilation scale factor is k = 3 centered at origin

So , result of this transformation is an image with the same shape as the original

The coordinates of the dilated figure is W'X'Y'Z'

where W' ( 3 , 0 ) , X' ( 12 , -3 ) , Y' ( 15 , -12 ) and Z' ( 6 , -9 )

Hence , the dilation is solved

Answer:

D.144

Step-by-step explanation:

[tex]\frac{7}{x} = \frac{84}{156-x}[/tex]

⇔ 84x = -7x + 1092

⇔ 91x = 1092

⇔ x = 12

⇒ AC = 156 - x = 156 - 12 = 144

Hello! answer: angle n is. 51

Step-by-step explanation:

This is a complementary angle meaning it will add up to 90 degrees so...

3 × 8 = 24 24 + 15 = 39

2 × 8 = 16 16 + 35 = 51

39 + 51 = 90 therefore angle n is 51 hope that helps!

[tex]\sqrt{13}[/tex]

Step-by-step explanation:

Given a vector < x, y > then its magnitude is

[tex]\sqrt{x^2+y^2}[/tex]

Given the directed line segment

P (0, 0 ) → Q (3, 2 ) then

PQ = q - p = (3, 2 ) - (0, 0 ) = < 3 - 0, 2 - 0 > = < 3 , 2 >

| PQ | = [tex]\sqrt{3^2+2^2}[/tex] = [tex]\sqrt{9+4}[/tex] = [tex]\sqrt{13}[/tex]

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

Work Shown:

We use the first term to build to the second term.

Plug in n = 2

f(n) = -4f(n-1) + n

f(2) = -4f(2-1) + 2 ..... n replaced with 2

f(2) = -4f(1) + 2

f(2) = -4*4 + 2 ......... f(1) replaced with 4; since f(1) = 4

f(2) = -16 + 2

f(2) = -14

The second term is -14

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

Repeat for n = 3

f(n) = -4f(n-1) + n

f(3) = -4f(3-1) + 3 ..... n replaced with 3

f(3) = -4f(2) + 3

f(3) = -4*(-14) + 3 ......... f(2) replaced with -14

f(3) = 56 + 3

f(3) = 59

The third term is 59

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

We keep going until we get to f(5)

Plug in n = 4

f(n) = -4f(n-1) + n

f(4) = -4f(4-1) + 4 ..... n replaced with 4

f(4) = -4f(3) + 4

f(4) = -4*(59) + 4 ......... f(3) replaced with 59

f(4) = -236 + 4

f(4) = -232

The fourth term is -232

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

Just one more section

Plug in n = 5

f(n) = -4f(n-1) + n

f(5) = -4f(5-1) + 5 ..... n replaced with 4

f(5) = -4f(4) + 5

f(5) = -4*(-232) + 5 ......... f(4) replaced with -232

f(5) = 928 + 5

f(5) = 933

The fifth term is 933

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

As you can see, recursive sequences can get tedious for fairly large values of n. We need to compute every term before f(5) to figure it out. So if your teacher needed you to compute something like f(10), then it would get even worse. Sometimes it's possible to find a closed formula for it, but it may be tricky to find.

Answer:

Kim will need to spend 67 minutes on her sixth ride

Step-by-step explanation:

Represent the number of minutes of her sixth ride by m.

Then the average number of minutes is

53 + 43 + 56 + 54 + 45 + m

---------------------------------------- = 53

                      6

Multiplying both sides of this equation by 6 yields

6(53 + 43 + 56 + 54 + 45 + m)

--------------------------------------------- = 6(53)

                        6

which simplifies to

 251 + m

---------------- = 318

or  251 + m = 318.  Subtract 251 from both sides to obtain the value of m:

m  = 318 - 251 = 67

Kim will need to spend 67 minutes on her sixth ride to attain an average ride length of  53 minutes.i

The total surface area is given by the formula ...

  SA = 2πr(r +h)

For one box, the area is ...

  SA = 2(3.14)(4 in)(4 in +9 in) ≈ 326.6 in² . . . . area of one box

__

There are 144 square inches in a square foot, so the area required for 1500 boxes is ...

. This can be plotted.

The quadratic can also be factorised,

y

(

which tells us that the quadratic has roots of -2 and -4, and crosses the

Finally, we observe that if we plug
