Please help, the only answer I've seen is A, but it's multiple choice.

Please find attached the dilated image of triangle ΔXYZ obtained by using a scale factor of 1.5, with the center of dilation at (0, 0), giving the coordinates of the vertices at the points X'(-6, 3), Y'(9, 0) and Z'(-3, -6).

A dilation transformation is one in which the lengths of a figure are scaled up or down.

From a similar question online, we have:

The vertices of the triangle ΔXYZ are: X(-4, 2), Y(6, 0), and Z(-2, -4)

The given center of dilation is (0, 0)

The scale factor of the dilation is 1.5

The coordinates of the points on the image following a dilation of the point (x, y) by a scale factor of k about the origin is given by the formula:

(x, y) [tex]\underrightarrow{R_k}[/tex] (k·x, k·y)

Therefore, the coordinates of the vertices of the image of the triangle ΔXYZ following a dilation by a scale factor of 1.5 are:

X(-4, 2) [tex]\underrightarrow{R_k}[/tex] X'(1.5×(-4), 1.5×2) = X'(-6, 3)

Y(6, 0) [tex]\underrightarrow{R_k}[/tex] Y'(1.5×6, 1.5×0) = Y'(9, 0)

Z(-2, -4) [tex]\underrightarrow{R_k}[/tex] (1.5×(-2), 1.5×(-4)) = (-3, -6)

The vertices of the dilated image of ΔXYZ, which is ΔX'Y'Z' are; X'(-6, 3), Y'(9, 0), Z'(-3, -6)

The credit hours that a student has to take for the two tuition costs to be equal is A. 250 + 200h = 300 + 180h

From the information, the tuition costs, C, for a local community college are modeled by C(h) = 250 + 200h

h = the number of credit hours taken.

The local state university has tuition costs, S, modeled by the function S(h) = 300 + 180h.

Therefore, the credit hours that a student have to take for the two tuition costs to be equal will be:

250 + 200h = 300 + 180h

200h - 180h = 300 - 250

The value of the Constant of Proportionality will be $2.19.

In the given question, it is stated that 3 pounds of grapes cost $6.57. We have to calculate and find out the Constant of Proportionality.

The constant of Proportionality is a constant term in the equation that does not vary and has a fixed value that represents a certain quantity in a given situation.

Here, we know that 3pounds cost $6.57. Taking:

y = Total Cost

x = Number of Pounds

c = Constant of Proportionality

We get the equation to represent the Total cost with respect to the number of pounds where c will be the proportionality constant which defines the unit price of a pound. The equation will be:

=> y = c*x

=> 6.57 = 3c

=> c = 2.19

Hence, we get the Constant of Proportionality $2.19

In the diagram given showing triangle QSP and triangle SQR, we are given that sides PQ and RS are congruent so also are angles PQS and RSQ.

However, we can also see that both triangles share a common side, side QS. Therefore, side QS is congruent to side SQ by the reflexive property of congruency.

What is a cone?

A cone is a three-dimensional geometric shape that tapers smoothly from a flat base (frequently, though not necessarily, circular) to a point called the apex or vertex.

We are given that radius of the cone as 5yd and slant height as 13yd

We first find the height using pythagoras theorem

Let height be h

by Pythagoras theorem we have

[tex]r^{2}+h^{2}=13^2\\ 5^2+h^2=169\\ h^2=144\\h=12[/tex]

Height of the cone is 12yds

Now volume of the cone is given by

[tex]V=[/tex]π[tex]r^{2}\frac{h}{3}[/tex]

Substituting the values in the equation we get

[tex]V=100[/tex]π yd^3

Now we find the surface area

The formula for surface area is

[tex]A=r(r+\sqrt{r^2+h^2} )[/tex]π

Substituting the values in the equation we get

[tex]A=90[/tex]π yd^2

Hence the surface area of the cone is 90π yd^2

Rafael is fertilizing his garden. The garden is in the shape of a rectangle. Its length is 16 feet and its width is 13 feet. Suppose each bag of fertilizer covers 26 square feet. How many bags will he need to cover the garden?​

step 1

Find the area of the garden

Remember that the area of a rectangle is equal to

A=L*W

we have

L=16 ft

W=13 ft

substitute

A=16*13

A=208 ft^2

step 2

we know that

each bag of fertilizer covers 26 square feet

so

Applying proportion

1/26=x/208

solve for x

x ----> number of bags

x=(1/26)*208

x=8 bags

therefore

After solving : 100!/12^50, we get 1.025513e+104

Here, 100 factorial or 100!

The result of multiplying an integer by each natural number below it is the factorial of that number.

A factorial can be symbolically denoted by the sign "!"

The first n natural integers are added together to form "n factorial," which is represented by the number n.

100! = 100 × 99 × 98 × .... × 3 × 2 × 1 = 9.332621544 E+157.

This product is too big to calculate manually and hence a calculator is used.

Now, 9.332621544 E+157 / 12 ^ 50 = 1.025513e+104

Hence, after solving 100!/12^50, we get 1.025513e+104

Answer: (y-(-43))=-7(x-6) and y=-7x-1

Step-by-step explanation:

1) Pick two points. I'll choose (3,-22) and (6,-43)

2) Next set it up in a rise-over-run function

-43 - (-22)

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

6    -  3

3) Solve

-21/3

-7

The slope is -7

4) Find the starting value.

You can do this by substituting two points in a slope-intercept equation(y=mx+b)

y=-7x+b

-22=-7(3)+b

-22= -21+b

-1=b

The starting value is -1.

5) Slope intercept form

We can put all the info together to find that the slope-intercept is:

y=-7x-1

6) Point-slope form:

Point slope form equation is this: y-y1=m(x-x1)

y1 and x1 are one of the points while keeping x and y as variables

So our final equation is (y-(-43))=-7(x-6)
