Answer:

A reflection about y=x

Step-by-step explanation:

The 4 transformations are

Let eliminate which ones won't work.

A translation wouldn't flip the triangle in a different direction after translating it so we won't translate it.

A dilation changes the length for the triangle but the triangles are congruent so we won't dilate it.

A rotation about the orgin wouldn't work nor a specific point so a rotation isnt going to work.

A reflection will work so what will we reflect about.

A reflection makes a reflected point equidistant from the line of reflection and their original point is equidistant from line of reflection.

So let find the midpoint of all the points and find a line where all of them are on.

The midpoint respectively are

Let find the line that includes both these points.

[tex] \frac{6 - 4}{6 - 4} = \frac{2}{2} = 1[/tex]

So this means our slope is x. The y value corresponds with the x value so the answer is

[tex]y = x[/tex]

So the answer is

"A reflection about y=x

Answer:

? =50

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos ? = adj/hyp

Taking the inverse cos of each side

cos^-1 (cos ?) = cos^-1( 14/22)

? =50.47880364

To the nearest degree

Answer:

The value of the standardized z-test statistic is -6.4.

Step-by-step explanation:

The test statistic is:

[tex]z = \frac{X - \mu}{s}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, and s is the standard error.

0.28 is tested at the null hypothesis:

This means that [tex]\mu = 0.28[/tex]

p ^ 0.216 with SE 0.01

This means that [tex]X = 0.216, s = 0.01[/tex]

Then

[tex]z = \frac{X - \mu}{s}[/tex]

[tex]z = \frac{0.216 - 0.28}{0.01}[/tex]

[tex]z = -6.4[/tex]

The value of the standardized z-test statistic is -6.4.

Answer:

c. A number relatively close to 100.

Step-by-step explanation:

Given

[tex]Range: 0 \to 1[/tex]

[tex]N =1000[/tex] --- i.e. the cells

Required

Number of cells that contains less than or equal 0.2

Less than or equal 0.2 means that the numbers are approximately 20% of the whole distribution

So, to calculate the number (n) of these cells, we do the following computation

[tex]n = 20\% * N[/tex]

[tex]n = 20\% * 1000[/tex]

[tex]n = 200[/tex]

200 is closer to 100 than 500. Hence, (c) is correct

Answer:

14 = x and 2.5 = y

Step-by-step explanation:

For ABCD - the top is 8 and the sides are 11. 11 minus 8 is 3. 11 plus 3 equals 14, that’s x.

For GHIJ - the bottom is 8 and both sides are 5.5. So 8 minus 5.5 is 2.5. That’s y.

Q10/ scale factor of polygon ABCD to polygon GHIJ = 11/5.5 = 2

Q11/ scale factor of polygon GHIJ to polygon ABCD = 1:2

Q12/ x = 8 × 2 = 16

        y = 8 / 2 = 4

Q13/ ABCD ⇒ label x as 16, y as 4

         GHIJ ⇒ label HI line to 5.5

Q14/ ratio = 46 : 23

                = 2 : 1

Answer:

It is a Cuboid

Area of the base = 12x9

Area of the top = 12x9

Area of the right lateral faces = 9x7

Area of the left lateral faces = 9x7

Area of the front face = 12x7

Area of the rear face = 12x7

Total surface area is the sum of above (please do it yourself)

The volume = base surface Area x height

= 12x9x7 = 756

Be reminded to put in the right unit for Area and volumn

Answer:

its a prism

Step-by-step explanation:

to find area of all the sides, you multiply the bottom and top measurements.

12 x 7 is 84cm[tex]^{2}[/tex]

12 x 9 is 108[tex]cm^{2}[/tex]

9 x 7 is 63[tex]cm^{2}[/tex]

for surface area, add the area of all the faces

63x2+108x2+84X2=510

volume is length x width x hight

12 x 9 x 7 = 756 [tex]cm^{3}[/tex]

Answer:

Answer:

The correct answer is [tex]y = \sqrt{x} - 4[/tex]

Step-by-step explanation:

We are given:

[tex]y = \sqrt{x}[/tex]

The domain of the function is [0, infinity).

In the graph:

The domain(values of x), is still [0, infinity). Thus, there was no change in the domain, which rules out the first and the third option.

Change:

The change in the graph is that the function starts 4 units down(sqrt(0) = 0, in the graph when x = 0, y = -4). That is, 4 is subtracted from the function, and thus the correct answer is [tex]y = \sqrt{x} - 4[/tex]

Step-by-step explanation:

So as you can see in my picture i drew those lines, they are vertically opposite from each other.

Hope this helps!

Good Luck!

Please mark me bralinest if you can :)

Answer:

Vertical

Step-by-step explanation:

<AGB and <EGD are vertical angles because they are vertically opposite from each other since they were created from two lines crossing.

-You know that they aren't adjacent because they aren't next to each other and don't share a side or a vertex.

-They can't be supplementary because they don't add up to 180 degrees

-They can't be complementary because they don't make up 90 degrees

Answer:

slope is -2

Step-by-step explanation:

1. go to geogebra.org/classic (this is a graphing calculator)

2. enter your two points by using the second button on the top of the screen

3. connect a line from one point to the other using the 3rd button on the top of the screen

4. click on the line and it shall tell you the equation, including the slope :O))))

the slope is -2 and the equation is y = -2x + 18

Answer:

-4/2 = -2/1 = -2

Step-by-step explanation:

Slope is rise/run or as the formula states, Y2 - Y1 / X2 - X1

If you substitute the known values into this formula, you will get

4 - 8 / 7 - 5

This simplifies to

-4 / 2

You can then simplify further if needed:

-4/2 = -2/1 = -2

Answer:

C) It is often difficult to solve complicated problems with tables alone.

Step-by-step explanation:

Tables can be regarded mathematical tools used in representation of data in very organised form. The arrangements is in form of rows and columns which often gives description of an array of data in table format. Tables are best use in solving simple problems. Tables helps to show results for calculation that has varying arguments. It should be noted that the disadvantage to using tables is that It is often difficult to solve complicated problems with tables alone.

The value of a is 9.

A factor of polynomial P(x) is any polynomial which divides evenly into P(x).

For finding the factor of a polynomial we will perform following steps:

According to the given question.

We have a cubic polynomial [tex]x^{3} -4x^{2} +ax -2a[/tex]

Also, x - 3a is a factor of the given polynomial.

⇒ [tex]x - 3 = 0[/tex]

⇒[tex]x = 3[/tex]

⇒ 3 is the one solution of the given cubic polynomial.

If 3 is the one solution of the cubic polynomial then it must satisfy the equation (i).

So, substitute the value of x in the given polynomial.

[tex](3)^{3} -4(3)^{2} + a (3) - 2a = 0[/tex]

⇒[tex]27 -4(3)^{2} +a(3) -2a=0[/tex]

⇒[tex]27 - 36 + 3a - 2a= 0[/tex]

⇒[tex]-9 + a = 0[/tex]

⇒ [tex]a = 9[/tex]

Therefore, the value of a is 9.

Answer: 240 feet

Step-by-step explanation:

What you could do is find the area of the whole thing. 12x25 is 300. Then, you can find the area of the white part, which is 60, because you multiply 12x5. then, you would subtract 60 to 300, which would get you to 240 feet.

Answer:

The answer is : 240cm² for the shaded part

The unshaded part is = 60cm²

The whole rectangle = 300cm²

Step-by-step explanation:

Area is = WL

W = width (while the) L= length

The Area = 25 × 12 = 300

The area of the full rectangle is = 300

The unshaded part is = 5 × 12 = 60

So the shaded part is = 300 - 60 = 240cm²

[tex]so \: the \: answer \: is \: = 240cm^{2} [/tex]

How to solve your problem

−2(1−4)=3+8

-2(1-4x)=3x+8−2(1−4x)=3x+8

Solve

1)

Rearrange terms

−2(1−4)=3+8

-2({\color{#c92786}{1-4x}})=3x+8−2(1−4x)=3x+8

−2(−4+1)=3+8

-2({\color{#c92786}{-4x+1}})=3x+8−2(−4x+1)=3x+8

2)

Distribute

−2(−4+1)=3+8

{\color{#c92786}{-2(-4x+1)}}=3x+8−2(−4x+1)=3x+8

8−2=3+8

1/2 * 1/2 = (1/2)² = 1/4

1/4 * 400 = 100

Answer:

A = $174,742.21

A = P + I where

P (principal) = $100,000.00

I (interest) = $74,742.21

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 8/100

r = 0.08 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 100,000.00(1 + 0.08/12)(12)(7)

A = 100,000.00(1 + 0.006666667)(84)

A = $174,742.21

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $100,000.00 at a rate of 8% per year compounded 12 times per year over 7 years is $174,742.21.
