Triangle PQR is transformed to triangle P′Q′R′. Triangle PQR has vertices P(8, 0), Q(6, 2), and R(−2, −4). Triangle P′Q′R′ has vertices P′(4, 0), Q′(3, 1), and R′(−1, −2).


Plot triangles PQR and P′Q′R′ on your own coordinate grid.


Part A: What is the scale factor of the dilation that transforms triangle PQR to triangle P′Q′R′? Explain your answer. (4 points)


Part B: Write the coordinates of triangle P′′Q′′R′′ obtained after P′Q′R′ is reflected about the y-axis. (4 points)

Answer:

in the explanation

Step-by-step explanation:

rs=2^2+4^2=20cm

sq root of 20=4.472135955 (round down to how much you like, probably 1dp)

qt=4^2+8^2=80cm

sq root of 80= 8.94427191

for the other pic just do \(\sqrt{80}\) takeaway \(\sqrt{20}\), which is 4.472135955 and round down to how much u like

part A: net a  

expatiation just fold it

part c: 63

12 + 36 + 15

Answer:

part A: net a  

part c: 63

12 + 36 + 15

An open circle is used to graph strict inequalities, which means the inequality does not include the value at the boundary. The inequalities that would have an open circle when graphed are:

x > 5.4

One-half less-than x

x > 0

Answer:

(3/2 m)^2 -(5n)^2^

Step-by-step explanation:

Answer: 9m^2 / 4  -  25n^2

Step-by-step explanation:

Use the identity: (a-b)(a+b)=a^2 - b^2
substitute values of a and b, where a=3/2m and b=5n.
The following simplifies to (3/2m)^2 - (5n)^2.

Answer: 1/2 + 2/3 + 4 /6  = 11/6

Step-by-step explanation:

1/2 + 2/3 + 4 /6

We need to find a common multiple, for the denominator. Let us choose 6, so we do not have to deal with large numbers.

Note that we do not change 4/6, since it already has a denominator of 6.

==> 3/6 + 4/6 + 4/6

Add;

==> 11/6

3/6 + 4/6 + 4/6  equal to 11/6

Hope this helped!

Answer:

Step-by-step explanation:

Formula for a cone:

V = 1/3 \(\pi\) r² h

Given:

\(\pi\) = 3.14

h=  12

Solution:

We need to find r to plug into formula

We can find r using pythagorean theorem on the triangle

c²=a²+b²               c is always the hypotenuse, longest side

15² = 12² + r²

225 = 144 + r²

r² = 81

r=9

V = 1/3 \(\pi\) r² h

V = 1/3 (3.14)(9²)(12)

V= 1017.36

Answer: Andre is ordering ribbon to make decorations for a school event. He needs a total of exactly 50.25 meters of blue and green ribbon. Andre needs 50% more blue ribbon than green ribbon for the basic design, plus an extra 6.5 meters of blue ribbon for accents. How much blue ribbon does Andre need to order?

Andre needs exactly 32.75 m of blue ribbons and 17.5 m of green ribbons.

Step-by-step explanation:

Andre requires exactly 50.25 m of blue and green ribbons. It is given in the question that there has to be 50% more blue ribbon than green ribbon, plus an extra 6.5 meters of blue ribbon for accents.

Answer:

32.75 m of blue ribbons and 17.5 m of green ribbons..........

Answer:

25

Step-by-step explanation:

4a +12 -2c + c

4( ) + 12 - 2( ) + ( )

4(4) + 12 - 2(3) + 3

16 + 12 - 6 + 3

28 - 6 + 3

22 + 3

25

Helping in the name of Jesus.

Therefore,  4a  +   12   -   2c   +   c  =   25

       a  =   4  

       c  =   3

        4a  +   12   -   2c   +   c

       (4)(4)  +  12  -     (2)(3)   +    3

         16     +   12   -   (2)(3)   +    3

         28      -            (2)(3)    +    3

         28     -   6     +     3

         22    +      3   =   25

Draw a conclusion:

     4a  +   12   -   2c   +   c   =  25

I hope this helps!

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.
