Answer: Rotation
Step-by-step explanation:
From the figure , we can observe that both figure A and b are absolutely congruent.
To translate a figure to make congruent images , we use rigid motions (Translation, Reflection, Rotation)
It is Rotation because of we move Figure A 180 degrees clockwise about the fixed point O, we will get Figure B .
It cannot be reflection because both figures are not mirror images.
It cannot be translation because all points on Figure A is not moving , as point O remained at same position throughout this which is not possible in translation.

Daniel growing corn in a square field. The length of one side is 100 yards he needs to purchase fertilizer for the corn field. Each bag covers 50 square yards .How many bags do he need?
Answers
Answer:
200 bags are needed
Step-by-step explanation:
First let us determine the area of the corn field:
Shape of cornfield = square
Area of a square = Length × Length
where: Length = 100 yards
∴ Area = 100 × 100 = 10,000 square yards
1 bag of fertilizer is needed to cover 50 square yards:
50 square yards = 1 bag of fertilizer
[tex]\therefore 1 \ square\ yard\ = \frac{1}{50}\ bag\\10,000\ square\ yards\ =\ \frac{1}{50} \times 10,000 = \frac{10l000}{50} \\ = 200 bags[/tex]
Hence, 200 bags are needed.

Mr. Freeman has a square cornfield. Which of the following could be the
area of the cornfield if the sides are measured in whole numbers?
150 square acres
189 square acres
200 square acres
225 square acres

Step-by-step explanation:
Notice that 15 squared = (3 * 5)^2 = 9 * 25 = 225.
So the area of the cornfield can be 225 square acres.
Point E is on line segment DF. Given DE = 2x, EF = 2x – 6, and
DF = 3x + 5, determine the numerical length of EF.
Answer: EF =
Answers
Answer:
EF is 16.
Step-by-step explanation:
So we know that Point E is somewhere on Line DF. In other words, DE plus EF must equal DF. In an equation, this is:
[tex]DF=DE+EF[/tex]
We are given that DE is 2x, EF is 2x-6, and DF is 3x+5. So, substitute:
[tex](3x+5)=(2x)+(2x-6)[/tex]
Now, solve for x.
On the right, combine like terms:
[tex]3x+5=4x-6[/tex]
Subtract 4x from both sides:
[tex]-x+5=-6[/tex]
Subtract 5 from both sides:
[tex]-x=-11[/tex]
Divide both sides by -1:
[tex]x=11[/tex]
Now that we know x is 11, substitute this back into the equation for EF to find EF.
[tex]EF=2x-6[/tex]
Substitute 11 for x:
[tex]EF=2(11)-6[/tex]
Multiply:
[tex]EF=22-6[/tex]
Subtract:
[tex]EF=16[/tex]

How do I solve this problem?
Answers
Answer:
Step-by-step explanation:
The first 2 pieces of this function agree at pi/4, so we will set them equal to each other and sub in pi/4 for x to solve for k:
[tex]ksin(\frac{\pi}{4})+(\frac{\pi}{4})^2=\frac{\pi}{4}+2[/tex] and
[tex]k(\frac{\sqrt{2} }{2})+\frac{\pi^2}{16}=\frac{\pi}{4}+2[/tex] and we'll multiply everything by 16 to get rid of the fractions. Doing that gives us:
[tex]8k\sqrt{2}=4\pi+32-\pi^2[/tex] and
[tex]k=\frac{4\pi+32-\pi^2}{8\sqrt{2} }[/tex] so
k = 3.067
The next one is a bit tricky if you're not up on your natural log equations.
Again, we set these equal to each other because they meet at the value of e. We sub in e for x and solve for m:
[tex]x +2=mlne^x[/tex]
We'll sub in e for x. ln of e to the x power is equal to x, so
e + 2 = me and
[tex]m=\frac{e+2}{e}[/tex] so
m = 1.736
Hope that helps!

b. $6,355.10
c. $6,324.00
d. $6,220.00
Answers
Answer:
Option c.
Step-by-step explanation:
It is given that the piecewise function represents the Social Security taxes for 2009.
[tex]Tax=\begin{cases}0.062x & \text{ when } 0< x < 106,800 \\ \$6,621.60 & \text{ when } x > 106,800 \end{cases}[/tex]
We need to find Rachel's security tax if she earned $102,000 in 2009.
Since 102,000 lies in [tex]0<x<106,800[/tex], therefore
[tex]Tax=0.062x[/tex]
Put x=102000.
[tex]Tax=0.062(102000)[/tex]
[tex]Tax=6324[/tex]
So, the Social Security tax is $6324.
Therefore, the correct option is c.

(x + 9)(x - 2) - 9x - 6
What is equivalent?
Answers
Answer:
We can find an expression equivalent to the one given by expanding the expression given,
[tex](x + 9)(x - 2) - 9x - 6\\x^2-2x+9x-18-9x-6\\x^2-2x-24[/tex]
So [tex]x^2-2x-24[/tex] is a possible expression.
The required expression equivalent to (x + 9)(x - 2) - 9x - 6 is (x + 4)(x - 6).
Given that,
(x + 9)(x - 2) - 9x - 6, an equivalent expression is to be determined.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
= (x + 9)(x - 2) - 9x - 6
= x² + 9x -2x -18 - 9x - 6
= x² - 2x - 24
= x² -6x + 4x - 24
= x (x - 6) + 4 (x - 6)
= (x + 4)(x - 6)
Thus, the required expression equivalent to (x + 9)(x - 2) - 9x - 6 is (x + 4)(x - 6).

What are the coordinates of Q'Q
Answers
Q is located at (0,6)
The translation rule is [tex](x,y) \to (x+7,y-5)[/tex] which says to add 7 to the x coordinate and subtract 5 from the y coordinate. Doing that to (0,6) moves it to (7,1) which is where point Q' is located.
In other words, if you shift point Q(0,6) seven units to the right and five units down, then it arrives at Q ' (7,1)
Answer: (7, 1)The coordinates of Q' are [tex]Q'(x,y) = (7, 1)[/tex].
Note - There are typing mistakes in the question. Correct statement is presented below:
Point Q' is the image of [tex]Q(0,6)[/tex] under the translation [tex](x,y) \to (x+7, y-5)[/tex]. What are the coordinates of Q'.
In this question we should use the point and the operation described in statement. Vectorially speaking, a translation is defined by the following operation:
[tex]P'(x,y) = P(x,y) + T(x,y)[/tex] (1)
Where:
[tex]P(x,y)[/tex] - Original point.[tex]P'(x,y)[/tex] - Translated point. [tex]T(x,y)[/tex] - Translation vector.If we know that [tex]Q(x,y) = (0,6)[/tex], then the coordinates of [tex]Q'(x,y)[/tex] are:
[tex]Q'(x,y) = Q(x,y) + (7,-5)[/tex]
[tex]Q'(x,y) = (0,6) + (7,-5)[/tex]
[tex]Q'(x,y) = (7, 1)[/tex]
The coordinates of Q' are [tex]Q'(x,y) = (7, 1)[/tex].
