Which rule describes the translation?
PLEASE ANSWER
(x, y) → (x – 8, y – 3)
(x, y) → (x – 3, y + 8)
(x, y) → (x + 8, y – 3)
(x, y) → (x + 3, y + 8)
Answers
Justification:
1) From the figure you can tell that the original trapezoid ABCD was translated 8 units to the right and 3 units down to yield the trapezoid A'B'C'D'.
2) Translating 8 units to the right means: x → x + 8
3) Translating 3 units down means y → y - 3
4) Therefore, the pair (x,y) is transformed into the pair (x + 8, y - 3); that is the rule (x,y) → (x + 8, y - 3)

If F(x)=x-5 and G(x)=x^2, what is F(F(x))?
Answers
I really hope this helps
Given F(x)=x-5 and G(x)=x^2 you want to find F(F(x)).
In order to do this, you don't need to know what G(x) is. Just put F into F...
F(x)=x-5
F(x-5)=x-5-5
F(F(x))=x-10
This is the question that you asked, but the photo makes it look like they want you to do G(F(x)) so I will do that one too.
G(x)=x^2
G(x-5)=(x-5)^2
THEREFORE...
G(F(x))=(x-5)^2
A is the answer!
EXPLANATION:
Remember that a function is like a machine. F(x) is a machine and G(x) is also a machine. Plugging F into G is basically taking the output of the F machine and putting it into the G machine.
I really hope this helps! If you need a more detailed explanation, feel free to message me.

83 pounds of walnuts and 51 pounds of cashews were sold.
Answer: 83 pounds of walnuts and 51 pounds of cashew nuts.
Step-by-step explanation:
Let p be the amount of pounds for walnuts and n be the amount of pounds for cashew nuts that were sold.
Given : A nut mixture of walnuts and cashew nuts at a small fair is $1.00 per pound of walnuts and $3.10 per pound of cashew nuts.
Over the entire day, 134 pounds of the nut mixture were sold for $241.10.
Then, system of equation represents the given situation will be :-
[tex]p+n=134----------(1)\\\\p+3.10n=241.10----------(2)[/tex]
Eliminate (1) from (2), we get
[tex]2.10n=107.1[/tex]
Divide 2.10 from both sides , we get
[tex]n=51[/tex]
Put value of n in (1), we get
[tex]p+51=134\\\\\Rightarrow\ p=134-51=83[/tex]
Hence, the correct description will be : 83 pounds of walnuts and 51 pounds of cashew nuts.
Solve using substitution
Answers
Isolate x in the first equation. Subtract 3y from both sides
x+3y = 8
x+3y-3y = 8-3y
x = 8-3y
So we can see that x is the same as 8-3y
Now move onto the second equation
3x - 5y = -18
3( x ) - 5y = -18 ... rewrite x so it has parenthesis around it
3( 8-3y) - 5y = -18 ... replace x with 8-3y; solve for y
24-9y - 5y = -18
24-14y = -18
24-14y-24 = -18-24
-14y = -42
-14y/(-14) = -42/(-14)
y = 3
If y = 3, then x is...
x = 8-3y
x = 8-3*3
x = 8-9
x = -1
The x and y values are x = -1 and y = 3
Together they pair up to form the ordered pair (x,y) = (-1,3)
The solution is (-1,3)
If you graph the two original lines, then they cross at (-1,3)
A circle has a diameter with endpoints (7, -7) and (5, -3). What is the equation of the circle?
Answers
both can be found by using distance formula between 2 points:
[tex]d = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } \\ = \sqrt{ {(5 - 7)}^{2} + {( - 3 - - 7)}^{2} } \\ = \sqrt{ {(2)}^{2} + {(4)}^{2} } = \sqrt{4 + 16} [/tex]
[tex]d = \sqrt{20} = \sqrt{4} \times \sqrt{5} = 2 \sqrt{5} [/tex]
So our diameter is 2sr5, therefore our radius is half that: r = d/2 = 2sr5/2 = sr5
Now to calculate the center, go halfway between the x's and between the y's:
((7-5)/2 + 5, (-7--3)/2 + -3)
= ((2)/2 + 5, (-7+3)/2 + -3) = (1 + 5, (-4)/2 + -3)
= (1 + 5, -2 + -3) = (6, -5)
So our center is at (6, -5), where (h, k) is center for the formula, so h = 6, k = -5
Equation of a circle:
[tex] {(x - h)}^{2} + {(y - k)}^{2} = {r}^{2} \\ {(x - 6)}^{2} + {(y + 5)}^{2} = {( \sqrt{5}) }^{2} \\ {(x - 6)}^{2} + {(y + 5)}^{2} = 5 [/tex]
Final answer:
To find the circle's equation from its diameter's endpoints, calculate the circle's center using the midpoint formula, then determine the radius with the distance formula. Finally, use these values in the circle's standard equation.
Explanation:
To find the equation of the circle, we first need to determine its center and radius. The midpoint of the diameter will give us the center of the circle, and the distance from one of the endpoints to the midpoint will give us the radius.
Step 1: Find the Center of the Circle
The midpoint formula ((x1 + x2)/2, (y1 + y2)/2) gives us the center of the circle. Applying this to our points (7, -7) and (5, -3):
Center = ((7 + 5) / 2, (-7 - 3) / 2) = (6, -5)
Step 2: Calculate the Radius
We use the distance formula, √((x2 - x1)² + (y2 - y1)²), between one of the endpoints and the center:
Radius = √((7 - 6)² + (-7 + 5)²) = √(1 + 4) = √5
Step 3: Write the Equation
Using the standard equation, (x - h)² + (y - k)² = r², where (h, k) is the center and r is the radius:
Equation: (x - 6)² + (y + 5)² = 5
This equation gives the precise location and size of the circle based on its diameter's endpoints.

Given a right circular cone, you put an upside-down cone inside it so that its vertex is at the center of the base of the larger cone, and its base is parallel to the base of the larger cone. if you choose the upside-down cone to have the largest possible volume, what fraction of the volume of the larger cone does it occupy?
Answers
then x/b=h/r, and
volumeof smaller is 1/3pi(h-x)b^2, or
1/3pi(h-x)(x^2r^2/h^2=
1/3pi((x^2r^2/h)-(x^3r^2/h^2).
Now differinate with respect to x,
and set to 0, so
((2xr^2/h)-(3x^2r^2/h^2)=0,
so you get x=2/3h.
So, fraction is ((1/3pi(h-2/3h)(4/9r^2)/(1/3pir^2h)= 4/27
When a smaller, upside-down cone is placed inside a larger cone, both cones being similar and the vertex of the smaller one being at the center of the base of the larger one, the smaller cone would occupy 1/8 or 12.5% of the volume of the larger cone.
Explanation:The relationship between the volume of the larger cone and the smaller, upside-down cone placed inside it is represented through the formula for the volume of a cone, which is 1/3 * π * r² * h, where 'r' is the radius of the base and 'h' is the height. If you manage to place the smaller cone such that it has the largest possible volume (which will happen when the smaller cone is similar to the larger cone), the smaller cone will have a height and radius proportionately smaller than the larger one.
Thus, the volumes are proportional to the cube of their corresponding proportions, so the smaller cone will occupy 1/n³ of the volume of the larger cone, where 'n' is the proportion between their linear dimensions. In this particular set-up, the 'n' will equal 2 because when the vertex of the smaller cone is at the center of the base of the larger cone, the smaller cone's height is half that of the larger cone. Hence, the smaller cone will occupy 1/2³ = 1/8 or 12.5% of the volume of the larger cone.

The product of the binomials (7q - 5) and (7q + 5) is found using the difference of squares formula, resulting in 49q² - 25.
Explanation:
To find the product of the given expressions (7q - 5)(7q + 5), we can use the difference of squares formula, which states that (a - b)(a + b) = a² - b².
Here, a is 7q and b is 5.

(7q)² - (5)²49q² - 25This is because the mixed term +7q(-5) and the term -7q(+5) cancel each other out, leaving us with just the square terms.

It is given that △XYZ∼△DEF.
The corresponding sides of two similar triangles are proportional.
[tex]\frac{YZ}{EF}=\frac{XZ}{DF}[/tex]
[tex]\frac{10}{8}=\frac{15}{DF}[/tex]

Therefore we can say that if △XYZ∼△DEF, then the measure of DF is 12 meters.
A new board game uses special dice. Each die has eight sides. The game uses three of these special dice. How many outcomes are possible?
Answers
Final answer:
To find the number of possible outcomes when rolling three eight-sided dice, you multiply the number of outcomes of each die together, resulting in 512 total outcomes.
Explanation:
To determine how many outcomes are possible when rolling three eight-sided dice, we need to calculate the total number of combinations that can occur. Since each die has eight possible outcomes and the dice are rolled simultaneously, the number of outcomes for each die can be multiplied together to find the total number of outcomes for all three dice.
So, the calculation for the total number of outcomes is as follows:
8 (outcomes for die 1) × 8 (outcomes for die 2) × 8 (outcomes for die 3) = 512 total outcomes.
Therefore, there are 512 different possible outcomes when rolling three eight-sided dice.

∠V is calculated to be 70°.
When two triangles are similar (QRS ~ TUV), their corresponding angles are equal. This means:
∠Q corresponds to ∠T∠R corresponds to ∠U∠S corresponds to ∠VGiven ∠R = 47° and ∠Q = 63°, we know that ∠T = 63° and ∠U = 47°.
Since the sum of the angles in any triangle is 180°:
∠Q + ∠R + ∠S = 180°
Substituting the known values:
63° + 47° + ∠S = 180°
Solving for ∠S:
∠S = 180° - 63° - 47° = 70°
Therefore, ∠V = 70° because ∠S corresponds to ∠V in the similar triangles.
Complete question: Triangle QRS is similar to triangle TUV. ∠R=47°, ∠Q=63°. What is the measure of angle V?

To solve this problem , let's define the given information:
Let [tex]T[/tex] be the total number of kids at the summer camp:
[tex]T = 150[/tex]
Let [tex]A[/tex] be the number of kids who chose archery for their morning activity:
[tex]\frac{A}{T} = \frac{3}{5}[/tex]
Let [tex]D[/tex] be the number of kids from the archery group who also chose drama in the afternoons:
[tex]\frac{D}{A} = \frac{1}{4}[/tex]
We want to find the value of [tex]D[/tex], which represents the number of kids who chose both archery in the morning and drama in the afternoons.
We can set up the following equations:
[tex]\frac{A}{T} &= \frac{3}{5}[/tex]
[tex]A &= \frac{3}{5}T[/tex]
[tex]A &= \frac{3}{5}(150)[/tex]

Answers
Answer:
7/40
Step-by-step explanation:
once again not bothered
The probability she takes out exactly $2.50 is 7/40.
What is probability?Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.
For the given situation,
Number of coins in Kia bag = 10 coins
Number of $1 coins = 3
Number of 50 pence coins = 7
Kia takes at random 3 coins from the bag and the number of ways are
[tex]10C_{3} =\frac{(10)(9)(8)}{(1)(2)(3)}[/tex]
⇒ [tex]10C_{3} =\frac{720}{6}[/tex]
⇒ 120
Kia takes out exactly $2.50
So the combination could be two $1 coins and one 50 pence coins,
⇒ [tex](3C_{2}) (7C_{1} )[/tex]
⇒ [tex](\frac{(3)(2)}{(1)(2)} )(7)[/tex]
⇒ 21
Thus the probability she takes out exactly $2.50 is P(E) = [tex]\frac{21}{120}[/tex]
⇒ 7/40
Hence we can conclude that the probability she takes out exactly $2.50 is 7/40.
