1) △ABC has A(-2,-2), B(-1,2) and C(2,1). After a dilation centered at the origin, △A'B'C' has A'(-4,-4), B'(-2,4) and C'(4,2). What is the scale
factor of the dilation?
a) -2
C) 2
b) -1/2
d) 1/2
Answer:
Option (C)
Step-by-step explanation:
If a point is dilated by a scale factor of 'k' about the origin,
Rule for the dilation,
(x, y) → (kx, ky)
By this rule, if ΔABC is dilated to form image triangle as ΔA'B'C',
A(-2, -2) → A'[2×(-2), 2×(-2)]
B(-1, 2) → B'[2×(-1), 2×(2)]
C(2, 1) → C'[2×(2), 2×(1)]
Therefore, scale factor of the dilation of the dilation will be k = 2
Option (C) will be the answer.

If matrix C represents (A-B)+A, the value of the entry represented by C41 is
Answer:
The value of the entry represented by [tex]c_{41}[/tex] is 12.
Step-by-step explanation:
Let [tex]A = \left[\begin{array}{ccc}-5&3&8\\3&6&-5\\5&-9&0\\7&3&4\end{array}\right][/tex] and [tex]B = \left[\begin{array}{ccc}-7&-8&-5\\7&9&2\\2&5&-7\\2&8&-7\end{array}\right][/tex].

A store buys a video game for the wholesale price of $29.95. The markup on the game is 80%. If sales tax is 7.5%, how much money would you need to buy the game?
Answer:
57.9532
Step-by-step explanation:
Given that:
Wholesale price = 29.95
Markup = 80%
Sales tax = 7.5%
Retail price of the game :
Price before sale tax:
Wholesale price * ( 1 + markup %)
29.95 * (1 + 0.8)
29.95 * (1.8)
$53.91
Sales tax = 7.5%
53.91 * (1 + 0.075)
53.91 * (1.075)
= 57.9532
Hence, $57.9532 will have to be paid

[tex] \Large{\boxed{\sf n = 8}} [/tex]
[tex] \\ [/tex]
Explanation:The perimeter of a rectangle is given by the following formula:
[tex] \Large{\sf P = 2L + 2W } [/tex]
Where:
P is the perimeter of the rectangle.L is its length.W is its width.[tex] \\ [/tex]
[tex] \Large{\boxed{\sf Given \text{:} } \begin{cases} \sf L &=\sf 3n - 9 \\ \sf W &=\sf n + 5 \\ \end{cases} } [/tex]
[tex] \\ [/tex]
Substitute these values into our formula:
[tex] \sf P = 2(3n - 9) + 2(n + 5) [/tex]
[tex] \\ [/tex]
Expand the expression of the perimeter using the following distributive property.
[tex]\green{\begin{gathered}\begin{gathered} \\ \boxed { \begin{array}{c c} \\ \blue{ \sf\boxed{ \sf Distributive \: property \text{ : } }} \\ \\ \sf\star \: \red{ \large{ a (b + c) = ab + ac }} \end{array}}\\\end{gathered} \end{gathered}}[/tex]
[tex] \\ [/tex]
We get:
[tex] \sf P = 2(3n) + 2(-9) + 2n + 2(5) \\ \\ \sf P = 6n - 18 + 2n + 10 \\ \\ \boxed{\sf P = 8n - 8 } [/tex]
[tex] \\ [/tex]
Since the perimeter is equal to 56, the value of n satisfies the following equality:
[tex] \sf 8n - 8 = 56 [/tex]
[tex] \\ [/tex]
To solve this equation, let's add 8 to both sides:
[tex] \sf 8n - 8 + 8 = 56 + 8 \\ \\ \sf 8n = 64 [/tex]

Now, divide both sides of the equation by 8:
[tex] \sf \dfrac{8n}{8} = \dfrac{64}{8} \\ \\ \\ \boxed{\boxed{\sf n = 8}} [/tex]

We could follow the same set of steps as shown back in part (i), but I'll show a different approach. Feel free to use the method I used back in part (i) if the visual approach doesn't make sense.
The diagram below is a visual way to organize all the terms. Many textbooks refer to it as "the box method" which helps multiply out any two algebraic expressions.
Each inner cell is found by multiplying the corresponding outer terms. For instance, in the upper left corner we have 2x*2x = 4x^2. The other cells are filled out the same way.
The terms in those four inner cells (gray boxes) are:
4x^2-14x-2x7The like terms here are -14x and -2x which combine to -16x, since -14+(-2) = -16.
We end up with the answer 4x^2-16x+7
Q and D are points on a polygon. Q' D' are points of the polygon under a translation. Determine the translation. Write your answer as (x,y).
Q (4,5) Q' (9,-1)
D (-5,-2) D' (0,-8)
Answer:
The translation is (5, -6)
Step-by-step explanation:
If the point (x, y) translated h unit right and k unit up, then its image is (x + h, y + k) and the translation is (h, k)If the point (x, y) translated h unit left and k unit up, then its image is (x - h, y + k) and the translation is (-h, k)If the point (x, y) translated h unit right and k unit down, then its image is (x + h, y - k) and the translation is (h, -k)If the point (x, y) translated h unit left and k unit down, then its image is (x - h, y - k) and the translation is (-h, -k)Let us solve the question
∵ The coordinates of point Q are (4, 5)
∴ x = 4 and y = 5
∵ The coordinates of point Q' are (9, -1)
∴ x' = 9 and y' = -1
→ That means x increased and y decreased ⇒ 3rd case above
∴ The point Q is moved to the right and down
→ By using the 3rd rule above ⇒ (x + h, y - k)
∵ x + h = 9
∵ x = 4
→ Substitute x by 4
∴ 4 + h = 9
→ Subtract 4 from both sides
∵ 4 - 4 + h = 9 - 4
∴ h = 5
∵ y - k = -1
∵ y = 5
→ Substitute y by 5
∴ 5 - k = -1
→ Subtract 5 from both sides
∵ 5 - 5 - k = -1 - 5
∴ -k = -6
→ Divide both sides by -1
∴ k = 6
∵ The translation is (h, -k) in the 3rd case
∵ h = 5 and k = 6
∴ The translation is (5, -6)
We can check the rule by finding D' the image of the point D
∵ D = (-5, -2)
∵ D' = (x + h, y - k)
∵ D' = (-5 + 5, -2 - 6)
∴ D' = (0, -8) as the given point D'
∴ The translation is correct

Reuben is making a replica of the US flag for his school project.
He uses a scale of 0.5 centimeter to 1 inch to draw the flag. The length of the scale drawing is 2.5 centimeters, and its width is 4.75 centimeters.
The perimeter of the scale drawing is (a7.25, b 11.875, c 14.5 d 47.5)centimeters
The perimeter of the actual flag is(a 14.5 b 29 c 47.5 d 95
Given: U.S Flag - rectangle in shape
scale of 0.5 cm = 1 in
length of the scale 2.5 cm
width of the scale 4.75 cm
perimeter of the scale = 2(L+W) = 2(2.5+4.75) =
2(7.25) = 14.5cm
perimeter of the actual flag is:
14.5cm * 1in/0.5cm = 29 inches
hope it helps!
Step-by-step explanation:
Perimeter of scale drawing
= 2 * (Length + Width)
= 2 * (2.5cm + 4.75cm)
= 2 * 7.25cm
= 14.5cm. (C)
Scale length to Actual length = 0.5cm : 1 in
Hence,
Perimeter of actual drawing
=> (1/0.5) * Perimeter of scale drawing
=> (1/0.5) * 14.5cm
=> 29 in. (B)

How long will it take l to catch up to c lauren can run 24 feet in 3 seconds clara can run 20 feet in 5 seconds clara has a 40 foot head start l will catch c in how many seconds after running how many feet
Answer:
They both will meet each other when they both have been running for 10 seconds
Lauren will run [tex]x=80\ \text{ft}[/tex] and Clara will run [tex]40\ \text{ft}[/tex]
Step-by-step explanation:
Velocity of Lauren
[tex]v_l=\dfrac{24}{3}\\\Rightarrow v_l=8\ \text{ft/s}[/tex]
Velocity of Clara
[tex]v_c=\dfrac{20}{5}\\\Rightarrow v_c=4\ \text{ft/s}[/tex]
Let distance traveled by Lauren be [tex]x[/tex]
As Clara has a 40 feet head start distance she will travel is [tex]x-40[/tex]
[tex]\text{Time}=\dfrac{\text{Distance}}{\text{Speed}}[/tex]
The time that will have passed when they both will meet will be the same for both of them so
[tex]\dfrac{x-40}{4}=\dfrac{x}{8}\\\Rightarrow 8x-320=4x\\\Rightarrow 8x-4x=320\\\Rightarrow 4x=320\\\Rightarrow x=\dfrac{320}{4}\\\Rightarrow x=80\ \text{ft}[/tex]
Time they will meet is [tex]\dfrac{80-40}{4}=\dfrac{80}{8}=10\ \text{s}[/tex].
So, Lauren will run [tex]x=80\ \text{ft}[/tex] and Clara will run [tex]x-40=80-40=40\ \text{ft}[/tex].
