The coordinates of the vertices of ΔPQR are (–2, –2), (–6, –2), and (–6, –5).

melamori03 [73]

<h3>Answer:</h3>

Yes, ΔPʹQʹRʹ is a reflection of ΔPQR over the x-axis

<h3>Explanation:</h3>

The problem statement tells you the transformation is ...

... (x, y) → (x, -y)

Consider the two points (0, 1) and (0, -1). These points are chosen for your consideration because their y-coordinates have opposite signs—just like the points of the transformation above. They are equidistant from the x-axis, one above, and one below. Each is a <em>reflection</em> of the other across the x-axis.

Along with translation and rotation, <em>reflection</em> is a transformation that <em>does not change any distance or angle measures</em>. (That is why these transformations are all called "rigid" transformations: the size and shape of the transformed object do not change.)

An object that has the same length and angle measures before and after transformation <em>is congruent</em> to its transformed self.

So, ... ∆P'Q'R' is a reflection of ∆PQR over the x-axis, and is congruent to ∆PQR.

Dr. Howser recently purchased two new fish tanks (Tank A and Tank B) to place in the waiting area of his office. Each fish tank

Masteriza [31]

Answer/Step-by-step explanation:

How many total fish is Dr. Howser planning on buying?

BOTH tanks hold 120 gallons

Tank A :

3 every 10 --> 120/10 ---> 12

So multiply 3 and 12 ----> 36

36 fishes in tank A

Tank B:

6 every 40 -----> 120/40 ----> 3

So multiply 6 by 3 ----> 18

18 fishes are held in tank B

Add them together:

18 + 36 ----> 54

ANSWER : Dr. Howser is planing on purchesing 54 fish all together.

What will be the ratio of the number of small fish he buys to the number of large fish that he buys

Small ---> 36 fish

Large ---> 18 fish

Small : Large ----> 36:18

ANSWER: 36:18

if you need it siplified it would be 2:1

Explain how the Quotient of Powers was used to simplify this expression. 2 to the fifth power, over 8 = 22 By finding the quotie

astraxan [27]

Answer:

we can do it by simplifying 8 to $2^3$ to make both powers base two, and subtracting the exponents.

Step-by-step explanation:

We have been given the expression $\frac{2^5}{8}=2^2$

8 can be rewritten as $2^3$

Hence, the given expression becomes

$\frac{2^5}{2^3}=2^2$

After subtracting the exponents on left hand side of the equation we get:

$2^2=2^2$

we can do it by simplifying 8 to $2^3$ to make both powers base two, and subtracting the exponents.
