Answer: C. Reflected over x axis

Step-by-step explanation:

When we reflect a figure over x-axis , then the magnitude of each corresponding coordinate remains same but the polarity of y-coordinate gets changed.

i.e. The rule for reflection across x-axis is :_

(x,y)\to(x,-y)

Given : Jon drew a triangle with coordinates (5,1), (7,-2) and (3,-1) he drew an image of the triangle with the coordinates of (5,-1), (7,2) and (3,1).

We can see that the magnitude of each corresponding coordinate remains same but the polarity of y-coordinate got change.

It means he made the image by reflecting it over x-axis.

Hence, C is the CORRECT answer.

Jon reflected over the x axis.

Reflecting over the x axis turns the y corrdinate into the opposite sign of the y coordinate. Here is the formula for that, if you want to take notes.

(x,y)—>(x,-y)

I hope this helped. Your answer to this question is D

Micha is playing a game with five cards numbered 1 through 5. He will place the cards in a bag and draw one card at random three
snow_tiger [21]

Answer: 0.008

Step-by-step explanation:

We have 3 experiments.

Each experiment is exactly the same: "Drawing the card with the number 5, out of a bag with five cards".

in a random selection all the cards have exactly the same probability of being drawn, so the probability of drawing the 5, is equal to the quotient between the number of cards with the 5 (only one) and the total number of cards in the bag (5) then the probability is:

p = 1/5.

And we want this event to happen 3 consecutive times, then the total probability is equal to the product of the probabilities for each event:

P = (1/5)*(1/5)*(1/5) = 1/125 = 0.008

Identify the transformation that carries the figure onto itself.
7nadin3 [17]

The polygon is reflected across the line y = −7 and rotate 540° clockwise about (−7, 8). Then the correct option is C.

<h3>What is a transformation of a point?</h3>

A spatial transformation is each mapping of feature space to itself, and it maintains some spatial correlation between figures.

The polygon is given below.

The polygon is reflected across the line y = −7 and rotate 540° clockwise about (−7, 8).

Then the correct option is C.

More about the transformation of a point link is given below.

Find the perimeter of a square whose area is 168cm square​
Elis [28]

Answer:

51.84 cm

Step-by-step explanation:

Solution,

We have,

Area of the square= L²

According to question,

168 cm²= L²

√168 cm²= L²

√(12.96 cm)² = L

12.96 cm= L

Now,

We got,

Length of the square= 12.96 cm

By using the formula of perimeter of square,

We have,

Perimeter of square= 4L

=4×12.96 cm

=51.84 cm

Hence, the perimeter of square is 51.84 cm.
