Answer:

Option A. (7, 3)

Step-by-step explanation:

When C is rotated 90° counterclockwise about the point A then C' will come parallel to the point A.

Now we can find the coordinates of the image of point C.

Distance between point A and C is 4 units, so x coordinates of C' (image) will be = 3 + 4 = 7

And y coordinates will remain as 3.

So the new image point C' will be (7, 3)

Option A. (7, 3) is the correct option.

counter clockwise would be rotating it up to the right.

C is 4 spaces away from A ,

 A is on X3 & Y3 so 4 +3 = 7

so it would be x7 & Y3 so (7,3), the first answer

Triangle ABC has been reflected over the x-axis to create triangle A'B'C'. Which of the following statements is true?
Leto [7]

Answer:

A ' = (-2, -3)

B ' = (0, -3)

C ' = (-1, 1)

=======================================================

Explanation:

To apply an x axis reflection, we simply change the sign of the y coordinate from positive to negative, or vice versa. The x coordinate stays as is.

Algebraically, the reflection rule used can be written as

Applying this rule to the three given points will mean....

Point A = (-2, 3) becomes A ' = (-2, -3)

Point B = (0, 3) becomes B ' = (0, -3)

Point C = (-1, -1) becomes C ' = (-1, 1)

The diagram is provided below.

Side note: Any points on the x axis will stay where they are. That isn't the case here, but its for any future problem where it may come up. This only applies to x axis reflections.

Clarissa helps her mom put the 200-Newton lawn mower in the back of her mom’s truck. They lift the mower up from the ground to t
Anarel [89]

Answer:

220 N * m or 220 J

Step-by-step explanation:

We have that the work formula would be the applied force multiplied by the distance traveled, that is:

W = F * d

In this case the F is 200 N and the distance is 1.1 meters, therefore we replace:

W = 200 * 1.1

W = 220 N * m = 220 J

Therefore the work carried out by Clarissa and her mom is 200 joules.

Answer:

Hey there!

40 is 25% of 120.

We can see that 30 is 25% of 120, because 0.25(120)=30.

Hope this helps :)
