What are the coordinates of the vertices of the image after a 90-degree counter-clockwise rotation about the origin?
(2,3)
(-3,-1)
(2, -1)

Answers

Answer 1
Answer:

The coordinates of the vertices of the image after the 90-degree counter- clockwise rotation about the origin is :

  • ( - 3, 2 )
  • ( 1, -3 )
  • ( 1, 2 )

How to rotate 90-degree counter- clockwise rotation about the origin?

To perform a 90-degree counterclockwise rotation about the origin, follow these steps:

  • Write down the coordinates of the point you want to rotate. Let's call the point ( x , y).
  • To perform a counterclockwise rotation, switch the x and y-coordinates and negate the new x-coordinate. The new coordinates will be ( - y , x).

This means that the vertices will become :

( 2 , 3) ⇒ ( - 3, 2 )

( - 3, -1) ⇒ ( 1, -3 )

( 2, - 1) ⇒ ( 1, 2 )

Cindy typed 200 words in 5 minutes. At this rate, how many words can she type in 25 minutes?

Answers

If Cindy can type 200 words in 5 minutes, divide 200 by 5.
200/5=40, so 40x25=1000.

How many degrees does the minute hand of a clock travel in 1 minute? What angle does an hour hand travel in 1 min?

Answers

Answer:

Step-by-step explanation:

The movement of the minute hand of the clock is circular. This means that a complete movement of the minute hand of the clock is the same as the angle formed at the center of the circle. The sum of the angles at a point is 360 degrees. The minute hand travels 360 degrees in a 60 minutes. It means that the degrees travelled in a minute is

360/60 = 6 degrees

The hour hand travels 360 degrees in 60 minutes. Therefore, the angle that the hour hand travels in 1 minute is

360/6 = 6 degrees

Final answer:

The minute hand of a clock travels 6° in 1 minute. The hour hand travels 0.5° in 1 minute.

Explanation:

To answer this question, we first need to consider what a full rotation is. A complete circle, one full rotation, is 360°. The minute hand of a clock completes one full rotation, or 360°, every hour or 60 minutes.

In 1 minute, the minute hand would have covered 1/60 of a full rotation. To calculate this in degrees, we multiply 360° by 1/60, which gives us 6°. Therefore, the minute hand of a clock travels 6° in one minute.

The hour hand moves more slowly. It takes 12 hours to complete a full rotation or 360°. In 1 minute, the hour hand covers, 360° divided by (12 hours x 60 minutes), which gives us 0.5°. Therefore, the hour hand of a clock moves 0.5° in 1 minute.

Answer:

A) The vertex of CDH would be point D.

B) The sides of CDH would be CD & HD.

C) Classify CDH as an acute angle.

Step-by-step explanation:

A) Those are just where they meet in the middle, and D is the middle point of CDH.

B) Those are literally just the sides.

C) There's acute, obtuse, right etc. angles. Acute angles are less than 90 degrees. And your angle is definitely less than 90.
