Time taken to rotate 90° is 13 seconds
<u>Explanation:</u>
Given:
To complete one revolution, the searchlight takes 52 seconds
One revolution = 360°
So,
360° is completed in 52 seconds
Time taken to complete 90° is 
= 13 sec
Therefore, time taken to rotate 90° is 13 seconds
The answer is "53.33 yards"
Answer:
1. (4,6)
2. (-1, 8)
3. Not enough information given.
Step-by-step explanation:
1. Reflecting the point over the y-axis will place the point (-4,6) 4 units on the other side of the axis. This would place it at (4,6) without changing the y-coordinate.
2. Reflections across the line y=x means y and x trade places. This will result in the point (8,-1) becoming (-1,8).
3. Not enough information about the shape is given. Need to know where it is now to know where it will go.
