Which choice shows the image of triangle QRS after the reflection over the x-axis followed by a rotation of 180° around the orig
in?
1 answer:
Answer:
A
Step-by-step explanation:
We see that triangle QRS is located in Quadrant III. (See attachment for labelling of quadrants)
Reflecting it over the x-axis means that we flip it over the x-axis, or we flip it vertically. Doing so, QRS will end up in Quadrant II.
Now, we need to rotate QRS 180 degrees about the origin. The quadrants are all 90 degrees away from each other, which means that if we rotate QRS about the origin 180 degrees, we'll end up two quadrants away from Quadrant II: we'll end in Quadrant IV.
Look at each of the answer choices. The only choice that features Q'R'S' (the image of QRS) in the fourth quadrant is the first choice, or A. So that's the answer.

<h2>Hello!</h2>
The answer is:
The airplane will travel 8800 feet in 10 seconds.
<h2>Why?</h2>It's a conversion exercise, we need to be careful in order to solve it with no mistakes.
First:
We need to remember that 1 hour is equal to 60 minutes, and 1 minute is equal to 60 seconds, so, to calculate how many seconds are in one hour, we need to perform the following operation:
Second:
We need to convert from miles to feet, we need to remember that 1 mil is equal to 5280 feet.
So, solving we have:
Now, calculating how many feet does it travel in 10 seconds, we have:
We have that the airplane will travel 8800 feet in 10 seconds.
Have a nice day!
