A. Reflection over y = 2
B. Reflection over y axis, reflection over y = 1
C. I'm guessing you just have to draw this one, just put the center on (2,0) and enlarge it by the scale factor
Answer:
C. Multiply 3 by 18
Step-by-step explanation:
Further explanation

Perhaps we can treat this as a "distance to horizon" problem, the observer is 7 mi above the earth
One formula is: d+=+sqrt%28%283h%29%2F2%29 where d is in miles and h is in feet
Change 7 mi; 5280*7 = 36960 ft
so we have
d = sqrt%28%283960%2A3%29%2F2%29
d ~ 235.5 mi
looking in opposite directions a total of 2*235 = 471 mi can be viewed
Find the circumference of the earth
C = pi%2A8000
C = 25133 mi
:
The arc: 471%2F25133 * 360 = 6.7 degrees
:
This should be pretty close, because the earth is so large compared to the altitude. would appreciate if it you would let me know. C
Answer:
The answer is 24/<u>2</u>=<u>36</u>/3=<u>66</u>/5.5=108/<u>9</u>=<u>180</u>/15.
Step-by-step explanation:
Given:
24/2=_/3=_/5.5=108/_=_/15.
Now, we need to solve this by putting
in the place of _ and then continue:

<em>By</em><u><em> cross multiplication we get:</em></u>

By dividing with 2 we get:

Now, <u><em>we will continue like this process:</em></u>



And, then again:



And, last:



Therefore, the answer is 24/<u>2</u>=<u>36</u>/3=<u>66</u>/5.5=108/<u>9</u>=<u>180</u>/15.
