Answer:
67.2
Step-by-step explanation:
You take 100 and minus 32.8
it is the same as 10minus 8 is 2 so we right the 2. then 9-2 is 7. and 9-3 is 6
99.(1)0
-
32.8
---------------
67.2
45/X + 63/X= 108/X = Y, X= 108 divided by 2 = y, y=54
To find the number of years between 1844 to 2015 you have to subtract.
Lets say that x is the # of years in between 1844 and 2015
Then we have:

After doing the subtraction using a calculator or a pencil and paper, you get that:

So 171 years have passed from 1844 to reach to 2015.
Answer:
π
Step-by-step explanation:
The *period* of a function is the length it takes before it repeats. Usually, the period of the sine function is 2π; it takes a full rotation around the unit circle for it to repeat. When we replace the input x with -2x, this does a few things:
- Changes the rotation direction
- Makes the rotation go twice as fast
If we rotate around the unit circle twice as fast, it’ll take us half of 2π, or just π to complete a cycle.
