Answer:
That is the solutions are:
,
Step-by-step explanation:
The period of 
or 
is 
.
Let's look at the first rotation to see when 
happens.
This happens at 
and also at 
. (Notice I just looked at the x-coordinates because that is what cosine is. Sine is the y-coordinate.)
Now to find the rest of the solutions we can just make full rotations either way to get back to those points .
That is the solutions are:
Y=2 7x2= 14
X= 7 4x7=28
28-14=14
Answer:
B. No
Step-by-step explanation:
-A right angle triangle has two complimentary acute angles and one right angle.
-
is usually one of the acute angles and is equivalent to 90º minus it's complimentary acute angle.
-Complimentary angles add up to 90º.
#For complimentary angles:
The two acute angles cannot have the same Cosine value.
Hence, she's not correct.
That mixed decimal is equal to 1,024,242,424/1,000,000,000 . (You may certainly reduce it to lower terms if you like.) / / / If you had said that the '24' repeats forever and never ends, then it would have been 338/330 . (You're free to simplify that one too.)
