We have:
Then we use trigonometric identities to change the negative sign of the trigonometric functions, so:
We clear f(x):
we simply what we can:
Thus, the correct answer is;
It will be D!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
Yes, Fiona is correct
Step-by-step explanation:
WHen the pythagorean theorem is applied to the side lengths (2^2 + 4^2 = c^2), the result for c^2 is 20. The correct answer would be sqrt.20. But Fiona is also correct becuase sqrt of 20 can be simplified to sqrt.4 * sqrt.5; which equals 2*sqrt.5
22% in fraction form is 
or 0.22, but it isn't the simplest form.
To put into a simplest form, you must divide the numerator <em>and </em>the denominator by a common multiple.
or 0.22 is divisible by 2. Therefore, you can divide by 2.
Equation:
divided by 
= 
Hence your answer,
Hope this helps!
