Answer:
We know
sin (A + B) = sin A cos B + cos A sin B
sin (A - B) = sin A cos B - cos A sin B
(A + B) + sin (A - B)
= sin A cos B + cos A sin B + sin A cos B - cos A sin B
= sin A cos B + sin A cos B
= 2 sin A cos B
The answer is D you cannot factor the given polynomial
Answer:
Step-by-step explanation:
- Initial percentage = 31%
- Average increase of percentage = 2.6% per year
<u>This can be represented as:</u>
y- percentage after x years, x - number of years after the first year
4 4/5 you make the whole number a fraction by putting a 1 under it and the multiply like normal then make it into a mixed number<span />
