For convenience sake, I will be omitting the arguments of the trig functions.
- cos²/sin² + (cos)/(sin)
- = cos²/sin² + (cos sin)/sin²
- = (cos² + cos sin)/(sin²)
Answer:
im looking at B! hope this helps!
Step-by-step explanation:
Answer:
an = -6 + n
a10 = -6+ 10 =4
Step-by-step explanation:
an should start at one behind the first number so it should be -6. Then we add whatever the sequence is increasing by, which is 1 in this case, multiplied by n.
an = -6 + n
a10 = -6+ 10 =4
In mathematics, a square number or perfect square is an integer that is the square of an integer; in other words, it is the product of some integer with itself. For example, 9 is a square number, since it can be written as 3 × 3. 16 is a perfect square and 10 is not a perfect square
The decay factor is 0.95<span> because this is </span>95%<span> as a decimal. Just think of how much you need to make up 100% and convert to a decimal. I'd be happy to explain more about how this relates to the exponential decay function y = a(1-b)^x, but I don't want to ramble on</span>
