Hello!
The graphs of sine and cosine are waves. Therefore, choice A and B are wrong.
The graph of f(x) = cot(x) is an inverse of f(x) = tan(x), so therefore the graph of f(x) = cot(x) has the lines similar to the graph above, but it's flipped.
So therefore, the graph shown above is choice C, f(x) = tan x.
Answer:
n = 11/3
Step-by-step explanation:
n = certain number
6n - 1 = 21
6n = 22
n = 22/6 or 11/3
Just put each number in different positions.
425
542
254
All of these numbers are different and use the same 3 digits
Answer: 30 pounds
Step-by-step explanation:
Let the weight 3 month ago be X.
20% more than x is:
1.2x
We now have the following equation:
1.2x = 36
x = 36/1.2
x = 30 pounds
Hope that helps! Have a good day :)
