The answer is communicative
This is just a notation thing, once you understand it this becomes easy.
Let's say h(x) = 2x. In this case we know things like h(2) is 2(2) which is 4. Note that we can also input other variables. In fact this is the very manner in which defined the function. If h(x) = 2x than h(y) = 2y.
Now we try defining a variable, let's use u as something. let's say u = 32x+7. We already know h(u) = 2u. Now substitute in u, and we find h(u) = 2(32x+7). If we rewrite u in function notation we can write this as h(u(x)) = 2(32x+7). Basically what we've done here is we put one function inside another function.
This is the notation part. h(u(x)) can be rewritten as (h o u)(x).
And that's all there is to it!
Answer:
B 1/9
Step-by-step explanation:
Because there are 6 sides of a die then your adding 3 to the 6
I think. (please dont hate me if im wrong!!)
You can inscribe a quadrilateral inside a circle if and only if its opposite angles are supplementar. In your case, this means that
Since we're interested in the angle R, let's use the second part of the equalities above to substitute the given values for R and P:
The left hand side can be simplified to , so if we subtract 8 from both sides the equation becomes
Since , we can compute the angle R by plugging this value into its formula:
