You have not provided the options to help us give you a specific answer.
If a quadratic function is written in the form
Then (h,k) is the vertex, and 'a' is a constant.
For instance
has vertex at (2,3).
Also, an absolute function in the form
has vertex at (h,k).
This means
also has vertex at (1,3).

Answer:
The factored form of x^3 -1 will be:
Step-by-step explanation:
Given the expression
Rewrite 1 as 1³
Thus, the factored form of x^3 -1 will be:
Answer:
x = 10 , 45 degrees.
Step-by-step explanation:
This seems a tricky one .
I guess we can use sin A + sin B = 2 sin (A+B)/2 cos (A - B) / 2
so sin 5x + sin x = 2 sin 3x cos 2x so our equation becomes
2 sin 3x cos 2x - cos 2x = 0
cos 2x ( 2 sin 3x - 1) = 0
so 2 sin 3x = 1
sin 3x = 1/2
giving 3x = 30 degrees and x = 10 degrees
or cos 2x = 0
so 2x = 90
giving x = 45 degrees.
