Answer:
B. 10
Step-by-step explanation:
These are vertical angles meaning they are also equal.

Answer:
By translating the function cos(x) 90 degrees to the right.
Step-by-step explanation:
The sine function is just the cosine function translated 90 degrees to the right. You can see the visualization below. They overlap.
If you're wondering why the diagram shows a shift in

That's just the equivalent to 90 degrees in radians.
The answer is 0.008a^3 because you would do 0.2 to the power of 3
A rectangle has two dimensions, width and length, and the area of it is their product.
since we know its area is 3x²-11x-4, then the two factors from that trinomial are the likely width and length, namely (3x + 1) (x - 4).
you can check them with FOIL.
