Answer:
B. 4
Step-by-step explanation:
The given function is of the form:

A is called the amplitude of the given function.
We can read from the graph that, the function ranges between:
-4 and 4
This implies that:

Therefore the amplitude of the function is 4.
Hence the value of A must be 4.
Add 0.1 to 0.0(54) to get 0.1(54).
Answer:
2
Step-by-step explanation:
Use order of operations PEMDAS
3^2 = 9 * 2 = 18
20-18= 2
0, 1/2, -53, and 0.433 all belong in rational category
