Answer:
b = 1
Step-by-step explanation:
8 = b - 1 + 8b
<em>combine like terms</em>
8 = 9b - 1
<em>add 1 to both sides of the equation</em>
<em>8 + 1 = 9b - 1 + 1</em>
<em>8 + 1 = 9b</em>
9 = 9b
<em>divide both sides of the equation by 9</em>
9/9 = 9b/9
1 = b

It is discovered using its notion that the domain and range of the function are given by (C) D: [–4, ∞) and R: [0, ∞).
<h3>
What are the domain and range of a function?</h3>
- The domain of a function is the set of values that can be plugged into it. This set contains the x values in a function like f(x).
- A function's range is the set of values that the function can take.
- This is the set of values that the function returns after we enter an x value.
To find the domain and range:
- The given function in the problem is:

- Because the square root function does not exist for negative numbers, the domain is denoted by:
≥
→
≥ 
- Therefore, it is discovered using its notion that the domain and range of the function are given by (C) D: [–4, ∞) and R: [0, ∞).
- The range of the square root function is
≥
, which remains the same as there are no vertical translations.
Therefore, it is discovered using its notion that the domain and range of the function are given by (C) D: [–4, ∞) and R: [0, ∞).

(C) D: [–4, ∞) and R: [0, ∞)
(D) D: (4, ∞) and R: (–∞, 0)
Answer:
12.56 (13 if rounded)
Step-by-step explanation:
A=pi x r squared
A=2 squared multiplied by pi
A=4 times pi
plug into calculator should be about 12.56
