Answer:
9 hours
Step-by-step explanation:
12 times 3 is 40 so 3 times 3 is 9
Answer:
37.7; B, 36 pi; C
Step-by-step explanation:
Hello!
<u>The formula for finding circumference of a circle is 2πr:</u>
In that case, we can just substitute 6 meters for our radius.
6 × 2π = 12π
12 × 3.14 (about π) = 37.68
That's about 37.7 (when rounded.)
Thusly, the closest option is 
.
<u>The formula for finding the area of a circle is πr²:</u>
In that case, we can just substitute 6 meters for our radius. (again.)
6² = 36
36 × π = 36π
Therefore, 
is our answer.

Answer:
Vertex form is
where (h,k) is the vertex
So our vertex form is
It passes through (6,0) so we have
Solve for a.
So our equation is
1) An operator is missing in your statement. Most likely the right expression is:
2x
f(x) = -------------
3x^2 - 3
So, I will work with it and find the result of each one of the statements given to determine their validiy.
2) Statement 1: <span>The
graph approaches 0 as x approaches infinity.
Find the limit of the function as x approaches infinity:
2x
Limit when x →∞ of ------------
3x^2 - 3
Start by dividing numerator and denominator by x^2 =>
2x / x^2 2/x
--------------------------- = ---------------
3x^2 / x^2 - 3 / x^2 3 - 3/x^2
2/∞ 0 0
Replace x with ∞ => ------------ = ------- = ---- = 0
3 - 3/∞ 3 - 0 3
Therefore the statement is TRUE.
3) Statement 2: The graph approaches 0 as x
approaches negative infinity.
</span><span><span>Find the limit of the function as x approaches negative infinity:
2x
Limit when x → - ∞ of ------------
3x^2 - 3
Start by dividing numerator and denominator by x^2 =>
2x / x^2 2/x
--------------------------- = ---------------
3x^2 / x^2 - 3 / x^2 3 - 3/x^2
2/(-∞) 0 0
Replace x with - ∞ => ------------ = ---------- = ---- = 0
3 - 3/(-∞) 3 - 0 3
Therefore, the statement is TRUE.</span>
4) Statement 3: The graph approaches 2/3 as x approaches
infinity.
FALSE, as we already found that the graph approaches 0 when x approaches infinity.
5) Statement 4: The graph approaches –1 as x approaches negative infinity.
</span>
FALSE, as we already found the graph approaches 0 when x approaches negative infinity.
