Answer:
The radius of convergence is half of the length of the interval of convergence. If the radius of convergence is R then the interval of convergence will include the open interval: (a − R, a + R). To find the radius of convergence, R, you use the Ratio Test.
You can rearrange f(x) as:
f(x) = 3(x^2 + 3x) + 12 = 3(x+1.5)^2 +5.25
So you can see the vertex is at (0,5.25) when x = -1.5
The axis of symmetry then lies in x = -1.5
Answer:
I think it is 4, 14?
Step-by-step explanation:
Answer:
1.6 inches per hour. you would divide 4.8 by 3 which is equal to 1.6.
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
1/12 - 5/6 = -9/12
We need to get a common denominator of 12
1/12 - 5/6*2/2 = -9 /12
1/12 - 10/12 = -9/12
Since the denominators are the same, we can subtract the numerators
1-10 = -9
-9/12 = - 9/12
We can simplify -9/12 by dividing the top and bottom by 3
-9/3 = -3
12 /3 = 4
-9/12 = -3/4
