We conclude that both functions f(x) and g(x) are positive on the interval (4, ∞)
<h3>
In which interval both functions f(x) and g(x) are positive?</h3>
On the image we can see two graphs, the blue one is the graph of f(x) and the red one is the graph of g(x).
A function is positive when its graph is above the horizontal line.
For the case of f(x), it is positive on the intervals:
(-∞, -2) and (1, ∞)
And for function g(x), we can see that it is positive on the interval:
(4, ∞)
Now, the interval where both functions are positive is in the intersection between the intervals (in this case is the smaller of the intervals, so it is the correspondent to g(x)), which is (4, ∞)
We conclude that both functions f(x) and g(x) are positive on the interval (4, ∞).

Answer:
The percentage of error in the question is 75%.
Step-by-step explanation:
To find the percentage of error, we need to subtract the actual value from the value that was expected, divide the result by the expected value.
He predicted that the crop would produce 8 bushels so this is our expected value. The actual value, which is the number of bushels produced, is 14.
- If we make the calculation (14 - 8) / 8 = 6 / 8.
- And then multiply the result by 100 to find the percentage, (6 / 8) x 100 = 75.
So the percentage of error in the question is 75%.

Answer:
2 1/4
Step-by-step explanation:
Answer:
225pi=a*9
divide both sides by 9
25pi=a
a=pir^2
25pi=pir^2
cancel out pi
25=r^2
so the length of the radius is 5
1. -34
2. x= 8; y= 3.(and 3 repeating)
