Answer:
11.6--------------------------------------
Explanation:
See the attached image for a visual reference
The distance from point D to E is 21 units. Point C is the midpoint, so CD is 10.5 units long (21/2 = 10.5)
We have a right triangle ACD. The legs are
AC = 5
CD = 10.5
The hypotenuse is
AD = x
Because AD is another radius of the same circle
Use the pythagorean theorem to find x
a^2 + b^2 = c^2
5^2 + 10.5^2 = x^2
25 + 110.25 = x^2
135.25 = x^2
x^2 = 135.25
x = sqrt(135.25)
x = 11.629703349613
which rounds to
11.6 when rounding to the nearest tenth (one decimal place)

Answer:
1354.106 rounds to 1354.1
Step-by-step explanation:
thousands hundreds tens ones. tenths hundredths thousands
1 3 5 4 . 1 0 6
We are rounding the 1 after the decimal so we look at the next digit
0<5 so we leave the 1 alone
1354.106 rounds to 1354.1
I’m not sure how to explain it but the answer is B
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, ∞).
