F(x) = ln (6-x); find the domain.
The domain of the "ln" function is (0, infinity), or "x is greater than zero."
Thus, the domain of the given function is "(6-x) is greater than zero."
Solve this: 6-x > 0. Add x to both sides. Then 6 > x, or x < 6 (answer)

Answer:
Step-by-step explanation:
A destroyed angle is called to as a rect-angle.
It's a pun on the "wreck"tangle
Under C, I believe. When we have the same base (2 in this case), 2^1/4*2^1/4 can be written as 1/4+1/4 since it’s the same base. And 1/4+1/4+1/4+1/4 is 4/4 and that is 1 so 2^1 is 2.
Answer:
B. 31°, 106°, and 43°.
Step-by-step explanation:
the sum of the measures of the angles in a triangle add up to 180°, so:
3x+1+11x-4+5x-7=180
19x-10=180
19x=190
x=10
now that we know x is equal to 10, we can find the three angle measures:
3x+1 -> 3(10)+1 = 31°
11x-4 -> 11(10)-4 = 110-4 = 106°
5x-7 -> 5(10)-7 = 50-7 = 43°
so, the answer is B.
