Form a union for the following sets. K = {2, 3, 5, 8} L = {3, 5, 7}

Kisachek [45]

A union for sets means you combine the two sets together. The symbol of a union is ∪, so we can represent this question with K ∪ L.

You simply must combine the two sets together without repeating any of the same numbers.

K ∪ L = {2, 3, 5, 7, 8}.

A ship sailing parallel to shore sights a lighthouse at an angle of 14° from its direction of travel. After traveling 4 miles fa

timama [110]

Answer:

C. 6.19 mi

Step-by-step explanation:

The angle between the two ship locations as viewed from the lighthouse is ...

23° -14° = 9°

This is opposite the known side of the triangle: 4 miles. The unknown side, the distance to the lighthouse from the second position, is opposite the 14° angle in the triangle. The Law of Sines can be used to find the distance (d) of interest:

d/sin(14°) = (4 mi)/sin(9°)

d = (4 mi)(sin(14°)/sin(9°)) ≈ 6.1859 mi

The ship is 6.19 miles from the lighthouse at the second sighting.

$f(x)=\frac{(lnx)^2}{2x};\ D_f:x\in\mathbb{R^+}\\\\use:\left[\frac{f(x)}{g(x)}\right]'=\frac{f'(x)g(x)-f(x)g'(x)}{[g(x)]^2}\\\\f'(x)=\frac{[(lnx)^2]'\cdot2x-(lnx)^2\cdot(2x)'}{(2x)^2}=(*)\\\\\ [(lnx)^2]'=2lnx\cdot\frac{1}{x}=\frac{2lnx}{x}\\\\(2x)'=2\\\\(*)=\frac{\frac{2lnx}{x}\cdot2x-(lnx)^2\cdot2}{4x^2}=\frac{4lnx-2(lnx)^2}{4x^2}=\frac{[4lnx-2(lnx)^2]:2}{4x^2:2}=\frac{2lnx-(lnx)^2}{2x^2}$
