Simplify the trigonometric expression.
Call the expression E:
So basically E is equivalent to
where the sign depends on which quadrant
lies. Shortly,
I hope this helps. =)

The answer is 6 because anything to the power of 1/2 is the square root of it
Answer:
1 hour after they leave
Step-by-step explanation:
The distance each travels is proportional to its speed. The given speeds are at right angles to each other in a 5:12 ratio. The Pythagorean theorem tells you the hypotenuse of such a right triangle will have length ...
√(5²+12²)=√169 = 13
That is the speeds are in the ratio 5:12:13, where 13 represents the relative separation speed. Actual speeds are then 50 mph : 120 mph : 130 mph.
So the distance between the boat and steamer will be increasing at 130 mph. The distance will be 130 miles after 1 hour.
Answer:
15.12
Step-by-step explanation:
4.20 x 3.60 = 15.12
Answer:
1/3
Step-by-step explanation:
The two points are (3,0) and (-3, 2).
Slope is y change over x change.
So... 2-0 over -3-3 which is -2 over -6.
Simplified is 1/3
Hope this helps :D
