66/55 in simplest form is 6/5. Because...
66÷ 11= 6
55÷ 11= 5
The slope of the line is -2/5x
Cos(2 arctan(4/3)) = cos(2 arccos(3/5)) = cos^2(arccos(3/5)) - sin^2(arccos(3/5)) = cos^2(arccos(3/5)) - sin^2(arcsin(4/5)) = (3/5)^2 - (4/5)^2 = 9/25 - 16/25 = -7/25.
3/4 or 0.75 hope this helps :)
Answer:
$1917.60
Step-by-step explanation:
Interest = Principal x Rate x Time
103.55 = (.05)(13/12)P
103.55 = .054P
P = 1917.60
