Because angle B is the largest angle. AC is the largest side.
In a triangle, the largest angle opposes the largest side.
For all <em>x</em>,
sin²(<em>x</em>) + cos²(<em>x</em>) = 1
so we have
(1 - cos²<em>A</em>) csc²<em>A</em> = sin²<em>A</em> csc²<em>A</em>
and since csc(<em>x</em>) = 1 / sin(<em>x</em>), so the expression reduces to 1.
Y = 18(1.15)x is the answer
After one year
18×(1.15)=20.7
After two years
18×(1.15)^(2)=23.81
Answer:
see below
Step-by-step explanation:
The domain is the possible x values
For the top graph x goes from 0 to 240
0 ≤x≤240
For the bottom graph the domain is from -3 but not including -3 because of the open circle to 6
-3 < x ≤6
(-3,6]
The range is the possible y values
The lowest value of y is -5 and the largest is 7
-5 ≤y≤7
[-5,7]
