Tan(3x) = 1
3x = arctan(1) = pi/4, -3pi/4
x = (pi/4)/3 = pi/12 or (-3pi/4)/3 = -pi/4
Therefore, x = pi/12 or -pi/4
For > and < the circle is open, for greater than or equal to and less than or equal to the circle is closed
You have a rectangle and 2 triangles:
rectangle = 12 *6 = 72
larger triangle on left, find the base:
base = 6 / tan(45) = 6
area = 1/2 x b x h = 1/2 x 6 x 6 = 18
smaller triangle:
area = 1/2 x b x h
1/2 x 2 x 6 = 6
total area:
72 +6 +18 = 96 cm^2
The answer is C. 1/2
Hope this helps!
Answer:
True
Step-by-step explanation:
The definition of the function is a relation with exactly one x for each y. x is the domain, and y is the range, so all functions have a domain and a range.
