Answer:
a = π n for n element Z
Step-by-step explanation:
Solve for a:
sec(a) + tan(a) = sec(a) - tan(a)
Subtract sec(a) - tan(a) from both sides:
2 tan(a) = 0
Divide both sides by 2:
tan(a) = 0
Take the inverse tangent of both sides:
Answer: a = π n for n element Z

Answer: C an equilateral triangle
Step-by-step explanation:
Step-by-step explanation:
y = 5/x+6
y = 5/x stretches out the graph by 5 times. It increases and decreases 5 times more.
y = 5/x +6 makes your raises your graph 6 units higher.
15 + 0.75x = 57
-15 -15
0.75x = 42
0.75x/0.75 = 42/0.75
x = 56 people
The student interviewed 56 people on the day he earned $57
