Simplify the equation: x(pie)+7893
Answer:

or 10.39 rounded
Step-by-step explanation:
a²+b² =c²
6²+b²= 12²
36+b² = 144
-36 -36
b² = 108

F(n)=9n
f(10)=9(10)
f(10)=90
f(10)=90 means that when you work 10 hours your gross pay is $90.

Answer:
5.375 in. to the nearest thousandth.
Step-by-step explanation:
Area of a regular heptagon
= 7/4 * cot(pi/7) * s^2 where s is the length of one side.
105 = 7/4 * cot(pi/7) * s^2
s^2 = 105 / (7/4 cot (pi/7)
= 28.8945
s = sqrt 28.8945
= 5.375 in.
