Equation: 99 + 45x, with x as how many ever months.
After five months:
99 + 45(5) = 99 + 225 = $324.
Divide the nonagon radially into 9 congruent, equilateral isosceles triangle. Each triangle has vertex angle of 360°/9 = 40°.
Interior angle of polygon = 180°-40° = 140°.
Sum of interior angles = 9(140°) = 1260°
Answer:
C
Step-by-step explanation:
1/4--1/2=0.75
This is less than 2 which you get from 1/2 times 2 which =1
1+1=2
You know when it is a periodic function if the values repeats in regular intervals or periods. An example of this is trigonometric functions that repeat over intervals of 2 pi radians.
