Replace N with 6
6(6+1)(2(6)+1) / 6
(6*7*13) / 6

Step-by-step explanation:
X = 5. Using the pythagreom theorem, a²+b²=c², to solve x we put in the numbers into the equation getting a²+12²=13². Then solve for a. a²=25, 5·5=25, a=5 which means x=5.
Answer:
y = 3sin(πx/7) - 2
Step-by-step explanation:
Max swing is 1 - (-5) = 6, so A = 6/2 = 3
wave is shifted down two units, so C = -2
y = -2 when x = 0 so sine wave is a good choice as sin0 = 0
Wavelength is 14 units so k = 2π/14 = π/7
