A)
i) C(n)=42n
ii)C(n,x)=15n+0.25x
b)She plans to drive a total of 600 Km, therefore: x=600
Budget: C(n)=42n
Deluxe: C(n,x)=15n +0.25(600)=15n+150
Cost of Budget< Cost of Deluxe
42n<15n+150
42n-15n<150
27n<150
n<150/27
n<5.5 ⇒n<5
Answer: The maximum number of days would be 5 days.
Answer:
Actually, the graphs of functions defined by y = sin x are called sine waves or sinusoidal waves. Notice that the graph repeats itself as it moves along the x-axis. ... This graph repeats every 6.28 units or 2 pi radians. It ranges from -1 to 1; half this distance is called the amplitude. The purpose is :Triangulation a process that works by using the distance from two known points, is used in cell phones equipped with GPS. A GPS receiver measures distance using the travel time of radio signals from satellites. Sine and cosine functions are used to find the location and distances in the GPS system of the cell phone.
