Answer:
2. Unit rate: 36/3 = $12
3. $36 for 3 tickets
Bkz 25/2 = 12.5 vs 26/3 = 12
In place of t, or theta, I'm going to utilize x instead. So the equation is -3*cos(x) = 1. Get everything to one side and we have -3*cos(x)-1 = 0
Let f(x) = -3*cos(x)-1. The goal is to find the root of f(x) in the interval [0, 2pi]
I'm using the program GeoGebra to get the task done of finding the roots. In this case, there are 2 roots and they are marked by the points A and B in the attachment shown
A = (1.91, 0)
B = (4.37, 0)
So the two solutions for theta are
theta = 1.91 radians
theta = 4.37 radians
Answer:
Part A: 40% are pennies
Part B: NIckels 10, Quarters 20, Pennis 20
Answer:
