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:
(b)
Step-by-step explanation:
Given: Cost of car is
Sales tax is
The license and title charges are
To find: The amount that the credit union will finance.
Solution:
We have,
Cost of car
Sales tax is of
Therefore,
sales tax
The license and title charges
Now, the amount that the credit union will finance is
cost of carsales tax
the license and title charges
Hence, the amount that the credit union will finance is .
So, (b) is correct.
