Answer:
do your self it is easy
Step-by-step explanation:
do your self it is easy
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

They all look right but i'm not sure about the last one?
Step-by-step explanation:
He lived 9 months in Portugal and 5 months in Brazil. This is because 130*9 + 150*5 = 1920.
P(Q|R) = P(Q&R)/P(R)
= (3/37)/(7/37)
= 3/7
The appropriate choice is ...
B. 3/7
