Answer: Straight north-south road in this scale is 4.55 miles long.
Step-by-step explanation:
Since we have given that
1 inch = 1000 feet
If a map of the city limits is 24 inches from North to South,
So, Length of straight north- south road in this scale is given by
So, Straight north-south road in this scale is 4.55 miles long.

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

The given compound inequality is
First we solve the first inequality,
Now we solve the second inequality
So we have
So the required solution is
Correct option is A .
