Answer:
It's exponential function, the base is 5.
Horizontal asymptote is y = 0
At x = 0, y = 3
x = 1, y = 15
Step-by-step explanation:
By applying the law of sines, the length of side PQ is equal to 7.1 units.
<h3>What is the law of sines?</h3>
The law of sines is also referred to as sine law and it can be defined as an equation that relates the side lengths of a triangle to the sines of its angles.
<h3>How to calculate the length of PQ?</h3>
Mathematically, the law of sines is given by this equation:

Substituting the given parameters into the formula, we have;

PQ = 7.1 units.

Total distance covered = 5 x 30 = 150 miles
Angle of travel with respect to south pole = 180 - 164°56' = 15°4'
Let the distance southwards covered be x, then
cos 15°4' = x/150
Thus, x = 150 cos 15°4' = 144.84
Therefore, the distance covered southwards = 145 miles to the nearest mile.
