Answer:
y = 12,000x + 40,000
Explanation:
A linear relationship that would model the mileage of the car in this example is:
where
y is the number of miles
x is the number of years
m is the number of miles driven per year
q is the number of miles already in the car at x=0
In this problem, we have
m = 12,000 (number of miles driven per year)
q = 40,000 (number of miles already in the car at x=0)
So substituting into the equation we get
We can solve the problem by using Snell's law:
where
is the refractive index of the first medium (in this case, air, so 
)
is the refractive index of the second medium (in this case, water, so 
)
is the angle of incidence of the light, with respect to the vertical, so 
is the angle of refraction of the light inside the water, with respect to the vertical
Re-arranging the equation and using the data of the problem, we can find the the angle of refraction of the light inside the water:
where
