The difference of the distances traveled by the comets for any given number of minutes is 25t.
Since the first comet travels at a speed of 30,000 miles per hour, the distance it travels in t minutes is d = 30000 mph × 1 h/60 min × t = 500t miles.
Also, the second comet travels at a speed of 28,500 miles per hour, the distance it travels in t minutes is d' = 28,500 mph × 1 h/60 min × t = 475t miles.
So, the difference in the distances traveled by the comets D = d - d'
= 500t - 475t
= 25t
So, the difference of the distances traveled by the comets for any given number of minutes is 25t.

3/(x-1) - 1/(x^2-1) = 5/(x-1)
Subtract 3/(x-1) from both sides
-1/(x^2-1) = 2/(x-1)
Factor x^2 - 1
-1/[(x-1)(x+1] = 2/(x-1)
Multiply by (x-1)(x+1) on both sides
-1 = 2 (x+1)
-1 = 2x + 2
Subtract 2 from both sides
-3 = 2x
Divide by 2 on both sides
-3/2 = x
The formula to find the circumference of a circle is :
To find the radius we would divide 3.3 by 2
The radius is always HALF of the diameter.
3.3/2=1.65
Now we know r=1.65
So we plug that into the circumference formula:
pi=3.14
Once you multiply all the numbers together you get:
C=10.36m
F(x) = 4x + 1
g(x) = x² - 5
(f - g)(x) means subtracting g(x) from f(x). So we can write:
So option c is the correct answer
