Answer:

1 hour and 12 minutes

Step-by-step explanation:

Let's say x = time it takes for the trains to be 204 miles apart.

Speed = Distance/Time,

Time = Distance/Speed,

x = 204/ (80 + 90) = 204/170 = 1 and 1/5 hours or 1 hour and 12 minutes

Answer:

A) f^-1(x)=(x-8)^3+2

Step-by-step explanation:

To find the function inverse, switch the x with y and solve for y.

$y=\sqrt[3]{x-2}+8 \\\\x=\sqrt[3]{y-2}+8\\\\(x-8)^3 = y-2\\\\ (x-8)^3 + 2 = y$
