In order to find the inverse of a function,you always do this process. First you would right the normal equation out. After that,you switch the x and y terms around. Then you would solve like a normal 2-step or however many long equation. By flipping the x and y values,you get what the other variable creates
Answer:
Normally, Acceleration due to gravity is

or

Step-by-step explanation:
From the web
These two laws lead to the most useful form of the formula for calculating acceleration due to gravity: g = G*M/R^2, where g is the acceleration due to gravity, G is the universal gravitational constant, M is mass, and R is distance
Answer:
a). 18 minutes
b). 8.4 miles
Step-by-step explanation:
a). Let Luis meet Kristina after the time = h hours
So the distance traveled by Luis in h hours = Speed × time
= 8×h
= 8h miles
If Kristin started after 45 minutes of
hours then the distance traveled by her
= Speed × time
=
miles
Since after h hours distances traveled by Luis and Kristin are same so,

28h - 8h = 
20h = 21
h = 1.05 hours
So the time taken by Kristin = (h - 0.75)
= 1.05 - 0.75
= 0.30 hours ≈ 18 minutes
b). Distance traveled by Luis before Kristin catches Luis = 8×1.05
= 8.4 miles
