This is a simple equation.
The equation is y = 1.6x with y being the miles and x being the kilometers.
Lets plug the kilometers in.
Y=1.6(7.7)
1.6 * 7.7 = 12.32
12.32 miles is equal to 7.7 kilometers
HOWEVER
There are about .6 miles in a kilometer, so if you typed this wrong I don't know.
It is still the same concept.
Y = .6x
Y = .6(7.7)
.6 * 7.7 = 4.8
In this case there are 4.8 miles in 7.7 kilometers
Multiply first then you would wanna add but you can't until you subtract 5-3 then add I got 12
Given:

To find:
The f'(y).
Solution:
Chain rule of differentiation:
![[f(g(x))]'=f'(g(x))g'(x)](https://tex.z-dn.net/?f=%5Bf%28g%28x%29%29%5D%27%3Df%27%28g%28x%29%29g%27%28x%29)
Differentiation of exponential:

We have,

Differentiate with respect to y.



Therefore, the differentiation of the given function is
