Answer(Find the Linearization at h=5): 
The answer is on the paper
Step-by-step explanation:
80:100=x:20
x=80×20/100=16
21=5+2+5+2+5+2
So their are 6 orange picks
For this case we have the following expression:

We must evaluate the expression when:

Substituting the values we have:

Equal signs are added and the same signs are placed.

Different signs are subtracted and the sign of the major is placed:

Finally we have to:
