Answer:
Geometric Mean = 9.17
Step-by-step explanation:
Here,
a = 7
b = 12
Geometric mean = root(ab)
= root( 7 x 12)
= root(84)
= 9.17
Option B i.e. Non-Euclidean
Answer:
1 to 5
211 to 1500
11 to 300
Step-by-step explanation:
1.8 to 9 = 18/90 = 1(18)/5(18) = 1/5 = 1 to 5
2.11 to 15 = 211/1500 = 211 to 1500
3.30 to 90 = 330/9000 = 110/3000 = 11/300 = 11 to 300
Answer:

Step-by-step explanation:
You need to apply the chain rule here.
There are few other requirements:
You will need to know how to differentiate
.
You will need to know how to differentiate polynomials as well.
So here are some rules we will be applying:
Assume 




Those appear to be really all we need.
Let's do it:






I tried to be very clear of how I used the rules I mentioned but all you have to do for derivative of natural log is derivative of inside over the inside.
Your answer is
.
