1.9 or 1 9/10
Glad I could help!
Note: The third term of the sequence should be
instead of
, otherwise the sequence has no common ratio.
Given:
The given sequence is

To find:
The common ratio of the given sequence.
Solution:
The quotient of each pair of consecutive terms are:

Similarly,


And,


Therefore, the common ratio of the given sequence is
or 0.75.
Answer:
a)
degrees
b) 
Step-by-step explanation:
An approximate formula for the heat index that is valid for (T ,H) near (90, 40) is:

a) Calculate I at (T ,H) = (95, 50).
degrees
(b) Which partial derivative tells us the increase in I per degree increase in T when (T ,H) = (95, 50)? Calculate this partial derivative.
This is the partial derivative of I in function of T, that is
. So



4/5 because look at the picture
