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

Answer:
5 x 4= 20
Step-by-step explanation:
5,10,15,20 its 20 5 x 4= 20
To determine the equation of the line, we use the point slope form equation for this problem. It is expressed as:
y - y1 = m(x - x1)
We substitute the given values in the problem to the equation.
y - 2 = -5(x - 2)
y = -5x +10+2
y = -5x +12
