Answer:
3/(x +1) -4/(x +1)^2
Step-by-step explanation:
The partial fraction expansion will be of the form ...
A/(x+1)^2 +B/(x+1)
We can find the values of A and B by writing the sum of these terms:
= (A +B(x +1))/(x +1)^2
Then we require ...
B = 3
A +B = -1 ⇒ A = -4
So, the desired expansion is ...
3/(x +1) -4/(x +1)^2
Answer:
Step-by-step explanation:
Let
x -----> the wind speed in mi/h
y ----> the wind chill in °F
we have
so
For x=38 mi/h
substitute in the linear equation and solve for y
