The amount of airborne particulate pollution p from a power

The amount of airborne particulate pollution p from a power plant depends on the wind speed s, among other things, with the relationship between p and s approximated by p = 49 - 0.01s^2. Find the value(s) of s that will make p = 0. (Enter your answers as a comma-separated list.) What value of s from part (a) makes sense in the context of this application? What does p = 0 mean in this application? p = 0 means there the particulate level is at

Solution

a)
p = 49 - 0.01*s^2
0 = 49 - 0.01*s^2
s= +70 or s=-70

b)
s is wind speed and it can\'t be negative
so,
s = 70

c)

particle level is at 0
