Math Problem

Question

The time, t, in minutes, needed for clothes hanging on a line outdoors to dry, at a specific temperature, depends on the humidity, h. The time can be approximated by the equation t equals 2 h squared plus 90 h plus 30, where h is the humidity expressed as a decimal number. Find the length of time required for clothing to dry if there is 40% humidity

Answer 1

T(h) = 2*h^2 + 90h + 30

 

T(0.4) = 66.32

 

 1 hour 6 minutes 19.2 seconds
