Problema Solution
after 2 hours of snowing, there was 2.5 inches of snow, after 6 hours there was 14.3 inches of snow. what is the equation? how much snow was on the ground if it snowed for 11 hours?
Answer provided by our tutors
t = time (hours)
y = inches of snow
Use point-slope forumula to find the equation: slope = (14.3 - 2.5)/(6 - 2) = 2.95
y - 2.5 = 2.95(t - 2)
y - 2.5 = 2.95t - 5.9
y(t) = 2.95t - 3.4
After 11 hours: y(11) = 2.95(11) - 3.4 = 29.05 inches of snow.
