Alake near the arctic circle is covered by a sheet of ice during the cold winter months. when spring arrives, the ice starts to melt. s(t)s(t) models the ice sheet's thickness (in meters) as a function of time tt (in weeks). s(t)=-0.25t+4s(t)=−0.25t+4 by how much does the sheet's thickness decrease every 66 weeks?

1.5 meters

Step-by-step explanation:

Given: A lake near the Arctic Circle is covered by a sheet of ice during the cold winter months. S

S(t) models the ice sheet's thickness (in meters) as a function of time t (in weeks)

if we put x=0, then

So 4 meters is the initial thickness

To find the thickness after 6 weeks, put x=6 we get

Decrease in thickness every 6 weeks=
