T 73 73 70 68 73 80 86 89

Answer 2

for b. does this sound right? T'(8) means how fast T is changing at t=8, in °F/hr.

Answer 3

"T'(8) means how fast T is changing at t=8, in °F/hr" is correct.

as for a, use the values of T at t=6 and 8 to get an average of T' between t=6 and 8;
recalculate the average of T' between t=8 and 10 with the T values respectively.

Average T' at 8 will be the average of the above two numbers....

Answer 4

(T(8)-T(6))/2= 5/2
(T(10)-T(8))/2= 7/2
