Total Change Theorem
During a 40-minute workout, a person riding an exercise
machine burns calories at a rate of c calories per minute,
30
where the function y = c(t) is given in the figure to the
left. On the interval 0 <t< 10, the formula for c is
25
c(t) = -0.05t2 +t+ 10, while on 30 <t< 40, its
20
formula is c(t) = -0.05t2 + 3t – 30.
15
Which part of the expression do you need to use to find
the total calories between from t= 10 to t = 30?
10
5
O c(t) = -0.05?
+t+ 10
20
30
O c(t) = -0.05t2 + 3t + -30
40
min
10
-5
O neither of those parts
-10
That's right! For this part, we will need to look at the
behavior of c(t) on the graph to determine our integral.
-15
What is the exact total number of calories they burn from
t = 10 to t= 30? Show your work in the box below:
The total amount burned in from t= 10 to t= 30 is
cal/min
