$40+$35=$75
75/100*8.75=6.5625
6.5625+75=81.5625
approximately equal to $81.56
Split up the interval [0, 3] into 3 equally spaced subintervals of length
. So we have the partition
[0, 1] U [1, 2] U [2, 3]
The left endpoint of the
-th subinterval is

where
.
Then the area is given by the definite integral and approximated by the left-hand Riemann sum

Answer:w=6+t/3/2 squared
Step-by-step explanation:
2 squared w= 6+t/3
w=6+t/3/2 squared
