Answer:
The distance between them is 230.65 miles
Step-by-step explanation:
Here we use the Cosine formula
Now the distance for one hour is
= 230.65 ÷ 1
= 230.65 miles
(11)q/2+8
(13)9x
(15)9 + (y × 3)
Set
so that the volume element is
The integral is then
and so evaluates to 0.
Split up [1, 3] into 4 subintervals:
[1, 3/2], [3/2, 2], [2, 5/2], [5/2, 3]
each with length (3 - 1)/2 = 1/2.
The right endpoints are {3/2, 2, 5/2, 3}, which we can index by the sequence
with .
Evaluating the function at the right endpoints gives the sampling points , {27/4, 5, 11/4, 0}.
Then the area is approximated by
