Answer:
Step-by-step explanation:
We want to find the Riemann sum for with n = 6, using left endpoints.
The Left Riemann Sum uses the left endpoints of a sub-interval:
where .
Step 1: Find
We have that
Therefore,
Step 2: Divide the interval into n = 6 sub-intervals of length
Step 3: Evaluate the function at the left endpoints
Step 4: Apply the Left Riemann Sum formula
(-8,8)
x=18 y=9
The temperature yesterday was -6 because 7-13 is -6.
x=0.875
3x-6=2-5x
Add 6 on both sides (6+2)
2x=8-5x
Add 5x on both sides
7x=8
Divide 7 from both sides
