Answer:
$474
Step-by-step explanation:
Ellen's pay is:
Fixed Weekly Salary (that is $330) + 12% commission on Sales
We already know her fixed salary part. Let's figure out her last week's commission and add it to her fixed salary to find her total pay.
12% is 12/100 = 0.12
To find 12% of 1200, we multiply 1200 with 0.12. We get:
So her commissions for last week is $144.
Total Pay Last Week = 330 + 144 = $474
-4
2 1/4 - 7 1/2 = -5.25
-5.25 - (-1 1/4) = -4
f(x - 2) = 8x - 16
f(x) = 8x
f(x - 2) = 8(x - 2)
Split up the interval [0, 8] into 4 equally spaced subintervals:
[0, 2], [2, 4], [4, 6], [6, 8]
Take the right endpoints, which form the arithmetic sequence
where 1 ≤ <em>i</em> ≤ 4.
Find the values of the function at these endpoints:
The area is given approximately by the Riemann sum,
where ; so the area is approximately
where we use the formulas,
