describes a sum of the areas of 50 rectangles, each of width

, and the

th rectangle has height

.

ranges from a small positive number to 1, which means the integration interval must be
![[0,1]](https://tex.z-dn.net/?f=%5B0%2C1%5D)
. The sum is then the right-endpoint Riemann sum of

over the interval with

equally spaced subintervals, so

The sum itself evaluates to roughly 0.676, while the exact value of the integral is

.
Answer:
(-6,0) and (0,-6) are the points on the graph
Answer. A. 78.5 kg
Explanation. First, we must convert the lbs into grams, we can do this my multiplying 454 by 173 and get 78,500. Then convert it to kg, there are 1,000 g in a kg do divide 78,500 by 1,000 to get 78.5 kg. Let me know if it’s correct so others can use it. Brainliest would be appreciated.
Good luck :)
