Answer:
They got their points wrong, and did the wrong quadrant.
Step-by-step explanation:
Splitting up the interval of integration into
subintervals gives the partition
![\left[0,\dfrac1n\right],\left[\dfrac1n,\dfrac2n\right],\ldots,\left[\dfrac{n-1}n,1\right]](https://tex.z-dn.net/?f=%5Cleft%5B0%2C%5Cdfrac1n%5Cright%5D%2C%5Cleft%5B%5Cdfrac1n%2C%5Cdfrac2n%5Cright%5D%2C%5Cldots%2C%5Cleft%5B%5Cdfrac%7Bn-1%7Dn%2C1%5Cright%5D)
Each subinterval has length
. The right endpoints of each subinterval follow the sequence

with
. Then the left-endpoint Riemann sum that approximates the definite integral is

and taking the limit as
gives the area exactly. We have

The most precise is 4.00 because that is equal to 10.16 cm and that is the most closes to an exact measurment.
Area of the rectangle plus the area of the parallelogram...
53.3(11.1+6.8)
53.3(17.9)
954.07 in^2
Step-by-step explanation:
set up a proportion for a.
225/30=x/195. x=1462.5 milligrams daily
for b, if he gets 700 mg every 8 hours he only gets it 3 times a day. 700*3 is 2100, which means he is overdosing
