Answer:
Step-by-step explanation:
using the formular for integration by parts;
∫udv = uv -∫vdu ..............equ 1
in the equation below;
∫
u=x , dv =
du= 1 v=
Substitute into equ 1
∫udv = - ∫
∫udv = - 
Answer:
- The first mistake was in not taking 18% off the iPad price. A second mistake was in using an incorrect value for the sales tax multiplier. Those two mistakes together are why the answer is incorrect.
- ($575 +0.82·2·499)·1.08875 = $1517.02
Step-by-step explanation:
iPads are 18% off on the day of purchase, so they should be charged at ...
100% -18% = 82%
of full price. The sum shown includes two iPads at $499 each, without any discount. The total price is too high by $179.64.
The tax rate is given as 8.875%, so the multiplier on price will be ...
100% +8.875% = 108.875% = 1.08875
The multiplier used by the student in the problem is 1.0875, so is too low.
_____
A correct computation could be written as ...
($575 + 2×499×0.82)×1.08875 ≈ $1517.02
3^2 + 4^2 = 5^2
65/5=13
3x13 =39
4 x 13= 42
