4a^4 -2b^2 +40
a=2
b=7
4(2)^4 -2(7)^2 +40
PEMDAS is what your gonna use to solve this you go from right to left
First is P which is parentheses which is none
second is E which stands for exponents
4(32)-2(49)+40
now MD multiply or divide
128-98+40
now add or subtract
30+40
last one
70 this is your answer i hope
Answer:
ppm value = 0.000027 parts per million
Step-by-step explanation:
Given:
number of parts(n) = 8
From table: percent conformance in six sigma = 0.9999966
Using the formula of ppm value in terms of percent conformance and number of parts:
![ppm\,value = ( 1 -( \frac{percent\,conformance}{100} )^n )](https://tex.z-dn.net/?f=%20ppm%5C%2Cvalue%20%3D%20%28%201%20-%28%20%5Cfrac%7Bpercent%5C%2Cconformance%7D%7B100%7D%20%29%5En%20%29)
Plugging in the values:
![ppm\,value = (1 - (\frac{0.9999966}{100} )^8 )](https://tex.z-dn.net/?f=%20ppm%5C%2Cvalue%20%3D%20%281%20-%20%28%5Cfrac%7B0.9999966%7D%7B100%7D%20%29%5E8%20%29)
![ppm\,value = ( 1- 0.999972)\\](https://tex.z-dn.net/?f=%20ppm%5C%2Cvalue%20%3D%20%28%201-%200.999972%29%5C%5C)
![ppm\,value = 0.000027\,parts\,per\,million](https://tex.z-dn.net/?f=%20ppm%5C%2Cvalue%20%3D%200.000027%5C%2Cparts%5C%2Cper%5C%2Cmillion)

Let's solve ~
We need to find volume of the given Cylinder, with information :
![\qquad \sf \dashrightarrow \:Volume_{(Cylinder)} = \pi r²h](https://tex.z-dn.net/?f=%5Cqquad%20%5Csf%20%20%5Cdashrightarrow%20%5C%3AVolume_%7B%28Cylinder%29%7D%20%3D%20%5Cpi%20r%C2%B2h)
![\qquad \sf \dashrightarrow \:Volume_{(Cylinder)} = \pi \sdot(12) {}^{2} \sdot17](https://tex.z-dn.net/?f=%5Cqquad%20%5Csf%20%20%5Cdashrightarrow%20%5C%3AVolume_%7B%28Cylinder%29%7D%20%3D%20%20%5Cpi%20%5Csdot%2812%29%20%7B%7D%5E%7B2%7D%20%20%5Csdot17)
![\qquad \sf \dashrightarrow \:Volume_{(Cylinder)} = \pi \sdot144{}^{} \sdot17](https://tex.z-dn.net/?f=%5Cqquad%20%5Csf%20%20%5Cdashrightarrow%20%5C%3AVolume_%7B%28Cylinder%29%7D%20%3D%20%20%5Cpi%20%5Csdot144%7B%7D%5E%7B%7D%20%20%5Csdot17)
![\qquad \sf \dashrightarrow \:Volume_{(Cylinder)} = 2448 \pi \: \: unit {}^{3}](https://tex.z-dn.net/?f=%5Cqquad%20%5Csf%20%20%5Cdashrightarrow%20%5C%3AVolume_%7B%28Cylinder%29%7D%20%3D%202448%20%5Cpi%20%20%5C%3A%20%20%5C%3A%20unit%20%7B%7D%5E%7B3%7D%20)
So, correct choice is B
The answer is a. You have the correct one highlighted I believe.
Hope this helps.
