Wow that's a big threat. Don't want you to fail or loose your girlfriend so I'll help you out...
We know that x is 3 and y is -6 so replace the x and y with their corresponding numbers in the equation: 36x-8. So...
36(3) - 8
Multiply 36 and 3 together:
108 - 8
Square -6
108 - 8(36)
Multiply -8 by 36
108 - 288
Subtract them and you get...
-180
Hope this helped! And tell your gf not to break up with you since you got this question right lol
Answer:
x ≅ 20.10 torr
Step-by-step explanation:
Given that the equation which models blood pH in the question is;
pH(x)=6.1+log(800/x)
where;
pH = 7.7
x = partial pressure of carbon dioxide in arterial blood, measured in torr.
we are asked to find (x)
In order to do that, we use the given equation:
pH(x)=6.1+log(800/x)
since pH = 7.7
7.7 = 6.1 + log (800/x)
7.7 - 6.1 = log (800/x)
1.6 = log (800/x)
x = 20.09509145
x ≅ 20.10 torr
