HARDEST QUESTION OF ALL TIME CAN YOU SOLVE IT? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Answer:

PN2 = 191.3kPa

Step-by-step explanation:

Ptotal = PO2 + PCO2 + PN2 + Pothers = 245.0kPA

Work backwards to find PN2

245.0kPA - PO2 - PCO2 - Pothers = PN2

245.0kPA - 51.3kPa - 0.10kPa - 2.3kPa = PN2

245.0 - 51.3 = 193.7

193.7 - .10 = 193.6

193.6 - 2.3 = 191.3

What is the answer to 21=(x+3)2
IceJOKER [234]
First, distribute 2 to the (x+3) to get:
21 = 2x+6
subtract 6 from both sides to get:
15 = 2x
Finally, we divide both sides by 2 to simplify x to:
x = 7.5 (OR) x = 7  \frac{1}{2}
(Just so you know, if you pick a brainliest answer, both you and the person who got the brainliest answer get some points.

Answer:

P(x) = -0.25x^2 + 42x - 90

Step-by-step explanation:

Given

C(x) = -17x + 90

R(x) =- 0.25x^2 + 25x

Required

Determine the profit function.

Profit function is calculated as thus:

P(x) = R(x) - C(x)

So, we have:

P(x) = -0.25x^2 + 25x -(-17x + 90)

P(x) = -0.25x^2 + 25x + 17x - 90

P(x) = -0.25x^2 + 42x - 90
