Answer:

Air pressure = 4.6\frac{\text{lb}}{\text{in}^{2} }

Step-by-step explanation:

Relationship between air pressure and altitude can be modeled by,

P = 14.7e14.7e^{-0.00004h}

Where P = Air pressure

and h = altitude above the sea level

Air pressure on Mount Everest having altitude = 29028 feet abve the sea level will be,

P = 14.7e^{-0.00004\times 29028}

  = 14.7\times e^{-1.16112}

  = 4.603

  ≈ 4.6 \frac{\text{lb}}{\text{in}^{2} }

Therefore, air pressure on Mount Everest = 4.6 \frac{\text{lb}}{\text{in}^{2} }

Evaluate the expression 6 squared parentheses 2/5 + 5 parentheses -3​
antoniya [11.8K]

To start off you do what’s in parentheses

2/5 + 5 = 5 2/5 or 5.4 as a decimal

Then the exponent 6^2 which is 36

So far you have 36 (5.4) - 3

Now you multiply 36 by 5.4 which is 194.4

So now you have 194.4 - 3 which equals <u>191.4</u> which is you answer.

Hope this helped!
