P = 14.7e-0.21x, where x is the number of miles above sea level. To the nearest foot, how high

Answer:

13064 feet

Step-by-step explanation:

We can rewrite the formula so that x is in feet. Equating the new formula to 8.743 PSI, we have ...

8.743 = 14.7e^(-0.21x/5280)

Dividing by 14.7 and taking natural logs, we have ...

ln(8.743/14.7) = -0.21x/5280

Multiplying by the inverse of the coefficient of x gives ...

x = 5280·ln(8.743/14.7)/-0.21 ≈ 13064.0806

Write an expression so that when you divide ¼ by a number the quotient will be greater than 1/4.

SVETLANKA909090 [29]

Hello There!

An example of this would be:
$\frac{6}{1/4}$
6 = $\frac{6}{1}$
$\frac{6}{1} * \frac{4}{1}$
= $\frac{24}{1}$
= 24

Hope This Helps You!
Good Luck :)
