The atmospheric pressure at a given altitude is given by $y=14.7 e^{-.0000385 x}$, where $y$ is the atmospheric pressure in pounds per square inch and $x$ is the altitude, in feet. Match each question with one of the solutions A, B, C, or D.
-What is the atmospheric pressure at an altitude of 10 yards?
A) Solve $\frac{1}{10}(14.7)=14.7 e^{-.0000385 x}$
B) Evaluate $14.7 e^{-.0000385(3 \cdot 10)}$
C) Solve $10=14.7 e^{-.0000385 x}$
D) Evaluate $14.7 e^{-.0000385(10)}$

Quizplus · Accepted Answer

To convert yards to feet, multiply by 3 (since there are 3 feet in a yard), then substitute $x = 3 \cdot 10$ into the given formula.
