Solve the problem.
-The atmospheric pressure on an object decreases as altitude increases. If a is the height (in km) above sea level, then the pressure P(a) (in mmHg) is approximated by P(a) = 760e-0.13a. Determine The atmospheric pressure at 7.176 km. Round to the nearest whole unit.
A) 4,789 mmHg
B) 261 mmHg
C) 299 mmHg
D) 379 mmHg

Question

Quizplus · Accepted Answer

To find the atmospheric pressure at 7.176 km, substitute a = 7.176 into the formula P(a) = 760e^(-0.13a). Calculating this gives approximately 299 mmHg.
