seraphim [82]

Answer:

373.8mmHg

Step-by-step explanation:

a =height (in km) above sea level,

the pressure P(a) (in mmHg) is approximated given as

P(a) = 760e–0.13a .

To determine the atmospheric pressure at 5.458 km, then we will input into the equation

P(5.458km) = 760e–0.13a .

= 760e^(-0.13×5.458)

=760e^-(0.70954)

= 760×0.4919

=373.8mmHg

Therefore, the atmospheric pressure at 5.458 km is 373.8mmHg

denis-greek [22]

Answer:

D is the correct choice

Step-by-step explanation:

To get the y-intercept, we write the equation in the standard form

The standard form is ;

y = mx + b

So we have to rewrite the equation this very form

Thus, we have that;

0.05y = 0.4x + 1.25

we simply isolate the y value

To do this, we divide through by 0.05 and the y-intercept value will be ;

1.25/0.05 = 25
