A meteorologist is monitoring the atmospheric pressure at various cities whose height above sea level varies. The meteorologist

determines that the atmospheric pressure decreases by 12% for each additional kilometer the city is above sea level. It has been determined that the atmospheric pressure at sea level is 103 kPa (kilopascals).
Determine the atmospheric pressure in the following cities.

A city located 4.6 km above sea level

If the pressure decreases 12% per kilometer of elevation,
then this would be the equation:

      Pressure = (pressure at sea level) · (0.88)^power of (elevation in km) .

If the sea level pressure is 103 kPa and
the city is 4.6 km above sea level, then

      Pressure = (103 kPa) · (0.88)⁴.⁶          (the exponent is " 4.6 ")

                    =  (103 kPa) · (0.5554)

                    =   57 kPa        (rounded) 
__________________________________________

4.6 km is a very high elevation for people to live at.  One reason is just
what we found up above ... the low air pressure makes it tough to get
enough oxygen into your lungs to be able to DO anything.  You would
just have to lay around all day trying to breathe !

I did some searching online looking for major cities at 4.6 km elevation,
and I didn't find any.

4.6 km is almost 3 times as high above sea level as Denver, Colorado is.

A line passes through the points (-1, -6) and (-4, 3). What is the equation of this line in slope-intercept form?
g100num [7]

Since we have two ordered pairs, we can find the slope by plugging them into (y2-y1)/(x2-x1) which translates to (3-(-6))/(-4-(-1))=9/-3=-3

Since the slope is -3, we have the equation y=-3x+b, but we don't know b. So we plug in values for x and y and solve for b.

-6=-3(-1)+b

-6=3+b

-9=b

So the y-intercept is -9 and the full equation is y=-3x-9 which means A is the only correct answer.

Hope this helped!

A skydiving company insists
34kurt

Answer:

A skydiving company insists that its customers weigh at least 130 pounds, but no more than 280 pounds, including parachute and other gear. If the total weight of all gear is 25 pounds, write and solve a compound inequality that represents the weight range without gear that is acceptable.

105 ≤ x ≤ 255

think this is what you meant . . .

what’s the difference between the area of the larger circle and the area of the smaller circle? in pi
Arisa [49]

Answer:

105 pi m^2

Step-by-step explanation:

radius squared - radius squared =

(16+3)^2 - 16^2 =

19^2 - 16^2 =

361-256= 105

What is the slope of this equation please help me
galina1969 [7]
The slope is always change in y value over change in x value so if you pick any 2 points on the line you’ll see that the slope is 30/40 and that simplified is 3/4 so the slop is 3/4

What is the kinetic Energy of a camion of 5,000 kg and turn at 100km/h ?
Alex787 [66]

Step-by-step explanation:

Given

mass (m) = 5000 kg

velocity (v) = 100 km/h = 100* 1000/ 3600 = 27.78m/s

Now

Kinetic energy

= 1/2 mv²

= 1/2 * 5000 * 27.78²

= 1929321 joule
