Answer: By moving from sea level to Mexico City air pressure is reduced by 25%.
Step-by-step explanation:
Hi, to answer this we have to apply a decrease rate formula
P0 (1-r)^x
Where:
p0= initial pressure
r = decrease rate. (0.4 = 0.4/100=0.004 decimal form)
x = feet (hundredths, since the air pressure decays every 100 feet we have to divide the input value by 100)
Replacing with the values given
P0 (1- 0.4/100)^(7340/100) =
P0 (0.996)^73.4 =
P0 ( 0.75)=
The air pressure at Mexico City compared to the sea level is 75% (0.75 x 100 =75%)
To obtain the percent decrease
100% -75% =25%
Answer:
Y= -3
Step-by-step explanation:
Step 1- 5y+2=-13 [move constant to the right]
Step 2- 5y=-13-2 [Calculate]
Step 3- 5y=-15 [Divide both sides]
And with doing these steps you'll end up with the answer Y= -3
Answer:
28,800
Step-by-step explanation:
thats the answer
The length of the parametric curve (call it <em>C </em>) is given by
We have
Now,
so that the arc length integral reduces to
which has an approximate value of 53.4596.
