An exponential equation is represented through the equation;
y=abˣ
Here, a represents the starting value/point and
b represents the number by which the equation exponentially increases/decreases by.
In the given situation, a would be represented by the number $400,000.
Hope I helped :)
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%
$16.50 x H = total money earned
