Answer:
2010.
Step-by-step explanation:
We have been given an exponential growth formula , which represents number of passengers traveling by airplane since 1990.
To find the year in which 900 million passengers will travel by airline, we will equate the given formula by 900 and solve for t as:
Take natural log of both sides:
Using property , we will get:
This means that in the 20th year since 1990, 900 million passengers would travel by airline.
Therefore, 900 million passengers would travel by airline in 2010.
Remember you can do anything to an equation as long as you do it to both sides
a=age
500 reduced by 2 times a is equal to 388
500-2a=388
minus 500 both sides
-2a=-112
divide both sides by -2
a=56
you are 56
Answer:
Step-by-step explanation:
<h3>Part A</h3>
- The base is a rectangle hence the parallel cut produces the same shape.
<h3>Part B</h3>
- The cut diagonal to base will produce rectangle as the cross section still contains two pairs of parallel lines
