A city's population is 12,000 and grows at 2.6% rate. What will the population be after 25 years? A city's population is 230,000
Levart [38]

Answer:

The 12000 City would become 22,986 people, while the 230,000 city would become a population of 124,223.

Step-by-step explanation:

1st Part:

=12000⋅(0.026000000000000002⋅25)

=12000(2.718281828459045)(0.65)

=22986

2nd Part:

=230000⋅(−0.044000000000000004⋅14)

=230000(2.718281828459045)(−0.616)

=124223

The graph shows the altitude of a helicopter over time. A graph measuring altitude and time. A line runs through coordinates (0,
TiliK225 [7]

We can calculate for the slope of the line using the formula:

m = (y2 – y1) / (x2 – x1)

 

From the given values:

m = (4,000 – 10,000) ft / (15 – 0) min

m = -400 ft/min

This means that the altitude is decreasing by 400 ft per minute.

 

 

> The slope is –400 . This means that the helicopter descends 400 ft each minute.
