A town has a population of 6000 and grows at 3.5% every year. To the nearest year, how long will it be until the population will
kotykmax [81]

Answer:

5 years.

Step-by-step explanation:

Every year the population increases by a factor 103.5% or  1.035.

The equation relating population and time in years is:

P = 6000(1.035)^t  (This is an example of  exponential growth)

So we have:

7100 = 6000(1.035)^t

(1.035)^t = 7100/6000

(1.035)^t = 1.1833

t ln 1.035 = ln 1.1833

t = ln 1.1833/ln 1.035

= 4.89.

19, find the direction angle of vector v to the nearest tenth of a degree
labwork [276]
The vector v is given by:
 v = (7, 2) - (-5, 0)
 v = ((7 - (- 5)), (2-0))
 v = ((7 + 5), 2)
 v = (12, 2)
 Then, the angle is given by:
 tan (theta) = 2/12
 theta = atan (2/12)
 theta = 9.46 degrees
 Answer:
 
The direction angle of vector to the nearest tenth of a degree is:
 
theta = 9.5 degrees
