Answer:
population will be 79806.
Step-by-step explanation:
Population of a town 4 years ago was 50,000
Population of town had grown exponentially and present population is 63,124.
So the formula of the population growth will be
Where 
= Final population n = number of years.
= Initial population
r = rate of increase in population per year.
so 63124 = 50,000 
= 1.0813
Now we have to find the population after 4 years from now.
= 
= 
= 63124 × 1.264
= 79806
Therefore, after 4 years from now population will be 79806.
Answer:
The multiplicative rate of change is 0.5.
Step-by-step explanation:
The given function is
.... (1)
It is given that the curve is passing through (0,10), (1,5) and (2,2.5).
The exponential function is defined as
.... (2)
Where, a is initial value and b is growth factor of multiplicative rate of change.
On comparing (1) and (2), we get
Therefore the multiplicative rate of change is 0.5.
Answer:
m = v + 2
Step-by-step explanation:
Since Mags (m) is 2 years older than Vector (v)
You can use the equation V + 2 which is Vector's age + 2 years. Which would be equal to Mags' age.
Answer:
D. 14.73
Step-by-step explanation:
According to Pythagoras,
19^2 = 12^2 + x^2
x^2 = 19^2 - 12^2
x^2 = 361 - 144
x^2 = 217
x = 
x = 14.73
