Answer:
20.5 years
Step-by-step explanation:
The population is given by the exponential function ...
p = 16000·(1 +0.022)^t
When p = 25000, we can find the value of t by taking logarithms.
log(25000/16000) = t·log(1.022) . . . . . divide by 16000, take the log
t = log(25/16)/log(1.022) ≈ 20.5 . . . . . . divide by the coefficient of t
It will take about 20.5 years for the population to reach 25000.
Answer:
(7, - 1 )
Step-by-step explanation:
Given the 2 equations
2x + 4y = 10 → (1)
- 2x + y = - 15 → (2)
Adding the 2 equations term by term eliminates the term in x, that is
5y = - 5 ( divide both sides by 5 )
y = - 1
Substitute y = - 1 into either of the 2 equations and solve for x
Substituting into (1)
2x + 4(- 1) = 10
2x - 4 = 10 ( add 4 to both sides )
2x = 14 ( divide both sides by 2 )
x = 7
Solution is (7, - 1 )
