Answer:
P(t) = 1000e^(0.01155)t
Step-by-step explanation:
Let the population of barangay be expressed according to the exponential formula;
P(t) = P0e^kt
P(t) is the population of the country after t years
P0 is the initial population
t is the time
If barangay has 1000 initially, this means that P0 = 1000
If the population doubles after 60years then;
at t = 60, P(t) = 2P0
Substitute into the formula
2P0 = P0e^k(60)
2 = e^60k
Apply ln to both sides
ln2 = lne^60k
ln2 = 60k
k = ln2/60
k = 0.01155
Substitute k = 0.01155 and P0 into the expression
P(t) = 1000e^(0.01155)t
Hence an exponential model for barangay's population is
P(t) = 1000e^(0.01155)t
Answer:
1. 8
2. -1/2
i dont know how to do the other problems, but i did know how to solve the 1st 2 questions. hope it helped :)
Step-by-step explanation:
3x + 2y = 12 5x - 2y = 4
-3x -3x -5x -5x
2y = 12 - 3x -2y = 4 - 5x
divide by 2 on both sides divide by -2 on both sides
y = 6 - 3/2x y = -2 + 5/2x
