A if you went 130 miles at 65 miles an hour it would take two hours
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: 45000
Step-by-step explanation:
From the question, we are informed that Patty buys a new car and gets it appraised every few years and that after owning the car for 3 years, its value is $15,000 and further told that after owning the car for 5 years, its value is $9,000.
Let the number of years be x
Let the value of the car be y.
From the first part of the question, we are told that after owning the car for 3 years, its value is $15,000.
Since an inverse variation will be:
x = k/y
3 = k/15000
k = 15000 × 3
k = 45000
Let's confirm the value of k for the second part of the question. After owning the car for 5 years, its value is $9,000. Here, x=5 and y = 9000
x = k/y
x = 45000/9000
x = 5
It's correct.
Therefore, the constant of proportionality is 45000
