Answer:
It will take about 7.3 years for his money to triple.
Step-by-step explanation:
Identify the variables in the formula.
A = 150,000
P = 50,000
r = 0.15
t = ?
A = Pe^rt
Substitute the values into the formula.
150,000 = 50,000e^0.15*t
Solve for t. Divide each side by 50,000.
3 = e^0.15*t
Take the natural log of each side.
ln 3 = ln e^0.15*t
Use the power property and then simplify.
ln 3 = 0.15*t ln e
ln 3 = 0.15-t
Divide each side by 0.15.
(ln 3)
/(0.15) = t
Approximate the answer.
t ≈ 7.3
The formula of the given problem in function form is
L(t) = 150 - 25t where, t represents the hour
Step-by-step explanation:
Given,
Ray reads the at a constant rate of 25 pages per hour.
To find, the function L: the pages left to read
Let, t be the hours
So, in t hours he read 25T pages
After T hours he was left with (150 - 25t) pages to read.
Formula
Hence, the required function will be
L(t) = 150 - 25t where, t represents the hour
So, the equation would be -
1.50x + 10 = 40
and you have to find the value of x
1.50(?) +10 = 40
The value of x would be 20
1.50 x 20 = 30 +10 = 40
Your answer would be that
