Answer:
20
Step-by-step explanation:
locate 10 on the horizontal (x- axis), go vertically up to meet the line at (10, 20)
The corresponding output is the value on the vertical (y- axis )
That is the output is 20
it isn't lined up to x straight while it's crooked
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
divide 13 by 3
13/3 = 4.33 put a bar over the 2nd 3 because it just keeps repeating.
