Without any more information, it sounds like interest is compounded continuously, in which case the value of the investment <em>A</em> is given by
where <em>P</em> is the principal investment, <em>r</em> is the interest rate, and <em>t</em> is the number of years.
At the end of the second year (<em>t</em> = 2), the value is <em>A</em> = 60,500, and after the fourth year (<em>t</em> = 4), the value is <em>A</em> = 73,205. So solve the system
for <em>r</em>. You can eliminate <em>P</em> by dividing
Take the logarithm (log here means natural log) of both sides to get
2<em>r</em> = log(121/100)
<em>r</em> = 1/2 log(121/100)
<em>r</em> ≈ 0.0953
So the interest rate is about 9.53%.
Answer:
$30,000.
Step-by-step explanation:
Wave Corporation began the current year with a retained earnings balance of $25,000.
Depreciation expense was of $5000
During the current year, the company earned net income of $15,000
Also gave cash dividends of $5,000.
So, year end retained earnings will be :
Year end retained balance = total net income minus net losses and dividends.
dollars
The answer is $30,000.
Answer:
Step-by-step explanation:
The only graph shown in the question doesn't have amplitude 1/2. look for a graph of a periodic wave function that has maximum y-value 1/2 (0.5) and minimum y-value 1/2 (0.5), or if it is not oscillating around the x-axis, verifies that the distance between minimum y-value and maximum y-value is "1" (one). This is because the amplitude is half of the peak-to-peak distance.
Look at the attached image as example.
