Answer:
It will take an interest rate of 8.1% to get 150% of the initial investment in just 5 years.
Step-by-step explanation:
Use the formula for continuous compounding
where r stands for the (annual) interest rate, t for time in years, P for the initial principal (investment) and X is the amount after t years.
(this formula can be beautifully derived from just basic considerations, btw)
We are given t=5, and percent increase on the initial P, so we can solve for r
It will take an interest rate of 8.1% to get 150% of the initial investment in just 5 years.
38
24- (-14) the minus cancel and become a plus
The answer would be D.
The highest power is a 3 which is odd and the leading coefficient is positive so it rises on the right and goes down on the left.
Answer:
<u><em>$330</em></u>
Step-by-step explanation:
Since it is simple interest. You would do 300*.05 which would be 15 than since it is simple interest you would do it again and get 15 again. Therefore you would have $330.
What we have here is a problem of proportions. We're assuming that the probabilities - the ratio of rainy days to total days - are equal; 3 is to 20 as <em>something</em> (let's call it <em>r </em>for "rainy days") is to 365. Mathematically, that gives us this equality:
To solve for <em>r</em>, we can simply multiply either side of the equation by 365:
365 and 20 have the factor 5 in common, so we can use that to reduce the fraction to:
So, the number of rainy days, if that pattern continued, would be around 54 3/4 days, or
55, rounded up to the nearest day.
