Answer:
I don't see how the three existing points could ever become a square with the addition of a foiurth point.
Step-by-step explanation:
See the attached image.
A square would require that all angles be 90 degrees. The given points are the top three points on the graph. If we enter the two equations that intersect these points (blue and black lines), we can see that the angle on top is not 90 degrees. I can't see that this could ever be a square with a fourth point, z. I did find a value for z that make the four points a parallelogram.
Answer:
The interest rate for the given investment is 18%.
Step-by-step explanation:
We are given that,
The function representing the investment model is, .
It is required to find the interest rate for the investment.
Since, the function can be re-written as,
i.e.
So, on comparing with the formula for compound interest i.e. , where 'r' is the interest rate.
We have that,
The interest rate for the given investment is 0.18 i.e. 18%.
