At a nominal interest rate of i i convertible semiannually, an investment of 1,000 immediately and 1,500 at the end of the first year will accumulate to 2,600 at the end of the second year. Calculate i i.
Answer: unilateral contract
Explanation:
An unilateral contract is a contact that is formed when an individual offers to do a particular thing in return for either money or something else that was agreed on.
Once such individual does that thing, he or she has to be given what was agreed on in the contract. A typical example is the contact regarding an insurance policy.
Therefore, an offer that can only be accepted by an offere's performance will create a unilateral contact.
Although the focus vision is the one responsible for the targeting function, it is the central vision that allows the viewing of the line of sight to the target area. It is the central vision that allows a relative focus for mid distances and blurring of what's around. It is important on a motorway, for example, as what's ahead is the most important once there isn't people or very busy areas around.
Answer:




And if we convert this into % we got 
See explanation below.
Explanation:
We assume that we have compounding interest.
For this case we can use the future value formula given by:

Where:
FV represent the future value desired = 1000000
PV= represent the present value = 50000
i = the interest rate that we desire to find in fraction
n = number of times that the interest rate is compounding in 1 year, since the rate is annual then n=1
t = represent the number of years= 50 years
So then we have everything in order to replace and we got:

Now we can solve for the interest rate i like this:



And if we convert this into % we got 
2. It engages in business activities from which it may earn revenues and incur expenses.
