Answer:
Choice A is correct
Step-by-step explanation:
When calculating the effective rate of interest of a loan, the nominal rate of interest will be equal to the effective rate and the interest is compounded annually in the event that n is equal to 1.
If the duration of the loan, n, is 1 then the nominal rate and the effective rate will always be equal. Moreover, the interest rate charged on the loan is usually stated as an Annual Percentage Rate (APR) of charge compounded annually
To determine this easily, figure out what two numbers will make a product ending with "2", (4 & 3, 8 & 9)
Since the square root of 625 is 25, it is obviously less than 25.
I used 18 and 19, and they are the correct answer.
I believe the 2 is the largest
Answer:
12y +16yi
Step-by-step explanation:
The thing about complex numbers is that you can treat them as binomials and use all of the things you know about multiplying and factoring polynomials.
Here, we assume you have ...
(5 +2yi)(4 -3i) -(5 -2yi)(4 -3i)
The factor (4 -3i) can be factored out, so you have ...
= ((5 +2yi) -(5 -2yi))(4 -3i)
= (4yi)(4 -3i)
= 16yi -12yi²
At this point, the definition of i comes into play, and you replace i² with -1.
= 12y +16yi
