The annual interest rate is 3.5%.
Solution:
Given Interest (I) = $26.25
Principal (P) = $500
Time (t) = 18 months
Rate of interest (r) = ?
Time must be in years to find the rate per annum.
1 year = 12 months
Divide the time by 12.
Time (t) =
years
Now, find the rate of interest using simple interest formula.
<u>Simple interest formula:</u>






⇒ r = 3.5%
Hence the annual interest rate is 3.5%.
Answer:the answer is B : -250
Step-by-step explanation:
Complex numbers have the form a + ib. Given a + ib, the complex conjugatet is a - ib.
Therefore, the complex conjugate of -1 + 3i is -1 - 3i.
