Tan(330) = tan(360-30) = tan(-30) = -tan30 = -sqrt(3)/3
Answer:
R = 1.2%
Step-by-step explanation:
<u>Given the following data;</u>
Principal = 425
Time = 2
Simple interest = 10.20
To find the annual interest rate;
Mathematically, simple interest is calculated using this formula;
![S.I = \frac {PRT}{100}](https://tex.z-dn.net/?f=%20S.I%20%3D%20%5Cfrac%20%7BPRT%7D%7B100%7D%20)
Where;
- S.I is simple interest.
- P is the principal.
- R is the interest rate.
- T is the time.
Substituting into the equation, we have;
![10.20 = \frac {425*R*2}{100}](https://tex.z-dn.net/?f=%2010.20%20%3D%20%5Cfrac%20%7B425%2AR%2A2%7D%7B100%7D%20)
![10.20 = \frac {850R}{100}](https://tex.z-dn.net/?f=%2010.20%20%3D%20%5Cfrac%20%7B850R%7D%7B100%7D%20)
Cross-multiplying, we have;
![1020 = 850R](https://tex.z-dn.net/?f=%201020%20%3D%20850R%20)
![R = \frac {1020}{850}](https://tex.z-dn.net/?f=%20R%20%3D%20%5Cfrac%20%7B1020%7D%7B850%7D%20)
<em>R = 1.2%</em>
<em>Therefore, the annual interest rate is 1.2 percent. </em>
What is this supposed to mean?
I need more information so I can give you an answer
Answer: Hexagon AGHBGHCGHDGHEGHFGH coincides with hexagon ABCDEF when GH passes through themidpoints of opposite sides; that is, it is a perpendicular bisector of the two sides. HexagonAGHBGHCGHDGHEGHFGH also coincides with hexagon ABCDEF when the line of reflection joins a pair ofvertices opposite one another on the hexagon. There are three perpendicular bisectors and three pairs ofopposite vertices. In all, there are six lines of reflection that will map the hexagon back onto itself.
