If the principal is 2000 yuan and the compound interest rate is 5%, what is the interest rate for 9 months

If the principal is 2000 yuan and the compound interest rate is 5%, what is the interest rate for 9 months

After calculation, the annual interest rate of compound interest is 5%, and the annual interest rate of simple interest is 4.8889488%;
The converted monthly interest rate is 4.074124 ‰;
2000 * (4.074124 ‰ * 9) = 73.334232 yuan
A: if the principal is 2000 yuan and the annual interest rate of compound interest is 5%, the interest for 9 months is 73.33 yuan

From now on, the deposit at the beginning of every year is 1000 yuan, the annual interest rate is 12%, the compound interest is calculated once a half year, and the sum of principal and interest at the end of the fifth year is () yuan

1000*（1+0.06）^10=1790.85
Please accept

The annual interest rate is 12%, and the compound interest is calculated once a half year. The sum of principal and interest at the end of the fifth year is 1000 yuan. How much is the deposit now
formula
Is the formula iett = (1 + 10% / 2) - 1 = 12.36% 1000 / (1 + 12.36%) power 5

1、 You are doing the right thing
Effective interest rate = (1 + 12% / 2) ^ 2-1 = 12.36%
Compound interest present value = 1000 / (1 + 12.36%) ^ 5 = 558.39
2、 Another algorithm
Half a year interest, compound interest twice a year, compound interest times of five years = 2 * 5 = 10, cycle interest rate = 12% / 2
Present value of compound interest = 1000 / (1 + 12% / 2) ^ 10 = 558.39
The above answers, I hope to help you

How to memorize regional geography
It's not a rough outline. I've passed this part
The key is all the details of a large map, such as every mountain, every river, every province in the topographic map of China, as well as the provinces and topographical areas traversed by important longitudes and latitudes

Now that you have memorized the general outline, then add them to the map you remember according to the general shape of each mountain and river, Then, to the south, there are the Yellow River, the Yangtze River and the Pearl River; to the southwest, there is the Yarlung Zangbo River; to Xinjiang, there is the Tarim River, which is the most famous inland river in China. To the top, add others, such as the Liaohe River in the northeast and the Huaihe River in Central China. In the same way, add mountains to the map you remember. What are the directions of mountains and rivers
Don't you remember the location of the province? Divide the memory. That is to draw several longitude and latitude lines (horizontal and vertical lines) based on the places you have remembered, such as your hometown or Beijing, Shanghai, etc., and remember where the line passes, up and down or left and right. For example, a vertical line in Northeast China passes through three provinces, the right side of the line goes abroad, and the left side has only one province, Then it can be divided into two parts
Longitude and latitude can be based on the line above, how many longitudes and latitudes are broken. Roughly divide them evenly

How to determine the relative geological age of sedimentary rocks?

The relative age is determined by the sequence, original structure, unconformity, cross cutting structures and craters of the sedimentary rocks. (1) the new strata of the sequence are deposited on the older strata. Therefore, if they are not disturbed by folds or faults, the

The following statement is wrong: A. all kinds of rocks can form magmatic rocks; B. all kinds of rocks can form sedimentary rocks; C. all kinds of rocks can form metamorphic rocks
Please select

It must be a, because magmatic rock can only be formed after magma cooling, while sedimentary rock is formed by consolidation diagenesis after magmatic rock and metamorphic rock are weathered by external force. Metamorphic rock is formed by metamorphism after magmatic rock and sedimentary rock re accept the conditions of high temperature and high pressure inside the earth under certain conditions. So a is wrong

How to judge sedimentary rock
For example, if I give you a section of stratigraphic structure of a certain place, how can I judge? If there is obvious bedding structure in sedimentary rock, how can I judge this bedding structure? Is there a better way

According to the requirements of the curriculum standard for senior one students, it is difficult to learn the stratigraphic structure profile, but it is not very difficult to master it. For this problem, you first need to know several types of rocks and their formation mechanism. The formation of sedimentary rocks is caused by external forces (water deposition, sand blown deposition, etc.), It has a very regular bedding structure. If it is difficult to understand, imagine it as a book, page by page, even layer by layer. This is the original appearance. After the formation, with other functions, it will form a complex stratum, but no matter how it changes, its bedding will always be layer by layer. I hope it will be useful to you!
