Ask the master to explain, and ask the gods to explain

36 issues changed for 15 issues, and 12 issues remain? I don't know how to do it. It means that the repayment principal of the 21 installments will be divided into 12 months, and then you will be given some interest discounts (in fact, there is no discount at all, and you may lose money) To put it bluntly, the borrowing platform is in a hurry to recover the cost.

For example, 1 month is still 1000Interest 100The remaining 21 months are to repay the principal of 21,000.

The interest is 2,100 yuan, and the total amount must be repaid 10,000 yuan. Now it has become 12 months, and the principal is 1750 per month, and the interest is 120A total of 10,000 will be repaid.

It's literally 660 yuan cheaper, but it's actually a loss.

Let t=x+2 then substituting t 0 gives f(x)=a- 2a t because decreasing so -2a is greater than 0 so a is less than 0

How many times in the 24 hours of the day do the hour, minute and second hands of the clock coincide exactly?

11 2 = 22 times.

1 o'clock, 13:30 (another 5 11 minutes.)

2 o'clock, 2 p.m. 60 p.m. (10 11 p.m.)

3 o'clock, 15:90 (4 11 minutes.)

4 o'clock, 16 o'clock 120 (again 9 11 minutes.)

5 o'clock, 17 o'clock 150 (again 3 11 minutes.)

6 o'clock, 18 o'clock 180 (again 8 11 minutes.)

7 o'clock, 7 p.m. 210 (again 2 11 minutes.)

8 o'clock, 20 o'clock 240 (again 7 11 minutes.)

9 o'clock, 21 o'clock 270 (again 1 11 minutes.

10 o'clock, 22 o'clock 300 (again 6 11 minutes.)

12 o'clock and 24 o'clock.

Haha, that's an interesting question. Express your personal opinion: Do you still remember Wang Jianlin's famous statement some time ago: "a small goal of 100 million"? I think there is a truth: that is, the standards are different.

For Wang Jianlin, 100 million is just a small goal, but it is out of reach for others. In the same way, for the wicked, as long as he can not harm others (i.e., put down the butcher's knife), he is a complete merit; But for good people, whether or not they harm others is not considered at all, and good people think about how many sentient beings they can help.

This is like eating a meal, people's practice is to go through some processing to achieve the color, flavor and flavor, while animals are swallowing dates directly into the stomach.

It's really stupid, a bad guy who does so many bad things and is fine, there must be a background, of course it's easy to have a background, I've seen Journey to the West, it's all very clear.

If we analyze it with the same relationship, it can only be said that it is 81 difficult to kill people with a butcher knife, so you can become a Buddha immediately by putting down the butcher knife.

fun() is equivalent to the string concatenation function, strcat

Picked some auspiciousness to the East, asked the West for a trace of good luck, borrowed a wishful thinking to the south, pulled a handful of peace in the north, and gave all of these to you, New Year's Day is here, may all the happiness from all sides rush to you, Happy New Year's Day!

Because n tends to infinity, so.

n+1) = n, both tend to infinity.

Then the denominator is 2 n, n 2 n=1 2

It's only one step, but it's the mind.

Make perpendicular lines from O to Cd and intersect Cd at E, because: oc=od=m, oe=m.

oab=∠ocd=α

So, sin = oe oc

or sin =

Find, cos

and cd=2*CE

2*oc*cosα

2*= (m).

Thus, we get: OAB= ocd degrees, and the length of the cd is about meters.
