If you haven't matched yet, I suggest you choose AMD's platform. AMD's most dominant price comparison, in the same price CPU, is better than Inter Milan. I recommend a list, at least a little better than yours. Computers depend on integration.

CPU:AMD7750 black box 405 yuan

Motherboard: mini K9A2 NEO2-F 540 yuan

Graphics card: sapphire HD3850 5 12M platinum 2nd generation 490 yuan.

Memory: Kingston DDR2/800 (two) 140 yuan.

Chassis: local 120 yuan, just ordinary materials.

Optical drive: No (DVD/ 18X is 1 15 yuan).

Power supply: Great Wall BTX-400SEL-P4 (dual power mute maximum output 400W) 255 yuan.

Monitor: AOC F19 (12000:1) 680 yuan.

Total: 2630 yuan. On this basis, let the merchants give you a discount of 2520 yuan. This configuration can cope with all the games and software now, and the price is good. The CD-ROM drive is only 2650 yuan.

By the way, there is also a hard drive. Seagate 320G hard disk 330 yuan is about 3000 yuan ~

Here is a math problem, please help1/5 < = a < =5

The landlord asked: a+ 1/a or (a+ 1)/a?

Let f (a) = a+1/a.

Derive f (a)' =1-1/a * a.

Let f(a)'=0 to get a= 1 or-1.

When 1/5

Then f (1)

Namely 2

When 1

Then f (1)

Namely 2

Scope 2, 26/5

If you find (a+ 1)/a, it will be simple.

Simplified as: 1+ 1/a

Range 6/5, 6

(2m^2+6)/(m+ 1)

=[2(m^2- 1)+8]/(m+ 1)

=[2(m+ 1)(m- 1)+8]/(m+ 1)

=2(m- 1)+8/(m+ 1)

=2(m+ 1)+8/(m+ 1)-4

m & gt- 1,2(m+ 1)>0,8/(m+ 1)>0

so 2(m+ 1)+8/(m+ 1)>; =2 radical number [2 (m+1) * 8/(m+1)] = 2 radical number 16=8

2(m+ 1)=8/(m+ 1) takes the equal sign.

(m+ 1)^2=4

m+ 1 & gt; 0, so m+ 1=2.

m = 1 & gt; - 1

So you can get the equal sign.

So (2m 2+6)/(m+1) = 2 (m+1)+8/(m+1)-4 > = 8-4 = 4.

So the scope of resignation is [4, +∞)

How to calculate the expected date of delivery? Thank you for your help. Hello, the expected date of delivery is calculated from the date of the first day of the last menstruation in the solar calendar. The calculation method of the expected date of delivery is: the expected date of delivery is the number of last menstrual months plus 9 (or minus 3), and the number of days plus 7.

The last menstrual period was 201August 2 1 day. The expected date of delivery is around May 28th, 20 14, and there are about 70 days before the baby is born.

I wish mother and son peace and happiness!

Please help us teach you how to fill in the account summary table and summarize all accounting vouchers of this month according to the account. For example, all debits in cash are added, credits are added, debits are filled in the account summary table, credits are filled in the account summary table, and so on. The result should be that the total debit is equal to the total credit. According to this, the general ledger is registered, and the balance of the general ledger is checked with the balance of the subsidiary ledger, which plays the role of parallel recording and reconciliation.

The account summary table is filled in according to the loan amount of each account in the accounting voucher! Fill in account code, account name, debit number, credit number and period-end total: debit number = credit number = credit number.
