Rule. 5 )2+b2+(−5)2+b2

6. Solution, b=2 or b=-2, at this time c(0,2), or c(0,-2).

a|+|a-

6, i.e., 2a=6 or -2a=6, the solution is a=3 or a=-3, at which point c(-3,0), or c(3,0).

To sum up, the coordinates of point c are: (0,2), (0,-2), (3,0), (3,0).

So the answer is: (0,2),(0,-2),(3,0),(3,0).

Solution: There are two cases: with O as the center of the circle, draw an arc with 5 as the radius to cross BC at the point P, at this time OP=OD=5, in RT OPC, OC=4, OP=5, and PC=3 obtained by the Pythagorean theorem, then the coordinates of P are (3, 4);

Take d as the center of the circle, draw an arc with a radius of 5 to cross bc at p and p points, then dp =dp =od = 5, p as p n oa in n, in rt op n, let cp = x, then dn = 5-x, p n = 4, op = 5, from the pythagorean theorem: 42 + (5-x) 2 = 52, x = 2, then p the coordinates are (2, 4);

After p is p m oa in m, let bp = a, then dm = 5-a, p m = 4, dp = 5, in rt dp m, from the pythagorean theorem: (5-a) 2 + 42 = 52, the solution is: a = 2, bp = 2, cp = 10-2 = 8, that is, the coordinates of p are (8, 4);

There are three answers.

Don't forget to adopt the answer when you get it. It's been a long time.

14. Correct answer: d

Answer] D [Analysis] (1) Option A: There is no limit on the starting amount of exchange; (2) Option B: The remittance receipt can only be used as the basis for the remittance to be accepted by the remitting bank, and cannot be used as a proof that the remittance has been transferred to the beneficiary's account. (3) Option C:

The remitting bank shall take the initiative to return the remittance that cannot be delivered after "2 months" after issuing a withdrawal notice to the beneficiary.

15. Correct answer: c

Answer] C [Analysis] The interest income of treasury bonds is tax-exempt income from corporate income tax, and the interest income from corporate bonds should be taxed according to the regulations.

ac=ab+bc,be=bc+ce=bc-½abac·be=(ab+bc)·(ab/2+bc)-½ab|²+bc|²+ab·bc=1

i.e.: |bc|²+ab|·|bc|·cos( 芹乱3)-9 8=0bc|²+bc|-9/8=0

ad|=|bc|=1

f'(x)=-6x²+4tx=x(4t-6x)t=0 f'(x)<0 f(x) is monotonically decreasing with a unique zero point.

t≠ suspicion of giving way to 0

Stationing x = 0 x = 2t 3

There is only one zero point.

f(0)·f(2t/3)>0

i.e. 1· (-16T Huachun 27+8T 9+1)>08T 27>-1

t>-3/2
