(1) If the parabola y = x ^ 2 - 2x + 4 and the straight line y = KX have two different intersections, the value range of K is obtained
(2) Find the range of function y = 3 + root 6x-x ^ 2-5
Thank you for your advice

1. Substituting y = KX into y = x ^ 2 - 2x + 4, we have two solutions, K ^ 2 + 4k-4 > 0, and find the solution by ourselves

A and B practice running on the 400 meter circular track. A runs 250 meters per minute, B runs 170 meters per minute. If a runs for 24 seconds, B starts from the same place and direction. How long does it take for them to meet for the first time?

Suppose they meet in X minutes
250*X+250*24/60-170X=400
X = 3.75 (min)

The distance from the moving point P to the fixed point F (1,0) on the plane is equal to the distance from the point P to the Y axis. The trajectory equation of the moving point P is obtained

Let P (x, y) then
(x-1)^2+y^2=x^2
Well organized
y^2=2x-1

Factorization 4-12 (a-b) + 9 (B-A) ^ 2
Be more specific

Original formula = 9 (a-b) & sup2; - 12 (a-b) + 4
=[3(a-b)]²-2*3*2(a-b)+2²
=[3(a-b)-2]²
=(3a-3b-2)²

There are five Fridays and four Saturdays in October of a certain year. What day is October 1st of that year?

October has 31 days;
[[first Friday, first Saturday...] The fifth Friday (29 days in total) and the fifth Saturday
The fifth Friday is October 31st, and the fifth week is November 1st, so October 1st is Wednesday

A math problem, how to list the formula?
A and B start from a to B at the same time. A walks 7 kilometers every day. B walks 1 kilometer the first day and 2 kilometers the next day... (1 kilometer more than the previous day every day). What day do they meet?
I know it's the 13th day, but I don't know how to write the formula. Who can list a formula?

A 7x
B 1 + 2 + 3 +. + x = (x + 1) x / 2
7x=（x＋1）x/2
x=13

What day is new year's day in 2007?
