1000 students.
1. Suppose the first student goes along and opens evvery locker.
2. the second studentv goes along and shuts every other locker beginning with number 2.
3. the third student then goes along and changes the state of every third locker beginning with the number 3. (if the locker is open, the student shuts it and if it's closed the student will open it)
4. the fourth student changes the state of every fourth locker beginning with number 4.

if this continues until all 1000 students have followed the pattern with these lockers, which lockers will be open and which will be shut at the end? why?

if man was able to land on the moon nearly 40 years ago in a craft that landed perfectly without any hitch,　why wasnt the same or better technology used for the rovers' (Spirit and Opportunity) landing? Instead of the airbag cushioned landing?
space engineers, any explanation? Thanks

How do you do this. The directions say solve and check the equation. Begin work y rewriting the equation without fractions.

the problem is

7y/15 -5 = y/5 -1

please show you work so that i understand this problem.

thanks.

And i dont mean "its lightning duh" i mean in a scientific manner please. I'm just curious as to what is causing that noise. Or if its an exothermic reaction and the noise thunder is just a byproduct. I'd like a scientific answer with a reputable source as well. Thanks.

hi, i have a math test tomrrow and i cant figure out these questions on my review sheet.

1. determine the equations of the lines with slope-5 that intersect f(x)= -7x^2 -5x +4 once, twice or never.

2. also, how do you "solve the system" (i think they mean find the points of interesection). between y=4(x-2)(x+5) and y=-4x+44 ?

3. and this quick one. solve for x. 0= -5(x-3)^2

4. how do you know if two lines have more than one intersection?

i lkeep doing it and keep getting the wrong answers..




ANSWERS:
------------------
1. y=-5x +k, k=4, one solution, k> 4 no solutions, k<4 two solutions.

2. (-7, 72) and (3,32)

3. 3 plus/minus squareroot of 2. approx 1.6 or 4.4
