log (r+4)/r = log (r+1)

(r+4) = r^2+r

r^2 = 4

r = (+2,-2)

Factor out to 2pi, and you'll find out that cot(600pi) is just cot(0).
The cot(0)=undefined.

P stands for probability

P(RIGHT)=0.25
P(WRONG)=0.75
because the probability to give a right answer among 4 answers is 1/4.

A) P(X>=30) = P(X=30)+P(X=31)+...+P(X=50)
B) P(20<=X<=29) = P(X=20)+P(X=21)+...+P(X=29)
...that's the way for c and d

To calculate each probability, use this formula, i.e. P(X=30)=(50!/20!*30!)*(0.25)^30*(0.75)^20

1ft=12inch

18ft=216inch
12ft=144inch
room's area = 216*144=644.972.544 square inches
So, if 1 tile is 324 square inches, you will need 644.972.544/324=1990656 tiles

tile's width = tile's length = sqrt(324)=18
so the tile is 18x18

A=πr^2, so
πr^2 = 290
r^2 = 290/π
r = sqrt(290/π) = 9.60780240186586

4x + 2y = 6 | -4x
4x + 2y -4x = 6 -4x
4x-4x + 2y = 6 -4x
2y = 6 -4x | :2
2y/2 = (6 -4x)/2
y = (6 -4x)/2
y = 6/2 -4x/2
y = 3 -2x
y = -2x+3
[input]solve( 4x + 2y = 6, y )[/input]

-3x – y = 4 | +3x
-3x – y +3x = 4+3x
-y = 4+3x | *-1
y = -(4+3x)
y = -4-3x
y = -3x-4
[input]solve( -3x - y = 4, y )[/input]
