I haven't had much luck with this question, but does ANYONE know if you need to be licensed or certified to be a paranormal investigator and have a organization? If anyone has ANY clue, please let me know.

1. bx + c = d + 3x
2. 2ax + b2 = 4a2 + bx
3. x + 7/ 3a = 5/6 + a
4. 1/b + 1/x = 1/c - 1/x

solve the following equations

sin x = sin x tan x ,0< or equal x < or equal 360 degrees

ans :0 , 45 ,180,225,360 degrees

i would like to know how to get the ans 0, 180 and 360?

because i do in this method and only managed to get 2 answers from the 5 answers

sin x/ sin x tan x =1
1/ tan x =1
tan x =1 (1st/3rd quadrant)
basic angle = tan inverse 1
= 45 degrees

x = 45 , 180+45
= 45 , 225 degrees

Lets say a time traveler from the year 2006 arrived in 2003. The time traveler stayed in the past for 4 years. After 4 years it is 2007 would the time traveler still be from the future even though the time traveler only made one trip to the past and zero trips to the future?

Seems the beaches whould shift or change and a flood of water would rush in.
I'm not referring to Tsunami/earthquake but to changes like cave ins or just daily shifting of sand. Has this ever been documented in all history?

Does anyone else think its funny/ridiculous during the air hostess demonstrations that they say in case the plane lands on water the seat can be used as a float. Who has ever heard of a commercial jet land successfully on water. Please someone explain if its possible to do this and why the gov allows airlines to give this false sense of security.

What was the percentage of increase in motor vehicle production in countries outside the United States from 1950-1997?
1950=2571
1997=41344
so, I subtract 2571 from 41344 and get the increase number of 38773
next 28773/2571 and I get 11.19...have I done it right up to now and if so, what next...please help!!
Thank you!

When an evaporated sweat rate of 0.26 litres (kg) per hour corresponds to a heat loss of 100 Wm-2. to maintain heat balance the body would therefore have to produce 0.454 litres of sweat per hour that is

R = 1 - 0.932
2
Sreq = 97.88
0.56

= 174.79 wm-2
= 0.454 litres per hour.

How did they work out it was 0.454 litres per hour?
