Are ghosts real?

How can evolutionists be so sure of things that happened millions of years ago?
Best answer: they would rather believe men OVER GOD... 
Find the units’ digit in the product 2468x8642?

How do I know if I am evolving into Gorilla like species?
Best answer: Gorillas cannot speak  their throats are anatomically wrong and their brains are missing certain necessary parts. Strength means nothing  if you can learn a language and talk, you're a human, you'll ALWAYS be a human, individuals do not evolve, only populations evolve, over generations.... 
Find the sum of 3 roots of eqn x^3+4x^2+x6=0?
Best answer: x^3 + 4x^2 + x  6= 0
(x  1) (x + 2) (x + 3) = 0
The sum of 3 roots:
3  2 + 1 = 4 
How to show the sum_(n=1) ^ infinity 1/2^n =1 algebraically?
Best answer: S = [n = 1→∞]∑(1/2ⁿ) = 1/2 + 1/4 + 1/8 + ...
2S = 1 + 1/2 + 1/4 + 1/8 + ...
2S  S = (1 + 1/2 + 1/4 + 1/8 + ...)  (1/2 + 1/4 + 1/8 + ...)
S = 1 + (1/2  1/2) + (1/4  1/4) + (1/8  1/8) + ...
S = 1
so [n = 1→∞]∑(1/2ⁿ) = 1 
True or False: Evolutionists cannot point to even one definitive example of an organism that has changed from one kind to another.?
If so  please name the organism 
Is ugly and weak is a genetic defect?
Best answer: No. Beauty is in the eye of the beholder, and "weak" is relative. A trait that is a "weakness" in one environment can be an asset in another environment

Help with simple differential equations y dy= x dx.?
I am told to find a solution of the differential equations y dy= x dx. What I did is integrate left and right hand side respectively end up with y^2=x^2+2c when its all cleaned up. The solution book says I should get is x^2y^2=C and I can see how I can get y^2x^2=C but not x^2y^2=C like book has. 
9,860 students in a population of 62,400 people. What percent of the total population is students?

Can a black hole be made from light?

Is college trigonometry in high school hard?
Best answer: If you don't know how to work a problem to solution, more like impossible.
Very very hard.
Learn the simple algorithms to work a problem, it is really quite simple.
Trig is hard, (read complicated)even for me, but grade 12 algebra in 7th grade was a breeze once learning how to work a problem. Same with trig. 
What kind of insect or bug is this?

Is 30.58 larger or smaller than 33.9?
Best answer: 30.58 is negative (less than 0) and 33.9 is positive (greater than 0).
Negative numbers are always smaller than positive numbers.
Update:
Regarding 30.58 and 33.9, think of negative numbers as being in a hole. Will you be lower if you are in a hole that is 30.58 meters deep, or in a hole that is 33.9 meters deep?
Or are you more in debt if you own someone $30.58 or if you owe someone $33.90?
Update 2:
For the same reasons, 18.93 is *larger* than 23.69. It is "less negative". Again if you would be closer to the surface in a hole that was 18.93 meters vs. 23.69 meters deep.
Answer:
33.9 is smaller than 30.58 because it is "more negative".
33.9 < 30.58
18.93 > 23.69 
Why do some people think that all scientists are emotionless?

Should we worry about a vacuum metastability event in our lifetime?
Best answer: No. The probability is infinitesimal. Besides, even if vacuum decay occurred somewhere in the universe it would travel at the speed of light. Even ‘nearby’ in the universe is 100’s of millions of light years away. 
Is 5G a real danger to people or just scaremongering?
david icke was saying recently in his latest video on youtube that 5G technology causes people health problems. to me, this makes worrying watching as i already live with terrible nerves and anxiety and seeing things like this can be frightening to me....especially when you already 'jump' at the drop of a hat. i ask; all these reports about 5G being dangerous to people and causing health problems is this scaremongering or is 5G something to be worried about? im hoping someone can put my mind at rest. 
Is there a formula to find the surface area and the volume of a cone?
