I have watched many live autopsy clips on the web, and all of them involved Skull-opening...just wonder, let's say, if a person was found dead with a apparent gunshot wound to the heart, is it still necessary to open his skull and take the brain out for further inspection?

where the county road grader probably just road maintenance had revealed acres of them. I brought some samples home and took a couple of them to work boasting I had found fossils a million years old. In reality I think they are millions of years old. My question is how many millions of years ago did the great salten sea I have heard about cover half of the state of Kansas? Should I report my findings to someone? We are talking literly acres and acres of these kinds of fossils

True or False? and why?

A sheet of canvas is fixed to a wooden frame. The frame is placed in a subway station so that it is parallel to the passing trains. As a train comes in and decelerates, the canvas bulges away from the train. As the train leaves and accelerates, the canvas bulges towards the train.

how do you solve for x?
1) x^2 -4x+20=0
2) x^2 -25 =0
3)2x^2-x-3=0
how do you factor these?
y=x^2 + x -6

y=x^2 -7x

y= x^2 + 20x + 100

y= 3x^2 -x-24

square root of -9 + square root of -16

5i times 6i

This is not a homework problem so don't worry, more a personal observation...

Why would a go-cart with it's center of gravity closer to the front end accelerate faster than the same cart with the center of gravity near the rear given both are sent down the same hill at the same time? What forces at work would cause this discrepancy?
