Human beings did not speak the way we do now, it took years of evolution to achieve this without having the example of another animal. Will any other animal be able to achieve the same thing through evolution since a lot of them listen constantly to us talking?

im doing an essay on it

2007-01-05 15:20:30 · 1 answers · asked by Anonymous in Zoology

Find an equation of the line through the point A (4,5,5) which meets the line (x-11)/3 = (y+8)/-1 = z-4 at right angles.



Any vector, , perpendicular to <3, -1, 1> must satisfy 3a-b+ c= 0 or c= b- 3a. (I did this through dot product)


Such a line passing through (4, 5, 5) must be of the form (x-4)/a= (y- 5)/b= (z-5)/(b- 3a).

Now, what are the conditions on a and b, in order to ensure that (x-4)/a= (y- 5)/b= (z-5)/(b- 3a) intersects (x-11)/3 = (y+8)/-1 = z-4 ?

This is where i have a hard time. help
