A rhinoceros is at the origin of coordinates at time t1=0. For the time interval from t1 to t2 = 12.5 s, the rhino's average velocity has x-component -3.5 m/s and y-component 4.9 m/s.

at time t2= 12.5 s what is the x-coordinate of the rhino?
At time t2= 12.5 s what is the y-coordinate of the rhino?
How far is the rhino from the origin?

find the equation of the line through the point (1, -6) and which is parallel to the line 3x + 2y - 4 = 0


i cant get this. i found out the slope of 3x + 2y - 4 = 0 which is -3. so the slope of this line must be that.
but when i try to verify if (1, -6) is on the line, i don't get an answer of 0, i get 13.

could anyone help me out? thanks

Are we alone in the universe? What does this form of life look like? Do they look like anything on this earth? Are they more or less advanced than we are? How come nobody knows this answer? Did God make this earth in such a fashion that we are not supposed to know how the galaxies originated, where life began, if there are other forms elsewhere, etc.?

Woke up at 4.40 and saw the brightest star I've ever seen around 30 degrees NNe. It wasn't moving - so it was either a star or a planet in a near earth orbit. And will it be there again tonight? Notice that question has already been posted - but with inconclusive answer.

My friends and I found a spider on the outside brick wall and it was really big! It was about the width of the brick and it was black and white striped on it's large abdomen. On the underside it had the same pattern but yellow and black. I live in mid-western MN and one of the people I was with said she had never seen a spider like that in her life. (she's 40!) I looked all over the iternet and can not find anything the resembles this spider! Please tell me if you know anything!

2. Do you feel that this particular environmental law outweighs the costs?

3. Has this environmental law improved the environment/situation?

I've developed a rather large and uncomfortable growth just between my liquid & solid dispensers and I just can't seem to get it to go away. So far, I've been sticking to a solid regiment of Preparation H and prayer therapy, but it just keeps getting bigger and bigger. My husband has recommended I go see Benny Hinn, but I thought I'd check with the medical community first. Do you think his prayers will heal me any faster than my local pastor's will? I'm asking you all because you all know facts and stuff, so you should know whos prayers work the best. Thanks in advance!
