The equation is f(t)=5+96t-16^2

The answer the book gets is 149. How was that determined?

Thanks in advance

**I know I've asked it a couple of times but I messed up and the answers are wrong. •The one who answered both- thanks so much but they did not make sense. I NEED situations.

•How many lines are determined by four points? Consider the situations:all four points are collinear&where three of the four points are collinear. Are there other possible situations?
•I understand what to do... but not exactly how to do it. I am going to ask my teacher for help but... I need the answers for that day so help if you can, thanks so much.

Determine it: 1) where the four points are collinear -and- 2) where three of four points are collinear.
*other possible situations- yes, but what are they? I definitely need to know that part...
•I know that if there are 4 collinear points, then that is one line, because a line continues in each direction.
•Then if it is 3 out of 4 points that are collinear, would it be no line? Wouldn't they just be segments and rays? I NEED the other situations. Thanks.

Hi, I was wondering if there was any specific strategy to factor equations, for example, x²-5x+4=0. If anybody could go through step by step and explain to me how I could factor other equations similar to this easily, I would greatly appreciate it.

lim (sqrt(9x^2+x)-3x) as x-->infinity

ok I know the answer already is 1/6
but I am unsure how they got that.
if you square it you get 9x^2-6xsqrt(9x^2+x)+9
if that is correct what do you do know? Square it again? to eliminate the sqrt once more?

Hey all, well i am in a bit trouble because i don't seem to understand vector subtraction. OK here it is:
V1 = -5i + 2j
V2 = -3i -9j

Now what i get is -8 and -7.But then i need to use the Pythagorean theorem to find sides on my triangle on the graph that i have. Since the number is negative i can't swuare root the last digit of the pothagorean theorem. WHat am i doing wrong,
