If F= 2i-3j , and if the moment vector of F about B (1,4) equals 16 k

find the equation of the action line of F .

Sorry can't write in LaTex

Help appreciated

Liquid is leaking from a small hole in a vessel full with the liquid. The volume of the liquid changes at the rate of (0.4t-40)cm³/sec.

find:

1- The volume of the vessel

2- When the vessel becomes empty?

given that the volume of the liquid was 980cm³ after 30 seconds from the start of leaking.

PLEASE Explain your answer and if you can give me guide steps to solve problems like this '

MANY THANKS in Advance:D.

help me solve this limit probem

many thnx highly appreciated

but with -2 it did Is this the right reason???

multiply it by the conjugate then divide each term under the cubic root by x^3 and out the root by x

sorry for bothering you I just wanna know which solution is right MANYYYY Thnx

Actually I didn't study it that way am in high school so we learn only headlines Thnx 4 ur help

If , rate of change of this function =-3/4 at x=4 , and the average rate of change =-5/6 when x changes from 4 to 3.8 ,

FIND the values of a and b.

THNX in advance

Without using calculator:

prove that:

my Mr solved it for me today

F(x)=x^2-x+1/(x+1)(x^2-x+1)=1/x+1

http://www.mathsisfun.com/data/function-grapher.php?func1=(x^2-x-1)/(x^3+1)&xmin=-12&xmax=12&ymin=-8&ymax=8

Domain=R-{-1}

Range=R-{0}

Decreasing in (-∞,∞)-{-1}

am very sorry for that stupid mistake i had made

Tx bobbym
