Much appreciated! 

thanks! whats the formula for deceleration? i have driving at 25mi/hr slam on breaks, and in 3 seconds speed decreases to 8mi/hr.

thanks! i figured it out! 

find the cross product of vectors p= -2i -3j and q= 4i +7j

yea, they aren't given. so does that mean i only do the one that applies? a1b2 - a2b1?

Edit*** so it would be?
 a x b= -2 instead of a x b = 0, 0, -2?

so the formula would be 

(-3)(0) - (0)(7)

Ah, alright 

Thank you both!! 

Is something wrong CPhill? and thanks heureka!

works wonders for me. prehaps its your internet/web browser? 

In mathematics, a polynomial is an expression consisting of variables (or indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents. An example of a polynomial of a single indeterminate (or variable), x, is x² − 4x + 7, which is a quadratic polynomial.

thanks a bunch!

Thanks for the help! Appreciate it Melody! 

i do it like

AB11= 1X2, 2X-1 = 0

AB12= 1X6, 2X0  = 6

AB21= 3X2, 4X-1 = 2

AB22=-3X6 4X0 = 18

So im just wondering if i put it   0(AB11)   2(AB21)

                                              6(AB12)   18(AB22)

so would that be..

AB= 0 2     +   B= 2 6

      6 18              -1 0

sometimes i wonder if these anons are just someone talking to themselves
