x^2+12x-28=0

(x+14)(x-2) = 0     therefore either  x= -14 or 2

x^1.015=200000

x=166989.68708294755

Use the calculator, Silly !

x+y*y=6

x + y^2 = 6

y^2 = 6-x

y = sqrt (6-x)       (plus or minus)

the nth term is given by:    7n + 6

A.  h'(t) = vo   +  t h''(t)   =  vo  - 9.8 t

B. h(t)   = ho  +  vo t + 1/2(-9.8) t^2

2 =  (1 + i)^27

i=2.6 percent

You'll need to clarify your question.....I think you typed it incorrectly.

#2    1                                                                          1

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

        0                                                                          0

(Re-posted with v= 4 x 10^3   NOT  NOT  4 x 103 m/s)

OK.....the y velocity is .0135/t    where t is the time it took to travel 56 cm at   (4 x 10^3m/s)  = .56/4000

.0135/ (.56/4000) = ( .0135 x 4000) /.56 = 96.429 m/s

This   velocity change from ZERO to this value occured in the time it took to cover the plate length of 26cm (.26m) at 4 x 10^3 m/s.

   .26/4000 = 6.5 x10^5 seconds

Acceleration in the y direction is thus the change in

velocity/time = (96.429)/.6.5 x 10^-5 = 1483523  m/s^2

Since F= ma    Thus the force is   1483523 ( m )

Lorentz force law :  F= q(E+ v x B) = 1483523 m    divide both sides by m

q/m (E + v x B) = 1483523

or rewritten:

q/m = 1483523/ (E + v x B)   We are given E  and v which we can substitute....but we still do not have 'B'   the magnetic flux density......hmmmmm   .... NOW I'M STUCK!    Wonder if I was given all of the information? 

Think I might be on the wrong path???
