Graph the solution for the following linear inequality system. Click on the graph until the final result is displayed.
S_A_V [24]

Answer:

Step-by-step explanation:

x+y>0, x>0, when y=0

x+y<-5 x<-5 when y=0

since the sign is only< then it is dotted line, and since one is greater and is less than they actually do not intersect

Answer: For the equation simply substitute 30 in for v and 4 in for s in the equation given, so H=-16t^2+30t+4

Part 2.

If the juggler misses the ball, you wish to know the time that it takes for the ball to travel the four feet from his hand to the ground, so respectively,

4=-16t^2+30t+4 or 0=-16t^2+30t or 0 = -16t+30,

solving for t, t =30/16 seconds or 1.875 seconds

Factor x^4 - 2x^3 - 33x^2 + 50x + 200 completely using the given factor x^2 - 25.
PIT_PIT [208]

You can do synthetic division twice immediately (or once if you know how to handle x^2 - 25 all at once. I'll use 2 divisions. x^2 - 25 is (x + 5)(x - 5). Both of them are zeros to the given equation which means that x = +5 and

x = - 5  are both zeros of the given quartic.

5        1      -2       -33       50         200

                 5         15       -90         -200          

=====================================

          1       3        -18       -40         0

What you have now is x^3 + 3x^2 - 18x - 40 = 0

Do another synthetic division

-5        1       3       -18       -40

                   -5       10        40

============================

           1      -2        -8        0

The result is

x^2 - 2x - 8 = 0 which factors.

(x + 2)(x - 4) = 0

Answer

The factors are (x + 2)(x - 4)(x + 5)(x - 5) = 0

Long division

x^2 + 0 + 25 ||x^4 - 2x^3 - 33x^2 + 50x + 200 ||x^2 - 2x - 8

                      x^4 + 0  +    25x^2

                      ==================

                               -2x^3 -8x^2  +  50x

                                -2x^3 + 0  +     50x

                                =================

                                            -8x^2 + 0 +200

                                            -8x^2 + 0 + 200

                                ==================
