Hint: show that k(-x) = h(x). Then it follows that k is the reflection of h in the y-axis. If we were looking at odd degree polynomial functions with the same structure, you would find that k(-x) = -h(x), and that k is the reflection of h in the origin (or h...

Since the object is moving at a constant speed of 2m/s, there is zero net external force. Additional 1N is applied. 1 = ma = 2a ==> a=1/2 Vf = Vi +at = 2 + (1/2)*3 = 7/2 m/s

so further sales = 13520 - (4000+6000) =3520 So income = (0.05)(4000)+(0.06)(6000)+(0.1)(3520) =200+360+352 =912 you were correct mustafa, is not right as he made 3520, 3250 easy mistake to make on a computer!

Part b) At least one GREEN = 1 - P(all RED) P(all red) = 6*5*4 / (10 *9 * 8) = 30/90 * 1/2 = 1/6 P(at least one green) = 1 - 1/6 = 5/6 Note: P(at least one RED) = 1 - P(all green) = 1 - 1/30 = 29/30 M3's other answers...
