| MMkayy.. Let me give you guys the correct answers
1)a)4
b)Integral from 0.539 to 1.675 (-2-(x^3)+4x)dx
c)No effing idea. According to stix, it is 9.987.
d)8.37
2)a)Estimate by secant line! 8 people/hour
b)155.25; I am not sure if you can use the (delta x /2)(y1+2y2+2y3...)
But 155.25 was computed by calculating the area of trapezoids of unequal width
c)3 times
d)973 tickets
3)a)67.2; Probably Less than the true value.. I don't know why
b)67.988
c)According to Stix, 2.703 or whatever *10^(-4)
4)a)t=3 x= -10
b)3
c)Speed is DECREASING since acceleration and velocity have opposite signs
d)(0,1) and (4,6) ; I don't think it matters if it's [0,1] and [4,6]
5)a)Relative minimum
b)(2,3)
c)7+3e-(e^3)
6)a)Sketch
b)105/16
c)51/8
d)(6,8] <--8 HAS TO be included |
