BARSIC [14]
From your work on parts (a) and (b), you know that
.. r = 3.50
.. s = 140
The composite index of production cost from 2007 to 2009 is 114.2.

(c) If the production cost in 2007 was RM50, then in 2011 it was
.. RM50 * (2009 index) * (2011 index) = RM50 * 1.142 * 1.200 = RM68.52

Answer:

The slope of f(x) is 10 and the slope of g(x) is 5; g(x) has the greater y-intercept.

To find the slope of f(x), we use the slope formula:  m=(y₂-y₁)/(x₂-x₁) = (-1--11)/(0--1) = (-1+11)/(0+1) = 10/1 = 10.

To find the slope of g(x), we just look at the form it is in.  It is written in slope-intercept form, y=mx+b, where m is the slope.  The number in g(x) that would correspond to m is 5.

The y-intercept of f(x) is found by looking at the points.  Any y-intercept will have an x-coordinate of 0; the only point like this in the table is (0, -1) so the y-intercept is -1.

For g(x), we again look at the form y=mx+b.  The number that corresponds with b is the y-intercept; in this case, it is 1.  1>-1, so g(x) has the larger y-intercept.

Answer:

V' = 900\pi in^{3} /sec

Step-by-step explanation:

V = \frac{1}{3} \pi r^{2}h

V' = \frac{2\pi rh *r'}{3}  + \frac{\pi r^{2} *h'}{3} (using differentiation product rule)

plug known values in for r, h, r', and h'

V' = \frac{2\pi (10)(40)(4)}{3} + \frac{\pi (10^{2} )(-5)}{3}

V' = \frac{3200\pi }{3} - \frac{500\pi }{3} \\V' = \frac{2700\pi }{3} \\

V' = 900\pi in^{3} /sec
