P(-2)= 6(-2)3-(-2)2+29(-2)-46
= -36+4-58-46
=-140+4=-136
Remember the slope equation!
y2-y1/x2-x1
1.) 5-0/1-0
slope=5
2.)4-2/6-3
slope= 2/3
3.)3-0/4-0
slope: 3/4
4.)2.5-(-2.5)/1-(-1)
slope=5/2
The perimeter (IP) of a rectangle is
P = 2(length + width)
let width = w then length = w + 88
P = 2(w+w+88) = 2(2w+88) = 4w+176
Thus P = 4w+176 = 7272
hence 4w = 7272 - 176 = 7096
so w = 7096/4 = 1774
width = 1774 inches and length = w+88 = 1774+88 = 1862 inches
-4,-3,-2,-1,0,1 those are the six consecutive integers starting with -4
To simplify things, one could just use differentiation with exponents.
y= 1/(p +ke^p)= (p + ke^p)^-1
dp/dy = -1 - ke^p
