There are 16 oz in a pound
a) 1.92 / 16 = $0.12 per oz
b) 3.52 / (16 x 2) = $0.11 per oz
c) Meat 2 is the better buy since it is cheaper
<span>y = tan^−1(x2/4)</span>
tan(y) = x2/4
sec2(y) = x/2
y′ = xcos^2(y)/2
<span>cos^2(y) = <span>16x2+16</span></span>
<span>y′ = <span>8x/(<span>x2+16)
let u be x2+16
du is 2x dx
dy = 4 du / u
y = 4 ln (</span></span></span>x2 <span>+ 16)
y at x =0 = </span> 4 ln (<span>16) = 11.09</span>
Rewrite it from least to greatest and set it up like shown
By applying 2×pie×radius (radius+height)
