x² + 5x - 6 can be expressed as (x + 6)(x - 1).
<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>
The thing is that every 4 years, the tree grows 6 inches, so that could be expressed as a ratio, 4/6. That also means that every two years, the tree grows 3 inches since it could be simplified to 2/3.
1 inch = 25 miles so 5inches x 25 = 125 miles
