Given the following list of numbers: 90 8 7 56 123 235 9 1 653 trace the execution for: (a.1) selection sort (only the first 5 steps) (a.2) mergesort. (b) given the following list of numbers: 3 1 4 1 5 9 2 6 5 3 5 trace the execution for quicksort with median-of-three partitioning and a cutoff of 3.

a

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
