OMG, INEED HELP HELP HELP!The temperature went up by 5 ^{\circ}5 ∘ \mathrm{C}C, then down by 3 ^{\circ} \mathrm{C}3
∘ C, and finally an increase of 9 ^{\circ} \mathrm{C}9
∘ C, ending up at a temperature of 37 ^{\circ} \mathrm{C}37
C. What was the starting temperature?​

To diagonalize an nxn matrix a means to find an invertible matrix p and a diagonal matrix d such that a pdp d p ap or [1 3 dh epap 3 let a=-3 -5 -3 3 3 1 step 1: find the eigenvalues of matrix a "2's" step 2: find the corresponding eigenvectors of a step 3: createp from eigenvectors in step 2 step 4 create d with matching eigenvalues.
