(as shown in the attached image)

(a)for all 3×3 upper triangular matirices U, verify that U2 is also upper triangular

for a matrices U (having a 3*3 matrix), assuming for example, U is given below:

U = \left[\begin{array}{ccc}1&2&3\\0&5&6\\0&0&9\end{array}\right]

the element in the upper triangular are 1,2,3,5,6,9 (U₁₁, U₁₂, U₁₃; , U₂₂, U₂₃, U₂₂)

while lower triangular are 0,0,0, the element in the lower triangular are (U₂₁, U₃₁,U₃₂)

In percent of change what is 27 to 36 plz help
Novay_Z [31]
If your "original" number is 27, this is the work:
percent change = change/original * 100
percent change = (36-27)/27 * 100
percent change = 9/27 * 100
percent change = 1/3 * 100
percent change = 33 1/3
