AleksandrR [38]

Answer:

U₂₁ and U₂₂ fits in the line of upper triangular

Step-by-step explanation:

As explain in the question

An upper triangular matric is square matrix with all zeros below its daignal. A lower triangular matrix is a square matrix with all zeros above its diagonal.

(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)

U₂₁ and U₂₂ fits in the line of upper triangular

What is the simplest form of
11111nata11111 [884]

Answer:

  1. 15 = -3c +12
  2. -3n +8 = -7
  3.  5z -40 = 10
  4. 3.4s -35 = 50

Step-by-step explanation:

Usually, you're asked to "simplify" an equation, meaning that you eliminate parentheses and combine like terms. Asking for "simplest form" suggests something different. The simplest form is the form that has the variable equal to a constant--the solution, in other words.

We suspect you want the <em>simplified form</em>, but since you asked for the <em>simplest form</em>, that is here, too.

__

1. 15=-3(c-1)+9

  15 = -3c +3 +9

  15 = -3c +12 . . . . . simplified form of the given equation

  -1 = c . . . . . . . . . . "simplest" form

__

2. 2(1.5n+4)-6n=-7

  3n +8 -6n = -7

  -3n +8 = -7 . . . . . . simplified form of the given equation

  n = 5 . . . . . . . . . . . "simplest" form

__

3. 2(z-20)+3z=10

  2z -40 +3z = 10

  5z -40 = 10 . . . . . . simplified form of the given equation

  z = 10 . . . . . . . . . . "simplest" form

__

4. 2/5s -2+3(s-11)=50

  0.4s -2 +3s -33 = 50

  3.4s -35 = 50 . . . . simplified form of the given equation

  s = 25 . . . . . . . . . . "simplest" form
