Step-by-step explanation:

The question is incomplete. Here is the complete question

Matrices C and D are shown below:

[tex]C=\left[\begin{array}{ccc}2&1&0\\0&3&4\\0&2&1\end{array}\right][/tex]     [tex]D=\left[\begin{array}{ccc}a&b&-0.4\\0&-0.2&0.8\\0&0.4&-0.6\end{array}\right][/tex]

What values of a and b will make the equation CD = I true?

(i) a = 0.5

  b = 0.1

(ii) a = 0.1

    b = 0.5

(iii) a = -0.5

    b = -0.1

Answer: (i) a = 0.5

                  b = 0.1

Step-by-step explanation: Identity Matrix (I) is a n x n square matrix with the number 1 on the main diagonal and 0 everywhere else.

The question asks for multiplication of matrices, i.e.:

[tex]\left[\begin{array}{ccc}2&1&0\\0&3&4\\0&2&1\end{array}\right][/tex]  .   [tex]\left[\begin{array}{ccc}a&b&-0.4\\0&-0.2&0.8\\0&0.4&-0.6\end{array}\right][/tex] = [tex]\left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right][/tex]

To multiply matrices, the number of columns of the 1st matrix must be the same as the number of rows of the 2nd.

Matrix C is a 3x3 square matrix and so is matrix D, so, values of a and b:

[tex]2a=1[/tex]                           [tex]2b-0.2=0[/tex]

[tex]a=\frac{1}{2}[/tex]                            [tex]2b=0.2[/tex]

a = 0.5                          [tex]b=0.1[/tex]

For the equation CD=I be true, a and b has to be 0.5 and 0.1, respectively.

Answer:

2x(5x + 14) + 15

Step-by-step explanation:

Given: (2[tex]x^{2}[/tex] + 3)(4x + 5) - 8x([tex]x^{2}[/tex] - 2)

(2[tex]x^{2}[/tex] + 3)(4x + 5) - 8x([tex]x^{2}[/tex] - 2) = 2[tex]x^{2}[/tex](4x + 5) + 3(4x + 5) - 8x([tex]x^{2}[/tex] - 2)

                              = (8[tex]x^{3}[/tex] + 10[tex]x^{2}[/tex] + 12x + 15) - 8[tex]x^{3}[/tex] + 16x

                              = 8[tex]x^{3}[/tex] + 10[tex]x^{2}[/tex] + 12x + 15 - 8[tex]x^{3}[/tex] + 16x

collecting like terms to have,

8[tex]x^{3}[/tex]- 8[tex]x^{3}[/tex] + 10[tex]x^{2}[/tex] + 12x + 16x + 15

10[tex]x^{2}[/tex] + 28x + 15

Thus,

(2[tex]x^{2}[/tex] + 3)(4x + 5) - 8x([tex]x^{2}[/tex] - 2) = 10[tex]x^{2}[/tex] + 28x + 15

                                           = 2x(5x + 14) + 15

Answer:

50º & 40º

Step-by-step explanation:

complementary anlges add up to 90º. so, we can make an equation:

x+x-10=90

2x=100

x=50

so the angles are 50º and 40º.

Answer:

4 miles per hour

Step-by-step explanation:

Total miles = 1/2

Time taken = 1/8

Miles per hour = 1/2 ÷ 1/8

= 1/2 × 8/1

= 8/2

= 4 miles per hour

Bryan’s mile per hour = 4

4 miles per hour

Answer:

Step-by-step explanation:

Let the volume of 25% ethanol be x, then volume of 85% ethanol will be (20 - x)

The ethanol content is:

11.67 gallons of 25% ethanol and

20 - 11.67 = 8.33 gallons of 85% ethanol

Answer:A) 2 months

Step-by-step explanation:The base fee is $20.

The monthly rate is $30.

We can represent the number of months with the variable ‘x’.

The equation for this problem would look like this: 20+30x=80l

In words, it would be: base fee + monthly rate*x = $80

A music shop charges a deposit of $20, plus a monthly rate of $30 to rent an instrument. For how many months did Avi rent an instrument. For how many months did Avi rent an instrument if he spent a total of $80

A) 2 months

B) 3 months

C) 4 months

D) 5 months

He can buy 2857 cars.

Step-by-step explanation:

In order to find the amount he can buy, you need to divide 1,000/.35. This equals 2857.14 but because you cannot buy .14 of a toy car, you round down to 2857 which is the end answer. Hope this helps :)

  t = (u -v)/2

Step-by-step explanation:

Observe what is done to t:

Undo these operations, starting with the last one and working up the list.

  [tex]u = v+2t \qquad\text{given}\\\\u-v=2t \qquad\text{undo addition by subtracting $v$}\\\\\dfrac{u-v}{2}=t \qquad\text{undo multiplication by dividing by 2}\\\\\boxed{t=\dfrac{u-v}{2}}[/tex]

Answer:

[tex]u = v + 2t \\ u - v = 2t \\ t = \frac{(u - v)}{2} [/tex]
