Answer:

0

Step-by-step explanation:

Let the two eigen values are a and b

As we have given that trace of the matrix is 26

So a+b=26 (property of eigen value )

As the matrix is a singular matrix so the determinant of the matrix will be zero

So ab =0 ( property of the eigen values)

For ab =0 any one of the eigen value must be 0

If one eigen value will be zero then other will be 26

So the smaller eigen value will be zero

DerKrebs [107]

Answer:

Hi. so I don't have the answers but usually if you find the name of the website your homework is from (if should be at the bottom of the page) online you can also find the answers for it. Just letting you know for this homework and future references.

Step-by-step explanation:

If the teacher asks for you to show your work the website might not show you step by step but you can just say you did it on a separate page. hope this helps!

The Smelting Department of Kiner Company has the following production and cost data for November. Production: Beginning work in
zhenek [66]

Answer:

a. 16000 units

b. 11800 units

Step-by-step explanation:

A.

To get equivalent units of production for materials

Add up the units transferred out + ending work in progress

= 9000 units + 7000 units

= 16000 units

B.

To get conversion cost for November:

Units that are transferred out + (ending work in progress * % of conversion)

= 9000 + (7000 x 40%)

= 9000 + 2800

= 11800 units

The answers are therefore

1. 16000units

2. 11800 units

If h(2)=7 and h'(2)=-2,find d/dx [(h(x))/(x)] <br> A. –11/4 B. 2 C. D. 8 E. 16
valentinak56 [21]

Answer:

A. \frac{-11}{4}

Remember that if f and g are functions with g(x)\neq 0 then, \frac{d}{dx}\frac{f(x)}{g(x)}=\frac{f'(x)g(x)-g'(x)f(x)}{g(x)^2}.

Then,

\frac{d}{dx}\frac{h(x)}{x}=\frac{h'(x)x-h(x)}{x^2}

Evaluating in x=2,

\frac{h'(2)*2-h(2)}{2^2}=\frac{-4-7}{4}=\frac{-11}{4}

Then the answer is A.

Which zero pair could be added to the function f(x)=x2 +12x+6 so that the function can be written in vertex form
Gnom [1K]

The most general proccedure for this type of problems is the following:

For a quadratic function of the following form f(x)=x^2+bx+c; where b and c are real numbers.

1) Identify the value that accompanies the x, that is, the value "b"

2) Divide the value of b by 2 and then square it: (\frac{b}{2})^2

3) Add and subtract in the function the value of  (\frac{b}{2})^2

4) Write the complete function of the form f(x) = (x+\frac{b}{2})^2-(\frac{b}{2} )^2+c

For the function presented f(x)=x^2 +12x+6 the result is as follows:

1) The value of b is 12

2) (\frac{12}{2} )^2=36

3) f(x)=(x^2+12x+36)-36+6

4)f(x)=(x+6)^2-36+6

Finally the function is:

f(x)=(x + 6)^2-30


The zero pair that must be added is 36 and -36
