Determine if the matrix below is invertible. Use as few calculations as possible. Justify your answer. Choose the correct answer below. A. The matrix is not invertible because its determinant is zero. B. The matrix is invertible because its determinant is not zero. C. The matrix is not invertible because the matrix has 2 pivot positions. D. The matrix is invertible because its columns are multiples of each other. The columns of the matrix form a linearly dependent set.

Answers

Answer 1

Answer:

A. The matrix is not invertible because its determinant is zero.

Step-by-step explanation:

The matrix is invertible if the columns and rows are equal. The square matrix is invertible because it has equal rows and columns. The determinant of the matrix is zero then the matrix is no invertible.

You have different lengths of material to use for a craft project:

0.93m 1.24m 0.62m 3.41m 1.5m 1.4m

Convert each length to centimetres, and then add them together to correctly calculate the total length.

Answers

Answer:

[tex]Lengths: 93cm, 124cm, 62cm, 341cm, 150cm, 140cm[/tex]

[tex]Total := 910cm[/tex]

Step-by-step explanation:

Given

[tex]Lengths: 0.93m, 1.24m, 0.62m, 3.41m, 1.5m, 1.4m[/tex]

Required

Convert to length and calculate the total

To calculate to centimeters, we simply multiply each length to 100.

So, we have:

[tex]Lengths: 0.93m, 1.24m, 0.62m, 3.41m, 1.5m, 1.4m) * 100[/tex]

[tex]Lengths: 93cm, 124cm, 62cm, 341cm, 150cm, 140cm[/tex]

The total is:

[tex]Total := 93cm+ 124cm+ 62cm+ 341cm+ 150cm+ 140cm[/tex]

[tex]Total := 910cm[/tex]

Step-by-step explanation:

Answer:

second option:  12b²(∛2a)

Step-by-step explanation:

you can break [tex]\sqrt[3]{54a}[/tex] into [tex]\sqrt[3]{3^3(2a)}[/tex] which equals 3[tex]\sqrt[3]{2a}[/tex]

you can break [tex]\sqrt[3]{2ab^6}[/tex] into [tex]\sqrt[3]{2ab^3b^3}[/tex] which equals b²[tex]\sqrt[3]{2a}[/tex]

now we can simplify: (3b² ·  3[tex]\sqrt[3]{2a}[/tex]) + 3b²[tex]\sqrt[3]{2a}[/tex] = 9b²[tex]\sqrt[3]{2a}[/tex] + 3b²[tex]\sqrt[3]{2a}[/tex]

this equals 12b²[tex]\sqrt[3]{2a}[/tex]

the sumof the present ages of a father and his son is 60 years. 6years ago, the father's age was 5 times the age of his son.after 6 years, how old will the son be?​

Answers

Answer:

20 years

Step-by-step explanation:

Let the present ages of son and father be x and (60 -x) years respectively.

Then, (60 - x) - 6 = 5(x - 6)

54 - x = 5x - 30

6x = 84

x = 14.

Son's age after 6 years = (x+ 6) = 20 years..

Answer:

  3x +4y = -36

Step-by-step explanation:

The slope-intercept form is ...

  y = mx + b

where m is the slope and b is the y-intercept. From this equation, we can find the y-intercept as ...

  b = y -mx

For the given point and slope, this is ...

  b = -6 -(-3/4)(-4) = -9

Then the slope-intercept equation is ...

  y = -3/4x -9

We can multiply by 4 to get something we can put in standard form.

  4y = -3x -36

  3x +4y = -36 . . . . standard form equation

If 2/3z = 6, then z=

Answers

Answer:

z=9

Step-by-step explanation:

we are given: 2/3z=6

we need to find what z is by itself

6 is 2/3rds of what the value of z is.

to find z, we need to multiply both sides by 3/2 (the reciprocal of 2/3z, to make the coefficient of 1)

3/2*2/3z=6*3/2

z=9

hope this helps :)

z = 9

Step-by-step explanation:

2/3 . z = 6

2z/3 = 6

Multiple all terms by the same value to eliminate fraction denominator,

3 x 2z/3 = 3 x 6

2z = 18 ( 3,3 got cancelled)

Divide both sides of the equation by the same term,

2z/2 = 18/2

On Simplify,

z = 9.

*(2,2 gets cancelled and 18/2 = 9)

Oxaloacetate is a key intermediate in the citric acid cycle, but it is also needed as a precursor for the synthesis of glucose during gluconeogenesis. Oxaloacetate is also fairly chemically unstable and undergoes spontaneous decarboxylation to pyruvate. Although oxaloacetate is not depleted by participation in the citric acid cycle, it can become depleted by other processes, necessitating its replenishment by various synthetic pathways. Use the Metabolic Map to identify enzymes that can replenish oxaloacetate or other citric acid cycle intermediates. sarah started the school year with 14 drawings in her notebook and draws 5 more each day. whats the linear equation?
