define the linear transformation t by t (x) = ax. find (a) ker(t ), (b) nullity(t ), (c) range(t ), and (d) rank(t ). a = 1 −2 −3 1 5 3 −1 1 0 4 1 1 3 1 2

Answers

Answer 1

We  have:

(a) ker(t) = {(x1, x2, x3, x4) | x1 = 3x3, x2 = -x3, x4 = t, where t is any scalar}

(b) nullity(t) = 1

(c) range(t) = span{(1, 1, -1), (-2, 5, 1), (-3, 3, 4)}

(d) rank(t) = 3

To find the kernel of the linear transformation, we need to find all vectors x such that t(x) = ax = 0. This means we need to solve the system of linear equations:

x1 - 2x2 - 3x3 = 0

x1 + 5x2 + 3x3 = 0

-x1 + x2 + 4x3 + x4 = 0

3x1 + x2 + 2x3 + x4 = 0

Putting this system into reduced row echelon form, we get:

1 0 -3 0

0 1 1 0

0 0 0 1

0 0 0 0

The pivot columns are 1, 2, and 4. So, the basic variables are x1, x2, and x4, while x3 is a free variable. So, the kernel of the linear transformation is given by:

ker(t) = {(x1, x2, x3, x4) | x1 = 3x3, x2 = -x3, x4 = t, where t is any scalar}

Therefore, the dimension of the kernel or nullity of t is 1, since there is only one free variable.

To find the range of the linear transformation, we need to find all vectors y such that y = t(x) = ax for some vector x. This is the span of the columns of the matrix A, which can be found by row reducing A to get:

1 0 0 0

0 1 0 0

0 0 1 0

0 0 0 0

The pivot columns are 1, 2, and 3, so the corresponding columns of A form a basis for the range of t. Therefore, the range of t is:

range(t) = span{(1, 1, -1), (-2, 5, 1), (-3, 3, 4)}

which has dimension 3. Thus, the rank of t is 3.

Therefore, we have:

(a) ker(t) = {(x1, x2, x3, x4) | x1 = 3x3, x2 = -x3, x4 = t, where t is any scalar}

(b) nullity(t) = 1

(c) range(t) = span{(1, 1, -1), (-2, 5, 1), (-3, 3, 4)}

(d) rank(t) = 3

What must you subtract from the expression –5x – 8 in order to make it equivalent to –9x – 1 for all values of x?

Answers

Answer:

the number is 4x - 7

Step-by-step explanation:

Let P be subtracted from -5x - 8 to make it equivalent to -9x - 1.

-5x - 8 - P = -9x - 1

make "-P" the subject of the formula

-P = -9x - 1 + 5x + 8

Collect like terms;

-P = -9x + 5x  - 1 + 8

-P = -4x + 7

divide through by "-1"

P = 4x - 7

Therefore, the number that must be subtracted from -5x - 8 to make it equivalent to -9x - 1 is 4x - 7

Shown is a square garden with a triangular pond.
Find the area of the garden that is grass

Answers

Area of the square:
6x6 = 36m^2
Area of the triangle
3x4/2=6m^2
Area of grass
36-6=30m^2

The area of the garden that is grass is 30 square meters.

The square garden has a side length of 6 meters.

The triangular pond has a base of 4 meters and a height of 3 meters.

The area of the garden that is grass.

The area of the square garden is 6 x 6 = 36 square meters.

The area of the triangular pond is (1/2) x 4 x 3 = 6 square meters.

Therefore, the area of the garden that is grass is 36 - 6 = 30 square meters.

The area of the garden that is grass is 30 square meters.

Here are the steps in detail:

Calculate the area of the square garden: 6 m * 6 m = 36 square meters

Calculate the area of the triangular pond: (1/2) * 4 m * 3 m = 6 square meters

Subtract the area of the pond from the area of the square to find the area of the grass: 36 square meters - 6 square meters = 30 square meters

find the LCM of 3,6,2,4

LCM = 12

THEREFORE,

2/3*4/4 = 8/12

5/6*2/2 = 10/12

1/2*6/6 = 6/12

3/4*3/3 = 9/12

8/12 , 10/12 , 6/12 , 9/12

Ascending order of ( 8/12 , 10/12 , 6/12 , 9/12)

= 6/12 , 8/12 , 9/12 , 10/12

So, 6/12 = 1/2

8/12 = 2/3

9/12 = 3/4

10/12 = 5/6

THEREFORE

Ascending order = 1/2 , 2/3 , 3/4 , 5/6

Answers

Answer:

If 20 more soldiers join it would last 48 days

Step-by-step explanation:

if 80 soldiers need 84000 food for 60 days it means that in 60 days one soldier eats 84000/80= 1050 each

then 1050/60=17.5 meaning they need 17.5 food a day each,

adding 20 soldiers means 80+20= 100 soldiers

100*17.5=1750 food is eaten every day

84000/1750= 48 which means that 100 soldiers will eat 84000 in 48 days
