format rat

A = [-3 -2 4; -6 4 12; 6 -8 -11]

% Note: For Elementary Row Operation: Ri <- Ri + b*Rj

% E = eye(size(A)); E(i,j) = b;

% Elementary Row Operation: R2 <- R2 - 2*R1

E1 = eye(size(A)); E1(2,1) = -2

% Elementary Row Operation: R3 <- R3 + 2*R1

E2 = eye(size(A)); E2(3,1) = 2

E2E1A = E2*E1*A

% Elementary Row Operation: R3 <- R3 + (12/8)*R2

E3 = eye(size(A)); E3(3,2) = 12/8

U = E3*E2*E1*A

% Part (b)

L = inv(E1)*inv(E2)*inv(E3)

fprintf('Hence, L is a lower triangular matrix with ones on the diagonal.\n\n')

format short

A_LU = A - L*U;

disp('A - LU ='), disp(A_LU)

fprintf('Hence, A = LU.\n')

Rationalise the denominator by 6 root 7 minus 1

nikklg [1K]

Answer:

Assuming the numerator was 1.

$(6\sqrt{7}+1)/251$

Step-by-step explanation:

Assuming the numerator was 1.

$1/(6\sqrt{7} -1)\\ (6\sqrt{7}+1)/((6\sqrt{7} - 1)(6\sqrt{7} + 1))\\ (6\sqrt{7}+1)/((6\sqrt{7})^2 + 6\sqrt{7} - 7\sqrt{7} - 1)\\(6\sqrt{7}+1)/((6\sqrt{7})^2 - 1)\\(6\sqrt{7}+1)/((36*7 - 1)\\(6\sqrt{7}+1)/251$

40 POINTS!!! PLEASE HELP!!!!

vovangra [49]

Answer: They can complete the job in 1.43 hours.

Step-by-step explanation:

Let's define:

"moving a three-bedroom" as "one job"

We know that Kevin can complete one job in 5 hours, then he works at the rate:

K = (1 job)/(5 hours) = (1/5) job per hour.

Now if Q is the rate at which Quinton works and T is the rate at which Trey works, their combined rate is (Q + T), and they can complete the job in 2 hours, then:

(Q + T) = (1 job)/(2 hours) = (1/2) job per hour.

When Kevin, Quinton, and Trey wor togheter, the combined rate is:

(K + Q + T)

And we know that:

(Q + T) = (1/2) job per hour.

K = (1/5) job per hour.

If we replace these in the above sum we get:

(K + Q + T) = (1/5) job per hour + (1/2) job per hour

= (1/5 + 1/2) job per hour

= (2/10 + 5/10) job per hour

= (7/10) job per hour.

Then they need to work for T hours in order to complete 1 job, we have the equation:

[ (7/10) job/hour]*T = 1 job

T = ( 1 job)/(7/10) job/hour = 10/7 hours = 1.43 hours.

they can complete the job in 1.43 hours.

Below is a drawing of a wall that is to be covered with either wallpaper or paint. The wall is 8 ft. high and

Snowcat [4.5K]

84 sq. ft of the wall has to be covered with paint or wallpaper.

Step-by-step explanation:

Step 1: Find the area of wallpaper to be covered by calculating the area of the wall and subtracting the areas of the window, mirror and fireplace from it. All are rectangular in shape with are given by A = length × width

Area of the wall = 8 × 16 = 128 ft²

Area of the window = 18/12 × 14 = 1.5 × 14 = 21 ft² (since 1 ft = 12 in)

Area of the fireplace = 5 × 3 = 15 ft²

Area of the mirror = 4 × 2 = 8 ft²

Step 2: Calculate the area to be painted or covered with wallpaper

Area of the wall to be covered with paint or wallpaper = 128 - (21 + 15 + 8)

= 128 - 44

= 84 ft²
