Answer:

C. The number of items in the column list doesn't match the number in the VALUES list.

Explanation:

The INSERT INTO statement is used to insert new records in a table.

Syntax is as follows:

INSERT INTO table_name (column1, column2, column3, ...)

VALUES (value1, value2, value3, ...);

Each column item has to match with the values to be inserted in the same order.

In the question, there are 8 column items specified whereas there are only 7 values given to be inserted.

Using Matlab programming I need to rotate the line defined by x,y by 45 degrees around 2,2

belka [17]

Answer:

% here x and y is given which we can take as

x = 2:2:10;

y = 2:2:10;

% creating a matrix of the points

point_matrix = [x;y];

% center point of rotation which is 2,2 here

x_center_pt = x(2);

y_center_pt = y(2);

% creating a matrix of the center point

center_matrix = repmat([x_center_pt; y_center_pt], 1, length(x));

% rotation matrix with rotation degree which is 45 degree

rot_degree = pi/4;

Rotate_matrix = [cos(rot_degree) -sin(rot_degree); sin(rot_degree) cos(rot_degree)];

% shifting points for the center of rotation to be at the origin

new_matrix = point_matrix - center_matrix;

% appling rotation

new_matrix1 = Rotate_matrix*new_matrix;

Explanation:

We start the program by taking vector of the point given to us and create a matrix by adding a scaler to each units with repmat at te center point which is (2,2). Then we find the rotation matrix by taking the roatational degree which is 45 given to us. After that we shift the points to the origin and then apply rotation ans store it in a new matrix called new_matrix1.

A diet to contain at least 2400 units of vitamins, 1800 units of minerals, and 1200 calories two foods , Food A and Food B are t

Firdavs [7]

Answer:

30 units of Food A and 45 units of Food B are to be purchased to keep costs at the minimum $105.

Explanation:

X = Amount of food A

Y = Amount of food B

Z= 2X+Y..... minimum cost equation

50X + 20Y > 2400 .................Vitamins .......(1)

30X + 20Y > 1800 ...................Minerals.......(2)

10X + 40Y > 1200 .................Calories ..........(3)

X > 0

y > 0

X=30 and Y = 45

Z= 2(30) + 45 = $105
