Mathematics
1 answer:
Irina-Kira [14]3 years ago

Answer:

b. 5x6

Step-by-step explanation:

Since we know that in order for a matrix multiplication to be defined, the number of columns in the first matrix must be equal to the number of rows in the second matrix.

We have been given the dimensions of a matrix as: 3 by 5, which means that the number of rows in the given matrix is 3 and number of columns is 5.

In order to multiply our matrix F with another matrix, the number of rows in the another matrix must be equal to 5.    

Now let us see our given choices one by one.

a.  3x5

Upon looking at our first option we can see that number of rows in this matrix is 3 and number of columns of our matrix F is 5. 3 is not equal to 5, therefore, option a is not a correct choice.

b. 5x6  

Number of rows of the matrix provided in option b is 5 and number of columns of our matrix F is also 5, therefore, option b is the correct choice.

c. Since we know that multiplication of matrices is possible with compatible dimensions, therefore, option c is not a correct choice.  

d. As we already found our correct option, therefore, 'none of the choices work' is not a correct choice.

Find expressions for the partial derivatives of the following functions:
nlexa [21]

Answer:

Step-by-step explanation: partial derivative is the differentiation of one variable e.g. X while leaving the values of the other variable e.g. Y

These four questions A, B, C and D have different functions separated by commas. I will not assume the commas to be something else like a plus sign.

A. f(x) = g'(x).k(y) , g'(x) + h(y)

f(y) = k'(y).g(x) , g(x) + h'(y)

B. f(x) = g'x (x+y)

f(y) = g'y (x+y) , h'y (y+z)

f(z) = h'z (y+z)

C. f(x) = f'x (xy) , f'x (zx)

f(y) = f'y (xy) , f'y (yz)

f(z) = f'z (yz) , f'z (zx)

D. f(x) = f'x (x) , g'(x) , h'x (x,y)

f(y) = h'x (x,y)

These are the partial derivative expressions for each variable in each function. You will need to pay a lot of attention to understand:

* while differentiating X alone, functions in Y which are separated by commas from the functions in X, are ignored totally because they are different questions

* In functions where X added to Y is in a bracket e.g. (x+y), to find the derivative of X, Y isn't thrown away because they are joined (by a plus sign) the derivative of X alone in this case would be f'x (x+y)

* f(x), just like g(x), simply means/represents a function in X hence f'(x) means the differentiation of all X-terms in that function
