The first derivative of f is given by LaTeX: f'\left(x\right)=\frac{\cos^2x}{x}- \frac{1}{5}f ′ ( x ) = cos 2 ⁡ x x − 1 5. How many critical values does f have on the open interval LaTeX: \left(0,10\right)( 0 , 10 )? Enter an integer value and 0 if no critical values.

i have no clue at all sorry

step-by-step explanation:

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

answer: no
