For the given function f(x), the point c, and a positive number epsilon, find Upper L equals ModifyingBelow lim With x right arrow c f (x ). Then find a number delta greater than 0 such that for all x, 0 less than StartAbsoluteValue x minus c EndAbsoluteValue less than deltaright arrowStartAbsoluteValue f (x )minus Upper L EndAbsoluteValue less than epsilon. f(x)equals3 minus 4 x, cequals3, epsilonequals0.05

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

m∠a is 90°

m∠b is 40°

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour

      3   1/2 hours               3.5 hours
