veronica works each day and earns more money per hour the longer she works. write a function to represent a starting pay of $20 with an increase each hour by 5%. determine the range of the amount veronica makes each hour if she can only work a total of 8 hours.

20 ≤ x ≤ 28.14
20 ≤ x ≤ 29.55
20 ≤ x ≤ 26.80
20 ≤ x ≤ 25.53

The range of the amount Veronica makes each hour if she can only work a total of 8 hours is 20 ≤ x ≤ 29.55

Solution:

Let us assume that Veronica worked x hours

The starting pay is

Each hour increase is

So the function is

Now if she works 8 hours, she will earn,

So, the range will be 20 ≤ x ≤ 29.55

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
