Atruck rental company charges $50 plus $10 per hour. identify a function that represents the total charge for renting a truck for a certain number of hours. what is the value of the function for an input of 4, and what does it represent?

  c(h) = 50 +10h

  c(4) = 90 . . . . . it costs $90 to rent the truck for 4 hours

Step-by-step explanation:

The problem statement tells you the total charge is the sum of $50 and a charge of $10 per hour. That is, for h hours, the total charge is ...

  c = 50 + 10h

In functional form, this is ...

  c(h) = 50 +10h . . . . . . total charger for a rental of h hours

__

The function value with an input of 4 is ...

  c(4) = 50 +10·4

  c(4) = 90

Since the input is the number of hours of rental, and the function value is the total charge, this represents the total charge for a rental of 4 hours.

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
