PLEASE HELP ALGABRA 1 ! Russ told a friend that when he visited Canada the average temperature was 12 degrees Celsius. The Formula below shows the relationship between degrees Celsius,°C and degrees Fahrenheit, °F .

C =5/9 (F-32)

Which of these is closest to the average temperature, in degrees Fahrenheit, for Russ' visits ?

A. 39 °F
B. 45 °F
C. 54 °F
D. 79 °F

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

b i think

step-by-step explanation:

not really sure

1/800 is the right answer
