Step-by-step explanation:

Ratios can be written as:

a to b

a:b

a/b

We want to find boys to girls, and there are 24 boys and 12 girls. So, we can write it as

24 to 12

24:12

24:2

All of these can be reduced, since both the numerator and denominator can be divided by 12.

Numerator: 24/12=2

Denominator: 12/12=1

2 to 1

2:1

2/1

a company has two packaging machines in a unit, each with a different daily capacity. the capacity of machine 1 is defined by th
Licemer1 [7]

The required function C (m ) which represents the combined capacity of the two machines is c(m) = 2m^2 + 104m + 1704

What are functions?

  • A connection between a collection of inputs and outputs is known as a function.

The given functions are:

f(m) = (m+40)^2 + 10 \\and\\g(m) = (m+12)^2 - 50

C(m) = f(m) + g(m)

Expanding the two square brackets in the following manner to calculate that sum:

f(m) = (m+40)^2 + 10 = m^2 + 80m + 1600 + 10 = m^2 + 80m + 1610\\g(m) = (m+12)^2 - 50 = m^2 + 24m + 144 - 50 = m^2 +24m + 94

f(m) + g(m) = 2m^2 + 104m + 1704

Therefore, function C (m ) which represents the combined capacity of the two machines is c(m) = 2m^2 + 104m + 1704
