Haley pays a monthly fee of $20 for her cell phone and then pays 5 cents per minute used. the cost of haley’s cell phone bill can be expressed by the function c(m) = 0.05m + 20, where m is the number of minutes used. what are the domain and range of the function c(m)?

Domain =

Range =

Step-by-step explanation:

We are given,

The cost of the phone bill is represented by the function,

, where m = number of minutes used.

Now, as 'm' is the number of minutes used. So, they cannot be negative.

Thus, the domain of the function is .

Further, when m= 0, then i.e. C(0)= 20.

Thus, the range of the function is .

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
