The range of a function is the set of possible values that can be obtained from the dependent variable. The range of the function is: 
Given that:
Let the number of months be t. So, the function C(t) is calculated as follows:
The range is calculated as follows:
The smallest possible value of t is 0 i.e. when no monthly subscription is done.
So, we have:
And the highest is 
i.e. for a large value of t
So, we have:
Hence, the range of the function is:

Answer:
Every 18 miles he uses 3 gallons
divide this:
18 ÷ 3 = 6 miles per gallon
30 miles = 30 ÷ 6 = 5 gallons
7 gallons = 7 x 6 = 42 miles
48 miles = 48 ÷ 6 = 8 gallons
10 gallons = 10 x 6 = 60 miles
Hope this helps :D
Answer:
The equation of straight line is x = 1
Step-by-step explanation:
<u>Step </u>:-
The equation of straight line having slope 'm' and passing through the point
is 
Slope of horizontal line(that is x-axis) is m = 0
slope of vertical line (that is y-axis) is m is not defined
The equation of straight line having slope is not defined and passing through the point (1,7).
cross multiplication we will get equation
x-1 = 0
The equation of straight line is x = 1
A regular quadrilateral prism has 12 edges. It is given perimeter of the base 32 cm. Length of each edge of base will be 32÷4=8 cm. The 4 edges at the top will also have the same number of edges that is 4 with measure 8cm each.
Given: The height of the prism is 2 times greater than the length of the base edge.Height of prism = 2(8)= 16cm. Number of edges with measure 16 cm is 4.
Sum of all the 12 edges= 8+8+8+8+16+16+16+16+8+8+8+8=128 cm.
