Answer:
12
Step-by-step explanation:
8x1+8x0.5
8+4
12
12$ is the total cost
Easy :).
Remove the flat rate to see how much money she has to spend: 10 - 1.95 = 8.15.
We have 8.15 (remaining money) / 0.60 (per mile) = 13 miles (or <span>13.5833333333 [copy pasted from a calculator moderators] but I assume you want a rounded version)</span>
Put the number of Canolis (maybe the bottom) on one side and time (maybe the left) on the other and start the graph at 12 then fast forward 3 hours and 60 and draw a line between 12 and 60 then do 6 hours at 132 and keep the straight line... the function is a table made from the results of this graph
The formula for arithmetic sequence is given by:
an=a+(n-1)d
where:
an=nth term
a=first term
n=number of terms
thus our first term will be:
a1=8
a2=8+(2-1)(-6)=2
a3=8+(3-1)(-6)=-4
a4=8+(4-1)(-6)=-10
a5=8+(5-1)(-6)=-16
a5=-16
thus the sequence will be:
8,2,-4,-10,-16...


notice... the dog's pen perimeter, does not include the side that's bordering the garden's, since that side will use the heavy duty fence, instead of the light one
so, the sum of both of those costs, will be the C(x)

so, just take the derivative of it, and set it to 0 to find the extremas, and do a first-derivative test for any minimum
