Thats just asking the perimeter... 120 + 120 + 53 + 53 = 346 yards
What is the proportion?
<span />
If they use (20-20x0.15)+(20-20x.015)x0.05 the final cost would be $34.05
Hope this helps
Do you know how to graph the equation 2x-1?
If you do then graph it.
After, check the inequality - it is Y is less than the equation so you will be filling in everything below the line you graphed
IF you don't know how to graph:
You will have a line that goes up 2 then right 1
The equation is really 2/1 x as in 2 right 1 right
The line will start from y=-1 or 1 right below 0,0 because of the -1 at the end of the equation and the line will travel in both direction for infinity (Or as big as the graph is)
So start at y=-1 then go up 2, right 1 and place a point. Keep doing that (down 2 left 1 when going in the opposite direction) Finally just make a line through all those points you made
Answer:
The signa notation to represent the first five ten f(x) is given by 
Step-by-step explanation:
Given sequence is -5, -9, 13...
Let f(x) be the given sequence and is denoted by
Let the first term be 
term be 
ie, 
To find the common difference d:
Therefore the common difference d is -4 for given sequence f(x) with 
and d=-4, the seqence f(x) is an arithmetic sequence
By defintion of arithmetic sequence
Now to find 
:
put n=4 in equation (1)
[since a=-5, d=-4]
in equation (1)
[since a=-5, d=-4]
Therefore and
Therefore 
Now to represent the sum of the first five terms of f(x) using sigma notation as below
where
