See the attached drawing for a visual.
Since we know that AC = CB is half the length of AB, we can write that in equation form. The goal is to determine the length of 
Now that we know the value of 
, we can find the value of 
:
Here's the equation for one year:
1000 + 0.08(1000)
But because it is 9 years:
1000 + 9(0.08(1000))
1000 + 0.72(1000)
We can make it simpler:
1.72(1000)
Multiply:
1720
You will have $1720
Answer: 337
Step-by-step explanation:
The volume will be the product of the end area and the length of the greenhouse.
The end area consists of 4 triangles and 6 rectangles. This fact is very important.
We can divide half of the greenhouse face along its vertical lines to make two trapezoids. The bases are the length of the vertical lines, and their heights will be respectively 2.2 m and 0.8 m.
Since there are two of each, we can find the end area to be ...
A = 2(1/2)(b1 +b2)(h1) +2(1/2)(b2 +b3)(h2)
A = (4.1 + 3.3)(2.2) +(3.3 + 1.1)(0.8) = 19.8 square meters
V = BH
V= 19.8(17)= 336.6 m^3 which is rounded to 337
Therefore, we have used area to determine the volume. :)
I hope this helps!
The answer will be (-8,-4)
