Answer
Domain is the values x can be.
Range is the values y can be.
1st Graph)
D: -8 < x < 3
R: 3 < y < 9
2nd Graph)
D: -4<x<4
R: -4<y<4
3rd Graph)
-Note that this graph has an open and closed circle. Which means one is open and the other is closed on the interval. I will use brackets to make it easier.
D: [-4,3)
R: (-6,2)
Answer: 349 square units
============================================
Work Shown:
- L = 5.5 = length
- W = 5 = width
- H = 14 = height
SA = surface area of rectangular prism
SA = 2*(L*W + L*H + W*H)
SA = 2*(5.5*5 + 5.5*14 + 5*14)
SA = 2*(27.5 + 77 + 70)
SA = 2*(174.5)
SA = 349
The surface area is 349 square units.
Since 13,687 vehicles will fit on 14 1,000-space parking lots we have:
14*1,000 = $14,000 will be the cost to lease enough lots to accommodate an overflow of 13,687 vehicles.
