Answer: 9.6 units
<u>Step-by-step explanation:</u>
The formula for the length of a diagonal (d) for a rectangular prism given length (L), width (w), and height (h) is: d² = L² + w² + h²
Given: L = 8, w = 2, h = 5
d² = 8² + 2² + 5²
d² = 64 + 4 + 25
d² = 93
√d² = √93
d = 9.6
The equation should be: Rent = 80 + 0.75 * Miles, then the graph looks like:
Vertex: (5,0)
Focus: (5,1/4)
Axis of symmetry: x=5
Directrix: y= -1/4
D, it increases then goes at a constant speed
