Alright well for (A) you will round $5280 to $5300. Then you multiply $5300 by 28.
For (B) you just round up. So again $5280 rounds up to $5300.
Answer:
vertex: (1, -49)
x-intercepts: (-6, 0) and (8, 0)
Step-by-step explanation:
I graphed it and looked for the needed information
here's the graph if you want it:
Given:
The quadratic equation is

To find:
The x-intercepts of the given equation.
Solution:
We have,

Splitting the middle term, we get



For x-intercepts, y=0.

Using zero product property, we get




So, the x-intercepts are (0.5,0) and (2,0).
Therefore, the correct option is a.
