Answer:
The axis of symmetry is
Step-by-step explanation:
we know that
In a vertical parabola, the axis of symmetry is equal to the x-coordinate of the vertex
In this problem we have a vertical parabola open upward
The x-coordinate of the vertex is equal to the midpoint between the zeros of the parabola
so
therefore
The axis of symmetry is
Sorry about that, here's the answers.
1. expanded form
2. regroup
3. place value
4. A, C, D. The strategy I used was place value and regrouping. I chose these by using place value to help me understand how to regroup and what each option would sum to.

Answer:
2008
Step-by-step explanation:
M = 48.81t + 304.30
M = 694.78 Solve for t
694.78 = 48.81t + 304.30 Subtract 304.30 from each side
390.48 = 48.81t Divide each side by 48.81
t = 390.48/48.81
t = 8.00 yr
=====
Year = 2000 + t
Year = 2000 + 8.00
Year = 2008
Military spending hit $694.78 billion at the end of 2008.
