Answer:
2.58, 2.6, 2 5/8, 2 2/3
Step-by-step explanation:
2.58, 2.6, 2 5/8 can be converted into 2.625, and 2 2/3 can be converted into 2.66 with 6 being repeated over & over.
The axis of symmetry is at x = -3.
This can be found by looking at the basic form of vertex form:
y = (x - h)^2 + k
In this basic form the vertex is (h, k). By looking at what is plugged into the equation, it is clear that h = -3 and k = -4. This means the vertex is at (-3, -4).
It is a fact that the axis of symmetry is a vertical line of x = (vertex value of x). So we can determine that the axis of symmetry is at x = -3
You do mass divided by density
