Answer:
B) 420
Step-by-step explanation:
V= lwh
l = 7
w = 5
h = 12
V = (7)(5)(12)
V = 420
Answer:

Step-by-step explanation:
Given the equation of parabola

This is the vertex form of the parabola equation. Hence, the vertex of the parabola is at point 
This parabole goes downwards in y-direction (the leading coefficient -5 is negative)
<u>The axis of symmetry</u> of parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.
Thus, the equation of the axis of symmetry is

Answer:
A
Step-by-step explanation:
I think the answer is B. Hope this helps!!
