because moon artefacts are prone to damage and need to be protected
Square root of 1/8 is irrational, so is square root of 1/2, so is square root of 1/10.
Answer:
(D)On a coordinate plane, a parabola opens up with x-intercepts at (negative 2, 0) and (2, 0), and a y-intercept at the vertex (0, negative 4).
Step-by-step explanation:
For a parabola
to have a minimum vertex, it must open upward. (a>0).
In the given options, the parabola which opens upward is option D.
On a coordinate plane, a parabola opens up with x-intercepts at (negative 2, 0) and (2, 0), and a y-intercept at the vertex (0, negative 4).
Therefore, it has a minimum vertex with coordinates (0,-4).
Answer:
2
Step-by-step explanation:
The line intersects at (0, -3) and (2, 1). Slope is m. 
Sub your values in. 
Your slope is 2.
