Answer: 333.33m²
Step-by-step explanation:
Since we are informed that 15 litres of paint covers an area of 250 m2, the the area that 1 liter of paint will cover will be:
= 250m²/15
= 16.666667m²
Therefore, the area that 20 litres of paint will cover will be:
= 16.666667m² × 20
= 333.33m²

Answer:

Step-by-step explanation:
We have the quadratic function:

And we want to determine its axis of symmetry.
Notice that this is in vertex form:

Where (<em>h, k</em>) is the vertex of the parabola.
From our function, we can see that <em>h</em> = 4 and <em>k</em> = -2.5. Hence, our vertex is the point (4, -2.5).
The axis of symmetry is equivalent to the <em>x-</em>coordinate of the vertex.
The <em>x-</em>coordinate of the vertex is 4.
Therefore, the axis of symmetry is <em>x</em> = 4.
