by unitary method the exact answer is correct (2,920 glasses).
given, glasses of water each day = 8
therefore, by unitary method :
glasses of water in 365 day =
hence the total glasses of water in 365 days = 2,920

Answer:
The coefficient of the squared expression in the parabola equation is
Step-by-step explanation:
The equation of a parabola in its vertex form is:
Where the vertex of the parabola is the point (h, k)
a is the ceoficiente of the term to the square.
We need to find the equation of a parabola that has its vertex in the point:
(-5, -2)
So:
Therefore the equation is:
We know that the point (-4, 2) belongs to this parable. Then we can find the value of a by replacing the point in the equation of the parabola
Finally the coefficient is a = 4
