From the quadratic formula, the zeros (where y=0) is -b/(2a) +/- sqrt(b^2 -4ac)/(2a). The expression inside the square root is known as the descriminant. Being that the parabola is symmetric, one of the zeros will be at the vertex + sqrt(b^2 -4ac)/(2a) and the other zero is at vertex - sqrt(b^2 -4ac)/(2a). The vertex is halfway between these two values, so the x coordinate of the vertex is -b/(2a).
Or if you use Calculus, you can take the derivative of f(x) = ax^2 + bx + c.
f'(x) = 2ax + b. Set equal to zero and solve for x. x = -b/(2a).
yes . he had given it
A mathematical formula is a statement which, given all but one of a set of variables, allows you to calculate the possible value(s) of the missing variable. Many formulae will give single solutions but the quadratic formula, for example, usually has two solutions.
1/2*base*height = area Multipiy both sides by 2 and then divide both sides by the given value which then will give the value of the other side. Use Pythagoras' theorem to find the hypotenuse:- a2+b2 = c2
That would depend on its positional place value in any particular number of which none have been given.
Make the radius the subject of the formula 4/3*pi* radius3 = volume and then double it to give the diameter.

No
The vertex is the hightest point or each angular point of a geometrical figure. We stood at the vertex of the mountain.

The chemical formula is representative for a molecule and give indication about the chemical composition.

Infinitely many. Given any triangle, a line from a vertex to any point on the opposite side will give two triangles. That process can continue indefinitely.
It all depends on the current condition of the rifle. You have not given description so it is not possible to give an estimate of value
Im here to answer your question- possibly a cone. * * * * * and give you the wrong answer. A cone is a shape with 1 vertex: not MORE THAN 1 vertex! All polyhedra have more than 1 vertices.
if it has lost its sentimental value then it has lost its meaning
Newton's second law F=ma can be rearranged to give acceleration: a=F/m
