 find the vertex equation form, f(x) = a(x-h)2 + k, for a parabola that passes through the point (-6,9) and has (-5,8) as its vertex. what is the standard form of the equation?

a)the vertex form of the equation is f(x) = (x + 5)2 + 8. the standard form of the equation is f(x) = x2 + 10x + 33.
b)the vertex form of the equation is f(x) = (x - 5)2 + 8. the standard form of the equation is f(x) = x2 - 10x + 33.
c)the vertex form of the equation is f(x) = −(x + 5)2 + 8. the standard form of the equation is f(x) = x2 - 10x + 33.
d)the vertex form of the equation is f(x) = (x + 5)2 - 8. the standard form of the equation is f(x) = −x2 + 10x - 33.

Nthe opening scene of the movie raiders of the lost ark, indiana jones replaces a golden statue with a bag of sand. the platform on which the statue is placed is designed to detect the mass of the statue. if the bag of sand has a different mass than the statue, then a mechanism triggers and destruction ensues. the density of gold is about 20\text{ g/cm}^320 g/cm 3 20, space, g, slash, c, m, start superscript, 3, end superscript. the density of sand can be estimated at 2.5\text{ g/cm}^32.5 g/cm 3 2, point, 5, space, g, slash, c, m, start superscript, 3, end superscript. the gold statue can be modeled as a cylinder with height 25\text{ cm}25 cm25, space, c, m and radius 8\text{ cm}8 cm8, space, c, m. in terms of \piπpi, what is the mass of sand indiana jones needs to avoid triggering the mechanism?
