Which statement is true about the given function? F(x) > 0 over the interval (–infinity, 3). F(x) > 0 over the interval (–infinity, infinity). F(x) < 0 over the interval (–infinity, 3). F(x) < 0 over the interval (–infinity, infinity)

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
