Which of the following statements are always true? 1.
For a parabola written in standard form (
y=ax2+bx+c), if a > 0, the vertex represents the
absolute minimum point on the parabola.
II. Every parabola has one or more real zeros.
III. For a parabola with two real zeros, you can find the
coordinates of the vertex by finding the midpoint
between the roots, and evaluating the function at this x-
value.

one peck is 9.309 quarts

9.309x 2

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
