Answer:

A non-square rhombus is not a rectangle.

Step-by-step explanation:

A parallelogram is a quadrilateral (four-sided figure) that has two pairs of parallel sides.

A rectangle is a parallelogram with four right angles.

If a parallelogram does not have four right angles, then it is not a rectangle.  However it is still a parallelogram, as it has two pairs of parallel sides.

The equation of a parabola is given.
Irina18 [472]

y = −1/4x^2 + 4x − 19

1. Use x = -b/2a to find x.

x = -4/2(-1/4)

x = -4/(-1/2)

x = -4/1 • (-2/1)

x = 8/1

x = 8

2. Plug x into the function to find your vertex.

Replace every x you see in the function with 8 and do the math.

Take it from here.
