Let the square ABCD be a parallelogram where the distance between the parallel lines AB and CD is 6. Let E and F be the centres of sides BC and CD. Line DE intersects line BF at point P and line AB at point Q. a) Show that | AQ | = 2 | AB | is truth.

b) Show that P lies on the line AC and determine the length of the distance from P to line AB.

Please, help me with this one

the answer is sugar ice cream pie

Step-by-step explanation:

the answer is sugar ice cream pie

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
