(Question 24)
In the plane rectangular coordinate system xOy, the analytical formula of parabola is y =+1,
The coordinates of point C are (–4,0), and vertices A and B of parallelogram OABC are parabolas.
On a straight line, the AB and Y axes intersect at point M, and point Q(x, y) is known to be on a parabola, while point
P(t, 0) is on the x axis.
(1) Write the coordinates of point m;
(2) When the quadrilateral CMQP is a trapezoid with MQ and PC as the waist.
① Find the resolution function of T about X and the range of independent variable X;
② When the ratio of the lengths of the two base sides of the trapezoid CMQP is 1: 2, find the value of t. 。
Is that a problem?
