Answer:

Student 2 used the correct steps to construct parallelogram PQRS.

Step-by-step explanation:

Out of all the students, student 2 got all the steps correct.

Fix the compass at Q and draw an arc that intersects side QP.

Without changing the width of the compass, move the compass to R and draw an arc.

Draw a line segment from R that passes through T and intersects the second arc at S.

Answer:

c) parabola and circle: 0, 1, 2, 3, 4 times

d) parabola and hyperbola: 1, 2, 3 times

Step-by-step explanation:

c. A parabola can miss a circle, be tangent to it in 1 or 2 places, intersect it 2 places and be tangent at a 3rd, or intersect in 4 places.

d. A parabola must intersect a hyperbola in at least one place, but cannot intersect in more than 3 places. If the parabola is tangent to the hyperbola, the number of intersections will be 2.

If the parabola or the hyperbola are "off-axis", then the number of intersections may be 0 or 4 as well. Those cases seem to be excluded in this problem statement.
