For some positive integers t, y + 5 = (1/t) * (x^2) intersects
x^2 + y^2 = 25 at exactly 3 points P, Q, and R (distinct from one
another). Determine the positive integers t for which the area of
triangle PQR is an integer.

And
Both r1(t) = < t2,
t4 > and r2(t)

Explain why the difference is logical and quantify the
difference at t=1.

Problem 1. The function h = f(t) = 90 − 5(t − 2)2 , 0 ≤ t ≤ 6,
gives the height of a rock (in meters) at time t seconds after
being launched straight up from the edge of a cliff. (a) Sketch an
accurate graph of the function h = f(t). Label the axes with the
appropriate variable names and units. Label the curve with its
equation. (b) Find a function g that expresses the time t when...
