The parametric equations x = x1 + (x2 - x1)t, y = y1 + (y2 - y1)t where 0 ≤ t ≤ 1 describe the line segment that joins the points P1(x1, y1) and P2(x2, y2). Use a graphing device to draw the triangle with vertices A(1, 1), B(5, 3), C(1, 6). Find the parametrization, including endpoints, and sketch to check. (Enter your answers as a comma-separated list of equations. Let x and y be in terms of t.) A to B B to C A to C

Fill in the blanks to model the problem: The altitude (i.e. height) of a triangle is increasing at a rate of 3 cm/minute while the area of the triangle is increasing at a rate of 4.5 cm²/minute. At what rate is the base of the triangle changing when the altitude is 7 cm and the area is 84 cm²? Let h(t) and b(t) represent the length of the altitude and base of the triangle at time t minutes. What rate(s) of change do we want to find: What rate(s) of change do we know: What is the relationship between h, b, and A: In order to find, the next step is to both sides of the equation with respect to
