Find the second derivative of y with respect to x from the parametric equations given. 4) x=√1-t₁y = t³ - 3t 5) x 1 1/t, y = 6-7/t + 2/t² -arrow_forwardThe parametric equations x = x1 + (x2 – x1)t, y = Y1 + (Y2 - Yq)t where 0 sts 1 describe the line segment that joins the points P,(x,, Y,) and P,(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 comm separated list of equations. Let x and y be in terms of t.)

- Letter b. topic: derivative of parametric equationsarrow_forwardA wheel with radius 2 cm is being pushed up a ramp at a rate of 7 cm per second. The ramp is 790 cm long, and 250 cm tall at the end. A point P is marked on the circle as shown (picture is not to scale). P 790 cm 250 cm Write parametric equations for the position of the point P as a function of t, time in seconds after the ball starts rolling up the ramp. Both x and y are measured in centimeters. I = y = You will have a radical expression for part of the horizontal component. It's best to use the exact radical expression even though the answer that WAMAP shows will have a decimal approximation.arrow_forward
