Match the parametric equations with the graphs labeled I-VI. Give reasons for your choices. (Do not use a graphing device.)
(a) x = t4 − t + 1 . y = t2
(b)
(c) x = sin 2t, y = sin(t + sin 2t)
(d) x = cos 5t, y = sin 2t
(e) x = t +sin 4t, y = t2 + cos 3t
(f)

- Find a pair of parametric equations for y= 3(2-5)² +2. Show all your work for full credit.arrow_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_forwardThe path of a projectile that is launched h feet above the ground with an initial velocity of v0 feet per second and at an angle θ with the horizontal is given by the parametric equations x = (v0 cos θ)t and y = h + (v0 sin θ)t - 16t2,where t is the time, in seconds, after the projectile was launched.A football player throws a football with an initial velocity of100 feet per second at an angle of 40° to the horizontal.

The ball leaves his bat traveling with an initial speed of 120 ft/sec at an angle of 45° from the horizontal. Choose a coordinate system with the origin at ground level directly under the point where the ball is struck. Write parametric equations that model the path of the ball as a function of time t (in sec). When is the ball at its maximum height? Give the exact value and round to the nearest hundredth of a second. What is the maximum height? If an outfielder catches the ball at a height of 6 ft, for how long was the ball in the air after being struck? Give the exact answer and the answer rounded to the nearest hundredth of a second. How far is the outfielder from home plate when he catches the ball? Round to the nearest foot.arrow_forward
