b) Plot the points (x, y) from the table on the coordinate plane below. Indicate the direction of increasing t.
2. Convert the following parametric equations into Cartesian form (y = f(x)).
a) x(t) = t + 3, y(t) = 2t - 1
Cartesian Equation:
b) x(t) = 3cos(t), y(t) = 3sin(t)
Cartesian Equation:
3. Which of the following parametric equations represents a parabola opening upwards?
x(t) = t, y(t) = -t^2
x(t) = t^2, y(t) = t
x(t) = t, y(t) = t^2 + 1
x(t) = sin(t), y(t) = cos(t)
4. A projectile is launched with parametric equations x(t) = 20t and y(t) = 30t - 5t^2, where x and y are in meters and t is in seconds.
a) What is the horizontal distance traveled by the projectile after 3 seconds?
b) What is the height of the projectile after 3 seconds?
