The points P ( -5, 6),  Q ( -3, 8) and R(3, 2) are joined to form a triangle. a Show that angle PQR is a right angle.
b Find the equation of the circle that passes through the points P, Q and R

The data in the table represent the height of an object over time. which model best represents the data? height of an object time (seconds) height (feet) 05 1 50 2 70 3 48 quadratic, because the height of the object increases or decreases with a multiplicative rate of change quadratic, because the height increases and then decreases exponential, because the height of the object increases or decreases with a multiplicative rate of change exponential, because the height increases and then decreases
