Aball is thrown leftward from the left edge of the roof, at height h above the ground. the ball hits the ground 1.50 s later, at distance from the building and at angle with the horizontal. (a) find h. (hint: one way is to reverse the motion, as if on video.) what are the (b) magnitude and (c) angle relative to the horizontal of the velocity at which the ball is thrown? (d) is the angle above or below the horizontal?

The number of members f(x) in a local swimming club increased by 30% every year over a period of x years. the function below shows the relationship between f(x) and x: f(x) = 10(1.3)xwhich of the following graphs best represents the function? graph of f of x equals 1.3 multiplied by 10 to the power of x graph of exponential function going up from left to right in quadrant 1 through the point 0, 0 and continuing towards infinity graph of f of x equals 10 multiplied by 1.3 to the power of x graph of f of x equals 1.3 to the power of x
