5 The height of a ball t seconds after it is thrown is modelled by the function h(t) = -4.982 +240 +2, where h is the height of the ball in metres.
a Write down the initial height of the ball.
b Find the maximum height of the ball.
c Find the length of time the ball is at least 18 metres high,
d Find the amount of time elapsed when the ball hits the ground.

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y < 4x − 8 y is greater than or equal to negative 5 over 2 times x plus 5 part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points) part b: is the point (5, −8) included in the solution area for the system? justify your answer mathematically. (4 points)
