The quiz will close when the period ends. This quiz is worth 20 marks so should be completed in 20 minutes. Extra time has been given to account for the fact that it may take longer to show work online. If you have been completing your assignments and have studied, 20 minutes should be enough time. A desmos calculator has been provided below if you need it. I also put a screen shot of some information from the formula booklet that you might need.
