In this case, we have instead of, and instead of. Ī formula that your teacher may have wanted to make you memorize says that a quadratic function (b) is a quadratic function with the negative leading coefficient. Which is not in the domain where the model function should be defined,Īnd it would not make sense to say that the diver is in the air for a negative number of seconds after jumping off the board. The other choice,, yields a negative value for , Since the function was defined for a domain of , So we re-write the polynomial (and the equation) as We notice that can be factored many ways,īut one of them,, has factors that add to the middle coefficient: To solve that quadratic equation we could (a) The diver hits the water at, when the diver's height, (in feet), above the water is Times after the diver hits the water make no sense either. Negative times make no sense, because the model equation/function cannot predict how high above the water the diver was at various times before jumping off the board. Is the total time (in seconds) that the diver is in the air.

Where is the time since the diver jumped off the diving board, and The diver's height, (in feet), above the water can be modeled by “For now though, we must really focus on being in our best shape for the World Cup, European Championships and Olympic Games.You can put this solution on YOUR website! This will be especially important during the warm up sessions, and will be an extremely valuable experience for our divers. “It will also be very important to experience the venue in Japan, and how the organisers manage COVID protocols at what is usually an extremely busy event. Last year, I was so impressed with how hard our divers worked when they were out of the water and they came back in better shape than me and my coaches could have imagined. I am, however, very confident in our preparations. This is such a key competition for us, with qualification still up for grabs in certain events and having been out of competition for so long. “I’m delighted to name such a strong British team for the World Cup. Of the team named, British Diving’s Performance Director, Alexei Evangulov, said: The 2018 edition of this event saw City of Leeds star Laugher bag a brace of medals in the Men’s 3m and Men’s 3m Synchro – and he will be hoping for a similar level of success when he resumes competitive action for the first time in 14 months. Postponed from its original date of 21st-26th April 2020, the biennial FINA Diving World Cup, which typically doubles up as the test event in Olympic years, will now run from 18th-23rd April 2021. Meanwhile, the likes of Daley, Laugher and Grace Reid will all focus on the synchro events alongside their respective partners, given they have already secured qualification spots, with a view not only to top-level performances but also getting competition experience in the Olympic venue.

Whilst Great Britain has qualified a pair of spots in most disciplines, thanks to strong performances at the 2019 World Aquatics Championships in Gwangju, there are still single spots up for grabs in the Women’s 3m Springboard and 3m Synchro, as well as the Women’s 10m Platform and 10m Synchro events.īritish champion James Heatly and Rio 2016 medallist Dan Goodfellow will contest the Men’s 3m Springboard event, vying for the final Olympic berth in that discipline, whilst rising star and 2020 British champion Andrea Spendolini-Sirieix will line up in the Women’s 10m Platform event – as will European medallist Robyn Birch. Headlining the team are the usual marquee names of Tom Daley and Jack Laugher – but they are joined by a plethora of young talent looking to secure a return ticket to Tokyo for the Games themselves in four months’ time.

Taking place inside the Tokyo 2020 aquatics venue, the event will act as the perfect dress rehearsal for Britain’s diving talent, with a handful of Olympic qualification slots still up for grabs.
