77julia77 [94]
From the given ratio, we can get the percentages of the money that Plan G and the arena gets.
              Plan G percentage = (2/(2 + 5)) x 100% = 28.57%
                  Arena percentage  = (5/(2 + 5)) x 100% = 71.43%
We then multiply the amount they get by the decimal equivalent of the percentage of the arena.
                      Amount for arena = (£14,000) x (0.7143) = £10,000.2

The function 2 ft t t ( ) 5 20 60    models the approximate height of an object t seconds after it is launched. How many sec
yaroslaw [1]

The function involves the initial speed of the object, and the height
from which it was launched, and whether it was launched upward
or downward.  As you can see, your post was corrupted and is
unreadable.  But when the object hits the ground, its height is zero. 
Set the function equal to zero, solve the quadratic equation that you
have, discard the negative solution, and the positive solution is your
answer.
