# Mathematics Use of Formulae

1. In a basketball playground, the region that is 4 m or more from the

basket is called the 3-point region. Ben is a good shooter and if his

distance from the basket in the 3-point region is d m, his rate of score (G) can be calculated by using the following formula:

G = 〔320/[(d-2)^2]%

(a) Find the scoring rate of Ben in position A:

(b) Find the scoring rate of Ben at the centre of the playground.

*5該列埋步驟!(只係要你計(b),唔使計(a))

同埋我唔係好知條題目要我做咩,幫我將條題目翻釋為中文!THX~!
