The easiest way to do this is the following: if the amount increases with 7% each year, it means that you have to multiply the £400 by 1,07. Then you multiply that answer by 1,07 and one time again. The final answer is 490,0172
Answer:
The function f(x) is represented by:

Hence, a=1500 and b=0.97
Step-by-step explanation:
The patient currently has a bone density of 1,500 kg/mg^3.
A doctor estimates that a particular patient is losing bone density at a rate of 3% annually.
This means that the bone density that is remaining is:
100-3=97%
which is also represented as: 97%=97/100=0.97
Hence, the function f(x) that represents the bone density after x years is represented by:

where a is the initial bone density which is given to be: 1500 kg/mg^3.
Hence, the function is:

Neither of them are correct. When you plug in both of the fractions into the equation, you get answers like 2/9 (from plugging in 1/3) and 1/9 (from plugging in 1/6). None of them are equal to 9.
The contestants total number of points is 20.
30 + 15 = 45
45 - 25 = 20 total points
