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:

Answer:
The correct solution is C (x> -2)
Actual length of the room
6 * 40
240 inches
Actual width of the room
4 * 40
160 inches
Area of the room
240 * 160
38400 inches^2

Answer:

Step-by-step explanation:
It is given that, the radius of a circle is 8 inches and we are to find the circumference of the circle.

To find the circumference of the circle we must know this formula first :

Where
- r is the radius of the circle.
- We'll take the value of π as 3.14
Now substituting the values in the formula :



Therefore,
- The circumference of the circle is 50.24 inches
Ok, if you decrease <span>£2500 by 1% you get 99% remaining
</span>So
99% of £2500 = 0.99 x £2500 = <span>£2475</span>
