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
EXPLANATION
The given expression is
We regroup the numerical parts to get;
Now let us simplify the negative numbers.
We now subtract 19 from 42 to get;
We can't simplify further
Hence the simplest form is:
Given:
The inequality is
To find:
The solution set for the given inequality.
Solution:
We have,
Divide both sides by 3.
It can be written as
Subtracting 4 from each side, we get
The solution set of the given inequality is (-5,-3).
Therefore, the correct option is A.
3/2 because you divide both by 2
Answer:
Step-by-step explanation:
B is correct: We Divide it (the coefficient b) by 2 and square the result.
