Answer: Hello your question is incomplete attached below is the complete question.
answer:
a) The number of ferromagnetic artifacts per 100 square meters ( option A )
b) quantitative ( option D )
c) Entire Tara region ( option A )
Step-by-step explanation:
a) Determine The Variable
The number of ferromagnetic artifacts per 100 square meters
b) The Variable is quantitative
This is because the variable used in the study has numerical value attached to it hence we can say it is a quantitative variable.
c) The implied population
Entire Tara region
ANSWER
See explanation
EXPLANATION
The standard form of a quadratic equation is:

To convert this function to standard form, you follow the steps below:
- Factor 'a' from the variable terms
- Add and subtract the square of half the coefficient of x.
- Factor the perfect squares
- Simplify the constant terms to get the vertex form as

For example:
Given the standard form:

Factor 2 from the variable terms

Add and subtract the square of 3.


Factor the perfect square an simplify

This is the vertex form
0=0
it is n the range of 0≤x≤4
so
do x+3
0+3=3
it is 3
