Factorising is when you put the equation in expandable brackets.
3x^2- 27 … you divide the whole thing by 3 to get x^2- 9 and that’s the furthest you can simplify
Answer:
The value of y is 16.
Step-by-step explanation:
You have to substitute x = 2 into the equation :

Let x = 2,




Answer:
1. k=0
2. yes, result is still a polynomial.
3. yes, f and g must have the same degree to have deg(f+g) < deg(f) or deg(g)
Step-by-step explanation:
1. for what constant k must f(k) always equal the constant term of f(x) for any polynomial f(x)
for k=0 any polynomial f(x) will reduce f(k) to the constant term.
2. If we multiply a polynomial by a constant, is the result a polynomial?
Yes, If we multiply a polynomial by a constant, the result is always a polynomial.
3. if deg(f+g) is less than both deg f and deg g, then must f and g have the same degree?
Yes.
If
deg(f+g) < deg(f) and
deg(f+g) < deg(g)
then it means that the two leading terms cancel out, which can happen only if f and g have the same degree.
The correlation coefficient measures the relationship between the two variables
The correlation coefficient is 0.234
<h3>How to determine the correlation coefficient</h3>
The formula of correlation coefficient is:

Using the dataset from the complete question, we have:

Evaluate the difference

Evaluate the quotient

Approximate

Hence, the correlation coefficient is 0.234
