No they are have a great day
To solve this we just need a polynomial where the roots can be -10 so in (x -/+ N)
The Ns must equal -10
We also know there must be at least a degree of 2 or higher, so we want X^3 or 3 roots. Given this we can construct our function;
H(x) = (X-2)(X+5)(X+1)
1*5*-2 = -10
So multiplying that out to get the standard form
X^2-2X+5X-10(X+1)
Simplifying to X^2 +3X-10(X+1)
X^3+3X^2-10X + X^2 +3X -10
Which simplifies to:
X^3+4X^2-7X-10
And below the desmos shows the y-int at (0,-10)
Answer:
The degree is 6, and the zero is 0
Step-by-step explanation:
Hope this helps! :) ~Zane
P.S. sorry if im wrong with the zero one
Answer:
C; B
Step-by-step explanation:
The direct/explicit formula for a geometric sequence is the following:
Where <em>aₙ </em>represents the term <em>n</em>, <em>a</em> represents the initial value, and <em>r</em> represents the common ratio.
Therefore, to find the <em>nth</em> term, we just need to find the initial value and the common ratio.
1)
-8, 24, -72, 216...
The common ratio is the ratio between each consecutive term. Do two to confirm that they are indeed the same. Thus:
So, the common ratio is -3. And the initial value is -8. Thus, putting them into our equation:
Thus, the eighth term will be:
C
2)
Again, find the common ratio.
2, -14, 98, -686...
The common ratio is -7. The initial value is 2. Thus:
And the sixth term will be:
B
Answer: A) Stratified random sampling
Step-by-step explanation:
Since , the researchers divided college students into the four classes (freshman, sophomore, junior, and senior) and then took a random sample of students from each class.
That means each category is participating in the sample.
It means , they used stratified sampling method where each class denotes a strata.
- <em>Stratified random sampling</em><em> is a kind of random sampling technique in which the researcher divides the whole population into some finite number of groups also known as strata , the he randomly pick individuals from each strata to make a sample. </em>
Here , each category participates in researcher's analysis.
Hence, the correct answer is A) Stratified random sampling .
