Answer:
None
Step-by-step explanation:
The discriminant of a quadratic equation is . In this case, that is:
Since the discriminant is negative, the square root will be a complex number, and this equation must have no real solutions. Hope this helps!

Answer:
f(x) → -∞ as x → -∞
f(x) → -∞ as x → +∞
Step-by-step explanation:
The given function is;
f(x) = -5x^(6) + 8x^(5) - 1/(x² - 9x)
Using long division to divide this as attached, we have;
f(x) = -5x⁴ - 37x³ - 333x² - 2997x - 26973 + (-242757x - 1)/(x² - 9x)
Thus, the leading coefficient here is -5 and the polynomial degree is 4.
Since the leading coefficient is negative and the degree of the polynomial is an even number, then we can say that the behavior of the polynomial is;
f(x) → -∞ as x → -∞
f(x) → -∞ as x → +∞
Answer:
Selena went to a fruit market with some money in order to buy apples and bananas. She finds out that cost of each banana and each apple is cents. She has 2 cents less than the total amount for which she could buy 8 apples and 4 bananas. Write an expression that represents the total amount Selena had.
Step-by-step explanation:
Given expression:
To write a story that represents the given expression and find the equivalent expression.
Solution:
Selena went to a fruit market with some money in order to buy apples and bananas. She finds out that cost of each banana and each apple is cents. She has 2 cents less than the total amount for which she could buy 8 apples and 4 bananas. Write an expression that represents the total amount Selena had.
If 1 apple cost = cents
Then 8 apples will cost = cents
If 1 banana cost = cents
Then 4 bananas will cost = cents
Total cost of 8 apple and 4 bananas = cents
Selena has 2 cents less.
Amount Selena has = cents
The expression can be simplified by adding the like terms.

Answer:
A win or loss of the the team at the home location cannot be interpreted from the correlation coefficient.
Step-by-step explanation:
The correlation coefficient between two categorical variables is a numerical measure of the strength and direction of the relationship between them.
It is denoted by <em>r</em>. The value of <em>r</em> ranges from -1.00 to 1.00.
A correlation of 1.00 indicates a strong positive relationship between the variables. It also indicates a positive slope for the regression line, i.e. as the value of one variables increases the value of other also increases.
A correlation of -1.00 indicates a strong negative relationship between the variables. It also indicates a negative slope for the regression line, i.e. as the value of one variables increases the value of other decreases.
The correlation coefficient does not imply causation, i.e. it does implies that a change in one variable is because of the other variables just so they are correlated.
A change in the variables can be due to many other factors.
In this case the correlation coefficient between location of game and number of wins is computed as -0.91.
The correlation coefficient implies a negative relation between the variable.
But it does not implies that the number of wins of the team is affected by the location of the game.
So a win or loss of the the team at the home location cannot be interpreted from the correlation coefficient.
