What is a saddle point?In mathematics, a saddle point or minimax point is a point on the surface of the graph of a function where the slopes (derivatives) in orthogonal directions are all zero (a critical point), but which is not a local extremum of the function.
We have the following function -
F(x, y) = x³ + y³ - 3x² - 6y² - 9x
We will plot the 3 dimensional graph of this function. From the model it can be seen that, the local maximum value is 5 and the local minimum value is -3. Since the graph is discontinuous, we cannot locate the saddle points.
Therefore, for the function F(x, y) = x³ + y³ - 3x² - 6y² - 9x , the local maximum value is 5 and the local minimum value is -3. The graph is discontinuous, so we cannot locate the saddle points.

2. The angle theta is in standard position with a terminal arm in quadrant IV. If sin 0 =-1/5, find the values of the remaining five
trigonometric ratios for theta
AS per the concept of trigonometric ratios for theta, the value of cos θ = 2√6/5 , tan θ = -1/2√6 , cosec θ = -5, sec θ = 5/2√6 and the value of cot θ = -2√6.
Trigonometric ratio:
In math, there are six trigonometric ratios they are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).
Given,
The angle theta is in standard position with a terminal arm in quadrant IV. If sin θ =-1/5.
Now, we have to find the remaining five trigonometric ratio of the θ.
As we know that,
sin²θ + cos²θ = 1
Here we know that value of sin θ = -1/5, then the value of cos θ is calculated as,
=> (-1/5)² + cos² θ = 1
=> 1/25 + cos² θ = 1
=> cos² θ = 1 - 1/25
=> cosθ = √24/25
=> cos θ = 2√6/5
So, the value of tan θ = -1/2√6
Then the value of cosec θ = -5, sec θ = 5/2√6 and the value of cot θ = -2√6.

Lines 5(x+3) and y=5x+1 both are parallel.
What are parallel lines?
Parallel lines in geometry are coplanar, straight lines that don't cross at any point. In the same three-dimensional space, parallel planes are any planes that never cross. Curves with a predetermined minimum distance between them and no contact or intersection are said to be parallel.
Here, we have
Given equations = 5(x+3) and y=5x+1
Now we write both equations in standard form and we get
y = 5x + 3,
y = 5x + 1
Then, we compare the slopes of both equations and we get
Slope = 5
Hence, the slope of both equations is the same. so, the given lines are parallel.

Jim needs a score of 115 on his third test to keep an average of 89 or greater.
A mean represents the average value among a set of values.
Mean = (sum of all values)/(total number of values)
In other words, mean is the value assigned to each member of set after fair distribution. It means that if a set of n values has a mean of x, we can assume the set to be 'x' value recurring n times over the sample.
In this case, we have 3 test results: 83, 69 & x, where x is the unknown result of 3rd test. Our required minimum average/mean is 89.
Substituting these in our formula for mean, we get:
[tex]89=\frac{83+69+x}{3} \\89*3=152+x\\x=267-152=115[/tex]
Thus, 115 is our required test result for maintaining average of minimum 89.

The direct distance from home plate to the second base is 127.27 feet .
In the question ,
it is given that
the shape of base ball diamond = square ,
distance of one side = 90 feet ,
so , the distance of other side will be = 90 feet , because it is a square ,
the distance from home plate to the second base is represented by the diagonal ,
2 sides with length 90 feet and one diagonal forms a right angled triangle.
let the distance from home plate to the second base be " x" .
So , By Pythagoras Theorem ,
90² + 90² = x²
x² = 8100 + 8100
x² = 16200
x = √16200
x = 127.27

budgets $55 for each week. For how many weeks can she withdraw $55 from her savings account until the balance reaches $0?
Nicoletta can withdraw $55 from her savings account for 24 weeks until the balance reaches $0 .
Nicoletta sells jewelry during summer vacation .
From the table we can gather the following information:
Expenses = $ 26
Revenue = $132
Profit = $(132-26) = $ 106
Now she sells for 10 weeks.
profit each week = $ 106
Total profit over 10 weeks = $ 106 × 10 = $ 1060
Money deposited in the account after 10 weeks = $ 1060
Money originally in the account = $260
Total amount of money in savings account
= $ 1060 + $260
= $ 1320
She withdraws 55 each week.
Number of weeks it will sustain at that rate = 1320 / 55 =24

The t-score of 2.779 is used to find the 99% confidence interval for the population mean.
Given,
Assume that orangutans' heights, measured in inches, are regularly distributed with an unidentified mean and standard deviation. The population means are calculated using the orangutan heights of 27 orangutans that were randomly selected.
What t-score should be applied to determine the population mean's 99% confidence interval?
n = 27
confidence level = 0.99
We have to find a critical value for the confidence level of 0.99.
To find the critical value we need degrees of freedom and significance level.
df = n-1 = 27 - 1 = 26

Given,
A fish tank in a pet store has 21 fish in it. 9 are orange and 12 are white. determine the probability that if we select 4 fish from the tank, at least 2 will be white;
The probability that the fish is white = 12/21

For part A, first of all, you need to multiply both sides by 2.
4x - 1 = 2x + 14
Then, you need to add 2 to both sides.
4x = 2x + 15
Now, you need to subtract 2x from both sides.
2x = 15
Finally, you need to divide both sides by 2.
x = 7.5
So the answer to part A is 7.5
Now for part B.
First of all, you need to multiply both sides by 3.
9x + 6 = 2x + 13
Next, you need to subtract 6 from both sides.
9x = 2x + 7
Now, you need to subtract 2x from both sides.
7x = 7
Finally, you need to divide both sides by 7.
x = 1
