What is matrix?A rectangular array of characters, numbers, or phrases arranged in rows and columns is known as a matrix.
Given matrix, where we have to find out, is the game strictly determined for the following matrix or not?
[tex]\left[\begin{array}{ccc}-7&7&-3\\3&8&6\\1&3&-3\end{array}\right][/tex]
Using the minimax theorem, we know that if the game is strictly determined, the value of the game is equal to the value of the saddle point. If the game is not strictly determined, the value of the game may not exist or may be a range of values.
We can check each row and column for minimum and maximum values:
The minimum value in the first row is -7.
The maximum value in the second column is 7.
The minimum value in the third row is -3.
We can see that the element in the first row and second column is both the minimum in its row (-7) and the maximum in its column (7), so it is a saddle point. Therefore, the game is strictly determined and the value of the game is -7.
The answer is A. The game is strictly determined and the value of the game is -7.

The suspension cable that supports a footbridge hangs in the shape of a parabola. The height h, in feet, of the cable above the bridge is given by the function
h(x) = 0.25x ^ 2 - 0.8x + 30, 0 < x < 3.2
where x is the distance in feet measured from the left tower toward the right tower. What is the minimum height of the cable above the bridge? (Round your answer to two decimal places.)
Answers
Step-by-step explanation:
The height of the cable above the bridge is given by the function:
h(x) = 0.25x^2 - 0.8x + 30
To find the minimum height of the cable above the bridge, we need to find the vertex of the parabola, which is the lowest point.
The x-coordinate of the vertex is given by:
x = -b / 2a
where a = 0.25 and b = -0.8. Substituting these values, we get:
x = -(-0.8) / 2(0.25) = 1.6
So the vertex is at x = 1.6.
To find the height of the cable at the vertex, we substitute x = 1.6 into the equation for h(x):
h(1.6) = 0.25(1.6)^2 - 0.8(1.6) + 30 = 29.48
Therefore, the minimum height of the cable above the bridge is approximately 29.48 feet (rounded to two decimal places).

Let y = f(x). Then we have:
y = 3/(7x + 1)
Multiplying both sides by 7x + 1, we get:
y(7x + 1) = 3
Expanding the left side, we get:
7xy + y = 3
Subtracting y from both sides, we get:
7xy = 3 - y
Dividing both sides by 7y, we get:
x = (3 - y)/(7y)
Therefore, the inverse of f(x) is:
f^-1(x) = (3 - x)/(7x)
Explanation: To find the inverse function, we set y = f(x) and solve for x. By isolating x on one side of the equation in terms of y, we obtain the inverse function.
B. Let g(x) = (3 - x)/(7x). We need to verify that (f(g(x))) = x for all values of x in the domain of f(x) and g(x).
We have:
f(g(x)) = f((3 - x)/(7x)) = 3/(7((3 - x)/(7x)) + 1) = 3/(3 - x + 7x)/(7x) = 3/(3 + 6x)/(7x) = (21x)/(3 + 6x) = 7x/(1 + 2x)
To show that (f(g(x))) = x, we need to show that:
7x/(1 + 2x) = x
Multiplying both sides by (1 + 2x), we get:
7x = x(1 + 2x)
Expanding the right side, we get:
7x = x + 2x^2
Subtracting 7x from both sides, we get:
0 = x + 2x^2 - 7x
Simplifying, we get:
2x^2 - 6x = 0
Dividing both sides by 2x, we get:
x - 3 = 0
Therefore, x = 3.
Since we have shown that (f(g(x))) = x for x = 3 (which is in the domain of both f(x) and g(x)), we can conclude that g(x) is the inverse of f(x).
C. We cannot answer part C of the question because no function is given. The table provided only shows a set of input-output pairs, but we need the function itself to perform any further analysis.
The domain and range of the inverse function f^-1(x) = (3 - x)/(7x) depend on the domain and range of the original function f(x) = 3/(7x + 1).
The domain of f(x) is all real numbers except -1/7 (since division by zero is undefined). Therefore, the range of f^-1(x) is all real numbers except 0, since division by zero is also undefined.
To find the domain of f^-1(x), we can consider the denominator of the expression for f^-1(x), which is 7x. Since division by zero is undefined, we need to exclude any value of x that makes the denominator equal to zero. Therefore, the domain of f^-1(x) is all real numbers except 0.
In summary:
Domain of f^-1(x): All real numbers except 0
Range of f^-1(x): All real numbers except 0
Find a quadratic function that includes the set of values below.
(0,7), (2,17), (3,16)
The equation of the parabola is Y
Answers
Y = aX^2 + bX + c
where Y is the output (dependent variable), X is the input (independent variable), and a, b, and c are constants that we need to solve for.
We can plug in the three sets of values given into this equation to get three equations:
7 = a(0)^2 + b(0) + c
17 = a(2)^2 + b(2) + c
16 = a(3)^2 + b(3) + c
Simplifying each equation, we get:
7 = c
17 = 4a + 2b + c
16 = 9a + 3b + c
Substituting c = 7 from the first equation into the other two equations, we get:
17 = 4a + 2b + 7
16 = 9a + 3b + 7
Simplifying these equations, we get:
4a + 2b = 10
9a + 3b = 9
We can solve this system of equations using substitution or elimination to find the values of a and b. I'll use elimination:
Multiplying the first equation by 3 and the second equation by -2, we get:
12a + 6b = 30
-18a - 6b = -18
Adding the two equations, we get:
-6a = 12
a = -2
Substituting a = -2 into one of the equations we got earlier (e.g. 4a + 2b = 10), we get:
4(-2) + 2b = 10
-8 + 2b = 10
2b = 18
b = 9
So the values of a and b are -2 and 9, respectively. Substituting these values into the general form of the quadratic function, we get:
Y = -2X^2 + 9X + 7
Therefore, the equation of the parabola is:
Y = -2X^2 + 9X + 7

Answers
C = 2πr = 2π(70) ≈ 439.82 m
Since the corner is a quarter of a cube, its length is equal to one-fourth of the cube's edge length, which is:
l = (1/4) x 22 = 5.5 m
The distance Ali walks from A to B is equal to the length of the inside of the corner, which is approximately 439.82 m.
To find the distance Obi walks from C to D, we need to calculate the length of the path around the outside of the corner. The outside radius of the corner is equal to the sum of the inside radius and the width of the road, which is:
r' = r + w = 70 + 7 = 77 m
The length of the path around the outside of the corner is:
L = 2πr' = 2π(77) ≈ 483.43 m
Since Obi walks around the outside of the corner, he walks a distance that is greater than the distance Ali walks on the inside. Therefore, Obi walks:
483.43 m - 439.82 m = 43.61 m

What precisely is a triangle?A triangle is a closed, double-symmetrical shape composed of three line segments known as sides that intersect at three places known as vertices. Triangles are distinguished by their sides and angles. Triangles can be equilateral (all factions equal), isosceles, or scalene based on their sides. Triangles are classified as acute (all angles are fewer than 90 degrees), good (one angle is equal to 90 degrees), or orbicular (all angles are higher than 90 degrees) (all angles greater than 90 degrees). The region of a triangle can be calculated using the formula A = (1/2)bh, where an is the neighbourhood, b is the triangle's base, and h is the triangle's height.

) Using matrix method solve the following simultaneous equations 1x + 4y = 9 2x – 3y = 7
Answers
Answer: To solve the system of equations using the matrix method, we first need to set up the corresponding coefficient matrix and augmented matrix:
Coefficient matrix:
[1 4]
[2 -3]
Augmented matrix:
[1 4 | 9]
[2 -3 | 7]
To solve the system using matrix method, we perform row operations on the augmented matrix to get it into row echelon form, and then back substitute to obtain the solutions.
Performing row operations:
Multiply the first row by 2 and subtract the result from the second row:
[1 4 | 9]
[0 -11| -11]
Divide the second row by -11:
[1 4 | 9]
[0 1 | 1]
Subtract 4 times the second row from the first row:
[1 0 | 5]
[0 1 | 1]
The row echelon form of the augmented matrix is:
[1 0 | 5]
[0 1 | 1]
Therefore, the solution is x = 5 and y = 1.
So the solution of the system of equations is x = 5 and y = 1.

Answers
To divide 240g in the ratio 5:3:4, we need to find out the total number of parts of the ratio:
5 + 3 + 4 = 12
Now, we can find the value of one part of the ratio by dividing the total quantity by the total number of parts:
240g ÷ 12 = 20g
So, one part of the ratio is equal to 20g.
To find the quantities of each part of the ratio, we multiply the value of one part by the respective ratio number:
5 parts x 20g = 100g (for the first part)
3 parts x 20g = 60g (for the second part)
4 parts x 20g = 80g (for the third part)
Therefore, the quantities of 240g divided in the ratio 5:3:4 are 100g, 60g, and 80g respectively.

If cos 55° = p determine the value of cos 5° in terms of p.
Answers
Answer:
Step-by-step explanation:
We can use the identity for the cosine of the sum of two angles:
cos(a + b) = cos(a)cos(b) - sin(a)sin(b)
In this case, we can write:
cos(60°) = cos(55° + 5°) = cos(55°)cos(5°) - sin(55°)sin(5°)
We know that cos(60°) = 1/2, and we also know that cos(55°) = p. We can solve for cos(5°):
1/2 = p cos(5°) - sin(55°)sin(5°)
sin(55°)sin(5°) = p cos(5°) - 1/2
We also know that sin²(55°) + cos²(55°) = 1, so:
sin²(55°) = 1 - cos²(55°) = 1 - p²
Substituting this into the previous equation:
(1 - p²)sin(5°)² = p cos(5°) - 1/2
Rearranging and factoring:
p cos(5°) = 1/2 - (1 - p²)sin(5°)²
Using the fact that sin²(5°) + cos²(5°) = 1, we can substitute cos²(5°) = 1 - sin²(5°):
p cos(5°) = 1/2 - (1 - p²)(1 - cos²(5°))
Simplifying:
p cos(5°) = 1/2 - (1 - p²) + (1 - p²)cos²(5°)
p cos(5°) = 1 - 2p² + (2p² - 1)cos²(5°)
Solving for cos²(5°):
cos²(5°) = (1 - p cos(5°) + 2p²) / (2p² - 1)
Substituting the value we found for p, cos²(55°) = p²:
cos²(5°) = (1 - p cos(5°) + 2cos²(55°)) / (2cos²(55°) - 1)
Finally, substituting p = cos(55°):
cos²(5°) = (1 - cos²(55°) cos(5°) + 2cos²(55°)) / (2cos²(55°) - 1)
cos²(5°) = (2cos²(55°) - cos²(55°) cos(5°) + 1) / (2cos²(55°) - 1)
cos²(5°) = (cos²(55°) + 1) / (2cos²(55°) - 1)
Therefore, the value of cos 5° in terms of p = cos 55° is:
cos 5° = ±sqrt[(cos²(55°) + 1) / (2cos²(55°) - 1)]
Note that the sign of the square root is determined by the quadrant in which 5° lies. Since 5° is in the first quadrant, cos 5° is positive.

Case 5: s = 116π / 9 yd, A = 928π / 9 yd²
Case 6: s = 13π / 12 ft, A = 13π / 8 ft²
How to determine the arc length and the area of a circle sector
In this problem we need to determine the arc length (s), in yards or inches, and the area (A), in square yards or square inches, of a circle sector, whose formulas are listed below:
Arc length
s = (θ / 180) · π · r
Area
A = 0.5 · (θ / 180) · π · r²
Where:
θ - Measure of the central angle, in degrees. r - Radius, in yards or inches.Now we proceed to determine the arc length and the area for each case:
Case 1 (r = 11 yd, θ = 165°)
s = (165 / 180) · π · 11
s = 121π / 12 yd
A = 0.5 · (165 / 180) · π · 11²
A = 1331π / 24 yd²
Case 2 (r = 14 in, θ = 150°)
s = (150 / 180) · π · 14
s = 35π / 3 in
A = 0.5 · (150 / 180) · π · 14²
A = 245π / 3 in²
Case 3 (r = 3 ft, θ = 170°)

Your firm purchases large shipments of a component, subject to the requirement that not more than 4% of a shipment may be defective. If a random sample of 200 parts from a new shipment reveals 12 defectives, can you reject this shipment as not meeting requirements, at the 5% level of significance?
Answers
Answer:
see the attachment
Step-by-step explanation:
Since the p-value is greater than the significance level of 0.05, we fail to reject the null hypothesis. Therefore, we do not have sufficient evidence to conclude that the shipment does not meet requirements.
Which of the loans should you try to pay off first?
A. a loan for $3,400 at 16%
B. a loan for $3,500 at 15%
C. a loan for $3,600 at 14%
D. a loan for $3,700 at 13%
Answers
A loan for $3,400 at 16% should be paid first as it has the highest interest rate.
What is loan?A loan is a financial agreement in which one party (the lender) agrees to give money, property, or other assets to another party (the borrower) in exchange for the promise of repayment with interest or other charges. Loans are typically used by individuals, businesses, or governments to finance specific projects, make purchases, or cover expenses.
Assuming that all other factors such as minimum payments and penalties are the same, the loan that you should try to pay off first is the one with the highest interest rate, as it will be accruing interest at a faster rate than the others.
Based on this reasoning, the loan that you should try to pay off first is option A, which has a higher interest rate of 16%.

Find the length of side � x in simplest radical form with a rational denominator. 30° 60° x 2
Answers
The length οf side x can be any value, as lοng as it is nοt 0.
We can use the trigοnοmetric ratiοs fοr 30°-60°-90° triangles tο sοlve fοr the value οf x.
In a 30°-60°-90° triangle, the sides are in the ratiο:
1 : √3 : 2
In this case, we have the side οppοsite the 60° angle (which is the lοnger leg) equal tο x√3 and the side οppοsite the 30° angle (which is the shοrter leg) equal tο x.
Sο we can set up the fοllοwing equatiοn:
x√3 = 2x sin 60°
Simplifying the right side:
sin 60° = √3/2
2x sin 60° = 2x(√3/2) = x√3
Substituting back intο the equatiοn:
x√3 = x√3
This is true fοr any value οf x, as lοng as x is nοt equal tο 0. Therefοre, the length οf side x can be any value, as lοng as it is nοt 0.

What referents would you use to estimate the length, in both SI units and imperial units, of the Victoria (Old Traffic) Bridge in Saskatoon? Explain how you could measure the length in both units.
Answers
Step-by-step explanation:
The Victoria (Old Traffic) Bridge in Saskatoon, Canada, has a length of approximately 230 meters (755 feet). To estimate the length of the bridge in both SI and imperial units, you can use the following referents:
SI Units:
To estimate the length of the bridge in SI units, you can use meters as the referent. The length of the Victoria Bridge can be measured using a distance measuring device such as a surveyor's wheel, a laser distance meter, or a tape measure. You can start at one end of the bridge and measure the distance to the other end. This will give you an accurate measurement of the length of the bridge in meters.
Imperial Units:
To estimate the length of the bridge in imperial units, you can use feet as the referent. You can use a tape measure or a distance measuring wheel that measures in feet. You can start at one end of the bridge and measure the distance to the other end. This will give you an accurate measurement of the length of the bridge in feet.
To convert the length from meters to feet or vice versa, you can use the following conversion factors:
1 meter = 3.28 feet
1 foot = 0.3048 meters
Therefore, to convert the length of the Victoria Bridge from meters to feet, you can multiply the length in meters by 3.28. For example, 230 meters x 3.28 = 754.4 feet (rounded to the nearest tenth).
To convert the length of the Victoria Bridge from feet to meters, you can multiply the length in feet by 0.3048. For example, 755 feet x 0.3048 = 230.1 meters (rounded to the nearest tenth).

The measure of angle ZUB is 32.8°.
What precisely is a triangle?A triangle is a closed, double-symmetrical object composed of three line segments known as sides that intersect at three points known as vertices. Triangles are distinguished by their sides and angles. Triangles can be equilateral (all factions equal), isosceles, or scalene based on their sides.
Triangles are classified as acute (all angles are less than 90 degrees), okay (one angle is equal to 90 degrees), or orbicular (all angles are greater than 90 degrees) (all angles greater than 90 degrees). The region of a triangle can be calculated using the formula A = (1/2)bh, where an is the neighborhood, b is the triangle's base, and h is the triangle's height.
Since the angles given are 90 degrees and 57.2 yοu can add thοse tοgether then subtract them frοm 180 tο find the answer.
180 - 90 + 57.2 = 32.8
Thus,
32.8° is the answer.

6.5 practice the measure of the exterior of a triangle is equal to the sum of the remote interior angles?
Answers
Answer:
Step-by-step explanation:
Yes, that is correct. The measure of the exterior angle of a triangle is equal to the sum of the two remote interior angles. In other words, if you extend one side of a triangle to form an exterior angle, then the measure of that exterior angle is equal to the sum of the measures of the two interior angles that are not adjacent to the exterior angle. This property is known as the Exterior Angle Theorem.
Mathematically, we can express this as:
Exterior angle = Sum of remote interior angles
Or, in symbols:
∠ABC = ∠A + ∠C
where ∠ABC is the exterior angle formed by extending side BC of triangle ABC, and ∠A and ∠C are the two remote interior angles.
Here are two more examples that illustrate the Exterior Angle Theorem:
Example 1:
Consider a triangle ABC with angles A, B, and C as shown below. If we extend side AC to form an exterior angle, then we can label the exterior angle as ∠DCE. The remote interior angles are ∠B and ∠A.
