The radius of a circle with centre O is 5 cm. The lengths of the chords AB and BC are 6 cm and 8 cm respectively. The midpoints of the chords are X and Y respectively. Find the perimeter of the quadrilateral OXBY. ​

The true statement based on the relationship depicted in the Venn diagram is that no rhombuses are trapezoids (option D).

To identify the true statement using the relationship represented in the Venn diagram, we need to analyze the overlapping regions and the properties of the shapes involved.

A trapezoid is a quadrilateral with at least one pair of parallel sides, while a rhombus is a quadrilateral with all sides of equal length. Let's evaluate the options:

A. All trapezoids are rhombuses: This statement is not true based on the diagram. The overlapping region between the trapezoids and rhombuses shows that there are trapezoids that are not rhombuses. Therefore, option A is incorrect.

B. All rhombuses are trapezoids: This statement is true based on the diagram. The entire region representing rhombuses is also included within the region representing trapezoids. Every rhombus can be considered a trapezoid because it has at least one pair of parallel sides. Thus, option B is correct.

C. No trapezoids are rhombuses: This statement is not true based on the diagram. The overlapping region indicates that there are trapezoids that are indeed rhombuses. Therefore, option C is incorrect.

D. No rhombuses are trapezoids: This statement is true based on the diagram. There is no overlap between the regions representing rhombuses and trapezoids, implying that no rhombus can be considered a trapezoid. Hence, option D is correct.

The value of such that = k * 180, where k is an integer, is the value at which cotangent is undefinable.

Cotangent, or cot, is one of the six standard trigonometric functions. Cotangent of an angle is defined as the ratio of the adjacent side to the opposite side of a right-angled triangle.

The value of cotangent is undefined when the denominator is zero. This implies that cotangent is undefined at angles where the value of sine is zero.

Since the sine function is periodic and has a period of 360 degrees, the values of sine repeat themselves after every 360 degrees.

For this reason, cotangent is undefined at angles such that θ = k * 180, where k is an integer.

That is, cotangent is undefined at 0°, 180°, 360°, and so on. It is also important to note that cotangent is a periodic function, and its values repeat every 180 degrees.

Therefore, cotangent is undefined at 0° + k * 180°, where k is an integer.

To summarize, the value of Θ at which cotangent is undefined is such that θ = k * 180, where k is an integer.

The time Jack left Santa Clara is 1 : 55 pm

A word problem in math is a math question written as one sentence or more. These statements are interpreted into mathematical equation or expression.

The time for Jack to walk to lose Altos is 25 min and he uses another 25mins to work to Palo alto.

Therefore, the total time he spent is

25mins + 25 mins = 50 mins

He arrived Palo at 2 :45 pm, therefore the time he left Santa Clare will be ;

2:45 pm = 14 :45

= 14:45 - 50mins

= 13:55

= 1 : 55pm

Given:

To find the factorization of the graph,

By factorization, we get

Hence option a) is the correct answer.

Assuming a transformation from f(t) = -6t², multiplying by 82.14 would result in a vertical stretch of the graph. Specifically, it would stretch the graph vertically by a factor of 82.14, making the rocket travel much higher than before.

Trajectory refers to the path that an object takes as it moves through space. In physics, trajectory is often used to describe the path of a projectile, which is an object that is launched into the air and moves under the influence of gravity alone.

The value h(t) = 82.14 represents the maximum height reached by the rocket during its flight. This value is obtained by multiplying the maximum height reached by the rocket (which can be found by solving f(t) = 0 to get the time when the rocket reaches its highest point) by the scaling factor of 82.14. So, the rocket is traveling very high, and h(t) represents the peak height of the rocket's trajectory.

Answer:

Step-by-step explanation:

1500+7y > 4700 can be solved algebraically to find the value of y that satisfies the inequality.

First, we need to isolate the variable y on one side of the inequality by subtracting 1500 from both sides:

1500 + 7y - 1500 > 4700 - 1500

Simplifying the left-hand side:

7y > 3200

Finally, we isolate y by dividing both sides by 7:

y > 3200/7

Therefore, the solution to the inequality is y > 457.14 (rounded to two decimal places).

The total number of students who graduated from the Cincinnati universities and colleges are 15382.

We are given that 6.76 % of Cincinnati college and university graduates majored in Registered Nursing.

The number of the Cincinnati college and university graduates who majored in Registered Nursing = 1026.

We need to find the total number of students that graduated from the Cincinnati universities and colleges altogether in 2016.

Let the total number of students be x.

ATQ:

6.67 % x = 1026

6.67 x = 102600

667 x = 10260000

x = 10260000 / 667

x = 15382.309

Rounding off to the nearest whole number is:

x = 15382.

Answer:

In mathematics, the extrema of a function refer to the maximum and minimum values that the function can take on. These values can be local extrema, which occur within a certain range of the function, or global extrema, which are the maximum and minimum values over the entire domain of the function.

To find the extrema of a function, one can use a variety of techniques, such as taking the derivative of the function and setting it equal to zero to find the points of stationary values, or using the second derivative test to determine whether a stationary point is a local maximum or minimum.

Interpreting the extrema of a function can provide valuable information about the behavior of the function. For example, the global maximum of a function might represent the highest possible value that the function can attain, while the global minimum might represent the lowest possible value. Local extrema can also be important, as they can indicate changes in the slope or concavity of the function, which can have important implications for applications such as optimization or modeling real-world phenomena.

the height of a binary tree is the number of edges in the longest path from the root to a leaf.The best-case height of a binary tree with seven nodes is 3.

A binary tree is a type of tree structure consisting of nodes that are connected by edges. The number of edges in the longest path from a binary tree's root to a leaf determines the tree's height.In the best-case scenario, the binary tree is perfectly balanced and each node has exactly two children. With seven nodes, the best-case height is three because each node has two children and three edges connect the root node to the leaves. This means that the longest path from the root to a leaf is three edges, resulting in a height of three.

The answer to your question is A. A convenience sample​ because this sampling type is people being chosen from the population of her school. We can also rule out the other options because of the following reasoning:

[✓] A. A convenience sample

-> This is the correct option. She is asking students at her school that are nearby.

[✗] B. A self-selected sample

-> This type is more like a poll, people volunteer for a self-selected sample, while here they are being asked

Step-by-step explanation:

a) Prove that nonsingular 2 by 2 matrices is not a vector space

2 nonsingular matrices are not closed when added together hence it is not a vector space ( i.e. their sum = singular and not nonsingular )

vector A = \(\left[\begin{array}{ccc}1&0\\0&1\\\end{array}\right]\)    +  vector B =  \(\left[\begin{array}{ccc}0&1\\1&0\\\end{array}\right]\) = \(\left[\begin{array}{ccc}1&1\\1&1\\\end{array}\right]\) ( singular vector )

2 singular 2 by 2 matrices is not  closed under addition, hence they are not a vector space. ( i.e. their sum = nonsingular )

Vector C = \(\left[\begin{array}{ccc}1&0\\0&0\\\end{array}\right]\)  + vector D = \(\left[\begin{array}{ccc}0&0\\0&1\\\end{array}\right]\) = \(\left[\begin{array}{ccc}1&0\\0&1\\\end{array}\right]\) ( nonsingular vector )
