Which is a counterexample for the following biconditional: "A figure is a quadrilateral if and only if it
is a polygon"?

It is possible to construct a triangle whose sides are 10.2 cm 5.8 cm and 4.5 cm because the sum of two sides are greater than three sides.

In the given question, we have to check that it is possible to construct a triangle whose sides are 10.2 cm 5.8 cm and 4.5 cm.

The sum of the two sides must always be greater than the third side in order to determine whether or not the given sides may form a triangle.

To check this we firstly add the 10.2 and 5.8

10.2 + 5.8 > 4.5

16 > 4.5

Now we add 5.8 and 4.5

5.8 + 4.5 > 10.2

10.3 > 10.2

Now we add 10.2 and 4.5

10.2 + 4.5 > 5.8

14.7 > 5.8

Answer:

The correct answer is D. 225pi cm^3.

To find the volume of a cylinder, you use the formula:

V = πr^2h

Where V is the volume, π is pi, r is the radius of the base, and h is the height of the cylinder.

In this case, the height is 9cm, and the width is 10cm. To find the radius, we divide the width by 2:

r = 10cm / 2 = 5cm

Now we can plug in the values into the formula:

V = πr^2h

V = π(5cm)^2(9cm)

V = π(25cm^2)(9cm)

V = 225π cm^3

So the volume of the cylinder is 225π cm^3

Step-by-step explanation:

Answer: D)  225pi cm^3.

Step-by-step explanation:

By square root 5 this we get the value √5 = 2.2360…Or √5 ≈ 2.24 with correct two decimal number fraction .

1. First, the number 5 can be expressed as 5.00000000, or 5 = 5.00 00 00 00.

2.Take the number whose square is less than five. The perfect square of the number 2 is 4, which comes after the number 5.

3..Enter 2 in both the divisor and quotient places so that it may be multiplied by 2 to get the answer 4. Add 4 to 5 to obtain the answer, which is 1.

4.Write two zeros after one and add them to the quotient. Add the decimal point after the first zero.

5.Now multiply by 2 to make 4 in the divisor. Pick a number that will go next to 4, ensuring that the result of multiplying the combination with that number will be less than or equal to 100. In order to make 42 times 2 equal 84, which is less than 100, we shall use 2 in this instance. To get the remainder, take 100 out of it immediately. The remainder is therefore 16.

6.Repetition of Step 5 up to 4 places of decimals with the addition of two more zeros.

7.Ultimately, you arrive at the quotient value, which is 2.2360, or around 1.236.

In light of this, the value of root 5 is, √5 = 2.2360… Or √5 ≈ 2.24

Every possible input value results in exactly one output value in a function. "The output is a function of the input," we state. The domain is made up of the input values, while the range is made up of the output values.

What do you mean by relation of a function?

A relation that states that there should be only one output for each input is known as a function. Alternatively, we could say that a special sort of relation (a set of ordered pairs) that adheres to the rule that every X-value should be associated with only one y-value is known as a function.

To ascertain whether a graph accurately depicts a function, use the vertical line test. If there are multiple points where the vertical line intersects the graph, the graph is not a function.

choose 50 distinct numbers between 0 and 99. For starlings and geese, follow the same procedure.

Measurement of the likelihood that an event will occur or a claim is true is done via probability theory, a branch of mathematics. The probability of an occurrence is a number between 0 and 1, with 1 denoting certainty and 0 roughly indicating how likely it is that the event will occur. A probability is a numerical representation of how likely it is that a certain occurrence will take place. Probabilities can also be expressed as ranges of 0% to 100% or 0 to 1. the proportion of occurrences in a whole set of equally likely options that lead to a particular event relative to the entire number of outcomes.

The meridian at 180° longitude is commonly known as the International Date Line. As you pass the International Date Line, you either add a day (going west) or subtract a day (going east.)

The prime meridian and the International Date Line create a circle that divides Earth into the Eastern and Western Hemispheres.

The prime meridian has been set up in Greenwich, UK. It is an imaginary line that represents O degrees of longitude. This line, like all other meridians, runs from the North Pole to the South Pole and has the same length as all of the other meridians.

From the prime meridian, there are 180 degrees west and 180 degrees east. This is the line that divides the world in the Western and Eastern Hemispheres. The prime meridian is also the line from which time is counted either plus or minus, as it is at 0+ time zone, and everything east of it is plus, while everything west is minus.

Using the formula of Simple Interest, the value for the principal amount is obtained to be P = $1333.33.

What is Simple Interest?

Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time. Contrary to compound interest, where we add the interest of one year's principal to the next year's principal to compute interest, the principal amount under simple interest remains constant.

The value for Simple Interest is given as = $180

The value for rate is given as = 4.5%

The value for time is given as = 3 years

To find the value for Principal amount, follow the formula for Simple Interest -

SI = P R T/100

Where P is the principal amount, R is the rate and T is the time.

Substitute the values in the equation -

180 = (P × 4.5 × 3)/100

180 = 13.5P / 100

P = (180 × 100) / 13.5

P = 18000 / 13.5
