We know the volume is 24, we can rearrange the formula to find the height: h = V/A. Plugging in the given values, we get h = 24/πr^2.
If the volume of a cylinder B2 is 24 cubic centimeters, there are a few things we can determine about the cylinder's dimensions. To find the radius of the cylinder, we first need to calculate the area of the base.
We can use the formula A = πr^2, where A is the area and r is the radius. If we know the volume of the cylinder, we can use the formula V = Ah, where V is the volume,
A is the area of the base, and h is the height of the cylinder. However, we do not have enough information to find the radius, as there are infinite combinations of radius and height that can give us a volume of 24 cubic centimeters.

In circle J with m/HJK = 48 and HJ = 11 units, find the length of arc HK.
Round to the nearest hundredth.
H
K
The length of arc HK is approximately 3.86 units.
To find the length of arc HK, we need to know the circumference of circle J.
The formula for the circumference of a circle is C = 2πr,
where C is the circumference and r is the radius.
Since we don't have the radius directly given, we can find it using the given information.
We know that the measure of angle HJK is 48 degrees, and HJ is 11 units. The angle at the center of a circle is twice the angle at the circumference that intercepts the same arc.
Therefore, angle HJK at the center of the circle intercepts an arc HK with the same measure.
So, the circumference of the circle is C = 2πr = 2π(11 units).
To find the length of arc HK, we need to find the fraction of the circumference represented by the angle HJK.
We know that the total angle at the center of a circle is 360 degrees (the full circumference), so the fraction of the circumference represented by angle HJK is 48/360.
The length of arc HK is then calculated by multiplying the fraction of the circumference represented by the angle HJK by the total circumference of the circle:
Arc HK = [tex](48/360) \times 2\pi (11 units)[/tex]
Calculating this value, we get:
Arc HK ≈[tex](48/360) \times 2 \pi \times 11[/tex] ≈ 1.234π
To find the numerical value, we can approximate π as 3.14:
Arc HK ≈[tex]1.234 \times 3.14[/tex] ≈ 3.86 units (rounded to the nearest hundredth)

For n = 1:
u_1 = 1/(7(1) - 2) = 1/5
For n = 2:
u_2 = 1/(7(2) - 2) = 1/12
For n = 3:

In 5 times, Dian's age will be x 8 5, and his family's age will be x 5.
The problem also states that in 5 times, Dian will be doubly as old as his family,
so we can set up the equation
x+ 8+ 5 = 2( x +5)

If the three digits of a three-digit number are multiplied ou get 135. Which result to you get, by adding the three digits?
Answer:
Let's call the three digits of the three-digit number "a", "b", and "c". Since the product of the digits is 135, we know that:
a * b * c = 135
We need to find the value of a + b + c. One way to approach this is to try out different combinations of digits that multiply to 135 and see which one adds up to the correct sum. The possible combinations are:
1 * 3 * 45 = 135 -> 1 + 3 + 45 = 49
1 * 5 * 27 = 135 -> 1 + 5 + 27 = 33
1 * 9 * 15 = 135 -> 1 + 9 + 15 = 25
3 * 5 * 9 = 135 -> 3 + 5 + 9 = 17
So, the only combination of digits that adds up to a three-digit number is 1, 3, and 45, which add up to 49. Therefore, the answer is 49.

Consider a tree T with n vertices, where n is an odd integer greater than or equal to 3. Let v be a vertex of T. Prove that there exists a vertex u in T such that the distance between u and v is at most (n-1)/2.
There exists a vertex u in tree T such that the distance between u and v is at most (n-1)/2.
To prove that there exists a vertex u in tree T such that the distance between u and v is at most (n-1)/2, we can use the concept of the longest path in a tree and the properties of odd integers.
First, let's consider the longest path in the tree T.
Since the tree has n vertices, the longest path can have at most n-1 edges.
Let's denote this longest path as P.
Since n is an odd integer, we have n = 2k + 1, where k is a non-negative integer.
This implies that n-1 = 2k, which is an even number.
Now, consider the middle vertex x of the longest path P.
If P has an odd number of vertices, then x is unique.
If P has an even number of vertices, then there are two possible middle vertices, but we can choose any one of them.
Next, let's consider the distance between v and x along the longest path P. Since x is the middle vertex, this distance can be at most (n-1)/2.
This is because the longest path P divides the tree into two parts, each containing (n-1)/2 vertices at most.
Now, let's consider the subtree rooted at x, which consists of all vertices that can be reached from x.
Since the distance between v and x is at most (n-1)/2, it implies that v is within this subtree.
Therefore, we have found a vertex u (in this case, x) in the subtree rooted at x such that the distance between u and v is at most (n-1)/2.
By proving the existence of such a vertex u, we have shown that for any vertex v in the tree T, there exists a vertex u in T such that the distance between u and v is at most (n-1)/2.

What is the volume of this cone? Use π =3.14 and round to the nearest hundredth
Answer:
If the height and radius of a cone are both 9 yards, then you can use the formula for the volume of a cone to calculate its volume. The formula for the volume of a cone is V = (1/3)πr^2h, where r is the radius of the base and h is the height of the cone. Plugging in the values for r, h, and π gives us:
V = (1/3)πr^2h
= (1/3)(3.14)(9 yd)^2(9 yd)
= (1/3)(3.14)(81 yd^2)(9 yd)
= (1/3)(254.34 yd^3)
≈ 84.78 yd^3
So, the volume of a cone with a height and radius of 9 yards is approximately 84.78 cubic yards, rounded to the nearest hundredth.

When simplifying a rational expression in the form ( a − b ) / ( a + b ), it always equals - 1.
True or False
The statement that the rational expression ( a − b ) / ( a + b ) always equals -1 is incorrect, it does not hold true for all values of a and b. Only specific values that satisfy ( a - b ) = -( a + b ) will lead to the result -1.
Explanation:The statement in the question is not correct. That is, it is False. The rational expression in the form ( a − b ) / ( a + b ) does not always equal - 1. For example, if a = 5 and b = 3, the rational expression ( a − b ) / ( a + b ) becomes ( 5 - 3 ) / ( 5 + 3 ), which evaluates to 2 / 8 = 0.25, not -1. The statement would only be true if (a - b) = -(a + b), which is not an assumption we can make for all values of a and b. So, while simplifying a rational expression it is necessary to substitute the values and check it out.

Answer: All of the values for x would make the equation FALSE.
Step-by-step explanation:
To see if each value would fit x for this equation, we will need to check each of them.
If you said x = 1 would fit this equation, it would be 7 < 3 - 1. This would be false because when you evaluate this equation, it would be 2 is greater or equal to 7 which isn't true.
If you said x = 5 would fit this equation, it would be 7 < 3 - 5. This would be false because when you evaluate this equation, it would be -2 is greater or equal to 7 which also isn't true.
If you said x = -3 would fit this equation, it would be 7 < 3 - -3. This would be false because when you evaluate this equation, it would be 6 is greater or equal to 7 which is really close, but it isn't true.
Therefore, none of these values for x would fit this equation at all in any way. The value of x would have to be -4 or more to make this statement true. Hope this helps!
