using Pythagoras' identity in the right triangle
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
a² + 24² = 26²
a² + 576 = 676 ( subtract 576 from both sides )
a² = 100 ( take square root of both sides )

2079 [Optional] Set A Q.No. 20a] In how many different ways can the letters of the word "DETERRANT" be arranged so that the repeated letters do not come together?
There are 70,560 different ways to arrange the letters of the word "DETERRANT" so that the repeated letters do not come together.
How many ways the word "DETERRANT" be arranged so that the repeated letters do not come togetherThe word "DETERRANT" has 9 letters, out of which there are 2 E's, 2 R's, and 1 T.
To determine the total number of possible arrangements, we begin with 9! (9 factorial), which counts all possible arrangements if all letters are distinct.
We must, however, account for the repeated letters. For the two E's, we divide by 2, which is the number of different ways they can be arranged without changing the overall arrangement. Likewise, we divide by 2! for the two R's.
As a result, the total number of arrangements with repeated letters that do not come together is:
9! / (2! x 2!) - 8! / (2! x 2!) = 90720 - 20160 = 70560
Therefore, there are 70,560 different ways to arrange the letters of the word "DETERRANT" so that the repeated letters do not come together.

Find the area of the regular polygon below and round your answer to the nearest tenth.
Explain your reasoning. Show all your work.
1) What is the perimeter of the regular polygon?
2) What is the apothem length? Show all your work and explain how you found the apothem.
3) What is the area of the regular polygon? Show your work.
7 sides each side is 10 in long
The area of the regular polygon is 311.5 in2.
We are given that;
A polygon
Now,
To find the perimeter of the regular polygon, we need to multiply the number of sides by the length of each side. The polygon has 7 sides and each side is 10 in long, so the perimeter is 7 * 10 = 70 in.
To find the apothem length, we need to use some trigonometry.
The central angle is 360/7 degrees, since there are 7 equal angles in a regular polygon. Half of the side length is 5 in, since each side is 10 in long. The apothem is the adjacent side of the right triangle. We can use the tangent function to find the apothem: tan(360/14) = 5/a, where a is the apothem. Solving for a, we get a = 5/tan(360/14) ≈ 8.9 in.
To find the area of the regular polygon, we need to plug in the values of P and a into the formula A = (1/2)P*a.
A = (1/2)708.9 ≈ 311.5 in2.
Therefore, by the area the answer will be 311.5 in2.

A right rectangular prism measures 8 inches long, 12 inches high, and 6 inches deep. A half-sphere with a diameter of 2 inches is carved out of the prism. What is the approximate volume of the resulting composite figure?
Answer:
[tex]573.9 \text{ in}^3[/tex]
Step-by-step explanation:
First, we can find the volume of the rectangular prism using the formula:
[tex]V_\square = l \cdot w \cdot d[/tex]
where [tex]l[/tex] is the prism's length, [tex]w[/tex] is its width, and [tex]d[/tex] is its depth.
Plugging the given dimensions into the formula:
[tex]V_\square = 8 \cdot 12 \cdot 6[/tex]
[tex]V _\square= 96 \cdot 6[/tex]
[tex]\boxed{V_\square = 576 \text{ in}^3}[/tex]
Next, we can find the volume of the half-sphere using the formula:
[tex]V_\circ = \dfrac{2}{3} \pi r^3[/tex]
where [tex]r[/tex] (or [tex]d/2[/tex]) is the half-sphere's radius.
Plugging the given diameter value into the formula:
[tex]V_\circ = \dfrac{2}{3} \pi (2/2)^3[/tex]
[tex]V_\circ = \dfrac{2}{3} \pi (1)^3[/tex]
[tex]\boxed{V_\circ=\dfrac{2}{3}\pi \text{ in}^3}[/tex]
Finally, we can find the volume of the composite figure by subtracting the volume of the half-sphere from the volume of the rectangular prism.
[tex]V = V_\square - V_\circ[/tex]
[tex]V = 576 \text{ in}^3 - \dfrac{2}{3}\pi \text{ in}^3[/tex]
We can evaluate this using a calculator.
[tex]\boxed{V\approx 573.9 \text{ in}^3}[/tex]
The world famous gambler from Philadelphia, Señor Rick, proposes the following game of chance. You roll a fair die. If you roll a 1, then Señor Rick pays you $55. If you roll a 2, Señor Rick pays you $10. If you roll a 3, you win nothing. If you roll a 4 or a 5, you must pay Señor Rick $35, and if you roll a 6, you must pay Señor Rick $25. What is the expected value for this game if you pay $1 to play?
The expected value for this game, when you pay $1 to play, is -$4.00. This means that, on average, you can expect to lose $4.00 per game in the long run.
To calculate the expected value for the game, we need to multiply each outcome by its respective probability and then sum them up.
Let's calculate the expected value for each outcome:
Outcome 1: Roll a 1 and receive $55.
The probability of rolling a 1 on a fair die is 1/6.
Expected value = (1/6) × $55 = $9.17
Outcome 2: Roll a 2 and receive $10.
The probability of rolling a 2 on a fair die is 1/6.
Expected value = (1/6) × $10 = $1.67
Outcome 3: Roll a 3 and win nothing.
The probability of rolling a 3 on a fair die is 1/6.
Expected value = (1/6) × $0 = $0
Outcome 4: Roll a 4 or 5 and pay Señor Rick $35.
The probability of rolling a 4 or 5 on a fair die is 2/6 or 1/3.
Expected value = (1/3) × (-$35) = -$11.67 (negative because you have to pay)
Outcome 5: Roll a 6 and pay Señor Rick $25.
The probability of rolling a 6 on a fair die is 1/6.
Expected value = (1/6) × (-$25) = -$4.17 (negative because you have to pay)
Now, let's sum up the expected values:
Expected value = $9.17 + $1.67 + $0 - $11.67 - $4.17
= -$4.00
The expected value for this game, when you pay $1 to play, is -$4.00. This means that, on average, you can expect to lose $4.00 per game in the long run.

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 50 ft.
hl
What is the volume of the sphere?
The volume of a sphere can be calculated using the formula V = (4/3)πr³, where V is the volume and r is the radius.
Given that the sphere and the cylinder have the same radius and height, we can assume that the radius of both shapes is the same.
Let's denote the radius as 'r'. The volume of the cylinder is given as 50 ft³.
The volume of the cylinder is calculated using the formula V = πr²h, where h is the height.
Since the height of the cylinder is not given, we cannot determine the exact value of 'r' or calculate the volume of the sphere.
However, if we assume that the height of the cylinder is equal to its diameter (which is twice the radius), we can proceed with the calculation.
If the height of the cylinder is equal to 2r, the volume of the cylinder becomes:
50 = πr²(2r)
50 = 2πr³
Dividing both sides of the equation by 2π gives:
25 = πr³
Now, we can substitute this value of πr³ into the volume formula of the sphere:
V = (4/3)πr³
V = (4/3)(25)
V = 100/3
Therefore, if the height of the cylinder is equal to its diameter, the volume of the sphere would be 100/3 ft³. However, please note that this assumption might not necessarily be valid without further information about the relationship between the height and radius of the cylinder.
Answer: The Volume of the sphere is 100/3 cubic feet.
Step-by-step explanation:
It is clearly seen in the given figures, the height is two times the radius. Therefore, h is equal 2r.
We know that,
The volume of the sphere is π x r^2 x h. (r is radius and h is height)
So putting the values of height, h in the above formula, we get:
πxr^2x2r
= 2 * π * r^3.
= 2 * π * r^3 = 50
= π * r^3 = 25
We get, r^3 = 7.957747155
Therefore, r = 1.996472712
Now that we have the measure of the radius, we can find the volume of the sphere!
(4 / 3) * π * r^3
(4/3) * π * (1.996472712)^3
= (4/3) * π * 7.957747155
= (4/3) * π * (25 / π)
= (4/3) * 25
= 100/3 cubic feet.
