Explanation:
The triangular face has area of base*height/2 = 8*2/2 = 16/2 = 8 square feet.
Multiply this with the depth of the prism to get 8*12 = 96 cubic feet
----------
For any prism, the volume formula is
V = (area of base)*(depth of prism)
The term "depth" can be replaced with "height" and it's the same idea.
In this problem, we have a triangular prism because the parallel sides are triangles.

Restless Leg Syndrome and Fibromyalgia
People with restless leg syndrome have a strong urge to move their legs to stop uncomfortable sensations. People with fibromyalgia suffer pain and tenderness in joints throughout the body. A recent study indicates that people with fibromyalgia are much more likely to have restless leg syndrome than people without the disease. The study indicates that, for people with fibromyalgia, the probability is 0.33 of having restless leg syndrome, while for people without fibromyalgia, the probability is 0.03. About 2% of the population has fibromyalgia. Create a tree diagram from this information and use it to find the probability that a person with restless leg syndrome has fibromyalgia.
Answer:
The probability that a person with restless leg syndrome has fibromyalgia is 0.183.
Step-by-step explanation:
Denote the events as follows:
F = a person with fibromyalgia
R = a person having restless leg syndrome
The information provided is as follows:
P (R | F) = 0.33
P (R | F') = 0.03
P (F) = 0.02
Consider the tree diagram attached below.
Compute the probability that a person with restless leg syndrome has fibromyalgia as follows:
\(P(F|R)=\frac{P(R|F)P(F)}{P(R|F)P(F)+P(R|F')P(F')}\)
\(=\frac{(0.33\times 0.02)}{(0.33\times 0.02)+(0.03\times 0.98)}\\\\=\frac{0.0066}{0.0066+0.0294}\\\\=0.183333\\\\\approx 0.183\)
Thus, the probability that a person with restless leg syndrome has fibromyalgia is 0.183.

At the Manchester Golf Tournament, the leader board shows Farrah's score as 5 on the front nine and 8 on the back nine.
Farrah's total score for both rounds is?
Farrah's total score for both rounds will be -3.
Since the leader board shows Farrah's score as 5 on the front nine, this will be: +5
Since the leader board shows Farrah's score as 8 on the back nine, this will be -8. Then we'll add both together to get the total score which will be:
= 5 + (-8)
= 5 - 8
= -3
His total score will be -3.

The area of the triangle is 97.07 units².
Given is a triangle we need to find the area,
So, let the triangle be ABC and the altitude be AD.
Using the trigonometric ratios,
Sin 52° = AB / AD
Sin 52° = 9 / AD
AD = 9 / Sin 52°
AD = 11.42
Now,
Tan 26° = DC / AD
Tan 26° = DC / 11.42
DC = 5.56
Also,
Cos 26° = AD / AC
Cos 26° = 11.42 / AC
AC = 12.7
BC = 11.42 + 5.56
BC ≈ 17
Now, the sides are BC = 17, AC = 12.7 and AB = 9,
The area of the triangle = 1/2 x BC x AD = 1/2 x 17 x 11.42
= 5.71 x 17
= 97.07
Hence the area of the triangle is 97.07 units².

Find the charge density that must be glued to the surface of an insulating, cubical box (0 ≤ x, y, z ≤ a) so the electric field everywhere outside the box is identical to the field produced by a (fictitious) point charge Q located at the center of the box. o(x,y) -Q A grounded box with a point charge - Q at its center.
The charge density that must be glued to the surface of an insulating, cubical box is\(σ = dq / dA = Q / a^2\)
Gauss's law can be applied to determine the charge density on the box's surface. According to Gauss's law, the charge enclosed by a closed surface determines how much electric flux passes through it.
Take into account a box-centred spherical Gaussian surface with radius r. By virtue of symmetry, the electric field must be radial and have a constant strength over the entire sphere. The flux through the sphere is therefore given by:
\(Φ = E(r) * 4πr^2\)
where E(r) is the electric field's strength at radius r.
The point charge Q in the box's centre is now equal to the charge contained within the sphere. So, according to Gauss's law:
\(Φ = Q / ε0\)
When the permittivity is 0
where 0 represents the free space permittivity.
The electric field outside the box should be the same as the electric field created by a point charge Q in the middle of the box. In order to ensure that the flux through any spherical surface outside the box is equal, we must choose the charge density on the box's surface.
Take into account a tiny element with surface area dA on the box's surface. The electric field caused by this element of charge at point P outside the box can be expressed as:
\(dE = (1 / 4πε0) * dq / r^2\)
where r is the distance between the element and point P and dq is the charge on the tiny surface-area element.
We integrate across all the minor components of the surface area of the box to determine the total electric field at point P caused by the entire surface of the box:
\(E = dE = (1 / 4.0)*dq / r2\)
Now, we want this electric field to match the electric field caused by point charge Q in the box's centre, which is determined by:
\(E' = Q / (4πε0r^2)\)
As a result, we have:
\(E = E': (1 / 4 0) * dq / r2 = Q / (4 0 r2)\)
To solve for dq, we obtain:
\((Q / a2)*dA = dq\)
therefore, the charge density on the box's surface is given by:
\(σ = dq / dA = Q / a^2\)
To produce the same electric field outside the box as that caused by a point charge Q at the centre of the box, we must glue a uniform charge density of Q / a2 on the box's surface.

The solution of the differentiated equation is dy/dx = -6x⁵
How to differentiate the equation?From the question, we have the following equations that can be used in our computation:
x = ⁶√t
y = 8 - t
To start with:
We need to make the variable t the subject of the formula in the equation x = ⁶√t
Make t the subject
So, we have
t = x⁶
Substitute t = x⁶ in the equation y = 8 - t
y = 8 - x⁶
The rule of first principle of differentiation is represented as
If y = axⁿ, then dy/dx = naxⁿ⁻¹
Using the above as a guide, we have
y = 8 - x⁶
dy/dx = 0 * 8x⁰⁻¹ - 6 * x⁶⁻¹
Evaluate the difference
So, we have
dy/dx = 0 * 8x⁻¹ - 6 * x⁵
Evaluate the products
So, we have
dy/dx = 0 - 6x⁵
Evaluate the sum
So, we have
dy/dx = -6x⁵
Hence, the equation result is dy/dx = -6x⁵

The speed of the plane is equal to 120 mph.
What is speed?In Mathematics and Geometry, speed is the distance covered by a physical object per unit of time. This ultimately implies that, speed can be measured by using miles per hour (mph).
Mathematically, the speed of any a physical object can be calculated by using this formula;
Speed = distance/time
Time = distance/speed
Let the variable s represent the speed of the plane in miles per hour. Therefore, an equation that models the situation can be written as follows;
240/s = 80/s - 80
80s = 240s - 19200
19200 = 160s

Let f left parenthesis x right parenthesis equals x cubed minus x squared minus 1 and x subscript 0 equals 1 . To the nearest three decimal places, find x subscript 5 using Newton's method of approximation.
The value of \(x_5\), rounded to the nearest decimal place using Newton's method of approximation is 1.466.
The correct answer is option B.
To find the value of \(x_5\)using Newton's method of approximation, we need to iterate the following formula:
\(x_(_n_+_1_) = x_n - f(x_n) / f'(x_n)\)
where f'(x) represents the derivative of the function f(x). Let's calculate the values step by step.
Given function: f(x) = \(x^3 - x^2 - 1\)
Step 1: Find the derivative of f(x)
f'(x) = \(3x^2 - 2x\)
Step 2: Initialize the starting value
\(x_0\)= 1
Step 3: Calculate \(x_1\)
\(f(x_0) = f(1) = (1^3) - (1^2) - 1 = 1 - 1 - 1 = -1\)
\(f'(x_0) = f'(1) = (3(1^2)) - (2(1)) = 3 - 2 = 1\)
\(x_1 = x_0 - f(x_0) / f'(x_0)\)
= 1 - (-1) / 1
= 2
Step 4: Calculate \(x_2\)
\(f(x_1) = f(2) = (2^3) - (2^2) - 1 = 8 - 4 - 1 = 3\)
\(f'(x_1) = f'(2) = (3(2^2)) - (2(2)) = 12 - 4 = 8\)
\(x_2 = x_1 - f(x_1) / f'(x_1)\)
= 2 - 3 / 8
= 1.625
Step 5: Repeat the process until we reach \(x_5\)
Performing the calculations for \(x_3, x_4, andx_5\), we find:
\(x_3\) ≈ 1.465
\(x_4\) ≈ 1.466
\(x_5\)≈ 1.466
After applying Newton's method of approximation to the function f(x) = \(x^3 - x^2 - 1,\)starting with,\(x_0 = 1,\) we iteratively calculated the values of \(x_1, x_2, x_3, x_4, and x_5\). The final approximation, \(x_5\), is approximately 1.466 when rounded to the nearest decimal place. This aligns with option B as the correct answer.

A new concert venue just opened in downtown Houston and they are in the process
of deciding how many tickets they can sell for each show. The venue has three levels,
two general admission that only have standing room, and one level with 150 seats.
The venue thinks each person will occupy 2.25 ft.
.
• The first level of standing room is a square with one side measuring 75ft.
The second level, also standing room, is a rectangle measuring 100' by 50' ft.
. The third level has 150 seats.
How many tickets can they sell for the first level?
Answer:
2500
Step-by-step explanation:
Dimensions of first level
Length = Breadth = 75 ft (since it is a square)
It is assumed that a person will occupy \(2.25\ \text{ft}^2\)
Area of first level
\(75\times 75=5625\ \text{ft}^2\)
When the area of the level is divided by the area of one person then we will get the number of people that can occupy the room or the number of tickets that can be sold.
\(\dfrac{5625}{2.25}=2500\)
The number of tickets that can be sold for the first level is 2500.
