Explanation:
A hemisphere of radius 8 sits on a horizontal plane. A cylinder stands with its axis vertical, the center of its base at the center of the sphere, and its top circular rim touching the hemisphere. Find the radius and height of the cylinder of maximum volume.
The dimensions of the cylinder that has the maximum volume can be
found be finding the maximum value of the volume function.
[tex]\mathrm{The \ \underline{height \ of \ the \ cylinder \ of \ maximum \ volume \ is \ \dfrac{8}{\sqrt{3} }}}[/tex][tex]\mathrm{The \ \underline{radius \ of \ the \ cylinder \ of \ maximum \ volume \ is \ \dfrac{8 \cdot \sqrt{6} }{3}}}[/tex]Reasons:
The known parameter of the hemisphere are;
The radius of the hemisphere = 8
Required;
The radius and height of the maximum volume of the inscribed cylinder.
Solution:
Let h represent the height of the cylinder, and let r represent the radius of
the cylinder, we have;
r² + h² = 8²
Therefore;
r² = 8² - h² = 64 - h²
r² = 64 - h²
The volume of the cylinder, V = π·r²·h = π·(64 - h²)·h
V(h) = π·(64·h - h³)
At the maximum volume, we have;
[tex]\dfrac{dV(h)}{dh} = \dfrac{d}{dh} \left(\pi \cdot \left(64 \cdot h - h^3 \right) \right) = \pi \cdot \left(64 - 3 \cdot h^2 \right) = 0[/tex]
64 - 3·h² = 0
64 = 3·h²
[tex]h =\sqrt{\dfrac{64}{3} } = \dfrac{8}{\sqrt{3} }[/tex]
[tex]\underline{\mathrm{The \ height \ of \ the \ cylinder, \ h} = \dfrac{8}{\sqrt{3} }}[/tex]
[tex]r^2 = 64 - \dfrac{64}{3} = \dfrac{128}{3}[/tex]
[tex]r =\sqrt{\dfrac{128}{3}} = \dfrac{8 \cdot \sqrt{6} }{3}[/tex]
[tex]\underline{\mathrm{The \ radius \ of \ the \ cylinder, \ } r = \dfrac{8 \cdot \sqrt{6} }{3}}[/tex]

Julissa is printing out copies for a work training. It takes 4 minutes to print a color copy, and it takes 2 minutes to print a grayscale copy. She needs to print no fewer than 8 copies within 25 minutes. Which system of inequalities represents the number of color copies, x, and grayscale copies, y, that Julissa can print to meet her goal?.
The system of inequalities for Julissa can be given as 4x + 2y ≤ 25
and x + y ≥ 8.
What is a system of inequalities?
The system of inequalities is given with the use of the more than inequalities for the correspondence to one variable.
In the given system, the inequalities lies with the grayscale copies, and color copies with the time limit of 25 minutes and minimum number of 8 copies.
Let the number of color copies = x
The time taken to print each color copy = 4 minutes
Thus, the time taken to print x color copies = 4x
Let the number of gray scale copies = y
The time taken to print each gray scale copy = 2 minutes
Thus, the time taken to print y gray scale copy = 2y
Total copies printed = x + y
Maximum time taken to print x color copies and y grayscale copies = 25 minutes
So,
4x + 2y ≤ 25
and x + y ≥ 8

Explanation:
i took the test rn
From the data that we have here the total number of people that are known to work for 4 hours per shift is 2.
How to solve for the workersThe sum of all of these probabilities would be equal to 1. Hence we would have:
0.1+x+0.14+0.36+0.3+0,06 = 1
x + 0.96 = 1
x = 1 - 0.96
x = 0.04
The total number of people that is said to work for this manager is said to be 50.
50 x 0.04
= 2
Therefore the total number that work at 4 hours per shift is 2.

A small fair charges an admission fee for children and adults. The cost for admission is $3 per adult and $2 per child. On a certain day, total admission fees were $900, and 350 people attended the fair. How many children attended the fair that day? 80 children 150 children 200 children 320 children.
150 children attended the fair for that day if $900, and 350 people attended the fair, hence option b is correct.
What is the number of children attended the fair?Detailed explanation:
Let's say there are x youngsters and y grownups.
350 persons in all visited the fair, thus.
So, x + y = 350.
In addition, fees per kid are $2 and fees per adult are $3.
Since, $900 is assumed to represent the entire sales.
So, 2x + 3y = 900
Consequently, we have the equation system,
2x + 3y = 900
x + y = 350
Now let's resolve the equations.
x + y = 350 ⇒ y = 350 - x
The result is that 2x + 3y = 900 2x + 3(350 -x) = 900 2x + 1050 - 3x = 900 -x = -150 x = 150.
The result is that y = 350 - x y = 350 - 150 y = 200.
Therefore, As a result, 150 children and 200 adults, respectively, visited the fair.

A chamber contains equal molar amounts of c₂h₂, ch₄, and h₂. If the total chamber pressure is 5. 00 atm, then the partial pressure of c₂h₂ is:.
Answer:
I don't know answer what
The partial pressure of c₂h₂ is25 atm.
What is partial pressure?When more than one gas is present in a container, each gas exerts pressure, which is known as partial pressure. Its partial pressure refers to the pressure of any gas inside the container.
Partial pressures can be calculated in one of two ways:
To determine the individual pressure of each gas in a mixture, use PV = nRT. Determine the proportion of pressure from the total pressure that may be assigned to each individual gas by using the mole fraction of each gas.When there is a combination of two or more gases in a given volume, the pressure created by each individual gas in the mixture is expressed using the phrase partial pressure.
The partial pressures of the individual gases make up the total pressure of the gas combination. P1 + P2 + P3 = Ptot = Pi

How many square feet of glass are needed to cover the skywalk floor? (round your final answer to 1 decimal place and any intermediate calculations to 2 decimal places. Be sure to include units. ).
The area of the skywalk floor is the amount of space it occupies
The area of the skywalk floor is 1728.1 square feet
From the complete question, we have the following parameters
The outer diameter is 65 feet
This is represented as: [tex]\mathbf{d_2 = 65}[/tex]
The inner diameter is calculated as follows:
[tex]\mathbf{d_1 = 65 - 2 * 10}[/tex]
[tex]\mathbf{d_1 = 45}[/tex]
So, the area of the skywalk floor is the difference between the areas of the two semicircles.
This is represented as:
[tex]\mathbf{Area = \frac{\pi d_2^2}{4} - \frac{\pi d_1^2}{4}}[/tex]
Rewrite as:
[tex]\mathbf{Area = \frac{\pi}{4}(d_2^2 - d_1^2)}[/tex]
So, we have:
[tex]\mathbf{Area = \frac{3.142}{4}(65^2 - 45^2)}[/tex]
[tex]\mathbf{Area = \frac{3.142}{4}(2200)}[/tex]
Simplify
[tex]\mathbf{Area = 3.142 \times 550}[/tex]
[tex]\mathbf{Area = 1728.1}[/tex]
Hence, the area of the skywalk floor is 1728.1 square feet

Answer:
Correct answer is C) $14.200.39
Explanation:
we know that
The simple interest formula is equal to
I = Prt
P = I / (rt)
where
I is the amount of money in interest
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
in this problem we have
t = 9 years
I = $5,896
P = ?
r = 0.0692
substitute in the formula above
P = 5,896/ (0.0692 ÷ 6) = $14,200.39
