The total surface area of the cylindrical brass pipe, including the internal surface area, is [tex]10841π cm^2[/tex], where π is approximately 3.14159.

To calculate the total surface area of the cylindrical brass pipe, we need to consider both the external and internal surface areas.

The external surface area of a cylinder is given by the formula:

A_external =[tex]2πrh + πr^2[/tex]

Where:

r is the radius of the outer surface (half of the outside diameter), which is 10 cm / 2 = 5 cm

h is the height of the cylinder, which is given as 600 cm

Plugging in the values:

A_external = [tex]2π(5 cm)(600 cm) + π(5 cm)^2[/tex]

= [tex]2π(3000 cm^2) + π(25 cm^2)[/tex]

= [tex]6000π cm^2 + 25π cm^2[/tex]

= [tex]6025π cm^2[/tex]

The internal surface area of a cylinder is given by the formula:

A_internal = [tex]2πrh + πr^2[/tex]

Where:

r is the radius of the inner surface (inside radius), which is given as 4 cm

h is the height of the cylinder, which is given as 600 cm

Plugging in the values:

A_internal = [tex]2π(4 cm)(600 cm) + π(4 cm)^2[/tex]

= [tex]2π(2400 cm^2) + π(16 cm^2)[/tex]

= [tex]4800π cm^2 + 16π cm^2[/tex]

= [tex]4816π cm^2[/tex]

To find the total surface area, we add the external and internal surface areas:

Total surface area = A_external + A_internal

= [tex]6025π cm^2 + 4816π cm^2[/tex]

= [tex]10841π cm^2[/tex]

Therefore, the total surface area of the cylindrical brass pipe, including the internal surface area, is [tex]10841π cm^2[/tex], where π is approximately 3.14159.

Answer:

miles per hour

Step-by-step explanation:

speed can be define as the rate of distance covered in a given time.

i.e speed = [tex]\frac{distance}{time}[/tex]

Given that the height (distance) of the empire state building = 1454 feet.

a. For feet per second;

distance = 1454 feet

time = 1 second

speed = [tex]\frac{1454}{1}[/tex]

           = 1454 feet/second

b. For miles per hour,

1 feet =  0.000189394 mile

Thus, 1454 feet = 0.2753788 mile

distance = 0.2753788 mile

time = 1 hour

speed = [tex]\frac{0.2753788}{1}[/tex]

           = 0.2753788 miles/hour

Comparing the two units of measurement, miles per hour is more reasonable. This is because the penny can not move at that very high speed to hit the ground within 1 second when dropped.

The equation in vertex form is y = 2(x+3)² + 1. The vertex is (-3,1), the axis of symmetry is x = -3, and the direction of opening is upwards.

The vertex form of the equation is y = a(x-h)^2 + k, where (h, k) is the vertex. The axis of symmetry is x = h, and the direction of opening is determined by the value of a.

Using this formula, let us write each equation in vertex form and then identify the vertex, axis of symmetry, and direction of opening.

1. y = x² + 8x + 18

To write this equation in vertex form, we need to complete the square. y = x² + 8x + 18 is equivalent to y = (x+4)² - 2. Therefore, the equation in vertex form is y = (x+4)² - 2.

The vertex is (-4,-2), the axis of symmetry is x = -4, and the direction of opening is upwards.2

. y = -x² - 12x - 36To write this equation in vertex form, we need to complete the square. y = -x² - 12x - 36 is equivalent to y = -(x+6)² - 12. Therefore, the equation in vertex form is y = -(x+6)² - 12.

The vertex is (-6,-12), the axis of symmetry is x = -6, and the direction of opening is downwards.3. y = 2x² + 12x + 13To write this equation in vertex form, we need to complete the square. y = 2x² + 12x + 13 is equivalent to y = 2(x+3)² + 1.

Answer:

3.5 * 10^-4 centimeters

Step-by-step explanation:

Here, we have one uranium atom having a diameter of 3.5 * 10^-8 centimeters.

We now want to find the sum of 10,000 uranium atoms diameters

Mathematically;

That would be ;

3.5 * 10^-8 * 10,000

But 10,000 = 10^4

Thus, we have

3.5 * 10^-8 * 10^4

= 3.5 * 10^-4 centimeters

The Perimeter of Harmony's new mural is 13.4 feet.

To determine the perimeter of Harmony's new mural, we need to use the formula for the perimeter of a rectangle, which is:P = 2l + 2w

where P represents the perimeter, l represents the length, and w represents the width of the rectangle. The units of measurement are in feet.

Given that the rectangular mural measures 1.3 feet by 4.8 feet, we can plug these values into the formula to find the perimeter of the original mural:P = 2(1.3) + 2(4.8)P = 2.6 + 9.6P = 12.2

Therefore, the perimeter of the original mural is 12.2 feet.

Now, Harmony creates a new mural that is 0.6 feet longer than the original mural. This means that the length of the new mural is 1.3 + 0.6 = 1.9 feet.

To find the perimeter of the new mural, we need to plug this new length into the same formula:P = 2l + 2wP = 2(1.9) + 2(4.8)P = 3.8 + 9.6P = 13.4

Therefore, the perimeter of Harmony's new mural is 13.4 feet.

The graph that represents the linear inequality y < -2x + 3 is graph B

The set of solutions to a linear inequality are represented graphically on a coordinate plane. It makes the area or areas that satisfy the inequality easier to visualize.

The linear equation that results from changing the inequality sign to an equal sign is the equation that is commonly graphed first when a linear inequality has to be represented. The coordinate plane is split into two regions by this linear equation: one zone where the linear equation holds true, and another region where it does not.

Next, we determine which side of the line represents the solution set for the inequality. This is determined by the inequality sign (<, >, ≤, ≥) and the given inequality's conditions.

To solve this problem, we can simply plot this using a graphing calculator ;

Answer:

48

Step-by-step explanation:

First 4 is 2/3 of 6 feet

Thus 32 is 2/3 of x

How do we find X

32 divided by 2 is 16

16 plus 32 = 48

Answer:

<a = 90°   (180-90 supplementary angle)

<b = 90°   (180-90 supplementary angle)

<d = 48°   (180-132 supplementary angle)

<e = 132°  (opposite angle)

<c = 42°     (interior angles of a triangle equal 180.  180-48-90=42)

Step-by-step explanation:

<a = 90°   (180-90 supplementary angle)

<b = 90°   (180-90 supplementary angle)

<d = 48°   (180-132 supplementary angle)

<e = 132°  (opposite angle)

<c = 42°     (interior angles of a triangle equal 180.  180-48-90=42)

Multiple triangles would be formed by the combination of 2 cm, 8 cm, and 10 cm.

To have a triangle, three sides of a polygon must be present. Additionally, each side must be less than the total of the other two sides added together to form a triangle.

Consider the following choices as a result:

A: 45 degrees, 82 degrees, 53 degrees.

We don't know the size of the triangle's sides, thus we can't say if it's going to create multiple triangles

.B: 5 degrees, 122 degrees, 61 degrees

This set of degrees won't result in a triangle because the angles add up to 188 degrees, which is greater than 180 degrees, the sum of the interior angles of a triangle.

C: 2 cm, 8 cm, 10 cm

The sum of 2 cm + 8 cm = 10 cm.

As a result, it is impossible for a triangle to be formed since 2 + 8 < 10.D: 10 in, 20 in, 75 degreesTwo sides of the triangle are known, however the angle between them is unknown, therefore it is impossible to tell if multiple triangles will form.

Option C is the only choice that would result in multiple triangles. The side lengths of a triangle are 2 cm, 8 cm, and 10 cm. It is impossible to form a triangle with 2 cm and 8 cm because they are too short to form a triangle, however if you switch the values and compare 8 cm and 10 cm, a triangle is formed.

Answer:

v = 55.5

Step-by-step explanation:

23 = -81 - 7 + 2v

23 = -88 + 2v

23 + 88 = -88 + 88 + 2v

111 = 0 + 2v

111 = 2v

111 ÷ 2 = 2v ÷ 2

55.5 = 1v

55.5 = v

Answer:

v = 55.5

Step-by-step explanation:

23 = -81 - 7 + 2v

1. Simplify by combining like terms

23 = -88 + 2v

2. Isolate the variable by adding 88 to both sides

23 + 88 = -88+ 88 +2v

23 + 88 = 2v

3. Combine like terms

111 = 2v

4. Solve for v by dividing both sides by 2

111/2 = 2v/2

55.5 = v

Answer:

the answer is d

Step-by-step explanation:

f(-3) ≠ f(3) and f(-3) ≠ -f(3), which means that the function f does not satisfy the properties required for it to be even or odd.

To determine whether the function f is even, odd, or neither, we need to evaluate the symmetry of the function with respect to the y-axis and the origin.

For a function to be even, it must satisfy the property f(x) = f(-x) for all values of x in the function's domain. This means that if we substitute -x for x in the function, we should obtain the same output as when we evaluate the function at x.

For a function to be odd, it must satisfy the property f(x) = -f(-x) for all values of x in the function's domain. This means that if we substitute -x for x in the function, we should obtain the negative of the output we obtain when we evaluate the function at x.

Let's evaluate the function f using the given points (-3,5) and (3,-5):

For the point (-3,5):

f(-3) = 5

For the point (3,-5):

f(3) = -5

We can see that f(-3) ≠ f(3) and f(-3) ≠ -f(3), which means that the function f does not satisfy the properties required for it to be even or odd.

We can conclude that the function f is neither even nor odd.
