The base, lateral area and surface area is B = 96 cm², L = 499.2 cm²,S = 691.2 cm²
What is Lateral Area ?The lateral area for the triangular prism is the sum of all three areas. Thus, the formula for lateral area of triangular prism, Lateral surface area of triangular prism (LSA) = ah + bh + ch (or) (a + b + c) h.
To find the lateral area (L) of this solid, we need to calculate the area of the four rectangles that make up the sides of the solid. Since each rectangle has a height of 10.4 cm and a width of 12 cm, the area of one rectangle is:
A = 10.4 cm * 12 cm = 124.8 cm²
Since there are four rectangles, the total lateral area is:
L = 4 * A = 4 * 124.8 cm² = 499.2 cm²
To find the surface area (S) of the solid, we need to add the lateral area to the area of the two circular bases. The base area is given as 96 cm², so the area of both bases is:
A = 2 * 96 cm² = 192 cm²
Therefore, the total surface area is:
S = L + A = 499.2 cm² + 192 cm² = 691.2 cm²
Rounding to the nearest tenth, we have:
B = 96 cm²
L = 499.2 cm²
S = 691.2 cm²

a ___________ is an inclined plane wrapped around a cylinder
A "threaded screw" or a "helical screw" is an inclined plane wrapped around a cylinder.
This unique configuration allows screws to convert rotational motion into linear motion, making them essential components in various applications such as fastening objects, lifting loads, adjusting mechanisms, and transmitting power.
An inclined plane is a flat surface that is angled or tilted. It allows for easier movement of objects by reducing the force required to overcome vertical displacement. When this inclined plane is wrapped around a cylinder in a spiral or helical shape, it forms a threaded screw.
The calculation is not applicable in this case as it involves understanding the concept and structure of a threaded screw rather than performing numerical calculations.
An inclined plane wrapped around a cylinder is known as a threaded screw or helical screw. This unique configuration allows screws to convert rotational motion into linear motion, making them essential components in various applications such as fastening objects, lifting loads, adjusting mechanisms, and transmitting power.

Julianne is using a biking app that compares his position to a simulated bike or traveling Julianne’s target speed. When Julianne is behind the simulated biker he has a negative position. I took a screenshot of the problem I am having difficulty with.
Given
\(\begin{gathered} Speed=20\frac{km}{h} \\ Time\text{ }taken=15\text{ }minutes \\ Initial\text{ }distance=2\frac{1}{4}km \end{gathered}\)To find:
The average speed of Julian.
Explanation:
It is given that,
\(\begin{gathered} Speed=20\frac{km}{h} \\ Time\text{ }taken=15\text{ }minutes \\ Initial\text{ }distance=2\frac{1}{4}km \end{gathered}\)That implies,
\(\begin{gathered} Distance\text{ }traveled=Speed\times Time \\ =20\frac{km}{h}\times15minutes \\ =20\frac{km}{h}\times15(\frac{1}{60})h \\ =20\frac{km}{h}\times\frac{1}{4}h \\ =5km \end{gathered}\)Therefore,
\(\begin{gathered} Average\text{ }speed=\frac{Final\text{ }distance-Initial\text{ }distance}{Time\text{ }taken} \\ =\frac{(5-2\frac{1}{4})km}{\frac{1}{4}h} \\ =\frac{5-\frac{9}{4}}{\frac{1}{4}}\frac{km}{h} \\ =\frac{\frac{20-9}{4}}{\frac{1}{4}}\frac{km}{h} \\ =11\frac{km}{h} \end{gathered}\)Hence, the average speed of Jean is 11 km/h.
Howard I must add 5 tiles to two of the sides and 3 tiles to th other two sides. The number of additional tiles addec to the Design 2 square floor design is 2(3+2)+2*3. Expression:
The expression of the additional tiles added to Design 2 square floor design is (8x + 15).
Let 'x' be the length of a side of the square floor design. Then, the total number of tiles required for the square floor design is given by \(x^2\)
Now, if Howard must add 5 tiles to two of the sides and 3 tiles to the other two sides, then the dimensions of the new square will be (x + 5) and (x + 3). Thus, the total number of tiles required for the new square will be: (x + 5) × (x + 3).
In order to determine the expression for the number of additional tiles added to Design 2 square floor design, we will subtract the number of tiles required for the original square floor design from the number of tiles required for the new square.
Thus, the expression for the number of additional tiles added to Design 2 square floor design is given by: \((x + 5) \times (x + 3) - x^2\)
Now, we will simplify the above expression: \(x^2 + 3x + 5x + 15 - x^2\)
So, additional tiles added to Design 2 square floor design = 8x + 15
Therefore, the expression for the number of additional tiles added to Design 2 square floor design is: (8x + 15).

suppose one painter can paint the entire house in twelve hours, and the second painter takes eight hours to paint a similarly-sized house. how long would it take the two painters together to paint the house?
It would take the two painters together eight hours to paint the house
Step-by-step explanation: Given that, One painter can paint the entire house in twelve hours. The second painter takes eight hours to paint a similarly-sized house. To find, How long would it take the two painters together to paint the house? Suppose one painter takes x hours to paint the house.
Therefore, the other painter will take x-4 hours to paint the same house. According to the question, \(1/x+1/(x-4)=1/12+1/8\) Multiply by LCM, \(8(x-4)=12x+12(x-4)8x-32=6x+484x=80x=20\)Therefore, the first painter will take 20 hours to paint the house. The second painter will take 16 hours (20-4). Together they will take, \(1/20+1/16=0.1+0.0625=0.1625\) Thus, they will take 6.1538 hours which can be rounded to 4.8 hours.

In Exercises 7-12, describe all solutions of Ax = 0 in parametric vector form, where A is row equivalent to the given matrix.
The parametric form can be written as -
\(x = x_2 \left[ \begin{array}{c} -3 \\ 1 \\ 0 \\ 0 \\ \end{array} \right] + x_3 \left[ \begin{array}{c} 0 \\ 0 \\ 1 \\ 0 \\ \end{array} \right] + x_4 \left[ \begin{array}{c} 4 \\ 0 \\ 0 \\ 1 \\ \end{array} \right]\)
What are homogeneous and non - homogeneous matrix form?A matrix equation of the form \($A\overrightarrow x=0\) is called homogeneous matrix equation.
A matrix equation of the form \($A\overrightarrow x=\overrightarrow b\) is called non - homogeneous matrix equation.
Given is to find the solution in parametric vector form.
If there are {m} free variables in the homogeneous equation, the solution set can be expressed as the span of {m} vectors :
\($\overrightarrow x=s_{1} \overrightarrow v_{1} + s_{2} \overrightarrow v_{2}+......+s_{m} \overrightarrow v_{m}\)
We have a matrix where {A} is the row equivalent to that matrix -
\(\begin{bmatrix} 1&3&0&-4 \\ 2&6&0&-8 \end{bmatrix}\)
Given matrix can be written in Augmented form as -
\(\left[ \begin{array}{cccc|c} 1&3&0&-4 & 0\\2&6&0&-8&0\\ \end{array} \right]\)
Row Reduced Echelon Form can be obtained using the following steps -
{ 1 } - Interchanging the rows R{1} and R{2}.
\(\left[ \begin{array}{cccc|c} 2&6&0&-8&0 \\ 1&3&0 &-4 & 0 \\ \end{array} \right]\)
{ 2 } - Applying the operation R{2} -> 2R{2} - R{1}, to make the second 0.
\(\left[ \begin{array}{cccc|c} 2&6&0&-8&0\\1&3&0&-4&0 \\ \end{array} \right] \;\;\;\;\;\;R_2 \rightarrow 2R_2 - R_1\)
\(\left[ \begin{array}{cccc|c} 2 & 6 & 0 & -8 & 0 \\ 0 & 0 & 0 & 0 & 0 \\ \end{array} \right]\)
{ 3 } - Using R{1} -> R{1}/2
\(\left[ \begin{array}{cccc|c} 2&6&0&-8&0\\0&0&0&0&0\\ \end{array} \right] \;\;R_1 \rightarrow \dfrac{1}{2} R_1\)
{ 4 } - Following equation can be deducted as
\(x_1 + 3x_2 - 4x_4 =0\)
{ 5 } - We can write the parametric form as -
\(x = x_2 \left[ \begin{array}{c} -3 \\ 1 \\ 0 \\ 0 \\ \end{array} \right] + x_3 \left[ \begin{array}{c} 0 \\ 0 \\ 1 \\ 0 \\ \end{array} \right] + x_4 \left[ \begin{array}{c} 4 \\ 0 \\ 0 \\ 1 \\ \end{array} \right]\)
Therefore, the parametric form can be written as -
\(x = x_2 \left[ \begin{array}{c} -3 \\ 1 \\ 0 \\ 0 \\ \end{array} \right] + x_3 \left[ \begin{array}{c} 0 \\ 0 \\ 1 \\ 0 \\ \end{array} \right] + x_4 \left[ \begin{array}{c} 4 \\ 0 \\ 0 \\ 1 \\ \end{array} \right]\)

If the scale of the map is given as 1: 3 000 000 and the distance measured on the map between Beitbridge and Musina is 1,3 cm. calculate (in km) the actual distance between Beitbridge and Musina. ● (3)
The actual distance between Beitbridge and Musina is 3,900,000 kilometers.
To calculate the actual distance between Beitbridge and Musina, given the scale of the map and the measured distance on the map, we can use the concept of scale.
The scale of the map is given as 1:3,000,000, which means that 1 cm on the map represents 3,000,000 cm in real life.
The measured distance on the map between Beitbridge and Musina is 1.3 cm.
To find the actual distance, we can set up a proportion using the scale:
1 cm on the map / 3,000,000 cm in real life = 1.3 cm on the map / x km in real life.
Simplifying the proportion, we have:
1 / 3,000,000 = 1.3 / x.
Cross-multiplying, we get:
x = (1.3 * 3,000,000) / 1.
x = 3,900,000 / 1.
x = 3,900,000 km.
The actual distance between Beitbridge and Musina is 3,900,000 kilometers.

Include a check for convergence at the endpoints of the interval.
f(x)=[infinity]∑n=0(−x3)n
The series f(x), f′(x), f′(x), and ∫f(x) dx all converge for the entire real number line, -∞ < x < ∞, including the endpoints.
The intervals of convergence are as follows: (a) f(x) converges for -∞ < x < ∞.
(b) f′(x) converges for -∞ < x < ∞.
(c) f′(x) converges for -∞ < x < ∞.
(d) ∫f(x) dx converges for -∞ < x < ∞.
The given series f(x) can be written as the sum of the terms (-x^3)^n. We need to find the intervals of x for which this series converges.
For any value of x, when (-x^3)^n is raised to a positive power n, it becomes positive. Therefore, the series will converge for any x value.
Hence, the intervals of convergence for f(x), f′(x), f′(x), and ∫f(x) dx are -∞ < x < ∞. To check for convergence at the endpoints of the interval, we need to evaluate the series for x = ±∞.
For both cases, the terms (-x^3)^n will approach zero as n approaches infinity. Therefore, the series will converge at the endpoints as well.
In summary, the series f(x), f′(x), f′(x), and ∫f(x) dx all converge for the entire real number line, -∞ < x < ∞, including the endpoints.

Answer:
(6.25\(\pi\) + 25)cm is the exact answer
44.625 cm is an approximation
Step-by-step explanation:
c = circumference (perimeter)
d = diameter
C = \(\frac{\pi d}{4}\)
C = \(\frac{25\pi }{4}\) = 6.25\(\pi\) This is the exact answer
That would be the curved part of the pi. Then we need to add the 2 sides which would be \(\frac{25}{2}\) + \(\frac{25}{2}\) = \(\frac{50}{2}\) = 25 The sides are the length of the radius which is half of the diameter.
(6.25\(\pi\) + 25)cm is the exact answer

Declared a 3-for-1 stock split.
The current price of the stock is $12 per share.
a. Calculate the current number of shares and the market value of your investment.
current number of shares
market value
b) the current number of shares is 1440, and the market value of your investment is $17,280.
To calculate the current number of shares and the market value of your investment, we need to take into account the stock splits and stock dividends.
Given:
Initial investment: $1,000
Initial number of shares: 200
Current price per share: $12
a. Calculate the current number of shares:
First, let's consider the stock splits and stock dividends:
1. 2-for-1 stock split:
This means that for each existing share, you now have two shares. So the number of shares is doubled.
New number of shares = Initial number of shares * 2 = 200 * 2 = 400 shares.
2. 20% stock dividend:
A 20% stock dividend means you receive an additional 20% of your current number of shares. To calculate the number of shares received:
Shares received = Current number of shares * (20% / 100%)
Shares received = 400 * (20 / 100) = 80 shares.
Total number of shares after the dividend = Current number of shares + Shares received = 400 + 80 = 480 shares.
3. 3-for-1 stock split:
This means that for each existing share, you now have three shares. So the number of shares is tripled.
New number of shares = Total number of shares after the dividend * 3 = 480 * 3 = 1440 shares.
The current number of shares you have is 1440.
b. Calculate the market value of your investment:
Market value = Current number of shares * Current price per share
Market value = 1440 * $12 = $17,280
