The other three faces are repeats of the three mentioned. What is the total surface area of this rectangular prism in square inches? Enter your answer in the box. in.2 Submit Answer
The total surface area of the rectangular prism is 144 square inches.
To find the total surface area of the rectangular prism, we need to find the area of all six faces and then add them together. We are given the dimensions of three of the rectangular faces, and we can assume that the other three faces have the same dimensions as the ones given.
The area of a rectangular face can be found by multiplying the length and width. Using the dimensions given in the net, we can find the area of each face:
The top and bottom faces both have dimensions of 8 inches by 3 inches, so their areas are:
A = 8 x 3 = 24 square inches (each)
The left and right faces both have dimensions of 6 inches by 4 inches, so their areas are:
A = 6 x 4 = 24 square inches (each)
The front and back faces both have dimensions of 8 inches by 6 inches, so their areas are:
A = 8 x 6 = 48 square inches (each)
To find the total surface area, we add up the areas of all six faces:
Total surface area = 2(24) + 2(48) + 2(24) = 144 square inches
Therefore, the total surface area of the rectangular prism is 144 square inches.

joe bought a new truck for $45,000. the truck depreciates at a rate of 15% per year. what will be the value of the truck in four years
Step-by-step explanation:
Each year the truck retains 85 % of its value ( 85% + 15% = 100%)
45000 * .85 * .85 * .85 * .85 = $ 45 000 * .85^4 = $ 23490.28
Answer:
The value of the truck would be $23,490.28 after 4 years.
Step-by-step explanation:
Main concepts:
Concept 1. Percentages
Concept 2. Depreciation
Concept 3. Distributive property
Concept 4. Repeated multiplication as a power
Concept 1. Percentages
A percentage is effectively a unit. In the same way that 25¢ is the same as 0.25 US dollars, 15% is the same as 0.15 (unit-less number).
A common task is to find a percentage of a quantity. For example, finding 25% of 40. Mathematically, the word "of" here means multiply, so 25% of 40 means "25% * 40". But, since a percentage can be converted to a regular unit-less number, this is also the same as "0.25 * 40" which is 10. So, 25% of 40 is 10.
Concept 2. Depreciation
To depreciate means that the value of the thing decreases. In this question, the value of the truck depreciates by 15% (per year), so its value would decrease by whatever 15% of its current value is.
15% of $45,000 is 0.15 * $45,000 = $6,750 (this is the amount that the value decreases by during the first year)
To find the value after 1 year, we need to subtract this from the original value. We'll label this equation 1:
Equation 1: $45,000 - $6,750 = $38,250Common mistake: It is a common mistake for people to continue subtracting $6,750 for years 2, 3, and 4 thinking that this is subtracting another 15%. However, each year, the 15% depreciation is based on the new value of the truck, so during the second year, the truck started at a value of $38,250 (from the end of the first year), and 15% of $38,250 will be different from 15% of $45,000.
15% of $38,250 is 0.15 * $38,250 = $5,737.50 (this is the amount that the value decreases by)
To find the value after 2 year, we need to subtract this from the value at the end of year 1. We'll label this equation 2:
Equation 2: $38,250 - $5,737.50 = $32,512.50Concept 3. Distributive property
In Equation 1 above, the left side of the equation can be factored by using the distributive property in reverse, and factoring out "$45,000":
$45,000 - $6,750 is the same as
$45,000 * ( 1 - 0.15 ) = $38,250 -- Equation 1a
This expression illuminates what is happening to the value if we change the numbers inside the parentheses into percentages
$45,000 * ( 100% - 15% )
Notice that in the parentheses, we start with 100% (whatever 100% is), and we're subtracting 15%.
Similarly, in Equation 2, the left side of the equation can be factored by using the distributive property in reverse, and factoring out "$38,250":
$38,250 - $5,737.50 is the same as
$38,250 * ( 1 - 0.15 ) = $32,512.50 -- Equation 2a
Notice that in the parentheses, we again start with 100% (whatever 100% is), and we're subtracting 15%.
Concept 4. Repeated multiplication as a power
Quick recap from Equation 1a & Equation 2a:
For year 1, Equation 1a: $45,000 * ( 1 - 0.15 ) = $38,250
For year 2, Equation 2a: $38,250 * ( 1 - 0.15 ) = $32,512.50
However, note the equivalence in bold above. This means that we can replace the $38,250 in the "Year 2" equation with the entire left side of the equation from Year 1.
Thus, for Year 2, the equation become:
$45,000 * ( 1 - 0.15 ) * ( 1 - 0.15 ) = $32,512.50
While the value at the end of year 3 could be written
$32,512.50 * ( 1 - 0.15 )
notice that the left side again starts with the value that ended the year before. With another substitution, for Year 3, the equation becomes:
$45,000 * ( 1 - 0.15 ) * ( 1 - 0.15 ) * ( 1 - 0.15 ) = Value at end of year 3
Continuing the pattern, we need the value at the end of the year before, times ( 1 - 0.15 ) to get the value for the end of the following year.
$45,000 * ( 1 - 0.15 ) * ( 1 - 0.15 ) * ( 1 - 0.15 ) * ( 1 - 0.15 ) = Value at end of year 4.
Notice that each year, we're multiplying by another factor of ( 1 - 0.15 )
Recall that multiplying by the same number or expression repeatedly can be simplified with an exponent. For example, five 2s multiplied together: 2*2*2*2*2 can be written as [tex]2^5[/tex].
Therefore, the value of the truck at the end of year 2 can be written as
[tex]\$45,000 * (1-0.15)^{2}[/tex]
The value of the truck at the end of year 3: [tex]\$45,000 * (1-0.15)^{3}[/tex]
The value of the truck at the end of year 4: [tex]\$45,000 * (1-0.15)^{4}[/tex]
Side note: the value of the truck at the end of any year "n" is [tex]\$45,000 * (1-0.15)^{n}[/tex]
So, to answer the question, and find the value of the truck in 4 years, we just need to evaluate [tex]\$45,000 * (1-0.15)^{4}[/tex]
[tex]\$45,000 * (1-0.15)^{4}=[/tex]
[tex]=\$45,000 * (0.85)^{4}[/tex]
[tex]=\$45,000 * 0.52200625[/tex]
[tex]=\$23,490.28125[/tex]
Rounded to the nearest penny, the value of the truck would be $23,490.28 after 4 years.

This prompt is about the a word problem involving an exponential function given as B(x) = 5 * 2²
What are the results of the required analysis?a) The completed table is attached. See related comments there as well.
b) Graph is attached.
c) It can be observed that this particular scenario exemplifies an exponential function, as the population of bacteria dwelling in Albert's body increases twofold every hour. Such a phenomenon indicates that the rate of growth is directly proportional to the current amount.
d) The function is given as: B(x) = 5 * 2²
e) Albert will become symptomatic when the amount of bacteria in his body reaches 1280. This will happen after 8 hours.
we can also solve this without using logarithms by repeatedly multiplying 256 by 1/2 until we get to 1, and counting the number of times we multiplied:
256 x (1/2) = 128
128 x (1/2) = 64
64 x (1/2) = 32
32 x (1/2) = 16
16 x (1/2) = 8
8 x (1/2) = 4
4 x (1/2) = 2
2 x (1/2) = 1
We multiplied 256 by 1/2 a total of 8 times , so we know that
2⁸ = 256.
Therefore, we can write: 2ˣ = 256 as 2ˣ = 2⁸
Equating the exponents on both sides, we get:
x = 8
f) B(3) = 5 x 2³
B(3) = 5 x 8
B(3) = 40
Meaning: The above means that after 3 hours, the bacterial inAlbert's body will have reached 40. This is 8 times the initial amount.
G) To find B(5.5)
We place x with 5.5 in the above function
Thus, B(5.5) = 5 x 2^5.5
= 88.39
This means that after 5.5 hours, albert will have a bout 88.39 bacterial in his body.
H) This will take 9.97 hours
We need to find the value of x in the equation:
B(x) = 5 * 2^x = 5000
Dividing both sides by 5, we get:
2^x = 1000
Taking the logarithm of both sides to base 2, we get:
log2(2^x) = log2 (1000 )
Using the property that log2(a^b) = b x log2 (a), we can simplify the left-hand side:
x * log2(2) = log2 (1000 )
Since log 2(2) = 1, we can simplify further to:
x = log 2(1000)
Using a calculator, we can evaluate this expression:
x ≈ 9.97

She can sell zucchini bread for $4 and banana bread for $3. What is the greatest amount of money Hayley can collect by selling the bread made with 22 cups of sugar and 4 sticks of butter?
Therefore, the greatest amount of money Hayley can collect by selling the bread made with 22 cups of sugar and 4 sticks of butter is $154.
What is equation?In mathematics, an equation is a statement of equality between two expressions, which are composed of variables, numbers, and mathematical operations. An equation typically has one or more variables that can take different values, and the goal is often to find the values of the variables that make the equation true. Equations can be used to model a wide range of real-world situations, from simple problems like calculating the area of a rectangle, to complex systems like those found in physics and engineering. Solving equations is a fundamental skill in mathematics, and there are many techniques and strategies for finding solutions to different types of equations.
Here,
To find the maximum amount of money Hayley can collect by selling bread, we need to find the maximum number of loaves of each type of bread she can make with 22 cups of sugar and 4 sticks of butter.
Let's assume Hayley needs x cups of sugar and y sticks of butter to make one loaf of zucchini bread, and a cups of sugar and b sticks of butter to make one loaf of banana bread. We have the following system of equations:
x + a = 22 (total cups of sugar)
y + b = 4 (total sticks of butter)
To maximize the amount of money Hayley can collect, she should make as many loaves of zucchini bread as possible, since it sells for a higher price. Therefore, we want to maximize the value of x.
Solving the system of equations, we get:
x = 22 - a
y = 4 - b
To maximize x, we want to minimize a. Let's assume a = 0 (i.e., Hayley uses all 22 cups of sugar for zucchini bread), then we get:
x = 22
y = 4 - b
To make one loaf of banana bread, Hayley needs b sticks of butter. Since b is a positive integer, the maximum value of y is 3 (when b = 1). Therefore, Hayley can make 3 loaves of banana bread and 22 loaves of zucchini bread.
The total amount of money Hayley can collect is:
3($3) + 22($4) = $66 + $88

On a given day, the flow rate F (cars per hour) on a congested roadway is
F= 3600v/(22+0.07v^2)
where v is the speed of the traffic in miles per hour. What speed will maximize the flow rate on the road?
Answer:
about 17.7 mph
Step-by-step explanation:
You want the value of v that maximizes F(v) = 3600v/(22+0.07v²).
DerivativeThe derivative of F is ...
[tex]F'(v)=\dfrac{3600(22+0.07v^2)-3600v(0.14v)}{(22+0.07v^2)^2}[/tex]
MaximumThe derivative is zero at the maximum. This is the case when the numerator is zero:
3600(22 +.07v² -.14v²) = 0
.07v² = 22
v = √(22/0.07) ≈ 17.728
Flow rate is maximized at a speed of about 17.7 miles per hour.
Vogel and Mazibuko are in a mining partnership with a profit-sharing ratio of 1:3 respectively. A new partnership was formed by admitting Malikane. A 1/6 share in the profits/loss of the new partnership was obtained by Malikane. Vogel and Mazibuko agreed to relinquish the 1/6 share according to their previous profit-sharing ratio of 1:3. The new profit-sharing ratio is:
The new profit-sharing ratio is as follows:
Mazibuko's share: Vogel's share = 5: 8
To solve this problem
Let's begin by determining the share of profits that each member of the original partnership—Vogel and Mazibuko—receives :
Vogel's share 1/(1+3) = 1/4
Share of Mazibuko: 3/(1+3) = 3/4
Let's now evaluate the new alliance with Malikane. The remaining 5/6 of the profits are divided between Vogel and Mazibuko in accordance with their prior profit-sharing ratio because Malikane receives a 1/6 part of the profits.
As a result, Vogel and Mazibuko share in the following profits from the new partnership:
Share for Vogel: (1/4) * (5/6) = 5/24
Share for Mazibuko: (3/4) * (5/6) = 15/24 = 5/8
The new profit-sharing ratio is as follows:
Mazibuko's share: Vogel's share = 5: 8
So, Vogel obtains 5 of the profits from the new partnership's 13 shares, whereas Mazibuko receives 8 of the income from the 13 shares.

PLEASE HELP! Mr. Smith makes $20 an hour working full time. He gets about 25% of his income taken out for taxes. He came up with the following monthly budget.
Household:
Rent: $700
Cable: $85
Cell Phone: $175
Electric: $100
Food: $350
Total: 1,410
Automobile
Car: $200
Car Insurance: $100
Gas: $90
Maintenance: $15
Total: $405
How much money does he have left over monthly to put into savings?
Answer:
$585/month
Step-by-step explanation:
To determine how much money Mr. Smith has left over monthly to put into savings, we need to first calculate his monthly income and his monthly expenses, including taxes.
Mr. Smith's hourly rate is $20, and he works full time, which is typically 40 hours per week. Therefore, his weekly income is:
$20/hour x 40 hours/week = $800/week
To find his monthly income, we multiply his weekly income by the number of weeks in a month:
$800/week x 4 weeks/month = $3,200/month
To find his monthly expenses, we add up the amounts for his household and automobile expenses:
$1,410/month (household) + $405/month (automobile) = $1,815/month
Since Mr. Smith gets about 25% of his income taken out for taxes, we need to calculate the amount of taxes he pays each month:
$3,200/month x 0.25 = $800/month (taxes)
Now we can subtract his monthly expenses and taxes from his monthly income to find out how much money he has left over to put into savings:
$3,200/month - $1,815/month - $800/month = $585/month
Therefore, Mr. Smith has $585/month left over to put into savings after paying his expenses and taxes.

The volume of the regular box is LWH, and the volume of the family value box is
(1.25L)(W)(1.15H) = 1.4375LWH.
To find the percentage increase in volume from the regular box to the family value box, we can use the following formula:
Percentage increase = (New value - Old value) ÷ Old value x 100%
In this case, the old value is the volume of the regular box, and the new value is the volume of the family value box. Therefore, the percentage increase in volume is:
(1.4375LWH - LWH) ÷ LWH x 100% ≈ 44%

b) The completed construction of a regular hexagon is shown below. Explain why AACF is a 30°-
60°-90° triangle. (10 points)
ACF is a 30º-60º-90º triangle because of the following:
1) Based on a theorem, in a 30°-60°-90° triangle the sides are in the ratio 1 : 2 : [tex]\sqrt{3}[/tex]
1 → short leg
2 → hypotenuse
[tex]\sqrt{3}[/tex] → long leg
Side length of the hexagon is the short leg of the triangle. It is 1.
r1 is the radius of the incircle in a regular hexagon. 2(r1) is the diameter of the incircle. It is also the hypotenuse of the right triangle. It is 2.
Using Pythagorean theorem.
[tex]a^2 + b^2 = c^2[/tex]
[tex]1^2 + b^2 = 2^2[/tex]
[tex]b^2 = 2^2 - 1^2[/tex]
[tex]b^2 = 4 - 1[/tex]
[tex]b^2 = 3[/tex]
[tex]\sqrt{b^2} = \sqrt{3}[/tex]

7. Which of these graphs are connected?
In the given graphs, the first and third graphs are connected graphs.
What are connected graphs:A connected graph is a collection of vertices, or points, and edges, or lines, such that there is a path between every pair of vertices.
This means that it is not possible to find any isolated vertices or disjoint subsets of vertices, and every vertex is connected to at least one other vertex.
The edges of a connected graph represent the relationships or connections between the vertices.
Here we have 3 graphs
In the first graph, every vertex is connected to other vertices and we can go from one node to another node
Hence, The first graph is a connected graph
In the second graph, there are two graphs that are not connected to other. Hence, The Second graph is not a connected graph
In the third graph, every node is connected
Hence, The third graph is a connected graph.
Therefore,

2(cos(π/18) + i sin(π/18))
2(cos(7π/18) + i sin(7π/18))
2(cos(11π/18) + i sin(11π/18))
Finding Cube Roots of Complex Numbers:To find the cube roots of a complex number, you can follow these steps:
Step 1: Write the complex number in polar form.
Step 2: Use the formula for finding the cube roots of a complex number in polar form. The formula for finding the cube roots of a complex number in polar form is:
[tex]z^{\frac{1}{3}} = r^{\frac{1}{3} } [cos((\theta + 2k\pi)/3) + i sin((\theta + 2k\pi )/3)][/tex]
Step 3: Substitute the values into the formula.
Substitute the values for r and θ into the formula, and simplify.
Step 4: Calculate the cube roots.
Step 5: Write the cube roots in rectangular form.
Here we have 4√3 + 4i
The polar form of the complex number is
=> 4√3 + 4i = 8(cos(π/6) + i sin(π/6))
Using the formula, [tex]z^{\frac{1}{3}} = r^{\frac{1}{3} } [cos((\theta + 2k\pi)/3) + i sin((\theta + 2k\pi )/3)][/tex]
[tex]z^{\frac{1}{3}} = 8^{\frac{1}{3} } [cos((\pi /6 + 2k\pi)/3) + i sin((\pi/6 + 2k\pi )/3)][/tex]
where k = 0, 1, 2.
Now, we can calculate the cube roots by substituting the values of k into the formula and simplifying. Here are the three cube roots:
Substituting k = 0, 1, 2 into the formula, we get:
k = 0: [tex]z^{1/3}[/tex] = 2(cos(π/18) + i sin(π/18))
k = 1: [tex]z^{1/3}[/tex] = 2(cos(7π/18) + i sin(7π/18))
k = 2: [tex]z^{1/3}[/tex] = 2(cos(11π/18) + i sin(11π/18))

One possible rational function with the given characteristics is r(x) = 4 + (x + 9)(x + 2)(x - 4) / [(x - 3)(x + 5)].
What is the function?In general, a function is a mathematical concept that defines a relationship between an input (or set of inputs) and an output (or set of outputs). It is a rule that takes an input value and produces a corresponding output value.
According to the given information:One possible rational function with the given characteristics is:
r(x) = 4 + (x + 9)(x + 2)(x - 4) / [(x - 3)(x + 5)]
Explanation:
The factor (x + 9) in the numerator makes the function cross the x-axis at x = -9.
The factor (x - 4) in the numerator makes the function touch the x-axis at x = 4.
The factors (x - 3) and (x + 5) in the denominator create vertical asymptotes at x = 3 and x = -5, respectively.
The factor (x + 2) in the numerator creates a hole at x = -2, since it cancels out the factor (x + 2) in the denominator.
Finally, the constant term 4 in the numerator and the absence of any higher degree terms in the numerator or denominator create a horizontal asymptote at y = 4.
Note that there may be other rational functions with the same characteristics, but this is one possible solution.
Therefore, One possible rational function with the given characteristics is r(x) = 4 + (x + 9)(x + 2)(x - 4) / [(x - 3)(x + 5)].
