Answer:
Since the prism is completely filled with 96 cubes that have an edge length of 1/2 cm, we can find the volume of the prism by multiplying the number of cubes by the volume of each cube.
The volume of each cube is (1/2 cm)^3 = 1/8 cm^3.
The number of cubes is 96.
Therefore, the volume of the prism is:
volume = (number of cubes) x (volume of each cube)
volume = 96 x (1/8 cm^3)
volume = 12 cm^3
So, the volume of the prism is 12 cubic centimeters.

Measure of the arc or angle indicated is 150.9 degrees.
Describe Arc?In geometry, an arc is a portion of the circumference of a circle or any other curved shape. It is defined by two endpoints and all the points on the curve that lie between them. An arc is usually named by its two endpoints, with a small arc symbol above them to indicate that it is an arc.
The length of an arc can be calculated using the formula:
Arc length = (central angle/360) x 2πr
where r is the radius of the circle, and the central angle is the angle subtended by the arc at the center of the circle, measured in degrees.
The measure of an arc is the degree measure of the central angle subtended by the arc. A semicircle is an arc that subtends a central angle of 180 degrees, and a full circle is an arc that subtends a central angle of 360 degrees.
Since DE and PE are chords of the circle, and they intersect at point P, we can use the intersecting chords theorem to find the length of DP. Let x be the length of DP. Then:
DP * PE = DE * PC
x * (x + PE) = ([tex]\frac{CE}{2}[/tex]) * ([tex]\frac{CE}{2}[/tex])
x² + x(PE) - [tex]\frac{CE}{2}^{\frac{2}{4} }[/tex] = 0
Since angle DPE is 60 degrees, we can use the law of cosines to find PE. Let y be the length of PE. Then:
y² = DE² + DP² - 2 * DE * DP * cos(60)
y² = ([tex]\frac{CE}{2}[/tex])² + x^2 - ([tex]\frac{CE}{2}[/tex]) * x
Substitute this expression for y^2 into the equation for x and simplify:
[tex]x^{2} +x((\frac{CE}{2})^{2} + x^{2} -\frac{CE}{2} *x)^{0.5} -(\frac{CE}{2} ^{\frac{2}{4} } )=0[/tex]
Solve for x:
x = [tex]\frac{CE^{2} -4*(CE^{2} -3*\frac{CE}{2} ^{2} )^{0.5} }{4}[/tex]
x = [tex]\frac{3}{4} *\frac{CE^{2} }{CE^{2} -12}[/tex]
Now we can find the measure of the CD arc by using the formula for the central angle:
CD arc = [tex]2*arctan(\frac{DP}{CE})[/tex]
CD arc = [tex]2*arctan(\frac{x}{\frac{CE}{2} } )[/tex]
CD arc = [tex]2* arctan(CE^{2} -4*(CE^{2} -3*\frac{(\frac{CE}{2} ^{2})^{0.5}}{CE^{2}-12 } ))[/tex]
Simplifying this expression, we get:
[tex]CD arc=2*arctan(2*3^{\frac{1}{2} } -1)[/tex]
CD arc ≈ 150.9 degrees.

Measure of the arc or angle indicated in the given figure is 150.9 degrees.
Describe Arc?In geometry, an arc is a portion of the circumference of a circle or other curved shape. It is defined by his two endpoints and all midpoints of the curve. Arcs are usually named after their two endpoints, with a small arc symbol above them to indicate that they are arcs.
Arc Length = (Center Angle/360) x 2πr
where r is the radius of the circle and the central angle is the angle the arc makes at the center of the circle, measured in degrees.
The arc measurement is the angle of the central angle defined by the arc. A half circle is an arc that spans a central angle of 180 degrees, and a full circle is an arc that spans a central angle of 360 degrees.
Since DE and PE are chords of the circle and intersect at P, we can use the chord rule to find the length of DP. Let x be the length of DP. Then:
DP × PE = DE × PC
x × (x + PE) = (CE/2) × (CE/2)
x² + x(PE) - [tex]\frac{CE}{2} ^{\frac{2}{4} }[/tex] = 0
Since angle DPE is 60 degrees, we can use the law of cosines to find PE. Let y be the length of PE. Then:
y² = DE² + DP² - 2 × DE × DP × cos(60)
y² = ([tex]\frac{CE}{2}[/tex])² + x² - ([tex]\frac{CE}{2}[/tex]) × x
Substitute this expression for y² into the equation for x and simplify:
[tex]x^{2} +x((\frac{CE}{2} ^{2}) + x^{2} - \frac{CE}{2}*x)^{0.5} -[/tex] [tex]\frac{CE}{2} ^{\frac{2}{4} }[/tex] = 0
Solve for x:
x = [tex]\frac{CE^{2} - 4*(CE^{2}-3*\frac{CE}{2} ^{2})^{0.5} }{4}[/tex]
x = (3/4) × (CE²/CE²-12)
Now we can find the measure of the CD arc by using the formula for the central angle:
CD arc = 2arc tan(DP/CE)
CD arc = 2arc tan [x/(CE/2)]
CD arc = 2arc tan (CE² - 4 × (CE² - 3 × [tex]\frac{(\frac{CE}{2} ^{2}) ^{0.5} }{CE^{2}-12 }[/tex] )
Simplifying this expression, we get:

Write the polynomial in standard form. Then classify the polynomial by degree and by number of terms.
7x² +9x² - 6x²
Write the polynomial in standard form.
(Simplify your answer.)
Answer:
Step-by-step explanation:
When we combine like terms, we get:

the cost for3.8 pounds of shrimp is 18.05 . find the unit price in dollars per pound. if necessary round it to the nearest cent
The unit price in dollars per pound is $4.75 (rounded to the nearest cent).
What is profit and loss?
Mathematicians use the profit and loss formula to calculate market prices for goods and to assess how lucrative a company is. There is a selling price and a cost price for every commodity. We can determine the profit made or loss suffered for a specific commodity based on the values of these prices. Cost price, fixed, variable, and semi-variable costs, selling price, marked price, list price, margin, etc. are some of the key words that are discussed in this article.
To find the unit price in dollars per pound, we need to divide the total cost by the total weight:
Unit price = Total cost / Total weight
In this case, the total weight is 3.8 pounds and the total cost is $18.05.
Unit price = $18.05 / 3.8 pounds
Unit price = $4.75 per pound (rounded to the nearest cent)
Therefore, the unit price in dollars per pound is $4.75 (rounded to the nearest cent).

A,B and B,C form a right angle at point B. If A = (-3,-1) and B = (4,4), what is the equation of B,C?
Answer:
the equation of line BC is y = (-7/5)x + (48/5).
Step-by-step explanation:
To find the equation of the line that passes through points B and C, we first need to determine the coordinates of point C. Since the angle at B is a right angle, we can use the slope of line AB to find the slope of line BC.
The slope of line AB is:
mAB = (yB - yA) / (xB - xA)
= (4 - (-1)) / (4 - (-3))
= 5/7
Since lines AB and BC are perpendicular, the slope of line BC is the negative reciprocal of the slope of line AB:
mBC = -1 / mAB
= -7/5
Now we can use the point-slope form of the equation of a line to find the equation of line BC. We can use point B as the known point, since we already know its coordinates:
y - yB = mBC(x - xB)
Substituting the values we have:
y - 4 = (-7/5)(x - 4)
Expanding and simplifying:
y - 4 = (-7/5)x + (28/5)
y = (-7/5)x + (48/5)

The answers to both questions are as:
(a) the value of the investment after 5 years is $14,917.95, after 10 years is $23,673.58, and after 15 years is $37,337.35,
b) the amount of the final payment is $688.32.
What is compound interest?
Compound interest is when you earn interest on both the money you've saved and the interest you earn.
We can use the formula for compound interest to solve this problem:
[tex]A = P(1 + r/n)^{(nt)}[/tex]
where A is the final amount, P is the principal (initial investment), r is the annual interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the time (in years).
(a) For 5 years with semiannual compounding:
n = 2 (compounded semiannually)
r = 0.08 (8% annual rate)
t = 5
[tex]A = 9900(1 + 0.08/2)^{(2*5)}[/tex]
A = $14,917.95
(b) For 10 years with semiannual compounding:
n = 2 (compounded semiannually)
r = 0.08 (8% annual rate)
t = 10
[tex]A = 9900(1 + 0.08/2)^{(2*10)}[/tex]
A = $23,673.58
(c) For 15 years with semiannual compounding:
n = 2 (compounded semiannually)
r = 0.08 (8% annual rate)
t = 15
[tex]A = 9900(1 + 0.08/2)^{(2*15)}[/tex]
A = $37,337.35
Therefore, the value of the investment after 5 years is $14,917.95, after 10 years is $23,673.58, and after 15 years is $37,337.35, assuming the interest is compounded semiannually.
To calculate the final payment, we can first find the balance of the loan at the end of the fifth year, and then use this as the principal to calculate the balance at the end of the tenth year.
The interest rate is 5% per year, compounded quarterly. This means that the quarterly interest rate is:
r = 5% / 4 = 0.0125
Let B be the balance of the loan after 5 years. Then we have:
B = 1000*(1 + r)²⁰- 200*(1 + r)⁴
where the first term is the future value of the initial loan after 5 years, and the second term is the present value of the first payment of $200.
Plugging in the values, we get:
B = 1000*(1 + 0.0125)²⁰ - 200*(1 + 0.0125)⁴
B = 1000*(1.0125)²⁰ - 200*(1.0125)⁴
B = 1346.49
So the balance of the loan after 5 years is $1346.49. We can use this as the principal to calculate the balance at the end of the tenth year, which is the final payment we are looking for.
Let P be the final payment. Then we have:
P = 1346.49*(1 + r)⁴⁰ - 800*(1 + r)²⁰
where the first term is the future value of the balance after 10 years, and the second term is the present value of the second payment of $800.
Plugging in the values, we get:
P = 1346.49*(1 + 0.0125)⁴⁰ - 800*(1 + 0.0125)²⁰
P = 1346.49*(1.0125)⁴⁰ - 800*(1.0125)²⁰
P = 688.32
So the amount of the final payment is $688.32.
hence, the answers to both questions are as:
(a) the value of the investment after 5 years is $14,917.95, after 10 years is $23,673.58, and after 15 years is $37,337.35,
b) the amount of the final payment is $688.32.

How to determine the set that represent the three sides of a triangleThe set of numbers {7, 15, 20} could represent the three sides of a triangle, but the other sets of numbers do not satisfy the triangle inequality theorem, which states that the sum of any two sides of a triangle must be greater than the third side. Checking the sets of numbers:
For {7, 15, 20}, 7 + 15 > 20, 7 + 20 > 15, and 15 + 20 > 7, so they satisfy the triangle inequality theorem and could represent the sides of a triangle.
For {7, 16, 23}, 7 + 16 < 23, so they do not satisfy the triangle inequality theorem and cannot represent the sides of a triangle.
For {11, 22, 35}, 11 + 22 < 35, so they do not satisfy the triangle inequality theorem and cannot represent the sides of a triangle.
For {5, 17, 22}, 5 + 17 < 22, so they do not satisfy the triangle inequality theorem and cannot represent the sides of a triangle.
Therefore, the answer is {7, 15, 20}.

13. The profit, in thousands of dollars, from the sale of x kilogram of coffee bean can be modelled by the function () = 5−400 +600 . a) State the asymptotes and the intercepts. Then, sketch a graph of this function using its key features. (5 pts) b) State the domain and range in this context. (2 points) c) Explain the significance of the horizontal asymptote. (1 point) d) Algebraically, find how much amount of tuna fish, in kg, should be sold to have a profit of exactly $4000? (4 points) SOLUTION
Answer: a) The profit function can be written as:
P(x) = 5x - 400x + 600
To find the asymptotes, we can look at the denominator of the second term, which is (x - 3). This means that there is a vertical asymptote at x = 3. To find the intercepts, we can set P(x) = 0:
5x - 400x + 600 = 0
Solving for x, we get:
x = 1.5 and x = 2.5
Therefore, there are x-intercepts at (1.5, 0) and (2.5, 0). To sketch the graph, we can also note that the coefficient of x^2 is negative, which means that the graph is a downward-facing parabola.
b) The domain of the function is the set of all possible values of x, which in this context represents the amount of coffee sold. Since we cannot sell a negative amount of coffee, the domain is x ≥ 0.
The range of the function is the set of all possible values of P(x), which represents the profit. Since the coefficient of x^2 is negative, the maximum profit occurs at the vertex of the parabola. The vertex has x-coordinate:
x = -b/(2a) = -(-400)/(2(-200)) = 1
Therefore, the maximum profit occurs when x = 1. The vertex has y-coordinate:
P(1) = 5(1) - 400(1) + 600 = 205
Since the coefficient of x^2 is negative, the range is (-∞, 205].
c) The horizontal asymptote of the function is y = -400, which represents the long-term average profit per kilogram of coffee sold. This means that as x gets very large, the profit per kilogram approaches -400. This could happen, for example, if the cost of producing the coffee increased significantly while the price remained the same.
d) To find the amount of coffee that must be sold to make a profit of $4000, we can set P(x) = 4000 and solve for x:
5x - 400x + 600 = 4000
Simplifying, we get:
-395x = -3400
Dividing both sides by -395, we get:
x ≈ 8.61
Therefore, approximately 8.61 kg of coffee must be sold to make a profit of $4000.

Therefore, the probability that at least one of the next six births is a girl is 1 - 0.033 = 0.967 (rounded to three decimal places).
What is Probability?Probability is a measure of the likelihood that an event will occur. It is a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that the event is certain.
To calculate the probability of an event, you divide the number of ways that event can occur by the total number of possible outcomes. For example, if you flip a fair coin, there are two possible outcomes - heads or tails - and each has an equal probability of 0.5 (or 50%) of occurring.
Given by the question.
To find the probability that at least one of the next six births is a girl, we can find the probability that all six of them are boys and subtract it from 1.
The probability that one birth is a girl is 1 - 0.513 = 0.487.
The probability that all six births are boys is. [tex]0.513^{6}[/tex] = 0.033.
