The volume and total surface area of each shape combined is calculated below.
How to find the volume and total surface area of each shape combined?For cone-hemisphere shape
Volume = volume of cone + volume of hemisphere
Volume = 1/3πr²h + 2/3πr³
where r = 9/2 = 4.5 m
h = √(13² - 4.5²) (Pythagoras)
h = 12.20 m
Volume = 1/3πr²h + 2/3πr³
Volume = (1/3 * 3.14 * 4.5² * 12.2) + (2/3 * 3.14 * 4.5³)
Volume = 449.33 m³
Surface area = curved surface area of cone + curved surface area of hemisphere
Surface area = πrl + 2πr², where l = 13 m
Surface area = (3.14 * 4.5 * 13) + (2 * 3.14 * 4.5²)
Surface area = 310.86 cm²
For hemisphere-cylinder shape
Volume = volume of hemisphere + volume of cylinder
Volume = 2/3πr³ + πr²h
where r = 22/2 = 11 ft
height of cylinder (h) = 45 - 11 = 34 ft
Volume = (2/3 * 3.14 * 11³) + (3.14 * 11² * 34)
Volume = 15704.19 ft³
Surface area = curved surface area of hemisphere + curved surface area of cylinder + curved surface area circular base of cylinder
Surface area = 2πr² + πr² + 2πrh
Surface area = 3πr² + 2πrh
Surface area = (3 * 3.14 * 11²) + (2 * 3.14 * 11 * 34)
Surface area = 3488.54 ft²

Answer:
Step-by-step explanation:
Question 1 :
The statement that best describes the solutions of a two-variable equation is (1) The ordered pairs must lie on the graphed equation. This means that any ordered pair (x,y) that satisfies the equation will corresponds to a point on the graph of the equation. In other words, if we plot all the points (x,y) that make the equation true, we will obtain the graph of the equation. Any points that do not lie on the graph is not a solution to the equation. Therefore, when solving a two-variable equation, we need to find the values of x and y that make the equation true and plot those points on the graph to visualize the solutions.
Question 2 :
To use the arithmetic sequence formula, we need to know the first term (a1), the common difference (d), and the desired term (an). In this case, we are given the first term as 4 and the common difference as 3 (since each term is increasing by 3). To find the 10th term, we would replace the variable "n" with 10 in the formula. Therefore, to determine the 10th term of this sequence, we would use the formula:
a10 = a1 + (n-1)d
a10 = 4 + (10-1)*3
a10 = 4 + 27
a10 = 31
Thus, the 10th term of the given sequence is 31.
Question 3 :
The formula an = al + (n-1)d is used to determine the nth term in an arithmetic sequence, where "a" represents the first term in the sequence, "n" represents the term number being solved for, and "d" is the common difference between terms. The formula essentially states that to find any term in an arithmetic sequence, one must add the common difference between terms multiplied by the number of terms-1 to the value of the first term. This formula can be applied to various situations, such as determining the total cost of goods sold in a business with a constant markup percentage, or calculating the number of days it will take to save a given amount of money with a fixed monthly contribution. By understanding the principles behind the formula, individuals can successfully solve problems involving arithmetic sequences in a variety of contexts.
What is the volume of a rectangle prism with a length of 24 1/2 feet a width of 14 feet and a height of 11 feet
Answers
Answer:
19,322 cubic feet.
Step-by-step explanation:
Volume = Length × Width × Height
Given the measurements provided:
Length = 24 1/2 feet
Width = 14 feet
Height = 11 feet
We need to convert the mixed number for the length, 24 1/2 feet, into a single fraction.
24 1/2 feet = 24 + 1/2 feet = 48/2 + 1/2 feet = 49/2 feet
Now we can substitute the given values into the formula for volume:
Volume = (Length) × (Width) × (Height)
= (49/2 feet) × (14 feet) × (11 feet)
Next, we can multiply the lengths, widths, and heights together:
Volume = (49/2 feet) × (14 feet) × (11 feet)
= 49 × 14 × 11 cubic feet / 2
Finally, we can calculate the volume by dividing the product by 2:
Volume = 49 × 14 × 11 cubic feet / 2
= 19,322 cubic feet

From the given information about the vertices of the quadrilateral, the point at which the PQRS quadrilateral will be made a rectangle is S(17/14, -1/7).
What is a quadrilateral? What are its properties?A quadrilateral is a four-sided polygon, which means it's an unrestricted shape with four straight sides.The parcels of a quadrilateral include Four sides A quadrilateral has four sides.The sum of the angles in a quadrilateral is always 360 degrees.Each type of quadrilateral has its own unique set of parcels and characteristics.Perimeter The border of a quadrilateral is the sum of the lengths of its sides.Area The area of a quadrilateral can be calculated using colorful formulas, depending on the type of quadrilateral and the information given about its sides and angles.What is a rectangle? What are its properties?An example of a quadrilateral with all four angles at right angles (90 degrees) and opposite sides that are parallel and of equal length is a rectangle.The characteristics of a rectangle are as follows: 4 right angles: A rectangle has four angles, and all four of them are right angles, which means they are all 90 degrees.A rectangle's perimeter is determined by adding the lengths of its four sides, which is equal to twice the length plus twice the width.Area: The length times the breadth of a rectangle equals the area of that shape.Perpendicular sides are opposite sides: A rectangle's opposite sides are perpendicular to one another, therefore when they intersect, they do so at a right angle.Parallelograms include rectangles as well: since a rectangleWe need to find the point that would make PQRS a rectangle. We will first determine the fourth vertex S which, when connected to the remaining three vertices, forms a quadrilateral with four right angles.As opposite sides of a rectangle are parallel and equal in length, we can first find the lengths of PQ and RS, which should be equal in a rectangle.From the distance formula, we have:PQ = [tex]\sqrt{6-7)^{2}} +(-3+5)^{2} =\sqrt{[2^{2}+(-2)^{2} } =\sqrt{8}[/tex]RS = [tex]\sqrt{(0 - 6)^2+ (-5 + 3)^2} + \sqrt{[(-6)^2 + (-2)^2] }= \sqrt40}[/tex]The midpoint of PQ is: [tex][(6 - 5)/2, (-3 - 3)/2] = (0, -3)[/tex]The slope of PQ is: [tex](6 - 7)/(-3 + 5) = -1/2[/tex]The equation of the perpendicular bisector of PQ is:[tex]y + 3 = 2(x - 0) or y = 2x - 3[/tex]The midpoint of RS is: [tex][(0 - 6)/2, (-5 - 0)/2] = (-3, -5/2)[/tex]The slope of RS is: [tex](0 - 6)/(-5 + 3) = 3[/tex]The equation of the perpendicular bisector of RS is :[tex]y + 5/2 = (-1/3)(x + 3) or y = (-1/3)x - 1/6[/tex]Now to find the intersection of these two lines, we can set them equal to each other and compute the value for x:[tex]2x - 3 = (-1/3)x - 1/6[/tex][tex]12x - 18 = -2x - 1[/tex]Adding 2x and 18 to both sides gives:[tex]14x = 17x = 17/14[/tex]To find the y-coordinate of the intersection, substitute x into either equation:[tex]y = 2(17/14) - 3 = 1/7[/tex]So, the point that would make PQRS a rectangle is S(17/14, -1/7).To know more about polygons visit:

The answer is option c.) S(-8,2).
What is quadrilateral?A closed quadrilateral has four sides, four vertices, and four angles. It is a form of polygon. In order to create it, four non-collinear points are joined. Quadrilaterals always have a total internal angle of 360 degrees.
For PQRS to be a rectangle, its opposite sides must be parallel and have equal length. We can find the length of PQ and RS using the distance formula:
PQ = √[(Qx - Px)² + (Qy - Py)²]
= √[(-3 - (-5))² + (6 - 7)²]
= √[4 + 1]
= √[5]
RS = √[(Sx - Rx)² + (Sy - Ry)²]
= √[(-8 - (-6))² + (2 - 0)²]
= √[4 + 4]
= √[8]
Since PQ and RS are not equal, we need to find a point S such that PQRS has equal sides. Moreover, the diagonals of a rectangle bisect each other. Hence, we can use the midpoint formula to find a point that bisects PR:
M = [(-5 - 6)/2, (7 + 0)/2]
= (-11/2, 7/2)
Let's consider each option:
a.) S(-4,-1)
The slope of PQ is (6 - 7)/(-3 + 5) = -1/2, so the slope of RS must be -1/2 as well. The slope of RS is (2 - 0)/(-8 + 6) = 1, so S(-4, -1) cannot be a point of RS.
b.) S(-7,2)
The slope of PQ is (6 - 7)/(-3 + 5) = -1/2, so the slope of RS must be -1/2 as well. The slope of RS is (2 - 0)/(-7 + 6) = -2, so S(-7, 2) cannot be a point of RS.
c.) S(-8,2)
The slope of PQ is (6 - 7)/(-3 + 5) = -1/2, so the slope of RS must be -1/2 as well. The slope of RS is (2 - 0)/(-8 + 6) = 1, so S(-8, 2) could be a point of RS. Moreover, the distance from S to the midpoint of PR is:
√[(-11/2 - (-8))² + (7/2 - 2)²]
= √[25/4 + 9/4]
= √[34]/2
This is equal to the length of PQ, so PQRS could be a rectangle with S(-8, 2).
d.) S(-8,1)
The slope of PQ is (6 - 7)/(-3 + 5) = -1/2, so the slope of RS must be -1/2 as well. The slope of RS is (1 - 0)/(-8 + 6) = -1, so S(-8, 1) cannot be a point of RS.
Therefore, the answer is option c.) S(-8,2).

in a hypothetical study, a pharmaceutical company is interested in finding the dosage of a new medication that best treats panic attacks. ninety people, who are diagnosed with panic attacks, were randomly assigned to three groups: (1) 20 milligrams of the new drug, (2) 30 milligrams of the new drug, and (3) 40 milligrams of the new drug. after 30 days on the medication, each participant records the number of panic attacks they have experienced in the previous seven days. what hypothesis testing technique should the researcher use to analyze the data?
Answers
In this scenario, the researcher is interested in comparing the effectiveness of three different doses of a new medication in treating panic attacks. To analyze the data, the researcher can use a hypothesis testing technique called analysis of variance (ANOVA).
ANOVA is a statistical technique used to compare the means of three or more groups to determine if there are significant differences between them. In this case, the means being compared are the number of panic attacks experienced by each group after 30 days on the medication.
The null hypothesis in this study would be that there is no significant difference in the mean number of panic attacks between the three dosage groups, and the alternative hypothesis would be that there is a significant difference in the mean number of panic attacks between at least two of the dosage groups.
The researcher can use a one-way ANOVA test to analyze the data, which will calculate the F-statistic and associated p-value. If the p-value is less than the chosen significance level (usually 0.05), the researcher can reject the null hypothesis and conclude that there is a significant difference in the mean number of panic attacks between at least two of the dosage groups.
If a significant difference is found, post-hoc tests such as Tukey's HSD can be used to determine which specific groups have significantly different means.

what is different about P3(x)=x^4-21x+20x? what interceps would you predict for its graph?
Answers
There seems to be an error in the expression for P3(x). It appears to be missing an exponent for the second term.
Assuming that the correct expression is P3(x) = x^4 - 21x^2 + 20x, we can analyze its properties.
The degree of the polynomial P3(x) is 4, which means its graph will have at most 4 x-intercepts and at most 3 turning points.
To find the x-intercepts, we set P3(x) equal to zero and solve for x:
x^4 - 21x^2 + 20x = 0
x(x^3 - 21x + 20) = 0
Using the factor theorem or synthetic division, we can find that x = 0 is a root of the polynomial, so (x-0) is a factor. The remaining cubic factor can be factored as (x-1)(x-4)(x+5).
Therefore, the x-intercepts of the graph of P3(x) are x = 0, x = 1, x = 4, and x = -5.
What intercepts would you predict for its graph?As for the y-intercept, we can find it by setting x = 0:
P3(0) = 0^4 - 21(0)^2 + 20(0) = 0
So the y-intercept is (0,0).
To determine the turning points, we can find the critical points by taking the derivative of P3(x) and setting it equal to zero:
P3'(x) = 4x^3 - 42x + 20
4x^3 - 42x + 20 = 0
Solving this equation yields three critical points: x ≈ -1.23, x ≈ 0.58, and x ≈ 2.65.
We can use the second derivative test to determine the nature of these critical points. The second derivative is:
P3''(x) = 12x^2 - 42
At x ≈ -1.23 and x ≈ 2.65, the second derivative is negative, indicating that these are local maxima. At x ≈ 0.58, the second derivative is positive, indicating that this is a local minimum.
Therefore, the graph of P3(x) has a local maximum at (approximately) (-1.23, P3(-1.23)), a local minimum at (approximately) (0.58, P3(0.58)), and a local maximum at (approximately) (2.65, P3(2.65)).

Answers
The standard form of the polynomial 2m-3m²+4m⁵+21 is 4m⁵ - 3m² + 2m + 21.
The standard form of a polynomial is when the polynomial is written with the terms in descending order of degree, with each term having a coefficient and an exponent. To convert the given polynomial 2m-3m²+4m⁵+21 to standard form, we need to rearrange the terms in descending order of degree.
The degree of a term is the exponent of the variable in that term. For example, the degree of the term 4m⁵ is 5, and the degree of the term -3m² is 2.
So, we start by arranging the terms in descending order of degree:
4m⁵ - 3m² + 2m + 21
Next, we can simplify the coefficients of each term if possible. In this case, all of the coefficients are already simplified, so we leave them as they are.
In summary, to convert a polynomial to standard form, we arrange the terms in descending order of degree and simplify the coefficients of each term if possible. This makes it easier to compare and manipulate polynomials, and is often required when solving equations or finding roots of polynomials.

in one day a 20 pound dog eats 3 cups of food. How much would a 50 pound dog eat
Answers
Let x be the amount of food (in cups) that a 50 pound dog eats in one day.
Since the amount of food eaten is directly proportional to the weight of the dog, we can set up the following proportion:
20 pounds / 3 cups = 50 pounds / x cups
To solve for x, we can cross-multiply:
20 pounds * x cups = 3 cups * 50 pounds
20x = 150
x = 7.5
Therefore, a 50 pound dog would eat approximately 7.5 cups of food in one day, assuming that the amount of food eaten is directly proportional to the weight of the dog.

simple interest per year. After 3
years, what is the earned
interest?
Answers
the earned interest after 3 years is $1,608.75.
What is simple interest?
Before delving further into the concept of simple interest, it is worth noting that it is a straightforward method for calculating interest on money, whereby interest is added at a constant rate for each time period and always to the initial principal amount. When we deposit our money into a bank, we can earn interest on our investment. Simple interest is one type of interest that banks may offer.
The formula for simple interest is:
I = P * r * t
where:
I = interest earned
P = principal (initial amount)
r = interest rate per year (as a decimal)
t = time (in years)
Substituting the given values, we have:
P = $9,750
r = 0.055 (since the interest rate is 5.5%)
t = 3
I = $9,750 * 0.055 * 3
I = $1,608.75
Therefore, the earned interest after 3 years is $1,608.75.

True. System developers can initiate a formal project as early as the preliminary investigation stage or later on as
analysis, design, and implementation activities occur.
The initiation stage is when the need for a new system is identified, and preliminary investigations are conducted to
determine the feasibility of the project.
If the project is deemed feasible, the formal project can be initiated at this stage.
However, if the project is initiated later on, the analysis, design, and implementation activities will have already begun.

find the lemgth of arc PQ
Answers
The arc length is D) 3.14 meters.
What is arc length?
In mathematics, an arc is a portion of a curve that can be thought of as a segment of the curve. An arc is a connected set of points on a curve, usually a portion of a circle.
It is defined by two endpoints and all the points along the curve between them. The length of an arc is the distance along the curve between its two endpoints.
The distance along the curved line that forms the arc (a section of a circle) is measured using the arc length formula.
[tex]A_L=\frac{\theta}{360\textdegree}2\pi r[/tex]
Here the give circle Radius PR = 3m and θ=60°.
Now using arc length formula then,
=> Arc length [tex]A_L=\frac{\theta}{360\textdegree}2\pi r[/tex]
=> [tex]A_L=\frac{60}{360} \times2\times3.14\times3[/tex]
=> [tex]A_L=\frac{1}{6}\times2\times3.14\times3[/tex]
=> [tex]A_L[/tex] = 3.14 m.
Hence the arc length is D) 3.14 meters.
