Answers
Therefore , the solution of the given problem of area comes out to be
A = 16 is the equation that accurately depicts how to calculate the sector's area.
What is an area ?Its total size can be determined by figuring out how much space is required to completely cover the outside. The immediate surroundings are taken into consideration when calculating the surface of a trapezoidal shape. The total measurements of something are determined by its surface area. A cuboid's capacity for internal water is determined by the sum of the borders that link all of it's six rectangle edges.
Here,
The formula for calculating a circle's sector's area is:
=> A = (θ/360) x πr²
where A is the sector's area, is its central angle measurement, and r is the circle's radius.
Since the radius is 8 cm and the central angle is 90 degrees in this instance, we can reduce by plugging in these values:
=> A = (90/360) x π(8²)
=> A = (1/4) x π(64)
=> A = π(16)
=> A = 16π
A = 16 is the equation that accurately depicts how to calculate the sector's area.
The answer will be given in radius squared units, in this case, cm2.

Quadrilaterals HIJK and ABCD are congruent. The side length of each square on the grid is 1 unit. Which of the following sequences or transformations maps HIJK to ABCD?
Answers
The sequence of transformations that maps HIJK to ABCD is sequence B: reflection over line HÌ, then a translation 6 units to the right and 3 units down.
What is quadrilateral ?
A quadrilateral is a polygon with four sides and four vertices. The term "quadrilateral" comes from the Latin words "quadri" meaning "four" and "latus" meaning "side". Quadrilaterals can have different shapes and properties, including rectangles, squares, parallelograms, trapezoids, and kites.
Since quadrilaterals HIJK and ABCD are congruent, we can map one onto the other using a sequence of transformations. We need to determine which of the given sequences of transformations maps HIJK to ABCD.
Sequence A involves a 270° rotation about point J, followed by a translation 9 units to the right and 8 units down.
Sequence B involves a reflection over the line HÌ, followed by a translation 6 units to the right and 3 units down.
To determine which sequence maps HIJK to ABCD, we can apply each sequence to the vertices of HIJK and see if the resulting image matches the vertices of ABCD.
Starting with sequence A, we apply the rotation and translation to the vertices of HIJK:
Vertex H(-2, 1) is rotated 270° about J(-2, 2) to get H'(0, 0). Then we translate 9 units to the right and 8 units down to get H''(9, -8).
Vertex I(-3, -1) is rotated 270° about J(-2, 2) to get I'(1, -3). Then we translate 9 units to the right and 8 units down to get I''(10, -11).
Vertex J(-2, 2) is fixed by the rotation and then translated 9 units to the right and 8 units down to get J''(7, -6).
Vertex K(0, 0) is rotated 270° about J(-2, 2) to get K'(-2, -2). Then we translate 9 units to the right and 8 units down to get K''(7, -10).
The resulting image of HIJK under sequence A has vertices H''(9, -8), I''(10, -11), J''(7, -6), and K''(7, -10). We can see that these vertices do not match the vertices of ABCD, so sequence A does not map HIJK to ABCD.
Next, we apply sequence B to the vertices of HIJK:
Vertex H(-2, 1) is reflected over line HÌ to get H'(-4, 3). Then we translate 6 units to the right and 3 units down to get H''(2, 0).
Vertex I(-3, -1) is reflected over line HÌ to get I'(-1, 1). Then we translate 6 units to the right and 3 units down to get I''(5, -2).
Vertex J(-2, 2) is reflected over line HÌ to get J'(-4, 4). Then we translate 6 units to the right and 3 units down to get J''(2, 1).
Vertex K(0, 0) is reflected over line HÌ to get K'(-2, 2). Then we translate 6 units to the right and 3 units down to get K''(4, -1).
The resulting image of HIJK under sequence B has vertices H''(2, 0), I''(5, -2), J''(2, 1), and K''(4, -1). We can see that these vertices match the vertices of ABCD, so sequence B maps HIJK to ABCD.
Therefore, the sequence of transformations that maps HIJK to ABCD is sequence B: reflection over line HÌ, then a translation 6 units to the right and 3 units down.

The experiment that is most likely to produce a uniform discrete distribution is the number of patrons arriving every 3 minutes at a sandwich shop.
Test scores on a college entrance exam, such as the ACT or SAT, is an example of continuous distribution.
What is a uniform discrete distribution?A uniform distribution is a kind of probability distribution in which all of the potential outcomes have an equal likelihood of occurring. A uniform distribution with a limited set of potential outcomes is referred to as a discrete uniform distribution. In a discrete uniform distribution, there is a finite number of potential outcomes that are all equally probable.
It is important to note that the sum of the probabilities of all possible outcomes in a uniform distribution is always equal to 1 since the outcomes are equally likely to happen. The following experiments are less likely to generate a uniform discrete distribution:

Megan is taking out a loan for $6,000 with
an annual compound interest rate of 13%
for 6 years. Megan will not make any
additional deposits or withdrawals. What
will be the total balance paid at the end of 6 X
years?
Round your answer to the closest dollar
amount. Do not include $ symbol in answer
Answers
Steps:
1) The formula for compound interest is x=P(1+r/n)^nt. This means that the final amount (x) is equal to the initial deposit (P) times the result of 1 plus the interest rate (r) divided by the number of times the interest occurs in a given time period (n) to the power of n times the number of time periods (t).
2)Next we have to plug in our information from the problem. We know that the initial deposit (P) was 6000 and the interest rate (r) is .13 (13%), so we can start by plugging those two in. This will get us x=6000(1+.13/n)^nt. Since it occurs annually, we know that the number of times it occurs each year is n, and we also know that the number of years for which she will leave it (t). This gives us n = 1 (since it happens once per year) and t = 6 (since she is leaving it for 6 years). Plugging this in, we get x = 6000(1+.13/1)^1x6. We can simplify this to x = 6000(1+.13/1)^6 since 1x6 is 6.
3) Finally, we need to solve. If you can use a calculator, you may skip this part. However, if you can’t, it goes like this: First, we need to solve everything within the parentheses. .13/1 is still .13, and once we add in the 1 we get 1.13. This gives us x = 6000(1.13)^6. Next, we need to do the exponent. 1.13^6 is about 2.081952. We are unable to round this number yet in order to keep it accurate. After that, we get x = 6000x2.081952. Multiplying those together, we get 12491.712, which rounds to 12491.71.

Given that the measurement is in centimeters, find the circumference of the circle to the nearest tenth. (use 3.14 for π)
Answers
The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle and π (pi) is a constant approximately equal to 3.14.
To find the circumference of the circle, we need to know the radius. If we are not given the radius directly, we may be given another measurement that we can use to calculate it. For example, we may be given the diameter, which is the distance across the circle passing through its center. The radius is half the diameter.
Assuming we have been given the diameter of the circle, we can calculate the circumference as follows:
Write down the formula for the circumference of a circle: C = 2πr
Identify the diameter of the circle. Let's say it is 10 cm.
Calculate the radius by dividing the diameter by 2: r = 10/2 = 5 cm.
Plug in the value of the radius into the formula: C = 2π(5) = 10π.
Use the approximation of π as 3.14: C = 10(3.14) = 31.4 cm.
Therefore, the circumference of the circle is approximately 31.4 cm, to the nearest tenth of a centimeter.

Wilbur flew twice as fast as his brother Orville and therefore made the 852-ft flight in 6 seconds less time. What is each of their rates in feet per second and how many seconds is each of their flights.
Answers
Wilbur's flight took about 43.7 seconds.
How to find the time?Let x be the rate of Orville in feet per second and 2x be the rate of Wilbur in feet per second. Let t be the time it took for Orville to complete the flight and t - 6 be the time it took for Wilbur to complete the flight.
We know that the distance traveled by both brothers is the same, which we can express with the equation:
distance = rate × time
For Orville:
distance = x * t
For Wilbur:
distance = 2x * (t - 6)
Since the distance is the same for both brothers, we can set the two equations equal to each other:
x * t = 2x * (t - 6)
Expanding and simplifying the right-hand side:
xt = 2xt - 12x
12x = xt
x = t/12
So, Orville's rate is x = t/12 feet per second.
Substituting this into one of the equations for distance, we can solve for t:
distance = x * t
852 = (t/12) * t
852 = t² / 12
t² = 12 * 852
t² = 10224
t ≈ 101.1 seconds (rounded to the nearest tenth)
So, Orville's flight took about 101.1 seconds.
Now we can use the equation for Wilbur's distance to find his rate:
distance = 2x * (t - 6)
852 = 2(2x) * (101.1 - 6)
852 = 4x * 95.1
x ≈ 5.64 feet per second (rounded to the nearest hundredth)
So, Orville's rate is about 5.64 feet per second, and Wilbur's rate is twice that or about 11.28 feet per second.
To find Wilbur's time, we can use the equation for distance again:
distance = 2x * (t - 6)
852 = 2(11.28) * (t - 6)
852 = 22.56t - 135.36
22.56t = 987.36
t ≈ 43.7 seconds (rounded to the nearest tenth)
So, Wilbur's flight took about 43.7 seconds.

Answers
Mei worked 8 hours and Kara worked 7 hours when Mei can build a computer in 0.8 hours , and Kara can build a computer in 1 hour.
Let's use the following variables to represent the unknowns in the problem:
Let M be the number of computers Mei built
Let K be the number of computers Kara built
We can set up a system of equations based on the given information:
M + K = 17 (the total number of computers built is 17)
0.8M + K = 15 (the total time worked is 15 hours)
We can solve for one of the variables in terms of the other by using the first equation:
M = 17 - K
Now we can substitute this expression for M into the second equation:
0.8(17 - K) + K = 15
13.6 - 0.8K + K = 15
0.2K = 1.4
K = 7
So Kara built 7 computers. We can use the first equation to find how many computers Mei built:
M + 7 = 17
M = 10
Therefore, Mei built 10 computers.
Now we can find how long each girl worked by multiplying the number of computers by their respective build times:
Mei: 10 computers x 0.8 hours per computer = 8 hours
Kara: 7 computers x 1 hour per computer = 7 hours
Therefore, Mei worked 8 hours and Kara worked 7 hours.

Answers
The correct option to model the height is
h = cosine (StartFraction pi Over 6 EndFraction t) + 9.
Finding the equation to model the height:Here the height of the tip of the hour hand of a wall clock follows a cosine function as the time progresses since the hour hand of a clock completes one full revolution in 12 hours.
We will use the general form of a cosine function to model the height has a function of time t:
h = A cos(Bt) + CWhere A is the amplitude, B is the frequency and C is the vertical shift
Here we have
The height, h, in feet of the tip of the hour hand of a wall clock varies from 9 feet to 10 feet.
Hence, the applitude A = [9+10]/2 = 0.5.
The period of a cosine function is given by 2π/B,
Since the hour hand completes one full revolution in 12 hours, the period is 12 hours or 2π.
=> B = π/6.
The vertical shift is C = 9.
Thus, the equation that models the height h as a function of time t is:
h = 0.5 cos(π/6 t) + 9.
Therefore,
The correct option to model the height is
h = cosine (StartFraction pi Over 6 EndFraction t) + 9.

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction of the bar. ABC rotates 90 degrees clockwise about point p to from A’B’C
Answers
To rotate triangle ABC 90 degrees clockwise about a point P, we can follow these steps:
Draw a line segment from each vertex of the triangle to the point P.
Measure the distance from each vertex to the point P and make note of the lengths.
Rotate each line segment 90 degrees clockwise by swapping the x and y coordinates and changing the sign of the new y-coordinate. For example, if a vertex has coordinates (x, y), the new coordinates after rotation will be (y, -x).
Use the new endpoints of the line segments to draw the new triangle, A'B'C'.
For example, suppose the coordinates of triangle ABC are A(1,2), B(3,4), and C(5,2), and the point of rotation is P(3,3). Then the distances from each vertex to the point P are:
AP = sqrt((3-1)² + (3-2)²) = sqrt(5)
BP = sqrt((3-3)² + (3-4)²) = 1
CP = sqrt((3-5)² + (3-2)²) = sqrt(5)
After rotating each vertex 90 degrees clockwise about P, we get:
A'(4,1)
B'(2,3)
C'(4,5)
Using these new coordinates, we can draw the new triangle A'B'C', which is the result of rotating triangle ABC 90 degrees clockwise about P.

Ahmet borrows $700 and is charged compound interest at 15% per year. How much will he have to pay back in total after 6 years?
Give your answer to two decimal places.
Answers
Answer:
The required amount Ahmet needs to pay after 6 years is $1619.14.
What is compound interest?
Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.
Amount = principal[1 + r/n]ⁿᵃ
Principal = P rate= r Time =a , n = compounding frequency
Here,
From the given data,
P = 700, r = 15% and t = 6 (n =1)
Now,
Amount = principal[1 + r/n]ⁿᵃ
Amount = 700(1 + 0.15)⁶
Amount = $1619.14
Thus, the required amount Ahmet needs to pay after 6 years is $1619.14.

What is the slope of the line?
Answers
Answer:
Slope m = 1/3
Step-by-step explanation:
Slope of the line can be found by taking two points on the line, (x1, y1) and (x2, y2)
Find the difference in y coordinates, y2 - y1 (called rise)
Find the difference in corresponding x coordinates x2 - x1 (called run)
Rise/Run gives the slope
Two distinguishable points on the line graph are (0, 2) and (3, 3)
rise = 3 - 2 = 1
run = 3 - 0 = 3
Slope = 1/3
Gethyn needs to drink 8 cups of water each day. Today he has consumed 48 fluid ounces. How many more cups does he need to drink today?
Answers
By the given parameters, Gethyn needs to drink 2 more cups of water today.
How many more cups does he need to drink today?From the question, we have the following parameters that can be used in our computation:
Amount = 8 cups
Today = 48 ounces
There are 8 fluid ounces in one cup.
So, to convert 48 fluid ounces to cups, we divide by 8:
48 fluid ounces / 8 fluid ounces per cup = 6 cups
Therefore, Gethyn has already drnk 6 cups of water today.
To reach his goal of 8 cups, he still needs to drink:
8 cups - 6 cups = 2 cups
So Gethyn needs to drink 2 more cups of water today.

c. d: [–4, [infinity]) and r: [0, [infinity])
d. d: (4, [infinity]) and r: (–[infinity], 0)
Answers
The domain and range of g of x equals the square root of the quantity x plus 4, g(x) = √x + 4, are equal to d: [–4, [infinity]) and r: [0, [infinity]). Thus, the right choice of answer is option (c).
We have a function g(x) and defined as square root of the quantity x plus 4, i.e.,
g(x) = √x + 4
We have to determine the domain and range of function g(x).
The domain of function is all input values of x that make the expression defined. The range is the set of all output values that valid g(x) values. A square root limits the function because we can't have negative numbers under the square root (they become imaginary numbers). Let y = g(x) = √x +4
the square root '√ 'sign must be implies ≥ 0, therefore, x + 4 ≥ 0
Subtracting the 4 from both sides
=> x + 4 -4 ≥ 0 - 4
=> x ≥ -4
The domain is x∈ [-4,+∞)
When x = -4, g(x) = 0
Therefore, The range is y∈ [0, 00)
