Answer:
√(25+12√2) ≈ 6.48
Step-by-step explanation:
You want the length of the longest side, labeled x, in the obtuse triangle with sides of lengths 3 and 4 and angle 135° between.
Law of CosinesThe law of cosines tells you ...
c² = a² +b² -2ab·cos(C)
Using this here, we have a=4, b=3, C=135°:
x² = 4² +3² -2·4·3·cos(135°)
x² = 25 -24(-√2/2) = 25 +12√2
x = √(25 +12√2) ≈ 6.48
A Ferris wheel is 30 meters in diameter and boarded from a platform that is 2 meters above the ground. The six o'clock position on the Ferris wheel is level with the loading platform. The wheel completes 1 full revolution in 10 minutes. The function h(t) gives a person's height in meters above the ground t minutes after the wheel begins to turn. a. Find the amplitude, midline, and period of h(t). Amplitude: meters Period: Midline: h - minutes meters b. How high off the ground is a person after 5 minutes? meters
Answer:
a. The Ferris wheel has a diameter of 30 meters, which means the radius is 15 meters. Since the wheel is boarded from a platform that is 2 meters above the ground, the center of the Ferris wheel is 2 + 15 = 17 meters above the ground.
The function h(t) gives a person's height in meters above the ground t minutes after the wheel begins to turn. Since the Ferris wheel completes one revolution in 10 minutes, the period of h(t) is 10 minutes.
The midline is the average value of the function h(t) over one period, and it is equal to the vertical displacement of the graph from the x-axis. Since the center of the Ferris wheel is 17 meters above the ground, the midline is h = 17 meters.
The amplitude of the function h(t) is the distance between the midline and the maximum or minimum value of the function. The maximum height a person can reach on the Ferris wheel is when they are at the very top of the wheel, which is 17 + 15 = 32 meters above the ground. The minimum height a person can reach on the Ferris wheel is when they are at the very bottom of the wheel, which is 17 - 15 = 2 meters above the ground. So the amplitude of h(t) is 15 meters.
Therefore, the amplitude is 15 meters, the midline is h = 17 meters, and the period is 10 minutes.
b. To find the height of a person after 5 minutes, we can plug t = 5 into the function h(t):
h(5) = 15 sin(2π/10 * 5) + 17
h(5) = 15 sin(π) + 17
h(5) = 2 meters
Therefore, a person is 2 meters above the ground after 5 minutes on the Ferris wheel.

After applying the difference of squares procedure , the factors we get =(7y + 5z)(7y - 5z)
Describe factor?Finding the factors of a given statement is a procedure known as factoring.
For instance, the factors of 12 are 1, 2, 3, 4, 6, and 12 are. The components of x²+ 5x + 6 are (x + 2) and (x + 3), respectively.
What is the square formula difference?Factorization of polynomials is a specific instance of the difference of squares formula. It claims that the product of two squares' sum and differences may be calculated using their difference.
A difference of squares expression is, for instance, a² - b² = (a + b)(a - b).
the phrase 49y² - 25z² can be factored, where
a² - b² = (a + b).(a - b).
Where a=49 , b = 25
After applying the difference of squares procedure, the phrase 49y² - 25z² can be factored, where a² - b² = (a + b).(a - b).
Consequently, 49y - 25z
= 7y + 5z(7y - 5z).

Write the equation of
the circle with diameter
endpoints of (-6, 3) and
(-14, 13).
The midpoint of the line segment connecting the endpoints of the diameter is the center of the circle. We can find the midpoint by averaging the coordinates of the endpoints:
$\sf\implies\:Midpoint\:=\:\left(\frac{-6\:-\:14}{2},\:\frac{3\:+\:13}{2}\right)\:=\:(-10,\:8)$
The radius of the circle is half the length of the diameter, which we can find using the distance formula:
$\sf\implies\:Radius\:=\:\frac{\sqrt{(-6\:-\:(-14))^2\:+\:(3\:-\:13)^2}}{2}\:=\:\frac{\sqrt{160}}{2}\:=\:4\sqrt{10}$
Thus, the equation of the circle is
$\sf\implies\:(x\:+\:10)^2\:+\:(y\:-\:8)^2\:=\:(4\sqrt{10})^2$

Answer:
Step-by-step explanation:
A. The individual events are dependent. The probability of the combined event is:
The probability of drawing a red piece of candy on the first draw is 10/51. Since we do not replace the candy after the first draw, the probability of drawing another red piece of candy on the second draw depends on what happened on the first draw. If a red piece of candy was drawn on the first draw, then there are 9 red pieces of candy left out of 50 total pieces of candy for the second draw. If a non-red piece of candy was drawn on the first draw, then there are still 10 red pieces of candy left out of 50 total pieces of candy for the second draw. Therefore, the probability of drawing two red pieces of candy in a row is:
(10/51) x (9/50) + (41/51) x (10/50) = 0.0698
Rounded to three decimal places, the probability of the combined event is 0.070.
The hypotenuse of a right triangle is 1 cm longer than the longest leg. The shorter leg is 7 cm shorter than the longest leg. Find the dimensions of the triangle.
Answer:
The hypotenuse is 13 cm
The longest leg is 12 cm
The shortest leg is 5 cm
Step-by-step explanation:
Given:
A right triangle
Let's assume, that the longest leg is x, the shortest leg is y and the hypotenuse is z
Let's write 2 equations according to the given information and put them into a system (use the Pythagorean theorem):
[tex]z = \sqrt{ {x}^{2} + {y}^{2} } [/tex]
{√(x^2 + y^2) = x + 1,
{x - y = 7;
Let's make x the subject from the 2nd equation:
x = 7 + y
Replace x in the 1st equation with its value from the 2nd one:
[tex] \sqrt{( {7 + y)}^{2} + {y}^{2} } = (7 + y) + 1[/tex]
[tex] \sqrt{49 + 14y + {2y}^{2} } = 8 + y[/tex]
Square both sides of the equation:
[tex]2 {y}^{2} + 14y + 49 = {(8 + y)}^{2} [/tex]
[tex]2 {y}^{2} + 14y + 49 = 64 + 16y + {y}^{2} [/tex]
Move the expression to the left and collect like-terms:
[tex] {y}^{2} - 2y - 15 = 0[/tex]
a = 1, b = -2, c = -15
Solve this quadratic equation:
[tex]d = {b}^{2} - 4ac = ({ - 2})^{2} - 4 \times 1 \times ( - 15) = 64 > 0[/tex]
[tex]y1 = \frac{ - b - \sqrt{d} }{2a} = \frac{2 - 8}{2 \times 1} = \frac{ - 6}{2} = - 3[/tex]
y must be a natural number, since the length of a triangle's side cannot have negative units
[tex]y2 = \frac{ - b + \sqrt{d} }{2a} = \frac{2 + 8}{2 \times 1} = 5[/tex]
We found the length of the shortest leg
Now, we can find the rest of the dimensions:
x = 7 + 5 = 12
[tex]z = \sqrt{ {12}^{2} + {5}^{2} } = \sqrt{144 + 25} = \sqrt{169} = 13[/tex]

Give a “teacher’s explanation” of why 4/5 = 8/10 using a model and sentences.
The shaded area is the same in both circumstances, implying that 4/5 equals 8/10.
What is the model representation of the fraction?We can use a visual representation of a rectangle divided into five equal segments to understand why 4/5 equals 8/10.
If we shade four of those portions, we have shaded four-fifths of the rectangle.
Let's now divide the same rectangle into ten equal sections, each half the size of one of the five parts we started with.
If we shade in eight of these smaller areas, we will have shaded eight-tenths of the rectangle.
We can observe that the shaded area is the same in both circumstances, implying that 4/5 equals 8/10.
In other words, when we divide a whole into equal parts, we can always discover a fraction of those parts.

What are integers?Integers are made up of zeros, natural numbers, and their additive inverses. Except for the fractional part, it can be represented on a number line.
Let's call the smallest of three successive positive numbers x. The following two consecutive integers would then be x + 1 and x + 2.
The product of the two smaller integers (x and x + 1) is eight times that of the largest integer (x + 2). This can be written as an equation:
x(x + 1) = 8 + (x + 2)
By enlarging and simplifying the left side, we get:
[tex]x^2 + x = x + 10[/tex]
When we subtract x and 10 from both sides, we get:
[tex]x^2 - 9 = 0[/tex]
After factoring in, we get:
(x - 3)(x + 3) = 0
As a result, x = 3 or x = -3. We can disregard the negative solution because we're seeking positive integers and infer that x = 3.

What is a collection of objects or people from whom we gather information?
Solve the following maximization problem graphically.
P(x,y)=82x+50y
subject to
2x+2y≥10
3x+6y≤54
x≥0
y≥0
x≤10
y≤8
Answer:
Step-by-step explanation:
To solve the maximization problem graphically, we first need to graph the constraints and find the feasible region. Then we can find the corner points of the feasible region and evaluate the objective function at each corner point to find the maximum value.
Graphing the constraint 2x + 2y ≥ 10, we get the following line:
2x + 2y = 10
y = 5 - x
Graphing the constraint 3x + 6y ≤ 54, we get the following line:
3x + 6y = 54
y = 9 - 0.5x
We also need to graph the non-negative constraints x ≥ 0 and y ≥ 0, as well as the constraints x ≤ 10 and y ≤ 8, which limit the values of x and y.
The feasible region is the shaded region in the graph. To find the corner points of the feasible region, we can find the points where the lines intersect. There are four corner points: (0, 5), (0, 9), (6, 4), and (10, 0).
Now we can evaluate the objective function at each corner point to find the maximum value:
P(0, 5) = 82(0) + 50(5) = 250
P(0, 9) = 82(0) + 50(9) = 450
P(6, 4) = 82(6) + 50(4) = 652
P(10, 0) = 82(10) + 50(0) = 820
Therefore, the maximum value of the objective function is 820, which occurs at the point (10, 0).
Therefore, the maximum value of P(x,y)=82x+50y subject to the given constraints is 820, and it occurs at the point (10,0).

More than 2.5 standard deviations: X > 125 mg/dl
Less than 2.5 standard deviations: X < 75 mg/dl
Step-by-step explanation:
If a continuous random variable X is normally distributed with mean μ and variance σ², it is written as:
[tex]\boxed{X \sim\text{N}(\mu,\sigma^2)}[/tex]
Given:
Mean μ = 100 mg/dlStandard deviation σ = 10 mg/dlTherefore, if the blood sugar levels are normally distributed:
[tex]\boxed{X \sim\text{N}(100,10^2)}[/tex]
where X is the blood sugar level in milligrams per deciliter.
Converting to the Z distribution:
[tex]\boxed{\textsf{If }\: X \sim\textsf{N}(\mu,\sigma^2)\:\textsf{ then }\: \dfrac{X-\mu}{\sigma}=Z, \quad \textsf{where }\: Z \sim \textsf{N}(0,1)}[/tex]
If David has a blood sugar of 85 mg/dl then X = 85:
[tex]\implies Z=\dfrac{85-100}{10}=-1.5[/tex]
To calculate the percentile, find the area associated with the z-score on the Z Table (attached). Multiply the area by 100 and add a percentage sign:

after four passes through the filtration system, 99.19% of the original contaminants will have been removed from the water sample
How to solve the question?
Each time the water passes through the filtration system, 70% of the contaminants are removed, which means that 30% of the contaminants remain in the water. After the first pass, 30% of the original contaminants are left in the water. After the second pass, 30% of the remaining 30% is left, which is equivalent to 9% of the original contaminants. After the third pass, 30% of the remaining 9% is left, which is equivalent to 2.7% of the original contaminants. Finally, after the fourth pass, 30% of the remaining 2.7% is left, which is equivalent to 0.81% of the original contaminants.
Therefore, after four passes through the filtration system, 99.19% of the original contaminants will have been removed from the water sample. This calculation can be obtained by subtracting the final percentage of contaminants left (0.81%) from 100%.
It's important to note that while passing the water through the filtration system multiple times increases the overall percentage of contaminants removed, it's not a substitute for regular maintenance and replacement of the filtration system's components. Over time, the filtration system's effectiveness can diminish, and it's crucial to follow the manufacturer's instructions for proper maintenance and replacement to ensure that the system continues to function optimally.

Find the midpoint, M, of AB.
A = (-3,-1) B = (-7,-7)
Answer:
M=(-5,-4)
Step-by-step explanation:
The midpoint of the line segment AB with coordinates A = (-3, -1) and B = (-7, -7) is (-5, -4).
Explanation:To find the midpoint of a line segment AB, we can use the midpoint formula. The midpoint formula states that the x-coordinate of the midpoint is the average of the x-coordinates of A and B, and the y-coordinate of the midpoint is the average of the y-coordinates of A and B.
Given A = (-3, -1) and B = (-7, -7), we can use the midpoint formula as follows:
x-coordinate of M = (x-coordinate of A + x-coordinate of B) / 2 = (-3 + -7) / 2 = -5y-coordinate of M = (y-coordinate of A + y-coordinate of B) / 2 = (-1 + -7) / 2 = -4Therefore, the midpoint M of AB is (-5, -4).

The area of a rectangular field is equal to the area of a square. The length of the
rectangular field is 4 times the width. The cost of rope per metre is Tk 7. The
cost of the rope to make fence twice around the field is Tk 5600.
a) What will be the perimeter of the rectangular field?
b)
If you sow a papaya plant in every 4 m2 area how many papaya plants will
be needed?
Let's assume that the area of the rectangular field is x square meters, and the width of the field is y meters. Then we know that:
x = y * 4 (since the length of the rectangular field is 4 times the width)
And we also know that the area of the rectangular field is equal to the area of a square. Therefore:
x = y^2
Combining these two equations, we get:
y^2 = y * 4
y = 4 meters
So the width of the rectangular field is 4 meters. Using this, we can find the length:
x = y * 4 = 4 * 4 = 16 square meters
Now, to find the perimeter of the rectangular field:
Perimeter = 2 * (length + width) = 2 * (16 + 4) = 40 meters
Therefore, the perimeter of the rectangular field is 40 meters.
Next, we need to find the number of papaya plants that can be sown in the area of the field. The total area of the field is 16 square meters. If one papaya plant is sown in every 4 square meters, then the number of plants required would be:
Number of plants = Total area / Area per plant
Number of plants = 16 / 4 = 4 plants
Therefore, 4 papaya plants can be sown in the rectangular field.

The expression for the total combined profit that John made from the sales of MP3 and DVD players last week is: 18x + 35(128 - x) dollars.
How to obtain the equationTo arrive at the expression, we should first note that if x is the number of DVD players sold by John last week, then the number of MP3 players sold by John last week would amount to:
(128 - x), because the total number of players sold for both MP3 and DVD was 128.
Next, the total profit made by John from selling x DVD players is 18x dollars, since he makes a profit of $18 for a unit of DVD player sold.
In the same vein, the total profit made by John from selling (128 - x) MP3 players is 35(128 - x) dollars, since he makes a profit of $35 for each MP3 player sold.
In conclusion, the expression for the total combined profit John made from selling the DVD and MP3 players last week is: 18x + 35(128 - x) dollars.
