The list that has the angles of AABC in order from smallest to largest is: ZC, ZA, ZB

The measure of the angles of the triangle in order from smallest to largest is ∠C , ∠A , ∠B

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

And , In AABC, AB= 7, BC= 8, and AC=9

We can use the Law of Cosines to determine the size of each angle in AABC:

cos A = (b^2 + c^2 - a^2) / (2bc)

cos B = (a^2 + c^2 - b^2) / (2ac)

cos C = (a^2 + b^2 - c^2) / (2ab)

Plugging in the values of a = 9, b = 7, and c = 8, we get:

cos A = (7² + 8² - 9²) / (2 x 7 x 8) = 39/112

cos B = (9² + 8² - 7²) / (2 x 9 x 8) = 17/18

cos C = (9² + 7² - 8²) / (2 x 9 x 7) = 5/14

Taking the inverse cosine of each value gives:

A = cos^-1(39/112) ≈ 62.02°

B = cos^-1(17/18) ≈ 26.56°

C = cos^-1(5/14) ≈ 91.42°

And , the longest side in a triangle is always opposite the largest angle, and the shortest side is opposite the smallest angle and ∠C , ∠A , ∠B

Hence , the triangle is solved

Therefore, the volume of a single Rh atom is approximately 1.011 × 10^(-29) m^3.

The diameter of a single Rh atom is given as 2.7 × 10^(-8) cm. The radius of the atom, which is half of the diameter, is therefore:

r = 2.7 × 10^(-8) cm / 2 = 1.35 × 10^(-8) cm

To find the volume of the sphere, we can use the formula:

V = (4/3)πr^3

where π is the constant pi.

Substituting the values, we get:

V = (4/3)π(1.35 × 10^(-8) cm)^3

= 1.011 × 10^(-23) cm^3

However, the answer is required in m^3, so we need to convert cm^3 to m^3. We know that:

1 cm = 0.01 m

Therefore:

(1 cm)^3 = (0.01 m)^3

1 cm^3 = 1 × 10^(-6) m^3

Substituting this conversion factor, we get:

V = 1.011 × 10^(-23) cm^3 × 1 × 10^(-6) m^3/cm^3

= 1.011 × 10^(-29) m^3

Answer:

x=7

y=8

(x+y)= 15

(x-y)= -1

Step-by-step explanation:

let x and y be the numbers

x + y = 15 ------ 1

2x - y = 6 ------ 2

add both equation 1 and 2

3x = 21

x = 21\3

x=7

subtitute 7 for x in equation 1

7 + y = 15

y = 15-7

y=8

The first number x = 7

The second number y = 8

thus x + y = 7 + 8 = 15

x - y = 7 - 8 = -1

Step-by-step explanation:

The given nonlinear system, described by the input-output equation y[n] = y^2[n−1] + x[n], with input x[n] = Aδ[n], is not BIBO stable.

BIBO stability (Bounded-Input Bounded-Output stability) refers to the property of a system where if a bounded input is applied to the system, the output remains bounded. A BIBO stable system ensures that the output does not grow indefinitely or become unbounded in response to a bounded input.

In the given nonlinear system, the equation y[n] = y^2[n−1] + x[n] represents a recursive relationship between the current output y[n] and the previous output y[n−1] and the current input x[n]. The input is a discrete impulse, x[n] = Aδ[n], where A is a constant.

For this system, we can observe that the output at each time step depends on the square of the previous output, y^2[n−1]. As a result, the system has the potential to exhibit exponential growth or instability if the initial output value y[−1] is nonzero.

Given that y[−1] = 0, the initial output value is zero, which helps in avoiding immediate instability. However, it does not guarantee BIBO stability. Even with a bounded input, the system can produce unbounded or divergent output values over time due to the recursive relationship involving the square term.

Therefore, based on the given equation and conditions, the system described is not BIBO stable.

The minimum yield value of the key material should be determined based on the yield stress of the shaft, which is 36 kg/m², the dimensions of the key, and the safety factor of 2.

To ensure that the key smoothly transmits the torque of the shaft, it is essential to choose a key material with a minimum yield value that can withstand the applied forces without exceeding the yield stress of the shaft.

The dimensions of the key given are 20x20x120 mm. To calculate the torque transmitted by the key, we need to consider the dimensions and the applied forces. However, the specific values for the applied forces are not provided in the question.

The safety factor of 2 indicates that the material should have a yield strength at least twice the expected yield stress on the key. This ensures a sufficient margin of safety to account for potential variations in the applied forces and other factors.

To determine the minimum yield value of the key material, we would need additional information such as the expected torque or the applied forces. With that information, we could calculate the maximum stress on the key and compare it to the yield stress of the shaft, considering the safety factor.

Please note that without the specific values for the applied forces or torque, we cannot provide a precise answer regarding the minimum yield value of the key material.

The minimum amount of workdays the plant will require is 10.

Let's calculate the production rate of the manufacturing plant in chocolate bars per hour:

120 bars / 5 minutes = 24 bars/minute

24 bars/minute * 60 minutes/hour = 1440 bars/hour

The plant is open for 8 hours, minus a 30-minute lunch break, which is equivalent to 7.5 hours of work.

Now, we can calculate the number of chocolate bars produced in a day:

1440 bars/hour * 7.5 hours/day = 10,800 bars/day

To find the fewest number of work days needed to produce 100,000 chocolate bars, we divide 100,000 by 10,800:

100,000 bars / 10,800 bars/day ≈ 9.26 days

Since we're looking for a whole number representing the fewest number of work days, we round up to the nearest whole number.

To find all points with a specific x-coordinate, you need to have the equation of the curve or the data points representing the graph. If you have an equation, you can substitute the desired x-coordinate into the equation and solve for the corresponding y-coordinate.

If you have data points, you can look for the points that have the specified x-coordinate.

For example, let's say you have the equation of a line: y = 2x + 3. If you want to find all points with an x-coordinate of 5, you can substitute x = 5 into the equation to find y. In this case, y = 2(5) + 3 = 13. So the point (5, 13) has an x-coordinate of 5.

The ratios of successive numbers in the Fibonacci sequence eventually get closer to a. 1.61

In mathematics, the Fibonacci sequence is a sequence in which each number is the sum of the two preceding ones. Numbers that are part of the Fibonacci sequence are known as Fibonacci numbers, commonly denoted Fn . The sequence commonly starts from 0 and 1, although some authors start the sequence from 1 and 1 or sometimes (as did Fibonacci) from 1 and 2.

The Fibonacci sequence is a series of numbers where each number is the sum of the two preceding ones, usually starting with 0 and 1 (0, 1, 1, 2, 3, 5, 8, 13, ...). When you take the ratio of successive numbers in the sequence (e.g., 5/3 or 8/5), it converges to approximately 1.618, also known as the Golden Ratio or Phi.

The Dollar Price of the bond $4813.26

The bond's present value (PV) represents the estimated future cash payments that will result from the bond. The value is equal to the sum of the discounted present values of the interest payments and the redemption value (RV).

Bond value equals PV of interest plus PV of RV

The Local School District's bond amount can be calculated as follows:

PV of interest payments

Semi annual interest payment:

= 2.9% × 5000× 1/2= 72.5

Semi-annual yield = 2.7/2 = 1.65%

Total period to maturity = (2 × 16) = 32 periods

PV of interest payment:

=72.5× (1- (1+0.016)^(-32)/0.016)

= 1804.66

PV of Redemption Value

= 5000× (1.016)^(-32)

The slope-intercept equation of the line passing through the point (6,-6) and parallel to the line x=-4 is y = -6. The slope-intercept equation of the line passing through the point (6,-6) and perpendicular to the line x=-4 is x = 6.



Parallel lines have the same slope, so we first need to find the slope of the line x = -4. Since it is a vertical line, its slope is undefined. So we can't directly apply slope-intercept equation y = mx + b. However, we can still determine the equation of the parallel line passing through (6,-6) since the y-coordinate of the given point is -6. Therefore, the equation of the parallel line is y = -6 (the y-intercept is -6).

Now, to find the equation of the perpendicular line passing through (6,-6), we first need to find the slope of the line x = -4. Since the slope is undefined, the slope of the perpendicular line will be zero. Thus, the equation of the perpendicular line passing through (6,-6) will be x = 6 (the x-intercept is 6).

Answer:

Rebecca originally had 240 dollars.

Step-by-step explanation:

Let's set B as Rebecca's money and C as Rachel's.

Rebecca has twice as much money as Rachel

B = 2C

If Rebecca gives Rachel $60, then the two of them will have the same amount of money

B - $60 = C + $60

let's combine the 2 by subtracting the second from the first

B - (B - $60) = 2C - (C + $60)

$60 = C - $60

$120 = C

so Rachel had 120 dollars.

Rebecca had twice as much, so 240 dollars.

If Rebecca gives $60 to Rachel, they have $180 each. Everything checks out.

The coordinate plane, also known as the Cartesian plane, is a two-dimensional plane that is used to plot and locate points using a set of two perpendicular axes. The horizontal axis is called the x-axis and the vertical axis is called the y-axis.

The point where the two axes intersect is called the origin, which is usually denoted by the coordinates (0,0).

Each point in the plane can be located by its unique pair of coordinates (x,y), where x represents the horizontal distance from the origin and y represents the vertical distance from the origin.

To find the slope of the line passing through vertices A and B, we need to use the formula:

slope \(= (y2 - y1)/(x2 - x1)\)

Where (x1, y1) and (x2, y2) are the coordinates of the two points.

To find the slope of the line passing through vertices A(-2, 1) and B(-4, 2), we can use the slope formula:

slope = (change in y)/(change in x)  \(= (y2 - y1)/(x2 - x1)\)

Substituting the coordinates of A and B into the formula, we get:

slope  \(= (2 - 1)/(-4 - (-2)) = 1/-2 = -1/2\)

Therefore, the slope of the line passing through vertices A and B is -1/2.
