Answers
m/ABC=86° (because of the cyclic quadrilaterals). Hence, Option (B) is correct.
A cyclic quadrilateral is a four-sided polygon whose vertices all lie on a common circle.
The opposite angles of a cyclic quadrilateral have a total of 180°.
m/ABC + m/ADC = 180°
m/ABC + 94° = 180°
m/ABC = 180° - 94°
m/ABC = 86°
Similarly, one can find m/DCB
m/DAB + m/DCB = 180°
99° + m/DCB = 180°
m/DCB = 180° - 99°
m/DCB = 81°
Hence, m/ABC = 86°

What is The Structure of a Proof?Either two columns or a paragraph can be used to write a geometric proof. A two-column proof stated in sentences is all that a paragraph proof is. But since it's simpler to omit stages when writing a paragraph proof, we'll study the two-column technique.A list of assertions and the justifications for each assertion are included in a two-column geometric proof. The reasons why the claims are true are mentioned in the right column, while the statements themselves are listed in the left column. A row in the two-column proof represents each phase of the proof, or each conclusion reached.Make the illustration of the proof-in-use in a figure. Either the figure will be drawn for you already, or you will need to draw it yourself.List the assertions that are made, and then the assertions that must be proven. At this point, the proof has a start and a finish.Based on what you can infer about the figure from the provided details, mark it accordingly. You actually learn how to make the proof at this stage of the proof process, as well as whether or not you can support the assertion that has been stated.Mark any congruent sides, angles, etc. so you can see for yourself what has to be said in the evidence to persuade the reader that you are correct in your conclusion.Without omitting even the simplest, carefully note down each step. The stated statements are frequently among the initial steps (though not always), and the conclusion you want to prove is the last step.To Learn more About geometric proof refer To:

Answer:
f(x) = -5/9x - 11/9
Step-by-step explanation:
Consider f(x) = y
so if x = -4 => y = 1 and x = 5 => y = -4
so (-4,1) and (5,-4) should be on the same linear equation
Slope m = (y2 - y1)/(x2 - x1)
m = (-4 - 1)/(5 - -4) = (-5)/(9) = -5/9
y = mx + b
given m = -5/9, x = -4, y = 1
1 = -5/9(-4) + b
b = 1 - 20/9
b = 9/9 - 20/9 = -11/9
so y = -5/9x - 11/9
or f(x) = -5/9x - 11/9

The perimeter of rectangles MATH is 152 cm. Theratio of the length to width is 5:14. What is the widthof the rectangle? What is the area of the rectangle?
Answers
Solution:
Given:
\(\begin{gathered} \text{The ratio of length to width of a rectangle=5:14} \\ \text{Perimeter}=152\operatorname{cm} \end{gathered}\)Thus,
\(\begin{gathered} l\colon w=5\colon14 \\ \frac{l}{w}=\frac{5}{14} \\ \text{Cross multiplying,} \\ w\times5=l\times14 \\ 5w=14l \\ \text{Dividing both sides by 14 to make l subject of the formula,} \\ \frac{5w}{14}=l \\ l=\frac{5w}{14} \end{gathered}\)Also, recall that the perimeter of a rectangle is given by;
\(P=2(l+w)\)Hence,
\(\begin{gathered} P=2(l+w) \\ 152=2(\frac{5w}{14}+w) \\ \frac{152}{2}=\frac{5w}{14}+\frac{w}{1} \\ 76=\frac{5w+14w}{14} \\ 76=\frac{19w}{14} \\ \text{Cross multiplying,} \\ 76\times14=19w \\ 1064=19w \\ \text{Dividing both sides by 19 to get the value of w,} \\ \frac{1064}{19}=w \\ w=56\operatorname{cm} \\ \\ \\ \text{Substituting the value of w gotten into;} \\ 5w=14l \\ 5\times56=14l \\ 280=14l \\ \text{Dividing both sides by 14 to get the value of }l \\ \frac{280}{14}=l \\ l=20\operatorname{cm} \end{gathered}\)Therefore, the length of the rectangle is 20cm.
The width of the rectangle is 56cm.
To get the area of the rectangle,
\(\begin{gathered} \text{Area}=\text{length x width} \\ A=l\times w \\ A=20\times56 \\ A=1120\operatorname{cm} \end{gathered}\)Therefore, the area of the rectangle is 1120 square centimeters.
Sally owns a restaurant in Wooville. The city is trying to get a minor league team to move there in 2021, either to location A (near her restaurant) or location B. The team might stay in location C in another city. The probability of these events, and her estimated annual profit in 2021 are shown in the table below.
Answers
The standard deviation of the restaurant profits in 2021 is given by $71181.
Restaurant profit for outcome 'move to A' = $ 260000
Restaurant profit for outcome 'move to B' = $ 120000
Restaurant profit for outcome 'stay in C' = $ 100000
The mean of restaurant profits = $(260000 + 120000 + 100000)/3 =$ 160000.
Standard deviation of the restaurant profits in 2021 is given by
= $ √({(260000 - 160000)² + (120000 - 160000)² + (100000 - 160000)²}/3)
= $ √(((100000)² + (40000)² + (60000)²)/3)
= $ √(15200000000/3)
= $ √5066666667

if one 30 60 90 triangle has a short leg 8 inches long,and another has a short leg of 24 inches long, find the area of each triangle, and compare their sizes
Answers
Answer:
The triangle with a short leg= to 24 inches is times larger than the one with a short side equalling 8 in
Step-by-step explanation:
Given that the short leg is equal to 8, the longer leg is equal to 8\(\sqrt{3\\\) . The area of a triangle is equal to 1/2bh. 1/2× 8\(\sqrt{3\\\)×8 = 55.43 approx.
Given that the short leg is equal to 24, the longer leg is equal to 24\(\sqrt{3\\\) . The area of a triangle is equal to 1/2bh. 1/2 × 24\(\sqrt{3\\\) ×24 = 498.83 approx.
498.83/55.43= about 9
The second triangle is approximately 9 times the size of the first.
The product of two numbers is 155952. If one number is 342, find the other

The displacement (in centimeters) of a particle moving back and forth along a straight line is given by the equation of motion s = 2 sin(πt) + 5 cos(πt), where t is measured in seconds.
A) Find the average velocity during each time period.
1) [1, 2]
2) [1, 1.1]
3) [1, 1.01]
4) [1, 1.001]
B) Estimate the instantaneous velocity of the particle when t = 1. cm/s
Answers
Answer:
A) 10, -3.73, -6.035, -6.259 . . . cm/s
B) -6.2832 cm/s
Step-by-step explanation:
A) For problems like this, where repeated evaluation of a function is required, I find a graphing calculator or spreadsheet to be an appropriate tool. The attached shows that we defined the position function ...
p(t) = 2sin(πt) +5cos(πt)
and a function for computing the average velocity from t=1. For some time interval ending at t2, the average velocity is ...
Va(t2) = Δp/Δt = (p(t2) -p(1))/(t2 -1)
Then, for example, for t2 = 2, the average velocity on the interval [1, 2] is ...
Va(2) = (p(2) -p(1))/(2 -1) = ((2sin(2π) +5cos(2π)) -(2sin(π) +5cos(π)))/(1)
= (2·0+5·1 -(2·0 +5·(-1)) = 10 . . . . matches the table value for x1 = 2.
Then the average velocity values for the intervals of interest are ...
1) [1, 2] Va = 10
2) [1, 1.1] Va = -3.73
3) [1, 1.01] Va = -6.035
4) [1, 1.001] Va = -6.259
__
B) Sometimes a better estimate is obtained when the interval is centered on the point of interest. Here, we can compute the average velocity on the interval [0.999, 1.001] as a better approximation of the instantaneous velocity at t=1. That value is ...
[0.999, 1.001] Va = -6.283175*
Our estimate of V(1) is -6.2832 cm/s.
The exact value is -2π ≈ -6.2831853... cm/s
__
* This is the average of the Va(0.999) and Va(1.001) values in the table.

Answers
Answer:
6 girls were there are first
Step-by-step explanation:
use trial and error. divide 1200 by a random number like 10, and see how much they each had to pay. If we guessed 10, then each girl would hypothetically pay 120 pounds. If four girls left, then 1200/6 would be 200 pounds. there was only a 60 pound increase here, not a 400 pound one.
I checked 1200/6 which equals 200 pounds per girl. If 4 girls left, then it would be 600 pounds for the 2 remaining girls. the rent increased from 200 to 600 which is a 400 pound increase.

Answer:
What is a linear function? A linear function is a function whose graph is a straight line. The rate of change of a linear function is constant. The function shown in the graph below, y = x + 2, is an example of a linear function.
Graph of linear function
Graph of linear function
A linear function has a constant rate of change. The rate of change is the slope of the linear function. In the linear function shown above, the rate of change is 1. For every increase of one in the independent variable, x, there is a corresponding increase of one in the dependent variable, y. This gives a slope of 1/1 = 1.
A linear function is typically given in the form y = mx + b, where m is equal to the slope, or constant rate of change.
Examples of linear functions include:
If a person drives at a constant speed, the relationship between the time spent driving (independent variable) and the distance traveled (dependent variable) will remain constant.
Assuming no change in price, the relationship between the number of pounds of bananas a person buys (independent variable) and the total cost of the bananas (dependent variable) will remain constant.
If a person earns an hourly wage at their job, the relationship between the time spent working (independent variable) and the amount earned (dependent variable) will remain constant.

Exponential Functions
What is an exponential function? An exponential function is a function that involves exponents and whose graph is a smooth curve. The rate of change in an exponential function is not constant. The functions shown in the graph below, y = 0.5x and y = 2x, are examples of exponential functions.
Graphs of exponential functions
Graphs of exponential functions
An exponential function does not have a constant rate of change. The rate of change in an exponential function is the value of the independent variable, x. As the value of x increases or decreases, the rate of change increases or decreases as well. Rather than a constant change, as in the linear function, there is a percent change.
An exponential function is typically given in the form y = (1 + r)x, where r represents the percent change.
Examples of exponential functions include:

Answers
For the function f(x) = 2x + 3 the third iterate x₃ is 37
To find the third iterate, x3, of the function f(x) = 2x + 3, given an initial value of x₀ = 2,
we can apply the function repeatedly.
Starting with x₀ = 2:
x₁ = f(x₀)
= 2(2) + 3
= 7
x₂ = f(x₁)
= 2(7) + 3 = 17
x₃ = f(x₂)
= 2(17) + 3
= 37
Therefore, the third iterate x₃ is 37.

What is a circle graph?A circle graph, often called a pie chart, is a circular graph with sectors on it, each representing a particular category or set of data. Each sector's area or angle is proportionate to the amount it stands for. In data visualisation, circle graphs are frequently used to show the relative sizes or proportions of several categories or groups within a dataset. They can instantly convey the distribution of data without the need for laborious numerical calculations, which makes them effective for presenting data that is divided into discrete groups. However, if the data is not presented in a clear and simple manner or if the sectors are not precisely drawn to scale, circle graphs may be deceiving.
Part A: The percentage of green beans in the circle graph is 14%.
14% of 200 = 0.14 x 200 = 28
Part B: The circle graph shows:
pumpkin plants and tomato plants is 20% + 20% = 40%.
40% of 200 = 0.40 x 200 = 80
Part C: The corn plants is 36% and the percentage of cucumber plants is 10%.

A) sec(θ) = -3/2 and tan(θ) = 2/√5C) cos(θ) = -(√5)/3 and tan(θ) = 2/√5How to find the possible expressions?Since sec(θ) is negative, cos(θ) is also negative (sec(θ) = 1/cos(θ)). This means θ is in the second or third quadrant, but since sin(θ) is negative, θ must be in the third quadrant. Now let's check if the given tan(θ) value is correct:
tan(θ) = sin(θ)/cos(θ)
Since we already know that cos(θ) is negative, we have cos(θ) = -(√5)/3.
Now calculate tan(θ):
tan(θ) = (-2/3) / (-(√5)/3) = 2/√5
The given values in option A are correct.
cos(θ) = -(√5)/3 and tan(θ) = 2/√5

g(2) = 1/4 × f(2) = 1/4 × 4 = 1
and equally for x = -1 and -2.
a square function always delivers positive numbers. and so does the square function multiplied by a positive constant (like for g(x)).
the only graph, where the curve is always above the x-axis (only positive results), and where the functional value for x = 1 is much smaller than 1, and the functional value for x = 2 is actually 1, is graph D.
