A tree is struck by lightning and snaps off 34 feet above the ground. The top part of the tree, 117 feet long, rests with the tip on the ground, while the broken end rests on the top of the stump.
What angle does the top part of the tree make with the ground?

For want of a nail, the shoe was lost,
For want of a shoe, the horse was lost,
For want of a horse, the rider was lost,
For want of a rider, the battle was lost,
For want of a battle, the kingdom was lost,
And all for the want of a horseshoe nail.
From the above poem, we can deduce that the lack of one horseshoe could be either inconsequential or it could indirectly cause the loss of a war. Some systems are quite sensitive to their starting conditions, so a small change may cause a big difference in the outcome.
Keeping the above in mind, look at the following polynomials:
⦁ y = x
⦁ y = x2
⦁ y = x3
Does a slight change in the degree of the polynomials affect their graphs? If yes, show your results graphically, taking values of x as -3, -2, -1, 0, 1, 2 and 3 in every case.
Answers
The poem For Want of a Nail is a warning about how small things can have large and unforeseen consequences. The lack of a horseshoe could lead to the loss of a horse, which could result in the loss of a rider, which could lead to the loss of a battle.
This shows that a small change can cause a big difference in the outcome. We can see a similar phenomenon in the world of mathematics, where small changes in a function can lead to significant changes in its behavior. For example, the degree of a polynomial can have a dramatic effect on its graph. Let's consider the function y = x². This is a second-degree polynomial, which means that its graph is a parabola. If we change the degree of this polynomial to 1, then we get the function y = x, which is a straight line. If we change the degree of this polynomial to 3, then we get the function y = x³, which is a cubic curve. If we graph these functions for the values of x from -3 to 3, we can see how the slight change in the degree of the polynomial affects their graphs. The graph of y = x² is a parabola that opens upward. TThe graph of y = x is a straight line that passes through the origin. The graph of y = x³ is a cubic curve that passes through the origin and has two turning points. These graphs show that a small change in the degree of the polynomial can have a significant effect on its graph.For such more question on polynomial

3=29 ex. 90+65-180=29
4= 115 vertical angle congruent
5=65 vertical angles are congruent ex 115-180
6=65 35+80-180=65

Answer:
∠1 = 35 ; ∠2 = 65 ; ∠3 = 29 ; ∠4 = 115
∠5 = 65 ; ∠6 = 36 ; ∠7 = 144
Step-by-step explanation:
∠4 = 115 {Vertically opposite angles}
∠5 + 115 = 180 {linear pair}
∠5 = 180 - 115
∠5 = 65
∠2 = ∠5 {Vertically opposite angles}
∠2 = 65
∠1 + 80 +∠2 = 180 {Angle sum property of triangle}
∠1 + 80 + 65=180
∠1 + 145 = 180
∠1 = 180 - 145
∠1 = 35
∠5 + ∠7 + 90 + 61 = 360 {angle sum property of quadrilateral}
65 + ∠ 7 + 90 + 61 = 360

∠7 = 360 - 216
∠7 = 144
∠6 + ∠ 7 = 180 {linear pair}
∠6 + 144 = 180
∠6 = 180 - 144
∠6 = 36
∠3 + ∠4 +∠ 6 = 180 {angle sum property of triangle}
∠3 + 115 + 36 = 180

a family on a trip budgets $800 for meals and hotel accommodations. suppose the price of a meal is $40. in addition, suppose the family could afford a total of eight nights in a hotel if they don't buy any meals. how many meals could the family afford if they gave up two nights in the hotel? a. 2 b. 1 c. 8 d. 5\
Answers
if the family gives up two nights in the hotel, they could afford d) 5 meals
The family has a budget of $800 for meals and hotel accommodations. If they could afford eight nights in a hotel without buying any meals, we can determine the cost of one night at the hotel. To do this, we can divide the total budget by the number of nights:
$800 / 8 nights = $100 per night
Now, let's consider the scenario where the family gives up two nights in the hotel. This would free up $200 from their budget ($100 per night x 2 nights). We can then use this amount to determine how many meals the family can afford by dividing the available funds by the cost of one meal:
$200 / $40 per meal = 5 meals
Therefore, if the family gives up two nights in the hotel, they could afford 5 meals. The correct answer is d. 5.

A 62.0 cm long wire is vibrating in such a manner that it forms a standing wave with three antinodes. (The wire is fixed at both ends.) (a) Which harmonic does this wave represent? O first harmonic O second harmonic third harmonic O fourth harmonic O none of the above
Answers
The wave which represents this harmonic is C. third harmonic represents this wave.
The given length of wire is 62.0 cm, and it is vibrating to form a standing wave with three antinodes. The wire is fixed at both ends. Our task is to determine which harmonic this wave represents.
To find the harmonic, we can use the formula 2L = (nλ), where L represents the length of the wire, n is the number of antinodes, and λ is the wavelength of the wave.
By substituting the given values into the formula, we have:
2L = (nλ)
2 * 62.0 cm = (3 * λ)
124.0 cm = 3λ
Dividing both sides by 3, we get:
41.33 cm = λ
From this calculation, we can conclude that the wavelength of the wave is 41.33 cm.
Now, let's determine the harmonic. The harmonic number is equal to the number of antinodes, which in this case is three. Therefore, the wave represents the third harmonic.
In conclusion, the correct option is (c) third harmonic.

Answer:
The scale drawing is correct for the length;
\(\overline{BC} = 5\dfrac{34}{35} \ in.\)
Step-by-step explanation:
The diagram shows the rectangular cross-section of a roof truss
The given dimension of the side \(\overline{AB}\) of the roof truss scale drawing = 9.5 in.
The actual length of the side \(\overline{AB}\) on the roof truss = 38 feet
The actual length of the side \(\overline{BC}\) on the roof truss = 22 feet
Therefore, the scale of the scale drawing is given as follows;
The scale of the drawing = (Scale dimension)/(Actual dimension)
38 feet = 9.5 inches on the drawing
∴ 1 foot = 9.5 inches/35 = 19/70 inches on the drawing
1 foot = 19/70 inches on the drawing
22 feet = (19/70 inches × 22) on the drawing = \(5\frac{34}{35}\) inches on the drawing
The length of \(\overline{BC}\) on the scale drawing = \(5\frac{34}{35}\) inches.
The perimeter of the patio shown below is 120 feet. Develop a formula to find y in terms of x. Explain your work.
Answers
Answer:
Perimeter of the given patio is \((\pi+6)y + 10x +8\).
Step-by-step explanation:
Let us first label the given patio using the points A, B, C, D, E and F as shown the attachment diagram.
Perimeter of given figure can be found by the following:
Perimeter of polygon ABPCDEQF + Perimeter of semi-circle with diameter as EF.
Let us mark points P and Q on sides AB and FA respectively.
These points P and Q are just opposite to point D. Please refer to attached diagram for details.
As this figure has symmetry so, sides
\(side\ AP =side\ FE\ i.e\ 2y\\side\ AQ =side\ BC\ i.e.\ 2y\\side\ PB =side\ CD\ i.e.\ 3x+5\\side\ QF =side\ DE\ i.e.\ 2x-1\)
Perimeter of polygon APBCDEQF = AP + PB + BC + CD + DE + FQ + QA (Side EF is not on the periphery so it is excluded)
\(\Rightarrow 2y + (3x+5) + 2y + (3x+5) + (2x - 1) + (2x-1) + 2y\\\Rightarrow 6y + 10x + 8 ...... (1)\)
Perimeter of semicircle = \(\pi \times radius\)
Radius of semicircle is y.
\(\text{Perimeter of semicircle = }\pi \times y ...... (2)\)
Adding equations (1) and (2):
\(\text{Total perimeter = }6y + 10x + 8 + \pi y \\\Rightarrow (\pi+6)y + 10x + 8\)
Perimeter of the given figure is \((\pi+6)y + 10x +8\)
Which one of the following is the open intervals on which f(x)=(4−x^2)^2 is decreasing? a) (−[infinity],0)∪(0,2) b) (−[infinity],−2)∪(0,2) c) (−2,0)∪(2,[infinity]) d) (−[infinity],0) e) (0,[infinity])
Answers
The open intervals on which \(f(x) = (4 - x^2)^2\) is decreasing are (0, 2).
Thus, the correct option is (b) (−∞,−2)∪(0,2).
To determine the open intervals on which the function \(f(x) = (4 - x^2)^2\) is decreasing, we need to find the intervals where the derivative of the function is negative.
Let's find the derivative of f(x) using the chain rule:
\(f'(x) = 2(4 - x^2)(-2x)\)
To determine where f(x) is decreasing, we need to find where f'(x) is negative.
Setting f'(x) < 0 and solving for x:
\(2(4 - x^2)(-2x) < 0\)
Simplifying the inequality:
\((4 - x^2)(-2x) < 0\)
Now, let's analyze the sign of each factor:
\((4 - x^2)\) is positive for values of x in the open intervals (-∞, -2) and (2, ∞).
(-2x) is negative for values of x in the open interval (0, ∞).
To determine the overall sign of the expression, we need an odd number of negative factors.
In this case, there is only one negative factor (-2x).
Therefore, the open intervals on which \(f(x) = (4 - x^2)^2\) is decreasing are (0, 2).
Thus, the correct option is (b) (−∞,−2)∪(0,2).

a. P(A)
b. P(B)
c. P(A | B)

a. The probability of a sample having low melanin content (event A) is 0.75.
b. The probability of a sample having high moisture content (event B) is 0.25.c. The probability of a sample having low melanin content given that it has high moisture content (event A | B) is 0.48.d. The probability of a sample having high moisture content given that it has low melanin content (event B | A) is 0.4.
The probabilities, we look at the provided data. Out of the 100 skin samples, 75 samples have low melanin content (event A) and 25 samples have high moisture content (event B). The probability of event A is calculated by dividing the number of samples with low melanin content (45) by the total number of samples (100), resulting in 0.75.
Similarly, the probability of event B is calculated by dividing the number of samples with high moisture content (25) by the total number of samples (100), giving us 0.25.
The probability of event A given event B (P(A | B)), we consider the samples with high moisture content (event B), which is 25. Out of these 25 samples, 12 have low melanin content (event A). So, the probability of event A given event B is obtained by dividing 12 by 25, resulting in 0.48.
The probability of event B given event A (P(B | A)), we focus on the with low melanin content (event A), which is 75. Among these 75 samples, 30 have high moisture content (event B). Hence, the probability of event B given event A is obtained by dividing 30 by 75, resulting in 0.4.

Round your answer to at least three decimal places. Do not round your intermediate calculations. Find P(at least 1 has eliminated jobs during the last year).
Answers
The probability that at least one of the three selected businesses have eliminated jobs during the last year is calculated by the complement of the probability that none of the businesses have eliminated jobs.
Let's denote the event that a business has eliminated jobs as A, and the event that a business has not eliminated jobs as A'. The probability of A is 0.1 (10%), and the probability of A' is 0.9 (90%).
To find the probability that none of the three businesses have eliminated jobs, we multiply the probabilities of A' for each business since the events are independent. So the probability of none of the businesses having eliminated jobs is \((0.9)^3 = 0.729\).
Therefore, the probability that at least one of the businesses has eliminated jobs is 1 - 0.729 = 0.271.
Hence, the probability that at least one of the three selected businesses have eliminated jobs during the last year is approximately 0.271, or 27.1% when rounded to three decimal places.
