identify the solution of the inequality −3|n 5| ≥ 24 and the graph that represents it.
To solve the inequality −3|n - 5| ≥ 24, we can break it down into two cases: when the expression inside the absolute value is positive and when it is negative.
Case 1: n - 5 ≥ 0
In this case, the absolute value becomes n - 5, so we have:
-3(n - 5) ≥ 24
Simplifying the inequality gives:
-3n + 15 ≥ 24
-3n ≥ 9
Dividing both sides by -3 (and flipping the inequality sign):
n ≤ -3
Case 2: n - 5 < 0
In this case, the absolute value becomes -(n - 5), so we have:
-3(-(n - 5)) ≥ 24
Simplifying the inequality gives:
3n - 15 ≥ 24
3n ≥ 39
Dividing both sides by 3:
n ≥ 13
Combining the solutions from both cases, we find that the solution to the inequality is n ≤ -3 or n ≥ 13. This means n can be any value less than or equal to -3 or any value greater than or equal to 13.
As for the graph representing the solution, it would be a number line with a closed circle at -3 (indicating that it includes -3) and an open circle at 13 (indicating that it does not include 13). The area between -3 and 13 is shaded to represent the values that satisfy the inequality.

required parameters. (e) Write the complex number 5+2i in the exponential form Aeie. (f) A spring-mass system has a natural period of 0.31 second. Calculate the new period if the spring constant is increased by 60%.
(e) The complex number 5+2i in exponential form is (\sqrt{29}e^{i\text{tan}^{-1}\left(\frac{2}{5}\right)}\).
(f) The new period is \(0.31\sqrt{\frac{m}{1.6k}}\) when the spring constant is increased by 60%.
(e) To convert a complex number to exponential form, we need to determine its magnitude and argument. For the complex number 5+2i, the magnitude is given by the formula \(A = \sqrt{{\text{Re}}^2 + {\text{Im}}^2}\) where Re and Im represent the real and imaginary parts, respectively. In this case, the magnitude is \(\sqrt{5^2 + 2^2} = \sqrt{29}\).
The argument, \(\theta\), can be found using the formula \(\theta = \text{tan}^{-1}\left(\frac{{\text{Im}}}{{\text{Re}}}\right)\). For 5+2i, the argument is \(\text{tan}^{-1}\left(\frac{2}{5}\right)\).
Thus, the complex number 5+2i in exponential form is \(Ae^{i\theta} = \sqrt{29}e^{i\text{tan}^{-1}\left(\frac{2}{5}\right)}\).
(f) The period of a spring-mass system is determined by the mass and the spring constant. If the spring constant is increased by 60%, we can calculate the new period using the formula \(T' = T\sqrt{\frac{m}{k'}}\).
Given the original period \(T = 0.31\) seconds and an increase in the spring constant by 60%, we have \(k' = 1.6k\) where \(k\) is the original spring constant.
Substituting the values into the formula, the new period is \(T' = 0.31\sqrt{\frac{m}{1.6k}}\).
Increasing the spring constant causes the spring to become stiffer, resulting in a shorter period. The new period, \(T'\), will be less than the original period \(T\) due to the increased stiffness of the spring.

A shopper pays for 517 for a 470 camera after sales tax is added. What is the sales tax percentage?
If a shopper pays for 517 for a 470 camera after sales tax is added then sales tax percentage is 10%.
To find the sales tax percentage, we will follow these steps:
1. Determine the amount of sales tax paid.
2. Divide the sales tax amount by the original price of the camera.
3. Multiply the result by 100 to find the sales tax percentage.
Step 1: Determine the amount of sales tax paid.
Sales tax amount = Total amount paid - Original price of the camera
Sales tax amount = 517 - 470
Sales tax amount = 47
Step 2: Divide the sales tax amount by the original price of the camera.
Sales tax rate = Sales tax amount / Original price of the camera
Sales tax rate = 47 / 470
Step 3: Multiply the result by 100 to find the sales tax percentage.
Sales tax percentage = Sales tax rate * 100
Sales tax percentage = (47 / 470) * 100
Sales tax percentage ≈ 10%
So, the sales tax percentage is approximately 10%.

Samuel pay 5.81 for the 3 bottles of juice.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
We have to given that;
Samuel buys 3 bottles of juice that each have an original price of 2.80.
And, He uses a coupon for 35% off. Then, he is changed sales tax at a rate of 6.5%.
Here, The original cost of 3 bottles of juice = 3 × 2.80
= 8.40
Now, He uses a coupon for 35% off.
Hence, The off price = 35% of 8.40
= 35/100 × 8.40
= 2.94
So, The amount of 3 bottles of juice = 8.40 - 2.94
= 5.46
And, He is changed sales tax at a rate of 6.5%.
Thus, The sales tax on bottles = 6.5% of 5.46
= 6.5/100 × 5.46
= 0.35
Thus, The actual amount of 3 bottles of juice = 5.46 + 0.35

If a researcher sets the alpha at .05 and obtains a p value of .06, this means that a null hypothesis would
The null hypothesis would not be rejected and the researcher would fail to find statistical significance at the chosen alpha level of .05.
If a researcher sets the alpha level at .05 and obtains a p-value of .06, it means that the p-value is greater than the chosen significance level. The alpha level, also known as the significance level, represents the threshold for determining whether the results are statistically significant or not.
In hypothesis testing, the null hypothesis assumes that there is no significant difference or relationship between variables.
If the p-value is less than or equal to the alpha level, it suggests that there is enough evidence to reject the null hypothesis and conclude that there is a significant difference or relationship.
However, if the p-value is greater than the alpha level, as in this case with a p-value of .06, it means that the observed data does not provide sufficient evidence to reject the null hypothesis.

x = 20
hence angles are

Answer:
A ≈ 1500\(\sqrt{3}\) m²
Step-by-step explanation:
sum the parts of the ratio, 3 + 5 + 7 = 15 parts
Divide perimeter by 15 to find the value of one part of the ratio.
300 ÷ 15 = 20 m ← value of 1 part of the ratio , then
3 parts = 3 × 20 = 60 m
5 parts = 5 × 20 = 100 m
7 parts = 7 × 20 = 140 m
The 3 sides of the triangle are 60 m, 100 m , 140 m
To calculate the area (A) having all 3 sides use Hero's formula
A = \(\sqrt{s(s-a)(s-b)(s-c)}\)
where s is the semiperimeter and a, b , c the sides of the triangle
s = 300 m ÷ 2 = 150 m
let a = 60, b = 100 and c = 140 , then
A = \(\sqrt{150(150-60)(150-100)(150-140)}\)
= \(\sqrt{150(90)(50)(10)}\)
= \(\sqrt{6750000}\)
= \(\sqrt{10000}\) × \(\sqrt{675}\)
= 100 × \(\sqrt{25(27)}\)
= 100 × 5\(\sqrt{27}\)

Infinitely many position vectors with length 2 in xyz-space are orthogonal to the nonzero position vector v. (D)
A position vector in xyz-space is a vector that starts at the origin and ends at a point in xyz-space. The length of a position vector is the distance from the origin to the point it ends at.
If we want to find position vectors with length 2 that are orthogonal (perpendicular) to a given nonzero position vector v, we can use the dot product.
Let w be a position vector with length 2 that is orthogonal to v. Then, the dot product of v and w must be zero, since they are orthogonal. That is, v · w = 0. Since the length of w is 2, we can write w as 2u for some unit vector u. Thus, v · w = v · (2u) = 2(v · u) = 0.
This means that v and u are orthogonal as well, since the dot product of two vectors is zero if and only if they are orthogonal.
There are infinitely many unit vectors u that are orthogonal to v, and therefore, there are infinitely many position vectors with length 2 that are orthogonal to v. Therefore, the answer is (d) infinitely many.

There is a 15 days tour of visiting 5 national parks. There is a
stay of two day at each park. So, 2 multiplied by 5 = 10 days are
spent at staying in those 5 parks. Now the remaining days left are
15
The final itinerary will depend on your preferences, the specific national parks you plan to visit, and the distances between them.
Let's clarify the itinerary for the 15-day tour visiting 5 national parks.
You have a 15-day tour, and you plan to visit 5 national parks. Each park will have a stay of two days.
When you multiply the number of parks (5) by the number of days spent in each park (2), you get a total of 10 days allocated for staying in those 5 parks.
However, there seems to be a discrepancy in the calculation because allocating 10 days for park stays leaves only 5 days remaining, not 15.
To resolve this issue and ensure a 15-day tour, we need to reevaluate the itinerary. Let's assume you want to spend two days at each park, which gives you a total of 10 days for park stays.
To fill the remaining 5 days, you have a few options:
1. Travel Days: You can allocate a day for travel between each park, which would require an additional 4 days. This accounts for the transportation time and allows you to enjoy the journey between the parks.
2. Additional Park Visits: If there are other nearby national parks or attractions in the area, you can extend your tour to include visits to these places. This would allow you to explore more diverse locations and make the most of your 15-day tour.
3. Rest and Relaxation: Alternatively, you might choose to use the extra days for relaxation or leisure activities. You can spend some time enjoying the amenities and attractions available near the parks, such as hiking trails, wildlife observation, or local cultural experiences.
Ultimately, the final itinerary will depend on your preferences, the specific national parks you plan to visit, and the distances between them. Make sure to consider travel times, desired activities, and any additional locations you wish to explore when creating your 15-day tour.

A garden table and a bench cost $755 combined. The garden table costs $95 less than the bench. What is the cost of the bench?
Answer:
The bench costs $425
Step-by-step explanation:
First lets define our variables:
t = garden table
b = bench
Next, we have to use the information to create two formulas. One formula is for the cost of a garden table and a bench. The second is for the cost of the garden table.
t + b = 755
t = b - 95
For the next step, we can solve for be by using the second formula we created and replacing (t) in the first formula:
b - 95 + b = 755
2b - 95 = 755
2b = 850
bench = 425
To find out how much the cost of the cost of the table is, you can plug in the cost of the bench (b) back into the second equation:
t = b - 95
t = 425 - 95
table = 330
