What is keychain?
A metal ring or chain known as a keychain, sometimes known as a key fob or keyring, is used to hang multiple keys on.
You can keep your keys organized on a key ring, which is a metal ring. Through the slots in your keys, you pass the ring.
Typically, it will be bigger than the split ring, and the polished stainless steel style is perfect for adding some lovely colors. The paint, which is a charming keychain in and of itself, gives the Carabiner Clip its lovely color.

show that if w1, w2, w3 is a linearly independent set, then w2 - w3, w1 -w3, w1 - w2u is linearly dependent
Answers
If w1, w2, w3 is a linearly independent set, then w2 - w3, w1 - w3, w1 - w2 is a linearly dependent set.
We can prove this statement by showing that there exist constants c1, c2, and c3, not all zero, such that c1(w2 - w3) + c2(w1 - w3) + c3(w1 - w2) = 0.
Expanding the left-hand side, we get c1w2 - c1w3 + c2w1 - c2w3 + c3w1 - c3w2 = 0.
Rearranging the terms, we get (c2 + c3)w1 + (-c1 - c3)w2 + (c1 + c2)w3 = 0.
Since w1, w2, w3 is a linearly independent set, the coefficients of w1, w2, and w3 in the above equation must all be zero. Thus, we have the system of equations:
c2 + c3 = 0
-c1 - c3 = 0
c1 + c2 = 0
Solving this system of equations, we obtain c1 = -c2 and c3 = -c2. Thus, the only non-zero coefficient is c2, and we have c1(w2 - w3) + c2(w1 - w3) + c3(w1 - w2) = -c2(w2 - w3) + c2(w1 - w3) + (-c2)(w1 - w2) = c2(w1 - w2 - w2 + w3 - w1 + w3) = 0.
Therefore, the set {w2 - w3, w1 - w3, w1 - w2} is linearly dependent.

New packaging for fruit snacks contains 10% less weight than the original packaging. If the new package costs 15% more than the original package, by what fraction did the unit price increase? Express your answer as a common fraction.
Answers
Answer:
5/18
Step-by-step explanation:
Let's say the original packaging was 1 lb of packaging for $1.
The cost was $1/lb.
Then the weight went down by 10% and the price went up by 15%.
Now 0.9 lb of packaging cost $1.15.
The new unit cost is $1.15/(0.9 lb)
The difference is
$1.15/(0.9 lb) - $1/lb =
= $1.15/(0.9 lb) - $0.9/(0.9 lb)
= $0.25/(0.9 lb)
=$25/(90 lb) = $5/(18 lb)
The price went up by 5/18.

id like brainliest but if not its ok!
(i got it wrong the first time but once i looked at it more i found it out)
The phone company A Fee and Fee has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of money per minute used on the phone. If a customer uses 320 minutes, the monthly cost will be $166. If the customer uses 520 minutes, the monthly cost will be $246. A) Find an equation in the form y = m+b, where z is the number of monthly minutes used and y is the total monthly of the A Fee and Fee plan. Answer: y Do not use any commas in your answer. B) Use your equation to find the total monthly cost if 644 minutes are used.
Answers
We know that when the number of minutes used is 320, the monthly cost is $166$. So we can plug those values into the equation and solve for $b$:
$166 = 320m + b$
We also know that when the number of minutes used is 520, the monthly cost is $246$. So we can plug those values into the equation and solve for $b$ again:
$246 = 520m + b$
Now we have two equations with two unknowns:
$166 = 320m + b$
$246 = 520m + b$
We can subtract the first equation from the second equation to eliminate $b$:
$246 - 166 = 520m + b - (320m + b)$
$80 = 200m$
$m = \frac{80}{200} = 0.4$
Now we can plug $m$ into one of the original equations to solve for $b$:
$166 = 320(0.4) + b$
$b = 166 - 128 = 38$
So the equation that represents the monthly cost ($y$) based on the number of monthly minutes used ($z$) is:
$y = 0.4z + 38$
B) To find the monthly cost for 450 minutes, we can plug $z = 450$ into the equation we just found:
$y = 0.4(450) + 38$
$y = 180 + 38$
$y = 218$
So the monthly cost for 450 minutes is $218.

Answer:
4L + 8H = 512 (First answer)
You can take 92 low resolution pictures (second answer)
Step-by-step explanation:
Let L represent the number of low resolution pictures you take and H the number of high resolution pictures you can take.
You only have 512 megabytes.
Therefore, the number of megabytes the low resolution pictures you take plus the amount of megabytes the high rsolution you take in total should be 512
Therefore your equation is:
4L + 8H = 512 (First answer)
You took 18 high resolution pictures, so substitute 18 for H
4L+8(18) = 512
4L+144=512
subtract 144 on both sides
4L=368
divide by 4
L= 92
You can take 92 low resolution pictures

Answers
Validation of the model and answering the question "what are my options" occur in the design phase of the IDC (Intelligence, Design, and Choice) framework.
The IDC framework is a decision-making process that consists of three phases: Intelligence, Design, and Choice. Each phase corresponds to a specific set of activities and objectives.
In the intelligence phase, the focus is on gathering information, identifying the problem or decision to be made, and understanding the factors and variables involved. This phase involves data collection, analysis, and exploration to gain insights and knowledge about the problem domain.
In the design phase, the emphasis is on developing and evaluating potential options or solutions to address the problem or decision at hand. This phase involves creating models, prototypes, or simulations to represent the problem and exploring different alternatives.
Validation of the model is an important aspect of this phase to ensure that the proposed solutions align with the problem requirements and objectives.
The question "what are my options" is a fundamental question that arises during the design phase. It implies the exploration and generation of various possible choices or solutions that can be evaluated and compared.
Therefore, the design phase of the IDC framework encompasses the activities of validating the model and answering the question "what are my options." It involves refining and testing potential solutions to make informed decisions in the subsequent choice phase.

Answer: 26/3
Step-by-step explanation:
\(f(x) = 2x - \frac{4}{3} \\f(5) = 2(5) - \frac{4}{3} \\f(5) = 10 - \frac{4}{3} \\f(5) = \frac{30}{3} - \frac{4}{3} \\f(5) = \frac{26}{3}\)
In this question we need to evaluate the function f(x) = (2x-4)/3 for the question to be solved with perfect answer.
Evaluating a function means:
Replaces or substitutes each variable with the specified number or expression.
Now, according to question we have to replace x with number 5 so we can get the desired solution.
First evaluate by replacing and substituting the function for variable x with number 5 which is x=5. Hence by replacing the given number gives us the following equation
f (5) = (2*5-4)/3
Now, simplifying
f (5) = (10-4)/3
f (5) = (6)/3
f (5) = 2
Hence, the correct answer for this is 2.

A company conducts a survey to measure customer satisfaction on a scale of 1 to 10. The range of customer satisfaction scores is a. 4
To find the range of customer satisfaction scores, we need to calculate the difference between the highest and lowest scores.
The highest score in the given data set is 10, and the lowest score is 6. Therefore, the range is 10 - 6 = 4.
The range is a measure of variability and represents the spread of the data. In this case, the customer satisfaction scores range from 6 to 10, indicating a spread of 4 points on the scale.
It's important to note that the range only considers the highest and lowest scores and does not take into account the distribution of the remaining scores.
Therefore, it provides a limited understanding of the overall variability in customer satisfaction.
