3 (a) To solve 2557⋅X=457 for X∈Z57 using Euclid's algorithm, take the GCD of 2557 and 457. That is, the GCD is:
GCD(2557, 457) = GCD(2557 - 457, 457)
= GCD(2157, 457)
= GCD(757, 457)

2) (3 pts) Independently, find the value of the determinant of the coefficient matrix by performing row operations on it; to reduce it to an echelon (upper triangular) form. Note that you need to show row operations on the determinant, not the matrix. Keep in mind the properties in Theorem 3.13 in section 3.7.3 of the textbook. Once converted to an echelon (upper triangular) form, the value of the determinant is simply the product of diagonal elements. Indicate the row operations by using conventions in the class/videos. Go through solved example 3.7 in that section if necessary. If you show row operations on the matrix, you will receive 0 points even if your answer is correct. If you use conventions outside of class/videos you will receive 0 points even if your answer is correct
-3x + (0)y - 6z = 11
(5)x - 2y + 3z = 17
2x - y - (7)z = -3
product of diagonal elements is 10 x -2 = -20.
To find the value of the determinant of the coefficient matrix, perform row operations to reduce it to an echelon form. First, multiply the first row by -3, the second row by 5, and the third row by 2. This yields the following matrix:
(-9)x + (0)y - 18z = -33
(25)x - 10y + 15z = 85
(4)x - (2)y - 14z = -6
Next, subtract the first row from the second row and the first row from the third row. This yields the following matrix:
(0)x + (10)y - (18)z = 52
(4)x - (2)y - (14)z = -6
Finally, subtract 4 times the second row from the third row. This yields the following matrix:
(0)x + (10)y - (18)z = 52
(0)x - (0)y - (2)z = -24

What is the decimal multiplier to increase by 6.1%? Give me the answer pleaseeeeee
The decimal multiplier to increase by 6.1% is 1.061.
What is multiplication ?
Multiplication is a mathematical operation used for finding the result of adding a number to itself a certain number of times. It involves multiplying two or more numbers to find their product. For example, 2 times 3 is equal to 6, written as 2 x 3 = 6. In multiplication, the numbers being multiplied are called factors, and the result is called the product. Multiplication is often denoted by the symbol "x" or a dot ".".
A decimal multiplier is a factor that is used to increase or decrease a number by a certain percentage. It is commonly used in financial calculations such as interest rates, discounts, and taxes.
To find the decimal multiplier to increase by a certain percentage, you can use the following formula:
Decimal multiplier = 1 + (percentage increase/100)
For example, if you want to increase a number by 6.1%, the decimal multiplier would be:
Decimal multiplier = 1 + (6.1/100)
Decimal multiplier = 1.061
This means that to increase a number by 6.1%, you would multiply it by 1.061. For example, if you had a number of 100, to increase it by 6.1%, you would multiply it by 1.061 to get 106.1.
On the other hand, if you wanted to decrease a number by a certain percentage, you would use a decimal multiplier that is less than 1. For example, to decrease a number by 10%, the decimal multiplier would be 0.9, which means you would multiply the number by 0.9 to get the new decreased value.
Therefore, decimal multiplier to increase by 6.1% is 1.061.

A valid inference is one that is true about the ____ based on a ____
A valid inference is a conclusion that is true about the subject based on the evidence or premises provided.
Mathematically, we can represent a valid inference using logical notation. In the example above, we can use the following notation:
Premise 1: All humans are mortal.
Premise 2: Samantha is a human.
Conclusion: Samantha is mortal.
We can use the logical connective "if-then" to represent a valid inference. In this case, we can say, "If all humans are mortal, and Samantha is a human, then Samantha is mortal." This statement is true based on the premises provided.
To determine the validity of an inference mathematically, we can use rules of logic such as the law of detachment or the law of syllogism. The law of detachment states that if we have a conditional statement, "If p, then q," and we know that p is true, then we can validly infer that q is also true.
The law of syllogism is another rule of logic that helps us determine the validity of an inference. This rule states that if we have two conditional statements, "If p, then q," and "If q, then r," we can infer that "If p, then r" is true.

As more people hear about it, the number of people who listen to the video How mainy new people listen to the video on the 7th day? Round to the nearest increases by 45% each day Whole number according to the context of the problem______people
Assuming the number of people who listen to the video increases by 45% each day, there would be approximately 24 new people who listen to the video on the 7th day after the initial 8 people.
According to the problem, the number of people listening to the video increases by 45% each day. Therefore, we can use the formula for compound interest to calculate the number of new people who listen to the video on the 7th day.
Let P be the initial number of people who listened to the video, which is 8.
Let r be the daily increase rate, which is 45% or 0.45 as a decimal.
Let n be the number of days, which is 7.
Then, the formula for compound interest is:
A = P(1 + r)^n
where A is the final number of people who listen to the video.
Plugging in the values, we get:
A = 8(1 + 0.45)^7
A ≈ 32
Therefore, the number of new people who listen to the video on the 7th day is approximately 32 - 8 = 24 people.

if the solution of an equation is x=-2, what could the original equation be? A. x+6=8 B. x-6=8 C. x+8=6 D. x-8=6
Answer:
C: x+8= 6
Step-by-step explanation:
So if you were to work each of these out x + 6 = 8 that problem gives us positive 2, when we are looking for a -2 so that answer is ruled out. Then you go to x-6=8 you move the -6 and add it to the 8 and you get x = 14 still not our answer so thats also ruled out. Then x-8=6 is the same thing as the last one but with a -8 instead of a 6 but you get the same answer which is x=14 so not that one either. Then you work on the choice x+8=6 and you subtract 8 from both sides and you end up with a -2. So our final answer is C: X+8=6

The actual distance between City C and City D is 4,224,000 feet.
What is total distance?
Whole distance refers to the actual travel distance between the origin and destination locations of the item.
We can use the given scale to convert the distance between City A and City B to feet:
500 miles = 500 * 5280 feet = 2,640,000 feet
Since 1.6 feet represents this distance on the wall map, we have:
1.6 feet = 2,640,000 feet / x

A mall charges a parking fee of
P35.00 for the first two hours and an
extra P15.00 for each hour (or a
fraction of it) after that. If you park
for more than twelve hours, you
instead pay a flat rate of P250.00.
Represent your parking fee using the
function p(t) where t is the number
of hours you parked in the mall.
p(t) = {
P35.00 if t ≤ 2
P35.00 + P15.00 × (t - 2) if 2 < t ≤ 12
P250.00 if t > 12
} is the required function to represent given information.
What is expression ?Expressions are commonly used in programming to perform calculations, manipulate data, and make decisions based on the results of evaluations.
According to given conditions:To represent the parking fee using the function p(t), we need to consider the different rates depending on the number of hours parked. Here are the different cases we need to consider:
If t ≤ 2, the parking fee is P35.00
If 2 < t ≤ 12, the parking fee is P35.00 plus P15.00 for each hour (or fraction of it) after the first two hours. This can be represented by the equation:
p(t) = P35.00 + P15.00 × (t - 2)
If t > 12, the parking fee is a flat rate of P250.00.
We can combine these cases into a single function using a piecewise function. Here is the function p(t):
p(t) = {
P35.00 if t ≤ 2
P35.00 + P15.00 × (t - 2) if 2 < t ≤ 12
P250.00 if t > 12
}
This function represents the parking fee in terms of the number of hours parked (t). To use it, simply substitute the number of hours parked into the function and calculate the resulting fee. For example, if you parked for 4 hours, the fee would be:
p(4) = P35.00 + P15.00 × (4 - 2) = P65.00
Therefore, p(t) = {
P35.00 if t ≤ 2
P35.00 + P15.00 × (t - 2) if 2 < t ≤ 12
P250.00 if t > 12

Lewis wants to buy a skateboard that costs $89.99. He has $300 saved. He wants to save $11 each week until he has enough money to pay for the skateboard. The inequality 30 + 11w ≥ 89.99 represents this situation, where w is the least number of weeks Lewis has to save until he has enough money to pay for the skateboard?
Answer:
Step-by-step explanation:
I'm guessing you meant to say Lewis had $30 starting.
Well since we have an inequality already, that saves time on me and I can show you how to solve!
[tex]30+11w\geq 89.99[/tex]
[tex]11w\geq59.99[/tex]
[tex]w\geq 5.4536[/tex]
If Lewis waited 5 weeks, he'd only have 85, so we need to round up to 6 weeks, where he'd have $96. Hope this helps!

Split into a sum of two rational expressions with unlike denominators: (2x+3)/(x^(2)+3x+2)
The sum of two rational expressions with unlike denominators is 1/(x+1) + 1/(x+2).
To split the given rational expression into a sum of two rational expressions with unlike denominators, we will use the partial fraction decomposition method. Here are the steps:
1. Factor the denominator of the given rational expression: (x^(2)+3x+2) = (x+1)(x+2)
2. Set up the partial fraction decomposition: (2x+3)/(x+1)(x+2) = A/(x+1) + B/(x+2)
3. Multiply both sides of the equation by the common denominator to get rid of the denominators: 2x+3 = A(x+2) + B(x+1)
4. Set up a system of equations by equating the coefficients of the like terms: 2x+3 = (A+B)x + (2A+B)
5. Solve the system of equations to find the values of A and B: A=1, B=1
6. Substitute the values of A and B back into the partial fraction decomposition: (2x+3)/(x+1)(x+2) = 1/(x+1) + 1/(x+2)
Therefore, the sum of two rational expressions with unlike denominators is 1/(x+1) + 1/(x+2).

Answer fast!!!! Please!!!!!
According to the information, ball B is the one that reaches the highest height because after 1.5 seconds it has a height of 13m, while ball A has a height of 12m.
How to identify the ball that reaches higher?To identify the ball that reaches the highest we must solve the function shown. Additionally, to know what is the greatest height we must replace the value of x by 1.5 as shown below:
f(x) = -4.9x² + 14.7x + 0.975f(x) = -4.9 * 1.5² + 14.7 * 1.5 + 0.975f(x) = -4.9 * 2.25 + 22.05 + 0.975f(x) = -11.025 + 22.05 + 0.975f(x) = 12According to the above we can infer that this function gives a height less than the one shown in the table because the height of the ball is 12 and that of the table is 13. So 12 < 13.
