g(x) = { 1₁ -1 - T≤x≤0 осхь п 1 f(x+2TT) = g(x)
The coefficient for the interval -T ≤ x ≤ 0 in the function g(x) is 1. However, the coefficient for the interval 0 ≤ x ≤ 2π depends on the specific form of the function f(x). Without additional information about f(x), we cannot determine its coefficient for that interval.
To solve for the coefficients in the function g(x), we need to consider the conditions given:
g(x) = { 1, -1, -T ≤ x ≤ 0
{ 1, f(x + 2π) = g(x)
We have two pieces to the function g(x), one for the interval -T ≤ x ≤ 0 and another for the interval 0 ≤ x ≤ 2π.
For the interval -T ≤ x ≤ 0, we are given that g(x) = 1, so the coefficient for this interval is 1.
For the interval 0 ≤ x ≤ 2π, we are given that f(x + 2π) = g(x). This means that the function g(x) is equal to the function f(x) shifted by 2π. Since f(x) is not specified, we cannot determine the coefficient for this interval without additional information about f(x).
The coefficient for the interval -T ≤ x ≤ 0 is 1, but the coefficient for the interval 0 ≤ x ≤ 2π depends on the specific form of the function f(x).

In the equation 2y=18, determine which property of equality will be used to isolate the variable. Choose the best answer. A. Multiplication Property of Equality B, Addition Property of Equality C. Division Property of Equality D. Subtraction Property of Equality
Answer:
(C) Division Property of Equality
Step-by-step explanation:
Looking at the equation \(2y=18\), we see that if we want to isolate y, we need to divide it by 2 - because we're multiplying it by 2, and 2 times a number divided by 2 is just the number.
The Division Property of Equality states that if we have an equation, \(a=b\), then \(a\div c = b\div c\).
So, that means \(2y\div 2\) will be equal to \(18 \div 2\), which is 9.
Hope this helped!
Answer:
C. Division Property of Equality
Step-by-step explanation:
The equation is
2y = 18
The answer is of the form
y = a number
Now, we have 2y. We want y alone. 2y means 2 multiplied by y. Since we want y alone, to undo the multiplication of 2 and y, we need to use division. We need to divide 2y by 2. Then we also need to divide the right side by 2. Since we are using division, the answer is:

Exercise 1. Two servers (S. and Ss) with exponential service time and same service rate are busy completing service of two jobs at time t = 0. The server that completes service first is referred to as the winning server (Sw), the other is referred to as the losing server (St). Jobs must complete their service before departing from the queue. A) Compute the probability of S to be the winning server, i.e., P(S = S1) = P(S = S2). Compute the probability of S, to be the winning server, i.e., P(S = Sx) = P(S = Si) (pt. 10). B) Compute the expected departure time of the winning server, defined as ty > 0 [pt. 10). C) Compute the expected departure time of the losing server, defined as t > t pt. 10).
A) Here, we have two servers: Server 1 (S1) and Server 2 (S2). And we need to compute the probability of S to be the winning server, i.e., P(S = S1) = P(S = S2).Since we have two servers with the same service rate, the jobs have equal chances of being assigned to either server.
Therefore, P(S = S1) = P(S = S2)
= 1/2.
(Both servers have equal probabilities of winning).
B) Expected departure time of the winning server, defined as ty > 0. It is also called the mean service time (MST) or the expected value of the service time. The expected value of an exponential distribution is equal to the reciprocal of the service rate. Thus, if the service rate of both servers is μ, then the expected departure time of the winning server will be 1/μ.
C) Expected departure time of the losing server, defined as t > t0. Since the two jobs can't leave until their services are complete, the service time of the winning server will be the total time taken by both jobs. Thus, the expected departure time of the losing server can be calculated by taking the expected departure time of the winning server (which is 1/μ) and subtracting the mean service time (MST) of a single job, which is 1/2μ. Therefore, the expected departure time of the losing server will be 1/μ - 1/2μ = 1/2μ.

14 less than 8 times a number is 3 more than 4 times the number. What is the number?
Answer:
x = 17/4
Step-by-step explanation:
Let x = the number
8x-14 = 4x+3
Subtract 4x from each side
8x -14-4x = 4x+3-4x
4x-14 = 3
Add 14 to each side
4x-14+14 = 3+14
4x = 17
Divide by 4
4x/4 = 17/4
x = 17/4
observe that the column is the sum of the and columns. find a nontrivial solution of without performing row operations
To find a nontrivial solution of a system of equations without performing row operations is to recognize that the column on the left side is the sum of the and columns.
To find a nontrivial solution of a system of equations, we can observe the relationship between the columns in the augmented matrix representing the system. If the column on the left side is the sum of the and columns, then there exists a nontrivial solution. Let's consider a system of equations with variables x, y, and z. The augmented matrix representing the system can be written as [A|B], where A represents the coefficients of the variables and B represents the constant terms.
If we notice that the column on the left side is the sum of the and columns, i.e., the sum of the first and second columns equals the third column, then we can conclude that the system of equations has a nontrivial solution. This means that there are infinitely many solutions to the system, rather than a unique solution. By recognizing this relationship, we can determine that the system is dependent, and we can find a nontrivial solution by setting one of the variables as a free variable and expressing the other variables in terms of it. This allows us to generate a solution set that satisfies the system of equations without performing row operations.

A company pays sales staff a monthly commission of:4% on the first $15,000 of sales6% on the next $20,000 of sales7.5% on all sales above $35,000What amount would Tony earn if his sales for a month were $41,000?
Answer
Tony's Commission for the month where his sales was $41,000 is
= $2,250
Explanation
4% on the first $15,000 of sales
6% on the next $20,000 of sales
7.5% on all sales above $35,000
So, if the sales in a month is $41,000, there will be
4% on the first $15,000 of sales
6% on the next $20,000 of sales
7.5% of the remaining $6,000
Tony's Commission = (4% × 15,000) + (6% × 20,000) + (7.5% × 6,000)
= (0.04 × 15,000) + (0.06 × 20,000) + (0.075 × 6,000)

right rectangular prism calc: find w, l=n/a, h=n/a, v=n/a
The value of width 'w' of rectangular prism with l = n/a, h = n/a, v = n/a is given by, w = a/n.
We know that the volume of rectangular prism with length L and width W and Height H is given by,
V = L*W*H
Given that the Height of the rectangular prism, h = n/a
Length of the rectangular prism, l = n/a
Volume of the rectangular prism, v = n/a
let the width of the rectangular prism be 'w'.
So from the volume formula we get,
v = lwh
n/a = (n/a)*w*(n/a)
n/a = (n/a)²*w
w = (n/a)/(n/a)² = (n/a)*(a/n)² = a/n

What is the formula to find centre?
The general equation to find centre of a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius.
Centre of the CircleThe location of a moving point on a plane such that its separation from a stationary point on the plane remains constant or fixed is described as a circle. The centre of the circle is the name given to the fixed point
A circle's centre and radius make up its 2D shape. Knowing the circle's centre and radius allows us to draw any circle. The number of radii that a circle can have is unlimited. The intersection of all the radii constitutes the centre of a circle. It is also known as the centre of the circle's diameter.
Center of Circle FormulaThe general equation of a circle is another name for the centre of circle formula. If the radius is r, the center's coordinates are (h,k), and any point on the circle is (x,y), the centre of the circle formula is as follows:
(x - h)2 + (y - k)2 = r2
