Michael Phelps has been working on improving his time in the 500 yard freestyle competition.His first time was 4 minutes and 25 seconds. He improved his time by 13 seconds. The next timehe swam, he improved his time by 16 seconds. At the competition, he got his best time when heimproved by 8 more seconds. What was Michael's best swimming time?
Initial time = 4 minutes and 25 seconds
first improve = 13 seconds
second improve = 16 seconds
third improve = 8 seconds
First, we have to add all the improvements:
13+16+8 = 37 seconds
Then we have to subtract the result to the initial time:
4m 25 sec -37 sec =
Since 1 minute = 60 seconds
4 minutes x 60 = 240 seconds
240 + 25 sec = 265 seconds
4m 25 sec = 265 seconds
Back with the subtraction:
265 sec-37 sec = 228 seconds
Michaels best swimming time was 228 seconds.
To convert it into minutes:
228 /60 = 3.8 minutes

4
equal pieces.
Which equation shows how to find the length of each piece?
The equation shows how to find the length of each piece is L = R / N and the length of each piece is 1.5 feet.
To find the length of each piece, we can use the following equation:
Length of each piece = Total length of the ribbon / Number of pieces
In mathematical terms, we can represent this equation as:
L = R / N
Where,
L is the length of each piece
R is the total length of the ribbon (66 feet in this case)
N is the number of pieces (44 in this case)
In this problem, we are given a 66-foot ribbon and we are asked to cut it into 44 equal pieces. We need to find out the length of each piece.
Using this equation, we can easily find the length of each piece:
L = 66 / 44
L = 1.5 feet
Therefore, each piece of the ribbon is 1.5 feet long.

In a linear programming problem, the binding constraints for the optimal solution are
5X + 3Y ≤
30
2X + 5Y ≤
20
a. As long as the slope of the objective function stays between .......... and ............, the current optimal solution point will remain optimal.
b.Which of these objective functions will lead to the same optimal solution? 1) 2X + 1Y 2) 7X + 8Y 3) 80X + 60Y 4) 25X + 35Y
a) As long as the slope of the objective function stays between -8/7 and -1/2 the current optimal solution point will remain optimal.
b) The objective functions that lead to the same optimal solution are Z = 2X + Y and Z = 25X + 35Y.
a. The binding constraints for the given linear programming problem are 5X + 3Y ≤ 30 and 2X + 5Y ≤ 20. We need to find the range of slope of the objective function for which the current optimal solution point will remain optimal.
First, we graph the two binding constraints on the X-Y plane and find their intersection point as (X, Y) = (3, 3). This is the current optimal solution point.
Next, we need to check the slope of the objective function at this point. Let the objective function be Z = aX + bY. At the optimal solution point, the slope of the objective function is given by -b/a.
For the current optimal solution point (3, 3), we can compute the slope of the objective function for different values of a and b as follows:
When a = 2 and b = 1, the slope of the objective function is -1/2.
When a = 7 and b = 8, the slope of the objective function is -8/7.
When a = 80 and b = 60, the slope of the objective function is -3/4.
When a = 25 and b = 35, the slope of the objective function is -7/5.
Since the binding constraints have negative slopes, we know that the objective function must have a negative slope for an optimal solution to exist. Therefore, the range of slope of the objective function for which the current optimal solution point will remain optimal is between -8/7 and -1/2.
b. To find the objective functions that lead to the same optimal solution, we need to find the objective functions that have the same slope at the current optimal solution point (3, 3). We can compute the slope of each objective function as follows:
For Z = 2X + Y, the slope at (3, 3) is -1/2.
For Z = 7X + 8Y, the slope at (3, 3) is -8/7.
For Z = 80X + 60Y, the slope at (3, 3) is -3/4.
For Z = 25X + 35Y, the slope at (3, 3) is -7/5.
Therefore, the objective functions that lead to the same optimal solution are Z = 2X + Y and Z = 25X + 35Y

Solve the system of equations using the substitution method (solving for x and y intercepts). Please give graphing points.
x+y=5
2x-y=-2
WILL GIVE BRAINLIEST
Answer:
(x, y) = (1, 4)
Step-by-step explanation:
Given: x+y=5 and 2x-y=-2
Solve for y and x
x+y=5; solve for y
y = 5 - x; substitute into other equation
2x-y= -2
2x - (5 - x) = -2
2x - 5 + x = -2; combine x's
3x - 5 = -2; add 5 to both sides
3x =3; divide by 3
x = 1; use this to solve for y
x+y=5
1 + y = 5; subtract 1 from both sides
y = 4
(x, y) = (1, 4)

The equation in point-slope form is:
\(y=mx+b\)where m is the slope and b is the y-intercept.
We are told the slope of this line. Then, we can replace this value in the equation as follows:
\(y=-\frac{5}{4}x+b\)As we have one point (x, y) that passes through this line, we can replace it in the x and y values and solve for b as follows:
\(-9=-\frac{5}{4}\times4+b\)Simplifying:

\(y=-\frac{5}{4}x-4\)
find the matrix a' for t relative to the basis b'. t: r2 → r2, t(x, y) = (−8x y, 8x − y), b' = {(1, −1), (−1, 5)}
The matrix of \(t\) relative to the basis \(b'\) is \(A' = \begin{bmatrix} -9 & 7 \\ -37 & 43 \end{bmatrix}\).
\(\textbf{To find the matrix of } t \textbf{ relative to the basis } b', \textbf{we have to follow some steps. The steps are described below:}\)
First, we have to find the images of basis vectors under the transformation \(t\). \(t(-1,1) = (-9,7)\) and \(t(1,-5) = (-37,43)\).
Represent the image vectors of the basis in the standard basis. We use these vectors as columns in the matrix of \(t\) in the basis \(b'\).
\((-9,7) = -9(1,0) + 7(0,1) = (-9,7) = -9(-1,1) + 7(1,-5)\)
\((-37,43) = -37(1,0) + 43(0,1) = (-37,43) = -37(-1,1) + 43(1,-5)\)
Hence, we can write the following equation: \(A[x]_{b'} = [x]_S\)
Where \(A[x]_{b'}\) is the main answer in the form of a matrix, and \([x]_S\) is the coordinate of \([x]_{b'}\) with respect to the standard basis.
Now, we will write the equations with the coordinates of the basis vectors of \(b'\).
\(A[1,0] = [-9, -37]\) and \(A[0,1] = [7, 43]\)
Now we will write the matrix of \(A\) as follows:
\(A = \begin{bmatrix} -9 & 7 \\ -37 & 43 \end{bmatrix}\)
Thus, the matrix of \(t\) relative to the basis \(b'\) is \(A' = \begin{bmatrix} -9 & 7 \\ -37 & 43 \end{bmatrix}\).

Use exponential smoothing with alpha (α) = 0.35 and an initial forecast of 417 along with seasonality to calculate the Year 4, Q1 forecast.
The Year 4, Q1 forecast using exponential smoothing with α = 0.35 and an initial forecast of 417, along with seasonality, is 335.88.
Exponential smoothing is a forecasting technique that takes into account both the historical demand and the trend of the data. It is calculated using the formula:
Forecast = α * (Demand / Seasonal Index) + (1 - α) * Previous Forecast
Initial forecast (Previous Forecast) = 417
α (Smoothing parameter) = 0.35
Demand for Year 4, Q1 = 307
Seasonal Index for Q1 = 0.762
Using the formula, we can calculate the Year 4, Q1 forecast:
Forecast = 0.35 * (307 / 0.762) + (1 - 0.35) * 417
= 335.88
Therefore, the Year 4, Q1 forecast using exponential smoothing with α = 0.35 and an initial forecast of 417, along with seasonality, is 335.88.
The forecasted demand for Year 4, Q1 using exponential smoothing is 335.88.

For the rectangle JKLM has diagonals intersecting at P and if m∠LJK = 35°, then
m∠LJM = 110°,
m∠JPK = 17.5°,
m∠JPM = 52.5°.
Solution:
The statement is "Rectangle JKLM has diagonals intersecting at P."
We need to find the angles in this rectangle.
First, we need to draw the rectangle JKLM and intersecting diagonals.
Then, we have to analyze the angles:
Since JKL and KML are right angles, they are 90°.
Let's look at angle LJK, which is given in the question as 35°.
To find m∠LJM, we have to look at the opposite angle MJK, which is also 35° (because rectangle).
Therefore,
m∠LJM = 180 - 35 - 35
= 110°.
Now, we have to look at triangle JKP and find m∠JPK:
Since the diagonals bisect each other, angle JPK is half of the angle LJK, so
m∠JPK=35/2
= 17.5°.
Finally, we have to find m∠JPM:
We know that JPK is 17.5°, and we found that LJM is 110°.
Since they form a linear pair,
m∠JPM = 180 - 17.5 - 110
= 52.5°.
Hence, m∠LJM = 110°, m∠JPK = 17.5°, and m∠JPM = 52.5°.
