graph the linear function. g(x)=2/5x-3
It is known that 2x-3/x = x + 1 What is the value of x^2 -x + 3
The value of the equation x² - x + 3 is 37/9.
We have,
We can start by multiplying both sides of the equation by x:
2x - 3/x = x + 1
2x - 3 = x^2 + x
Rearranging and simplifying, we get:
x^2 - x + 3 = (2x - 3) + x^2
x^2 - x + 3 = x^2 + 2x - 3
-x + 3 = 2x - 3
5 = 3x
x = 5/3
Now we can substitute x into the equation x^2 - x + 3:
x^2 - x + 3 = (5/3)^2 - 5/3 + 3
x^2 - x + 3 = 25/9 - 15/9 + 27/9
x^2 - x + 3 = 37/9
Therefore,
The value of x² - x + 3 is 37/9.

For the following question, show representation, your initial equations, your algebra work, symbolic answer, and units check.
A dog is sitting at an initial position of D1= (50 m North, 10 m East) from her home. She moves in a straight line until she is at a final position of D2 = ( 5 m North, 35 m East) from her home. It takes her 15 seconds to move from the initial position to the final position; find the magnitude of her average velocity vector.
The magnitude of the average velocity vector is approximately 3.651 m/s.
To find the magnitude of the average velocity vector, we need to calculate the displacement and divide it by the time taken.
Representation:
Initial position: D1 = (50 m North, 10 m East)
Final position: D2 = (5 m North, 35 m East)
Time taken: t = 15 seconds
Equations:
Displacement vector (ΔD) = D2 - D1
Average velocity vector (\(V_{avg}\)) = ΔD / t
Algebra work:
ΔD = D2 - D1
= (5 m North, 35 m East) - (50 m North, 10 m East)
= (-45 m North, 25 m East)
|ΔD| = √((-45)^2 + 25^2) [Magnitude of the displacement vector]
\(V_{avg}\) = ΔD / t
= (-45 m North, 25 m East) / 15 s
= (-3 m/s North, 5/3 m/s East)
|\(V_{avg}\)| = √((-3)^2 + (5/3)^2) [Magnitude of the average velocity vector]
Symbolic answer:
The magnitude of the average velocity vector is approximately 3.651 m/s.
Units check:
The units for displacement are in meters (m) and time in seconds (s). The average velocity is therefore in meters per second (m/s), which confirms the units are consistent with the calculation.
Therefore, the magnitude of the average velocity vector is approximately 3.651 m/s.

If required, round your answers to two decimal places.
Mean = ________
Median = _________
Mode = _________
The mode of the given data values is N/A (not applicable).Hence, the mean, median, and mode of the given data values are:Mean = 54.36Median = 55.5Mode = N/A (not applicable)
Given data values are 55, 56, 70, 61, 53, 57, 50, 73, 52, 69, and 2. We need to calculate the mean, median, and mode of this sample.So, let's first arrange the data values in ascending order:2, 50, 52, 53, 55, 56, 57, 61, 69, 70, 73
Mean:The mean is the sum of all the data values divided by the total number of data values. So, we can use the following formula to calculate the mean:
Mean = (sum of all the data values) / (total number of data values)Sum of all the data values = 55 + 56 + 70 + 61 + 53 + 57 + 50 + 73 + 52 + 69 + 2 = 598Total number of data values = 11
Therefore,Mean = (sum of all the data values) / (total number of data values) = 598 / 11 = 54.36 (rounded to two decimal places)Therefore, the mean of the given data values is 54.36.
Median:The median is the middle value of a sorted data set. Since the data set has 11 data values, the median is the average of the 6th and 7th values (counting from smallest to largest).
Therefore, the median is :Median = (55 + 56) / 2 = 55.5Therefore, the median of the given data values is 55.5.
Mode:The mode is the data value that appears most frequently in the data set. In this case, there is no data value that appears more than once. So, there is no mode.
Therefore, the mode of the given data values is N/A (not applicable).Hence, the mean, median, and mode of the given data values are:Mean = 54.36Median = 55.5Mode = N/A (not applicable)

The value of a motorcycle depreciates at the rate of 5% per year. If its present value is * 45,000, what will be the value after 2 years?
Answer:
40612.50
Step-by-step explanation:
First you work out the percentage decrease:
100 - 5 = 95
95/100 = 0.95 (/ means divide)
Then you work out the amount decrease:
Long Method
45000 x 0.95 = 42750
42750 x 0.95 = 40612.50
or Short Method
45000 x 0.95² = 40612.50
Solve the differential equations 2xy(dy/dx)=1 y^2. y(2)=3
The solution to the given differential equation 2xy(dy/dx) = y², with the initial condition y(2) = 3, is y = (27 * e⁽ˣ⁻²⁾\()^{1/4}\).
To solve the given differential equation
2xy(dy/dx) = y²
We will use separation of variables and integrate to find the solution.
Start with the given equation
2xy(dy/dx) = y²
Divide both sides by y²:
(2x/y) dy = dx
Integrate both sides:
∫(2x/y) dy = ∫dx
Integrating the left side requires a substitution. Let u = y², then du = 2y dy:
∫(2x/u) du = ∫dx
2∫(x/u) du = ∫dx
2 ln|u| = x + C
Replacing u with y²:
2 ln|y²| = x + C
Using the properties of logarithms:
ln|y⁴| = x + C
Exponentiating both sides:
|y⁴| = \(e^{x + C}\)
Since the absolute value is taken, we can remove it and incorporate the constant of integration
y⁴ = \(e^{x + C}\)
Simplifying, let A = \(e^C:\)
y^4 = A * eˣ
Taking the fourth root of both sides:
y = (A * eˣ\()^{1/4}\)
Now we can incorporate the initial condition y(2) = 3
3 = (A * e²\()^{1/4}\)
Cubing both sides:
27 = A * e²
Solving for A:
A = 27 / e²
Finally, substituting A back into the solution
y = ((27 / e²) * eˣ\()^{1/4}\)
Simplifying further
y = (27 * e⁽ˣ⁻²⁾\()^{1/4}\)
Therefore, the solution to the given differential equation with the initial condition y(2) = 3 is
y = (27 * e⁽ˣ⁻²⁾\()^{1/4}\)

The ball will hit the ground after 4 seconds (x2 = 4).
How to solveGiven the formula h(x) = -16x^2 + v0x + h0, we can plug in the values for the initial velocity (v0) and the initial height (h0) to find the equation that describes the ball's height as a function of time.
v0 = 64 ft/s (initial velocity)
h0 = 12 ft (initial height)
Now, we can write the function for the ball's height:
h(x) = -16x^2 + 64x + 12
To find when the ball hits the ground, we need to solve for x when h(x) = 0:
0 = -16x^2 + 64x + 12
This is a quadratic equation, and we can solve it using the quadratic formula:
x = (-b ± √(b^2 - 4ac)) / 2a
In this case, a = -16, b = 64, and c = 12.
x = (-64 ± √(64^2 - 4*(-16)12)) / 2(-16)
First, we find the discriminant (b^2 - 4ac):
64^2 - 4*(-16)*12 = 4096 + 768 = 4864
Now we can plug the discriminant back into the quadratic formula:
x = (-64 ± √4864) / (-32)
We have two possible solutions:
x1 = (-64 + √4864) / (-32)
x1 = (-64 + 64) / (-32)
x1 = 0
x2 = (-64 - √4864) / (-32)
x2 = (-64 - 64) / (-32)
x2 = 128 / 32
x2 = 4
Since x1 = 0 represents the initial time when the ball is kicked, we discard this solution.
Therefore, the ball will hit the ground after 4 seconds (x2 = 4).

turnover at retail. Round to the nearest tenth.
2.1
1.9
1.6
1.3
Answer:
1.6
Step-by-step explanation:
The stock turnover at retail is a measure of how many times a business sells its average inventory during a period of time. We can calculate the stock turnover by dividing the retail sales by the average inventory.
Stock turnover = Retail Sales / Average Inventory
Given the values :
Average Inventory = $123,456Retail Sales = $196,450Substituting these values
Stock turnover at retail = 196,450 / 123,456 = 1.6 (rounded to the nearest tenth)
Scores on an English test are normally distributed with a mean of 37.6 and a standard deviation of 7.6. Find the score that separates the top 59% from the bottom 41% Group of answer choices 35.9 39.3 42.1 33.1
The score that separates the top 59% from the bottom 41% is 39.3.
To solve this problem, we need to find the z-score that separates the top 59% from the bottom 41%, and then use the z-score formula to find the corresponding raw score.
The z-score for the top 59% is the z-score that corresponds to a cumulative area of 0.59 to the left of it. We can find this using a standard normal table or a calculator:
z = invNorm(0.59) = 0.24
The z-score for the bottom 41% is the z-score that corresponds to a cumulative area of 0.41 to the left of it:
z = invNorm(0.41) = -0.24
The score that separates these two z-scores can be found using the z-score formula:
z = (x - μ) / σ
where x is the raw score, μ is the mean, and σ is the standard deviation. Solving for x, we get:
x = z * σ + μ
Plugging in the values we found earlier, we get:
x = 0.24 * 7.6 + 37.6 = 39.3
Therefore, the score that separates the top 59% from the bottom 41% is 39.3.
