How many solutions does the equation 4p 7 = 3 4 4p have? one two infinitely many none
Answers
Answer:
one
Step-by-step explanation:
The equation 4p + 7 = 3(4p) can be simplified by distributing the 3 on the right-hand side of the equation:
4p + 7 = 12p
Subtracting 4p from both sides of the equation, we get:
7 = 8p
Dividing both sides of the equation by 8, we get:
p = 7/8
Therefore, the equation has only one solution, which is p = 7/8. Answer: one.

Plot the graph of the given equation: y=3x+1
Answers
Answer: used plot graph
Step-by-step explanation: sourced it with plot
The way to plot the graph is to find both x-intercept and y-intercept. (Unless if it's a polynomial function which you need to find vertexes. But this one is linear so no vertex.)
(1) - Find x-intercept, substitute y = 0
\(y=3x+1\\0=3x+1\\-1=3x\\3x=-1\\x=-\frac{1}{3}\)
Therefore, the graph intercepts x-axis at (-1/3, 0)
(2) - Find y-intercept, substitute x = 0
\(y=3x+1\\y=0+1\\y=1\)
Therefore, the graph intercepts y-axis at (0,1)

what value will the monthly seasonal indexes (created for the 12 months of the year) add up to?
Answers
The monthly seasonal indexes (created for the 12 months of the year) will add up to a value of 12. This is because seasonal indexes are created to measure the changes in demand for a product or service over the course of a year.
Each month is assigned a value that reflects the demand for that month in relation to the average demand for the entire year.
The sum of these values for all 12 months should equal 12, as this represents the total demand for the year. Therefore, the value of the monthly seasonal indexes will add up to 12.

Answers
When solving proportions, we set the cross products equal, and then we solve for the unknown variable.
When solving proportions, we set the cross products equal to each other and then proceed to solve for the unknown variable. A proportion is an equation that states that two ratios or fractions are equal. To solve a proportion, we first identify the two ratios involved and set their cross-products equal.
For example, consider the proportion: a/b = c/d
To solve for the unknown variable, we set the cross products (a * d) and (b * c) equal:
a * d = b * c
This equation allows us to find the value of the unknown variable by manipulating the equation through multiplication or division to isolate the variable on one side of the equation.
By setting the cross products equal, we essentially establish an equality between the two ratios, indicating that the fractions on either side of the proportion are equivalent. Solving for the unknown variable allows us to determine its value based on the relationship between the given ratios.

Determine if the equation y = 2/5 x − 4 y=25x-4 represents a proportional relationship. If so, determine the constant of proportionality.
Answers
Answer:
The linear equation represents a proportional relationship and its constant of proportionality is \(k = \frac{2}{5}\).
Step-by-step explanation:
A proportional relationship exists when the following relationship is observed:
\(u = k\cdot v\)
Where:
\(u\) - Dependent variable.
\(v\) - Independent variable.
\(k\) - Proportionality constant.
If \(y =\frac{2}{5}\cdot x - 4\) and \(v = x\) and \(u = y+4\), the following expresion is found:
\(y = \frac{2}{5}\cdot x -4\)
\(y + 4 = \frac{2}{5}\cdot x\)
\(u = \frac{2}{5}\cdot v\)

A circle has a circumference of 20π meters. If a sector has a central angle of 45°, what is the arc length of the sector? Use pi = 3.14
Answers
the arc length of the sector is 7.85 meters.
Define circumferenceThe circumference is define for a circle is given by the formula:
C = 2πr
where C is the circumference, π is the value of pi, and r is the radius of the circle.
In this case, the circumference of the circle is given as 20π meters. So we can write:
20π = 2πr
Dividing both sides by 2π, we get:
r = 10 meters
The arc length of a sector of a circle with central angle θ and radius r is given by the formula:
Arc length = (θ/360°) x 2πr
where θ is the central angle in degrees.
In this case, the central angle of the sector is 45°, and the radius of the circle is 10 meters. So we can substitute these values into the formula:
Arc length = (45/360) x 2π(10) = (1/8) x 20π = 2.5π
Using the value of pi as 3.14, we can calculate the arc length as:
2.5π = 2.5 x 3.14 = 7.85 meters
Therefore, the arc length of the sector is 7.85 meters.

Area of the square figure is equal to the square of one of its sides. The difference in the length of the two tiles is 0.4 meters.
What is the area of the square?The area of the square figure is equal to the square of one of its sides.
Area of the square Tiles = (length of one side)²
We know that the area of a square is the square of one of its lengths, therefore, the length of each of the square tiles can be written as,
Area of the square Tiles = (length of one side)²
Length of the Tile A
Area of the square Tiles = (length of one side)²
√(Area of the square Tiles) = length of one side
Since, Area of the square tiles A is 20
Thus,
Length of tile A = √20 = 4.5 inches Approx.
Length of Tile B
Area of the square Tiles = (length of one side)²
√(Area of the square Tiles) = length of one side
Since, Area of the square tiles B is 20
Thus,
Length of tile B = √24 = 4.9 inches Approx.
Thus, the difference between the length of the two tiles can be written as,
Difference = 4.9 - 4.5
Difference = 0.4 inches
Hence, the difference in the length of the two tiles is 0.4 meters.

A particle moves along the y-axis so that at time t≥0 its position is given by y(t)=t3−6t2+9t. Over the time interval 0
Answers
Therefore, the maximum displacement of the particle is 4 units, and it occurs at time t = 1.
To find the maximum displacement, we need to first determine the particle's velocity and acceleration.
The velocity of the particle is given by the derivative of its position function:
\(v(t) = y'(t) = 3t^2 - 12t + 9\)
The acceleration of the particle is given by the derivative of its velocity function: a(t) = v'(t) = 6t - 12
Now, to find the maximum displacement, we need to find the time at which the particle comes to rest.
This occurs when its velocity is zero:
\(3t^2 - 12t + 9 = 0\)
Simplifying this equation, we get:
\(t^2 - 4t + 3 = 0\)
This quadratic equation factors as:
(t - 1)(t - 3) = 0
So the particle comes to rest at t = 1 or t = 3.
Next, we need to determine whether the particle is at a maximum or minimum at each of these times.
To do this, we look at the sign of the acceleration:
When t = 1, a(1) = 6(1) - 12 = -6, which is negative.
Therefore, the particle is at a maximum at t = 1.
When t = 3, a(3) = 6(3) - 12 = 6, which is positive.
Therefore, the particle is at a minimum at t = 3.
Finally, we need to find the displacement of the particle at each of these times:
\(y(1) = 1^3 - 6(1)^2 + 9(1) = 4\)
\(y(3) = 3^3 - 6(3)^2 + 9(3) = 0.\)

Answers
The actual distance between Beitbridge and Musina is 3,900,000 kilometers.
To calculate the actual distance between Beitbridge and Musina, given the scale of the map and the measured distance on the map, we can use the concept of scale.
The scale of the map is given as 1:3,000,000, which means that 1 cm on the map represents 3,000,000 cm in real life.
The measured distance on the map between Beitbridge and Musina is 1.3 cm.
To find the actual distance, we can set up a proportion using the scale:
1 cm on the map / 3,000,000 cm in real life = 1.3 cm on the map / x km in real life.
Simplifying the proportion, we have:
1 / 3,000,000 = 1.3 / x.
Cross-multiplying, we get:
x = (1.3 * 3,000,000) / 1.
x = 3,900,000 / 1.
x = 3,900,000 km.
The actual distance between Beitbridge and Musina is 3,900,000 kilometers.

When doing a pull-up, a physics student lifts her 42 kg body to a distance of 0.25 m in 2 seconds. What is the power delivered by the student's biceps?
Answers
The power delivered by the student's biceps is 51.45 watts (W).
To calculate the power delivered by the student's biceps while doing a pull-up, we use the formula:
Power = Work/Time
Since the physics student lifts her 42 kg body to a distance of 0.25 m, the work done is given by:
Work = Force x Distance
The force exerted by the student is equal to her weight, which is given by:
F = mg
where m = 42 kg (mass of the student) and
g = 9.8 m/s² (acceleration due to gravity)
Therefore,
F = 42 kg x 9.8 m/s²
= 411.6 N (weight of the student)
Hence, the work done by the student is:
Work = Force x Distance
= 411.6 N x 0.25 m
= 102.9 J (joules)
The time taken by the student to complete the pull-up is given as 2 seconds.
Therefore:Time = 2 s
Now we can substitute the values into the formula for power:

The margin of error for the 90% confidence interval is 5.84
To find the margin of error for a 90% confidence interval, we will use the given information and the z-score table provided.
1. Identify the z-score for a 90% confidence level: Since the confidence level is 90%, there is 10% left in the tails. Divide this by 2 to find the area in each tail, which is 5%. Look for the z-score associated with 0.05 in the table provided. The z-score is 1.645.
2. Find the standard error: The standard error is calculated as the population standard deviation (σ) divided by the square root of the sample size (n). In this case, σ = 21 and n = 35.
Standard Error (SE) = σ / √n = 21 / √35 ≈ 3.55
3. Calculate the margin of error: The margin of error (ME) is calculated by multiplying the z-score by the standard error.
ME = z-score * SE = 1.645 * 3.55 ≈ 5.84
