The price that yields maximum revenue is equal to $99. Also, the maximum revenue is equal to $490,050.
How to determine the unit price that yields a maximum revenue?In order to determine the price that would yield the maximum revenue, we have to find the derivative of the revenue function R(p) by applying the Power Rule.
Mathematically, the revenue function, R(p) is given by this mathematical expression:
Revenue function, R(p) = NP
Where:
N represents the number of customersP represents the monthly price of the subscriptionLet the variable n represent the number of reductions in the price. Therefore, we have:
N = 3,400 + 50n ....equation 1.
P = 130 - n
n = 130 - P
From equation 1, we have:
N = 3,400 + 50(130 - P)
N = 3,400 + 6,500 - 50P
Next, we would re-write the revenue function R(p) as follows:
Revenue function, R(p) = (3,400 + 6,500 - 50P)P
Revenue function, R(p) = 3,400P + 6,500P - 50P²
Revenue function, R(p) = 9,900P - 50P²
Taking the derivative of R(p), we have:
R'(p) = 9,900 - 100P
100P = 9,900
Price, P = 9,900/100
Price, P = $99
For the the maximum revenue, we have:
Maximum revenue, R(p) = 9,900P - 50P²
Maximum revenue, R(p) = 9,900(99) - 50(99)²
Maximum revenue, R(p) = 980,100 - 490,050
Maximum revenue, R(p) = $490,050.

The population of a city can be modeled using the formula P=100,000e^(0.05t), where t is the number of years after 2012 and P is the city's population. Which of the following equations can be used to find the number of years after 2012 that the population will triple to 300,000?
Group of answer choices
t=3/(0.05e)
t=ln3/0.05
t=(ln200,000)/0.05
t=log3/0.05
The equation that can be used to find the number of years after 2012 that the population will triple to 300,000 is option B t = ln(3) / 0.05
Given,
The population of a city can be modeled using the formula P=100,000e^(0.05t)
t is the number of years after 2012
P is the population of the city
We have to find the equation that can be used to find the number of years after 2012 that the population will triple to 300,000.
Here,
Substitute 300000 in for P and solve for t
300000=100000e^0.05t
Divide both sides by 100000:
We get,
3 = e^0.05t
Multiply both sides by the natural log (ln)
Then,
ln(3) = 0.05t
Now, divide 0.05 on both sides to get t by its self
t = ln(3) / 0.05
Therefore,
The equation that can be used to find the number of years after 2012 that the population will triple to 300,000 is option B t = ln(3) / 0.05

Considering the following statements, what is X → Z? X → Y: If the sum of the interior angles of a shape is 180°, then it's a triangle. Y → Z: If a shape is a triangle, then it has three sides. Question 4 options: A) X → Z: If the sum of the interior angles of a shape is 180°, then it has three sides. B) X → Z: If a shape has three sides, then it's a triangle. C) X → Z: If a shape has three sides, then the sum of the interior angles of the shape is 180°. D) X → Z: If the sum of the interior angles of a shape isn't 180°, then it doesn't have three sides.
The correct statement that is a combination of both conditional statements is; X → Z: If the sum of the interior angles of a shape is 180°, then it has three sides.
How to interpret conditional statements?
A triangle is defined as a three-sided polygon that consists of three edges and three vertices. The most important property of a triangle is that the sum of the internal angles of a triangle is equal to 180 degrees.
We are given the conditional statements as;
X → Y: If the sum of the interior angles of a shape is 180°, then it's a triangle.
Y → Z: If a shape is a triangle, then it has three sides.
Now, transitive property states that “if two quantities are equal to a third quantity, then we can say that all the quantities are equal to each other”.
Thus, applying transitive property to our given statements we can say that; X → Z: If the sum of the interior angles of a shape is 180°, then it has three sides.

The angle measures are <1 = 86 degrees, <2 = 94 degrees and <3 = 86 degrees
How to determine the measure of each angle?The possible diagram that completes the question is added as an attachment
From the attached diagram, we have the following representation
<1 + <2 = 180 degrees --- by the theorem of supplementary angles
Also, we have the following angle measure
Given that
<1 = 86 degrees
Substitute the known values in the above equation
So, we have the following equation
86 + <2 = 180
Evaluate the like terms
<2 = 94
Also, we have
<3 = <1 --- by the theorem of vertical angles
Substitute the known values in the above equation
<3 = 86

The measure of ∠QTS = 58°
Given; A triangle QPR
PQ = PR
this means that ∠ Q = ∠ R
and QR = QT this means ∠ R = ∠ T
And ST ║ QR
and QT is the transversal
From the above mentioned information we can conclude that
∠QTS = ∠TQR -------------- 1
Thus since ∠ Q = ∠ R
by using angle sum property of triangle we can conclude that
∠ Q + ∠ R = 116 [ exterior angle sum property ]
2 ∠ Q = 116
∠ Q = 58°
this means ∠ TQR = 58°
And from 1 we know that this angle is equal to angle QTS
Thus ∠QTS = ∠TQR = 58°

A person must walk for at least

minutes in order to use at least 220 calories.
The person must walk 2.61 miles to use 220 calories with speed of 4mph.
What is speed?
The pace at which an object's position changes in any direction is known as its speed. The distance traveled relative to the time it took to travel that distance is how fast something is moving. Due to its lack of magnitude and only having a direction, speed is a scalar quantity.
Here, At 4 mph 5.6 calories are used in = 1 minute
So, at 4 mph, 220 calories are used in,
=> 220/5.6
=> 39.28 minutes
Hence, a person must walk for 39.28 minutes to burn 220 calories.
To find the distance a person should walk, when the speed is 4 miles per hour.
In 60 minutes a person is walking = 4 miles
So, in 39.28 minutes a person will walk = 4/60*39.28

What is the equation of the line that passes through the point (8, 2) and has a slope of -3/4
The equation of the line that passes through the point (8, 2) and has a slope of -3/4 is y = -3/4(x-8)+2.
In the given question we have to find the equation of line that passes through the point (8, 2) and has a slope of -3/4.
The given points are (8, 2).
The slope(m) = -3/4
The standard equation of slope intercept form is
y-y(1) = m(x-x(1))
From the question; x(1) = 8 and y(1) = 2.
Putting the value
y-2 = -3/4(x-8)
Add 2 on the both side, we get
y = -3/4(x-8)+2
Hence, the equation of the line that passes through the point (8, 2) and has a slope of -3/4 is y = -3/4(x-8)+2.

A company's contribution margin rate is the total revenue minus variable costs divided by the revenue.
First we need to determine the contribution margin in order to calculate the contribution margin rate. There are two approaches to determine the contribution margin.
Contribution Margin = Net Sales Revenue – Variable CostContribution Margin = Fixed Costs + Net IncomeContribution Margin = $15 - $9 = $6
