a. $722,500
c. $180,625
b. $1,445,000
d. $361,250
The maximum revenue, to the nearest whole dollar, is $180,625 (option c).
To find the maximum revenue, we need to determine the vertex of the quadratic function represented by the revenue equation.
The revenue equation is given as:
R(p) = -4p² + 1700p
The vertex of a quadratic function in the form of f(x) = ax² + bx + c can be found using the formula:
x = -b / (2a)
For the given revenue equation, a = -4 and b = 1700. Plugging these values into the formula, we have:
p = -1700 / (2 × -4)
p = -1700 / -8
p = 212.5
The maximum revenue occurs at p = 212.5.
To find the maximum revenue, we substitute this value back into the revenue equation:
R(p) = -4(212.5)² + 1700(212.5)
R(p) = -4(45256.25) + 361250
R(p) = -181025 + 361250
R(p) = 180625

Name two other positive angles of rotation that take A to B. Explain your reasoning
The two other positive angles of rotation that take A to B are 19π/6 and 31π/6.
How to explain the anglesThe unit circle is rotationally symmetric, meaning that any angle of rotation on the unit circle will take a point to another point on the unit circle with the same distance from the origin. This means that if we rotate point A by 7π/6 radians, we can also rotate it by 19π/6 or 31π/6 radians and end up at the same point B.
The point A has polar coordinates (1, 0). This means that it is located at a distance of 1 unit from the origin and has an angle of 0 radians with the positive x-axis.
The point B has polar coordinates (√3/2, 1/2). This means that it is located at a distance of √3/2 units from the origin and has an angle of 7π/6 radians with the positive x-axis.
If we rotate point A by 19π/6 radians, we get a point with polar coordinates (√3/2, -1/2). This point is located at the same distance from the origin as point B and has the same angle with the positive x-axis.
Therefore, the two other positive angles of rotation that take A to B are 19π/6 and 31π/6.

The value of an automobile company's stock fell 5 points over the last month.
What integer represents the change in the stock's value?
The value of an automobile company's stock fell 5 points over the last month. The integer that represents the change in the stock's value is -5.
In the context of stock market performance, positive values typically indicate an increase in the stock's value, while negative values indicate a decrease. In this case, since the stock's value fell by 5 points, we assign a negative sign to represent the change.
By convention, negative numbers are used to represent decreases or losses, while positive numbers represent increases or gains. When the stock's value decreases, it is common to use negative integers to signify the change.
In this scenario, a decrease of 5 points is denoted by the negative sign (-) followed by the numerical value 5. Therefore, the integer -5 represents the change in the stock's value.
Using this notation helps provide clarity and consistency in understanding the direction and magnitude of changes in stock prices. It allows investors, analysts, and market participants to communicate and interpret market movements accurately and effectively.

b. 3x⁷y - 2x²y³
c. 3x⁹y³ - 2x⁴y⁵
d. None of these choices are correct.
Answer: B
Step-by-step explanation:
The coefficients 9 & 6, divided by 3, equal 3 & 2.
For the exponents, if you divide the entire equation by xy, you need to subtract the corresponding exponents of x and y. Subtract the denominator's exponent from the numerator's exponent.
So, for the first part x^8/x^1=x^7
y^2/y^1=y
For the second part: x^3/x=x^2
y^4/y=y^3
So, if you put the coefficients and both parts of the equation together, you get 3x^7y - 2x^2y^3 (answer letter B).

Determine the amplitude of function
The amplitudes of functions are a) 8 and b) 6.
Given are the functions we need to determine the amplitude of function,
a) y = 8 Sin (x/2) + 3
b) y = 6 Cos x + 2
So,
To determine the amplitude of a trigonometric function, you can follow these steps:
For a sine function of the form y = A×sin(Bx + C) + D:
The amplitude is equal to the absolute value of the coefficient A.
For a cosine function of the form y = A×cos(Bx + C) + D:
The amplitude is equal to the absolute value of the coefficient A.
Let's apply these steps to the given functions:
a) y = 8×sin(x/2) + 3
The coefficient of sin in this function is 8, so the amplitude is |8| = 8.
Therefore, the amplitude of function a) is 8.
b) y = 6×cos(x) + 2
The coefficient of cos in this function is 6, so the amplitude is |6| = 6.
Therefore, the amplitude of function b) is 6.
Hence the amplitudes of functions are a) 8 and b) 6.

Step-by-step explanation:
if the values of SN and SP are the same, so are the corresponding sides next to the right angles.
which means:
if SP = SN, then JK = LM.
Use the reverse version of the function for calculating LM (3x + 2).
-2 * 1/3
Now apply that function to 20.

B). No two lines are parallel
Step-by-step explanation:
In spherical geometry, there are no parallel lines. This is because any two lines on a sphere will eventually intersect.
The sum of two numbers is 28. The first number is 7 more than twice the second number. Let a represent the first number. Let b represent the second number. What is the second number? Use the table to guess and check. Two Numbers a b a + b = 28 Check a = 2 b + 7
Answer:
Let’s solve this problem step by step. Since a + b = 28 and a = 2b + 7, we can substitute the value of a in the first equation to get 2b + 7 + b = 28. Solving for b, we get 3b + 7 = 28, which means 3b = 21 and b = 7. So, the second number is 7.

C'(x) = 0.046875x² − x + 100
₂∫¹⁰C'(x)dx = ₂∫¹⁰(0.046875x² − x + 100)dx
₂∫¹⁰C'(x)dx = ₂∫¹⁰(0.046875x²)dx − ₂∫¹⁰(x)dx + ₂∫¹⁰(100)dx
₂∫¹⁰C'(x)dx = 0.046875x³/3|¹⁰₂ - x²/2|¹⁰₂ + 100x|¹⁰₂
₂∫¹⁰C'(x)dx = 0.015625(10³ - 2³) - 1/2(10² - 2²) + 100(10 - 2)
₂∫¹⁰C'(x)dx = 0.015625(1000 - 8) - 0.5(100 - 4) + 100(8)
₂∫¹⁰C'(x)dx = 0.015625(992) - 0.5(96) + 800
₂∫¹⁰C'(x)dx = 15.5 - 48 + 800
₂∫¹⁰C'(x)dx = $767.50

Using the trigonometric ratios:
(1). sinA = 5/13, cosA = 12/13 and tanA = 5/13. And by Pythagoras rule:
(2). x = √116
(3). x = 90
What is trigonometric ratios?The trigonometric ratios is concerned with the relationship of an angle of a right-angled triangle to ratios of two side lengths.
The basic trigonometric ratios includes;
sine, cosine and tangent.
(1). sinA = 5/13 {opposite/hypotenuse}
cosA = 12/13 {adjacent/hypotenuse}
tanA = 5/13 {opposite/adjacent}
By Pythagoras rule
(2). x = √(4² + 10²)
x = √(16 + 100)
x = √116
(3). 106² = x² + 56²
x² = 106² - 56²
x = √(11236 - 3136)
x = √8100
x = 90
Therefore, using trigonometric ratios:
(1). sinA = 5/13, cosA = 12/13 and tanA = 5/13. And by Pythagoras rule;
(2). x = √116
(3). x = 90

Answer:
Step-by-step explanation:
ll hypothesis The critical value for this test is 9.488. Based on the test statistic of 1.358, we fail to reject the null hypothesis that the amount of smoking is independent of seat belt use. In other words, there is not enough evidence to support the claim that seat belt use and smoking habits are related.

An artist made a cone of stainless steel, then sliced it into three pieces. what is the volume of the largest piece? PLEASE SHOW WORK AND EXPLAIN HOW YOU GOT YOUR ANSWER I WILL MARK YOU BRAINLIEST!!!
The volume of the largest piece is 10, 597. 5 cm³
How to determine the volumeThe largest part of the cone takes the shape of a cylinder.
Now, the formula for calculating the volume of a cylinder is expressed as;
V = πr²h
The parameters of the formula are enumerated as;
V is the volume of the cylinder.r is the radius of the cylinder.h is the height of the cylinder.Now, substitute the values, we get;
Diameter = 2 radius
Radius = 30/2
Radius = 15cm
Height = 15cm
Now, substitute the values, we get;
Volume = 3.14 × 15² ×15
Find the square value and substitute, we have;
Volume = 10, 597. 5 cm³
