To maximize revenue for John Deere's heavy-duty tractors, the optimal unit price is found by determining the vertex of the provided quadratic revenue function R(p). Using the vertex formula, the unit price p that maximizes revenue is $1520.
Maximizing Revenue for John Deere Heavy-Duty Tractors
To find the unit price that maximizes revenue for John Deere heavy-duty tractors, we need to analyze the revenue function R(p) provided, which follows a quadratic format:
R(p) = [tex](-1/2)p^2[/tex] + 1520p
To find the maximum revenue, we can use the fact that the vertex of a parabola described by a quadratic equation y = ax^2 + bx + c provides the maximum or minimum value of the function. Since our equation is in the form of a parabola opening downwards (because the coefficient of p^2 is negative), the vertex will give us the maximum revenue point.
The formula for the p-coordinate (horizontal axis) of the vertex of a parabola is given by -b/(2a). In this case, a = -1/2 and b = 1520, therefore:
p = -b/(2a) = -1520/(2 * (-1/2)) = -1520/(-1) = 1520
Hence, the unit price p should be set at $1520 to maximize revenue for the sale of heavy-duty tractors. This value is already an integer, so rounding to the nearest dollar is not necessary.
The base angle of an isosceles triangle measures 54°. What is the measure of its vertex angle?
Answer:
72[tex]\degree[/tex]
Step-by-step explanation:
We know that the sum of all the angles of any triangle is 180[tex]\degree[/tex]
We have to use the above property in order to find the measurement of the vertex angle.
Now our triangle is isosceles , that is the two equal sides will be containing equal angle. One of them is given as 54[tex]\degree[/tex]
And hence the other will also be 54[tex]\degree[/tex].
Let the vertex angle be x
180=54+54+×
180=108+×
x=180-108
x=72
Hence the vertex angle is 72[tex]\degree[/tex]

Solve the system of equations using the elimination method.
8x + 7y = 89
2x + 5y = 45
Explain each step and show how to verify your results.
PLEASE HURRY!!! i promise brainliest answer to the first CORRECT answer
8x + 7y =89
2x + 5y=45
You want to be able to subtract one away from the other one so you are just left with either x or y. to do this we could multiply the bottom equation by 4
so you would get
8x+7y=89
8x + 20y= 180
Now we can subtract equation 1 from equation 2 so you get
13y=91
this gives you y=7 so to find x we can simply substitute y into an equation;
2x + 5x7=45
2x + 35= 45
2x = 10
x =5
so the final answer is y = 7/ x = 5

Justify each step of the solution by stating the property that was used to get to each step.
Given:
Step 1:
Step 2:
Step 3: 17x = 40
Step 4:
Step 1: Distributive Property. Step 2: Combine like terms. Step 3: Add 34x to both sides. Step 4: Divide by 17. x = 60/17.
Here's a step-by-step solution to the equation 2(10 - 13x) + 9x = -34x + 60, along with the properties used at each step:
Given equation: 2(10 - 13x) + 9x = -34x + 60
Step 1: Distribute the 2 on the left side of the equation.
Property used: Distributive Property
2 * 10 - 2 * 13x + 9x = -34x + 60
20 - 26x + 9x = -34x + 60
Step 2: Combine like terms on both sides of the equation.
Property used: Combining like terms
-26x + 9x = -34x + 60
(-26x + 9x) = (-34x + 60)
-17x = -34x + 60
Step 3: Add 34x to both sides of the equation to isolate the variable x on the right side.
Property used: Adding the same value to both sides of an equation to maintain equality.
-17x + 34x = -34x + 60 + 34x
17x = 60
Step 4: Finally, divide both sides by 17 to solve for x.
Property used: Dividing both sides of the equation by the same nonzero value to maintain equality.
(17x) / 17 = 60 / 17
x = 60 / 17
So, the solution to the equation is:
x = 60 / 17
Each step in this solution is justified by the properties of equality and arithmetic operations.
The complete question is here:
Justify each step of the solution by stating the property that was used to get to each step. Given: 2 (10-13x) + 9x = -34x + 60 Step 1: 20 - 26x + 9x = -34x + 60 Step 2: -17x = -34x + 10 Step 3: 17x = 40 Step 4: x =( 40)/(17) 40 on top of 17 as a fraction.
For several years, the state of New Hampshire Fish and Game Department earned several thousand dollars each year by auctioning wildlife killed along the Granite State’s roadways. The “road kill,” required to be in relatively good shape, was stored in a large freezer until the annual December auction. During the most recent auction three different collections of species made up the vast majority of frozen wildlife up for bid. Each of those collections made up one- third of the combined total. There was a set of bobcats, foxes and otters. There was a group of beavers and fishers (a weasel like animal). The final third was a large collection of black bears. Beavers made up 16.1% of the overall total. There were as many bobcats as beavers. There were four more foxes than otters. There were 16 fishers. What was the total number of road kill in these three collections, and how many were there of each species? (Hint: one-third equals 33.3%)
Final answer:
To find the total number of road kill in the three collections, we set up and solve an equation. Each species is assigned a variable, and using the information given, we can find the number of animals in each collection.
Explanation:
To find the total number of road kill in the three collections, we need to determine how many animals are in each collection. Let's assign variables to each species: bobcats = x, beavers = 16.1%x, foxes = x + 4, otters = x - 4, fishers = 16.1%. Given that each collection makes up one-third of the total, we can set up the equation: x + 16.1%x + x + x - 4 + 16.1%x = (1/3) * total. Simplifying the equation, we get 3.3x - 4 = (1/3) * total. Since beavers make up 16.1% of the total, we can substitute 16.1%x for beavers in the equation: 3.3x - 4 = (1/3) * total. Solving for x, we get x = (4 + (1/3) * total) / 3.3. Since bobcats and beavers have the same number, x = 16.1%x, which can be written as x = 0.161x. Equating the two, we get x = 0.161x. Finally, solving for x, we find that x = 0.161x, which simplifies to x = 0.161x. Therefore, each collection has the following numbers of animals: bobcats = 0.161x, beavers = 16.1%x, foxes = x + 4, otters = x - 4, and fishers = 16.1% total.
Find parametric equations for the sphere centered at the origin and with radius 3. Use the parameters s and t in your answer.
Final answer:
Parametric equations for a sphere centered at the origin with radius 3 are x = 3 sin(t) cos(s), y = 3 sin(t) sin(s), and z = 3 cos(t), where t is the angle from the vertical and s is the angle from the x-axis on the xy-plane.
Explanation:
To find parametric equations for a sphere centered at the origin with radius 3 using parameters s and t, we make use of spherical coordinates. In spherical coordinates, a point on the sphere can be expressed as:
x = r sin(t) cos(s)
y = r sin(t) sin(s)
z = r cos(t)
Where r is the radius of the sphere, t is the angle with the vertical (ranging from 0 to π), and s is the angle on the xy-plane from the x-axis (ranging from 0 to 2π). Given that the radius r is 3, the parametric equations become:
x( s, t) = 3 sin(t) cos(s)
y( s, t) = 3 sin(t) sin(s)
z( s, t) = 3 cos(t)
Final answer:
To find the parametric equations for a sphere with radius 3 centered at the origin, we use spherical coordinates with parameters s and t to define the x, y, and z components in terms of trigonometric functions. The resulting parametric equations are x(s, t) = 3sin(t)cos(s), y(s, t) = 3sin(t)sin(s), and z(s, t) = 3cos(t).
Explanation:
Finding Parametric Equations for a Sphere
To find the parametric equations for a sphere centered at the origin with radius 3 using the parameters s and t, we use spherical coordinates. In spherical coordinates, you can represent any point on the surface of a sphere using two angles, commonly named θ (theta) and φ (phi), and the radius r. Since we're given a radius of 3, we can set r to be 3.
The standard spherical coordinates in terms of s and t can be expressed as:
x(s, t) = 3sin(t)cos(s)y(s, t) = 3sin(t)sin(s)z(s, t) = 3cos(t)Here, t represents the polar angle, measured from the positive z-axis, and s is the azimuthal angle in the xy-plane from the positive x-axis. The range of these parameters is usually 0 ≤ t ≤ π and 0 ≤ s < 2π to cover the entire surface of the sphere.
In our scenario, t and s would correspond to the angles θ and φ in spherical coordinates, respectively. However, we should specify the domain of the parameters to avoid ambiguity. This solution shows how to set up parametric equations for a sphere by using trigonometric functions to relate the spherical coordinates to Cartesian coordinates.

How are the two functions f(x) = 0.7(6)x and g(x) = 0.7(6)–x related to each other?
The functions f(x) = 0.7(6)x and g(x) = 0.7(6)–x are related to each other. f(x) represents exponential growth, while g(x) represents exponential decay. As f(x) increases, g(x) decreases, and vice versa.
Explanation:These two functions, f(x) = 0.7(6)x and g(x) = 0.7(6)–x, are related to each other in the following ways:
The function f(x) represents exponential growth, where the base is 0.7(6) and the exponent is x. As the value of x increases, f(x) will increase exponentially.The function g(x) represents exponential decay, where the base is 0.7(6) and the exponent is -x. As the value of x increases, g(x) will decrease exponentially.Therefore, f(x) and g(x) are related inversely to each other. As f(x) increases, g(x) decreases, and vice versa.

A tangent-tangent angle intercepts two arcs that measure 135 degrees and 225 degrees. What is the measure of the tangent tangent angle?
Answer:
[tex]M=45 degrees[/tex]
Step-by-step explanation:
It is given that A tangent-tangent angle intercepts two arcs that measure 135 degrees and 225 degrees, thus in this the vertex lies outside, therefore

Evaluate the definite integral from x=0 to x=1
the cubed root of (1 + 7x) dx
To evaluate the definite integral from x=0 to x=1 of the cubed root of (1 + 7x), we need to find the antiderivative, then calculate the difference in its values at x=1 and x=0 according to the fundamental theorem of calculus.
Explanation:The task is to evaluate the definite integral from x=0 to x=1 of the cubed root of (1 + 7x). To find the integral of this function, we need to apply the fundamental theorem of calculus. This theorem allows us to evaluate definite integrals as the net or accumulated area under the curve from one point to another.
Let's denote the function to integrate as f(x) = (1 + 7x)^(1/3). Our goal is to find the integral of f(x) with respect to x, within the bounds of 0 to 1.
To solve this integral, we would typically look for a suitable antiderivative of f(x), which, when evaluated at the upper and lower limits of integration, would provide us with the definite integral value.
