1. The price-demand equation for the trumpets is:
x = 238.18 - 1.09p
2. The manufacturer should set the price of each trumpet at $296.50 to break even
3. The manufacturer should set the price of each trumpet at $138.63 to maximize profit.
In this problem, the manufacturer has conducted a customer survey and found out that the price of each trumpet affects the demand for it. We need to analyze this data and come up with a price-demand equation that helps the manufacturer set the price of each trumpet to maximize profit.
To start with, we need to assume a linear model, where the demand for the trumpets is directly proportional to the price. We can represent the demand as "x" and the price as "p". Using the data from the survey, we can form two linear equations:
110 = ap + b (1)
128 = cp + d (2)
Here, a, b, c, and d are constants that we need to find. We can solve these equations simultaneously to get the values of a, b, c, and d.
Subtracting equation (2) from equation (1), we get:
-18 = (a-c)p + (b-d) (3)
Dividing both sides of equation (3) by -18, we get:
p = (d-b)/(c-a) (4)
Using equation (4), we can find the value of p, which is the price at which the demand for trumpets is equal to the values obtained from the survey. Substituting the values from either equation (1) or (2) into equation (4), we get:
p = ($160.74 x 110 - $220.18 x 128)/(-18 x 110 + 18 x 128)
= $186.46
Therefore, the price-demand equation for the trumpets is:
x = 238.18 - 1.09p
To answer the second question, we need to find the price of each trumpet at which the manufacturer will break even. In other words, the revenue earned from selling the trumpets should be equal to the total cost incurred in making and selling them.
We know that the one-time cost of buying equipment is $3274.78, and each trumpet costs $90.05 to make. Let's represent the break-even price as "\(P_{be}\)". Then we can form the following equation:
110\(P_{be}\) = 3274.78 + 110 x 90.05
Solving for \(P_{be}\), we get:
\(P_{be}\)= $296.50
Therefore, the manufacturer should set the price of each trumpet at $296.50 to break even.
To answer the third question, we need to find the price of each trumpet that maximizes the profit for the manufacturer.
The profit is given by the revenue earned minus the total cost incurred. Let's represent the profit as "P" and the price as "p". Then the profit equation becomes:
P = xp - (3274.78 + 90.05x)
To find the price that maximizes profit, we need to take the derivative of the profit equation with respect to p and equate it to zero.
dP/dp = x - 90.05 = 0
Solving for x, we get:
x = 90.05
Substituting this value of x into the price-demand equation, we get:
p = $138.63
Therefore, the manufacturer should set the price of each trumpet at $138.63 to maximize profit.

Answer:
y is greater than or equal to 1
Step-by-step explanation:
The function opens upward and the lowest point is (2,1). The y-values are infinite as long as it is greater than 1.
Step-by-step explanation:
I guess D means domain, R means range.
and what is the question about Function ? if it is a function ? I assume that.
4)
the domain is the interval or set of all valid x (input) values.
there is nothing "forbidden" or strange in the expression, so, x can have any value from -infinity to +infinity.
-infinity < x < +infinity
5)
the range is the interval or set of all valid y (result) values.
if x = 0, y = -5
if x = 1, y = -8
if x = 2, y = -9
if x = 3, y = -8
if x = 4, y = -5
since such a parabola is a symmetric function, we see the vertex, the extreme point and point of symmetry to be x = 2.
and that is the minimum of the parabola (x = 2, y = -9), which is clearly opening up.
the range (of y) is therefore
-9 <= y < +infinity
or simply
y >= -9
6)
yes, it is a function, as every x has exactly one possible result value.
as we can see, multiple x values can have the same y value, but that is not a problem for a function. but one x value cannot have multiple y values (and that is clearly not violated here : every x has one y value).
Two pulleys, one with radius r 1r1 and the other with radius r 2r2, are connected by a belt. The pulley with radius r 1r1 rotates at omega 1ω1 revolutions per minute, whereas the pulley with radius r 2r2 rotates at omega 2ω2 revolutions per minute. Show that StartFraction r 1 Over r 2 EndFraction equals StartFraction omega 2 Over omega 1 EndFraction r1 r2
Answer:
r1/r2 = 2ω2/ω1
Step-by-step explanation:
The velocity of each pulley is expressed as v = ωr where;
v is the linear velocity of the pulley
ω is the angular velocity of the pulley
r is the radius of the pulley.
For the two pulleys, the velocity I'd both pulleys are the same.
v1 = v2
v1 is the linear velocity of first pulley
v2 is the linear velocity of the second pulley.
v1 = ω1r1
v2 = 2ω2(r2)
r1 and r2 is the radius of pulley 1 and pulley 2 respectively.
Since v1 = v2
ω1r1 = 2ω2(r2)
Divide both sides by r2
ω1r1/r2 = 2ω2(r2)/r2
ω1r1/r2 = 2ω2
Divide both sides by ω1
ω1r1/r2/ω1= 2ω2/ω1
r1/r2 = 2ω2/ω1
The function f(x) = 2x^3 – 36x^2 + 192x + 5 has one local minimum and one local maximum. This function has a local minimum at x equals with value and a local maximum at requals with value
The function has a local minimum at x = 8 with a value of 69, and a local maximum at x = 4 with a value of -267.
To find the local minimum and local maximum of the function f(x) = 2x^3 - 36x^2 + 192x + 5, we first need to find the critical points. We do this by finding the first derivative of the function and setting it equal to zero.
f'(x) = 6x^2 - 72x + 192
Now, set f'(x) = 0 and solve for x:
6x^2 - 72x + 192 = 0
Divide by 6:
x^2 - 12x + 32 = 0
Factor:
(x - 4)(x - 8) = 0
So, the critical points are x = 4 and x = 8. To determine whether these points are local minima or maxima, we can use the second derivative test.
Find the second derivative:
f''(x) = 12x - 72
Now, evaluate the second derivative at x = 4 and x = 8:
f''(4) = 12(4) - 72 = -24 (negative, so it's a local maximum)
f''(8) = 12(8) - 72 = 48 (positive, so it's a local minimum)
Finally, find the values of the function at these points:
f(4) = 2(4)^3 - 36(4)^2 + 192(4) + 5 = -267
f(8) = 2(8)^3 - 36(8)^2 + 192(8) + 5 = 69
So, the function has a local minimum at x = 8 with a value of 69, and a local maximum at x = 4 with a value of -267.

How do you score 102 students play at least once by there is 40% of the students at the school how many students are at the school
If 102 students at least plays one sport and this is 40% of the students at the school, then there 255 students at the school
Let's assume that the total number of students in the school is "x".
40 percentage of the students at the school play at least one sport. So, the number of students who play at least one sport is 0.4x.
We also know that the number of students who play at least one sport is 102. Therefore, we can write:
0.4x = 102
Move 0.4 to the right hand side of the equation
x = 102 / 0.4
Divide the numbers
x = 255

The length of the highway is 600 miles. If 2 inches represent 75 miles, what is the length of the highway on the map?
Answer:
16 inches
Step-by-step explanation:
The variables in this equation are miles and inches. You're given the ration 2 inches: 75 miles. Take the other factor that you are given, which for this problem would be 600 miles, and divide it by the number with the same variable, which would be 75 miles. This comes out to be 8, to which you then multiply that by the number with the variable that you are trying to find, which is two. Therefore, the length of the highway on the map would be 16 inches.

2x = 57- 1
2x = 56
Divide both sides by 2
x = 56/2

The length of a rectangle is 3 inches longer than it is wide. If the area is 108 square inches, what are the dimensions of the rectangle
Answer:
width = 9 inches , length = 12 inches
Step-by-step explanation:
let width be w then length = w + 3
area (A) of a rectangle is calculated as
A = length × width
= (w + 3) × w = w(w + 3) = w² + 3w
given A = 108 , then
w² + 3w = 108 ( subtract 108 from both sides )
w² + 3w - 108 = 0 ← in standard form
(w + 12)(w - 9) = 0 ← in factored form
equate each factor to zero and solve for w
w + 12 = 0 ⇒ w = - 12
w - 9 = 0 ⇒ w = 9
however, w > 0 , so w = 9 and w + 3 = 9 + 3 = 12
then width = 9 inches and length = 12 inches
9-7w=8w+8
what is w??
Answer:

Step-by-step explanation:
Step 1: Simplify both sides of the equation.

9+−7w=8w+8
−7w+9=8w+8
Step 2: Subtract 8w from both sides.
−7w+9−8w=8w+8−8w
−15w+9=8
Step 3: Subtract 9 from both sides.
−15w+9−9=8−9
−15w=−1
Step 4: Divide both sides by -15.
−15w/−15 = −1/−15
w = 1/15
