A small organization is responsible for distributing two craft products made in a small community, these products are jam and bread. The marginal utility function for the jam is f(x) = 55–4x, and the marginal utility for the package of bread is given by g(x) = 37–x.
Find:
a) The total utility function of the jam.
b) The total utility function of bread.
c) If the consumer wants to buy 2 jars of jam and 3 packages of bread, which of the items will produce more utility.
3 packages of bread would produce more utility than 2 jars of jam
The total utility function of the jamThe marginal utility function of jam is given as:
f(x) = 55 - 4x
Integrate the above function to determine the total utility function
f'(x) = 55x - 2x^2
Hence, the total utility function of the jam is f'(x) = 55x - 2x^2
The total utility function of breadThe marginal utility function of bread is given as:
g(x) = 37 - x
Integrate the above function to determine the total utility function
g'(x) = 37x - 0.5x^2
Hence, the total utility function of the bread is g'(x) = 37x - 0.5x^2
The items that produce more utilityWe have:
Jam = 2 jars
Bread = 3 packages
Substitute 2 for x in f'(x) = 55x - 2x^2
f'(2) = 55 * 2 - 2 * 2^2
f'(2) = 102
Substitute 3 for x in g'(x) = 37x - 0.5x^2
g'(3) = 37 * 3 - 0.5 * 3^2
g'(3) = 106.5
106.2 is greater than 102
Hence, 3 packages of bread would produce more utility

A circle is defined by the equation given below.
The centre of the circle is (1/2, 1) and the radius of the circle is 2 if the circle equation is x² + y² − x − 2y − 11/4 = 0
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)
The question is incomplete.
The complete question is:
A circle is defined by the equation given below.
x² + y² − x − 2y − 11/4 = 0
What are the coordinates for the centre of the circle and the length of the radius?
We know the standard form of a circle:
(x - h)² + (y - k)² = r²
Here (h, k) is the centre of the circle and r is the radius of the circle
[tex]\rm x^2 - x + \dfrac{1}{4} + y^2 - 2y + 1= \dfrac{11}{4} +\dfrac{1}{4} + 1\\\\[/tex]
[tex]\rm (x - \dfrac{1}{2})^2+(y-1)^2 = 2^2[/tex]

hi! The work I have is solving linear equations with fractions, i only have practice exercises so they should probably be a bit simple, shown work would be appreciated <3
Just 4 questions
1) y / 3 + 6 = -3 / 2
2) -2 / 3 r - 3 = 3
3) 2 / 3 - 2x = x
4) 7x / 2 + -5 / 2 = 9/2
I’ll add a photo of the problems in a simple format
The value of the variables are y = -45/2, r = -9, x = 2/9 and x = 2
How to solve the variables?(1) y/3 + 6 = -3/2
Multiply through by 3
y + 18 = -9/2
Subtract 18 from both sides
y = -18 - 9/2
Take LCM
y = (-18 * 2 - 9)/2
Evaluate
y = -45/2
(2) -2r/3 - 3 = 3
Multiply through by 3
-2r - 9 = 9
Add 9 to both sides
-2r = 18
Divide by 2
r = -9
(3) 2/3 - 2x = x
Multiply through by 3
2 - 6x = 3x
Add 6x to both sides
2 = 9x
Divide by 9
x = 2/9
(4) 7x/2 + -5/2 = 9/2
Multiply through by 2
7x - 5 = 9
Add 5 to both sides
7x = 14
Divide by 7
x = 2
Hence, the value of the variables are y = -45/2, r = -9, x = 2/9 and x = 2

A coordinate plane with 2 lines. The first line is labeled y equals f(x) and passes through (0, 4) and (1, 1) The second line is labeled y - g(x) and is horizontal passing through (negative 2, 2), (0, 2), and (2, 2). The lines intersect at a point that is slightly to the right of (0.5, 2).
If f(x) = −3x + 4 and g(x) = 2, solve for the value of x for which f(x) = g(x) is true.
The value of x if both lines intersect is 2/3
What is an equation?The equation in mathematics is the relationship between the variables and the number and establishes the relationship between the two or more variables.
Given the equation of a line that passed through the points (0, 4) and (1, 1) expressed as h(x) = -3x +4
The equation of the second line g(x) passing through the points (-2, 2) and (0, 2) is g(x) = 2
If the lines intersect, then h(x) = g(x)
Substituting the functions to get the value of "x"
-3x + 4 = 2
Subtract 4 from both sides
-3x + 4 - 4 = 2 - 4
-3x = - 2
Divide both sides by - 3
x = 2 / 3
Hence the value of x if both lines intersect is 2/3

Standard deviation; σ = 3.3
Thus;
z-score for a mean score of 75.8 is;
z = (75.8 - 82.4)/3.3
z = -2
z-score for a mean score of 89 is;
z = (89 - 82.4)/3.3
z = 2

a cylinder tin,7cm high,is closed at one end.if its total surface area is 462cmsquare,calculate its radius
A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The radius of the cylindrical tin is 7 cm.
What is a cylinder?A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The circular bases' centers overlap each other to form a right cylinder.
The height of the cylindrical tin can is 7 cm, while the total surface area is 462 cm². Therefore, the total surface area of the tin will be,
The total surface area = area of base + Lateral surface area
462 cm² = πR² + 2πRH
462 = π(R² + 2R7)
147 = R² + 14R
R² + 14R - 147 = 0
R = 7, -21
Since the radius can not be negative.
Hence, the radius of the cylindrical tin is 7 cm.

Construct OD and BD. Then, in quadrilateral ABOD, angles ODA and OBA are right angles and thus angle DOB is 130 degrees (since angles in a quadrilateral add to 360 degrees).
So, this means arc DB also measures 130 degrees. Hence, by the inscribed angle theorem, angle BCD is 65 degrees.

If you receive a 25% DISCOUNT off an item costing $22.00, how much money do you save?
Answer:
The amount of money you saved by receiving a discount of 25% is $5.5
Step-by-step explanation:
Discount is the reduction in the price of goods or services offered by shopkeepers at the marked price. Selling price is the actual price at which an article is sold after any reduction or discounts in the cost price.
discount is always calculated on the cost price of the article
formula to calculate the discount and discount %
Discount = List Price - Selling Price
Discount (%) = (Discount/cost price) × 100
here, in the question discount % is given = 25%
cost price of the item = $22
therefore using the above mentioned discount percentage formula:
25 = (Discount/22)×100
25/100 = Discount/ 22
0.25 × 22 = Discount
$5.5 = Discount
