why do some numerical expressions contain parentheses
The most basic and common reason to use parentheses, brackets, and braces is to control the order of operations.
What are parentheses?In mathematics, parenthesis is used to arrange numbers in the sequence of operations, clarify numbers, and denote multiplication.
Suppose you have an expression as:-
E = { ( 5-2 )8} 6
In this case, you would calculate 5 minus 2 first (parentheses), then multiply by 8 (brackets), then complete the part inside the curly braces, and finally multiply by 6.
Therefore the most basic and common reason to use parentheses, brackets, and braces is to control the order of operations.

If trapezoid JKLM is translated using the rule (x, y) → (x + 3, y − 3) and then translated using the rule (x, y) → (x − 1, y + 1) to create trapezoid J″K″L″M″, what is the location of L″?
The location of L″ is (-5, 0).
To find the location of L″, we first need to apply the first translation rule to the coordinates of trapezoid JKLM:
J': (x, y) → (x + 3, y - 3) => J'(-2+3, 1-3) = J(1, -2)
K': (x, y) → (x + 3, y - 3) => K'(1+3, 1-3) = K(4, -2)
L': (x, y) → (x + 3, y - 3) => L'(3+3, -2-3) = L(6, -5)
M': (x, y) → (x + 3, y - 3) => M'(-4+3, 2-3) = M(-1, -1)
Now, we need to apply the second translation rule to the coordinates of J', K', L', and M':
J'': (x, y) → (x - 1, y + 1) => J''(1-1, -2+1) = J''(0, -1)
K'': (x, y) → (x - 1, y + 1) => K''(4-1, -2+1) = K''(3, -1)
L'': (x, y) → (x - 1, y + 1) => L''(6-1, -5+1) = L''(5, -4)
M'': (x, y) → (x - 1, y + 1) => M''(-1-1, -1+1) = M''(-2, 0)
Therefore, the location of L″ is (-5, 0).

Step-by-step explanation:
Parametric point from A (2,1,0) to B(-2,0,1)
The parametric equations are mathematically given as
(x(t), y(t), z(t))= (2-4t, 1-t, t)
What is a Parametric point?Generally, To express the parametric point from A (2,1,0) to B(-2,0,1) in parametric form, we can use the following equation:
P(t) = (2-4t, 1-t, t)
To find the parametric equations for a point moving from A to B, we can use the following formula:
x = x₁ + t(x₂ - x1)
y = y₁ + t(y₂ - y₁)
z = z₁ + t(z₂ - z₁)
Where (x₁, y₁, z₁) is the starting point (A), (x₂, y₂, z₂) is the ending point (B), and t is a parameter that varies from 0 to 1.
Using this formula, the parametric equations for a point moving from A (2,1,0) to B(-2,0,1) are:
x = 2 + t(-2 - 2)
= 2 - 4t
y = 1 + t(0 - 1)
= 1 - t
z = 0 + t(1 - 0)
= t
These equations describe the motion of a point that starts at A, moves along the line segment from A to B, and arrives at B when t = 1.

-1/4 plus 3/5
Answer or else
The algebric expression -1/4 + 3/5 is equal to 7/20 when simplified.
To solve the expression -1/4 + 3/5, we need to find a common denominator for the fractions and then perform the addition.
The common denominator for 4 and 5 is 20. We can rewrite the fractions with this denominator:
-1/4 = -5/20
3/5 = 12/20
Now that the fractions have the same denominator, we can add them:
-5/20 + 12/20 = (-5 + 12)/20 = 7/20
Therefore, -1/4 + 3/5 is equal to 7/20.
To further simplify the fraction, we can check if there is a common factor between the numerator and denominator. In this case, 7 and 20 have no common factors other than 1, so the fraction is already in its simplest form.
Thus, the final answer is 7/20.

A Kenkey seller operates in two markets. In market 1, research indicates that the price elasticity of demand is (-) 0.25 while that for market 2 is (-) 2.5. The seller has decided to reduce the price of Kenkey by 10% this month in both markets.
i. Calculate the percentage change in quantity demand for Kenkey in both markets. Explain the result of the Kenkey seller’s action on the total revenue for both markets.
ii. Compute the marginal revenue for both markets if the price charged in market 1 and 2 are GH¢ 2 and GH¢ 1.50 respectively.
iii. As the firm’s adviser, suggest an alternative pricing strategy to the Kenkey seller.
In market 1, the quantity demanded will increase by 2.5% while in market 2, the quantity demanded will increase by 25%.
How to calculate the value% Change in Quantity Demanded (Market 1) = (-) 0.25 * (-10%) = 2.5%
% Change in Quantity Demanded (Market 2) = (-) 2.5 * (-10%) = 25%
The negative sign for price elasticity of demand means that demand is inversely related to price.
For market 1:
Price = GH¢ 2
Quantity demanded = Q1
Change in price = -10% x GH¢ 2 = -GH¢ 0.20
Change in quantity demanded = 2.5% x Q1
Change in revenue = GH¢ 2.00 x 2.5% x Q1 = GH¢ 0.05 Q1
Marginal revenue = Change in revenue / Change in quantity demanded
Marginal revenue = (GH¢ 0.05 Q1) / (2.5% x Q1)
Marginal revenue = GH¢ 2.00
For market 2:
Price = GH¢ 1.50
Quantity demanded = Q2
Change in price = -10% x GH¢ 1.50 = -GH¢ 0.15
Change in quantity demanded = 25% x Q2
Change in revenue = GH¢ 1.50 x 25% x Q2 = GH¢ 0.375 Q2
Marginal revenue = Change in revenue / Change in quantity demanded
Marginal revenue = (GH¢ 0.375 Q2) / (25% x Q2)
Marginal revenue = GH¢ 1.50
iii. An alternative pricing strategy for the Kenkey seller could be to implement a tiered pricing system based on the price elasticity of demand in each market.

The image of (-9,12) after a dilation by a scale factor of 1/3 centered at the origin is (-3,4).
In the given question,
We have to find the image of (-9,12) after a dilation by a scale factor of 1/3 centered at the origin.
Since we have to find the image after a dilation.
So we learn about it now,
Any scale factor will dilate the image of any coordinate. A specific scale factor can be used to scale the coordinate up or down. To determine the answer, consider the scale factor in the equation and multiply or divide the coordinates of dilation by the appropriate scale factor.
So the given point is (-9,12).
Scale factor is 1/3.
So the image of (-9,12) after a dilation by a scale factor of 1/3 centered at the origin is define as
=(-9×1/3,12×1/3)
Simplifying
=(-3,4)
Hence, the image of (-9,12) after a dilation by a scale factor of 1/3 centered at the origin is (-3,4).

In the diagram below, m is the perpendicular bisector of BC.
If BK = 5x, AC = 6x + 7, CP = 4x, AB = 9x – 14. Find BC
Answer:
BC = 56 units
Step-by-step explanation:
since the main diagonal AK bisects the diagonal BC , then the figure is a kite.
• the disjoint pairs of consecutive sides are congruent in a kite, that is
AB = AC and BK = CK
using the pair AB = AC to solve for x
9x - 14 = 6x + 7 ( subtract 6x from both sides )
3x - 14 = 7 ( add 14 to both sides )
3x = 21 ( divide both sides by 3 )
x = 7
Since m bisects BC , then
CP = PB and
BC = CP + PB = 4x + 4x = 8x
then
BC = 8x = 8 × 7 = 56

slide and its ladder form a right triangle with the ground, with the
slide representing the hypotenuse. The top of the ladder is 10 feet above
the ground, and the bottom of the ladder is 12 feet from the bottom of
the slide. What is the length of the slide to the nearest tenth of a foot?
1. Use the information in the problem to label the diagram.
Answer:
1. The problem involves finding the length of a slide about a ladder. The slide and the ladder form a right triangle, with the ground and the slide as the hypotenuse.
2. The top of the ladder is 10 feet above the ground, and the bottom of the ladder is 12 feet from the bottom of the slide.
3. In order to solve this problem, a diagram can be used to represent the scenario.
4. Label the bottom of the slide as point A, the bottom of the ladder as point B, and the top of the ladder as point C.
5. Draw a straight line from point A to point B and label it 12 feet.
6. Draw a straight line from point B to point C and label it 10 feet.
7. Draw a straight line from point A to point C, which is the hypotenuse of the triangle.
8. Use the Pythagorean Theorem to find the length of the hypotenuse.
9. The Pythagorean Theorem states that a2 + b2 = c2, where a and b are the sides of the triangle and c is the hypotenuse.
10. In this problem, a is 12 feet, and b is 10 feet. Plugging these values into the equation, we get 122 + 102 = c2. Solving for c, we get that the length of the slide is 14.04 feet to the nearest tenth of a foot.
