Active reading, mnemonics, practice testing, and spaced repetition are just a few examples of study methods that matrics/Grade 12s can use to study their work more effectively.
What is the study method?Study methods are strategies or techniques that students use to learn and retain information more effectively. Here are four study methods that matrics/Grade 12s could use to study their work more effectively:
1. Active Reading: Active reading is a technique where students actively engage with the text while reading it. This helps students to focus on the most important concepts and better understand the material.
2. Mnemonics: Mnemonics are memory aids that help students remember information by creating an association between new information and something that is already familiar to them.
3. Practice Testing: Practice testing involves creating practice quizzes or tests to help students test their knowledge and identify areas where they need to focus their studying. This technique has been shown to be highly effective in improving memory retention and recall.
4. Spaced Repetition: Spaced repetition involves spacing out study sessions over a longer period of time rather than cramming all the studying into one session. This technique helps students retain information for longer periods of time and can help reduce stress and anxiety associated with last-minute cramming.

How to find the integerThe difference , the sum and the product of two positive integers are in the ratio 1:2:6.Find the integers.
Let x = first integer
y = second integer
Finding x and y;
(x - y): (x + y) : xy = 1:2:6
for : (x-y)/(x+y) = 1/2
cross multiply
2(x-y) = x+y (equation 1)
for: (x+y)/ xy = 2/6 = 1/3
cross multiply
3(x+y) = xy (equation 2)
solve for x and y using equation 1 and equation 2
equation 2: xy= 3(x+y)
xy = 3x + 3y
xy -3y = 3x
y(x-3) =3x
divide both sides by (x-3):
y= 3x/(x-3) (equation 3)
substitute equation 3 to equation 1:
2(x-y) =x+y
2[x-(3x/(x-3))] = (3x/(x-3)) +x
solve for x:
x = 12
using equation 3, solve for y:
y = 3(12)/ (12-3)
y = 4
Check:
difference: 12-4 =8
sum: 12+4 =16

2(a[tex] 2(a^2-4)[/tex]we colored all points of r2 with integer coordinates by one of six colors. prove that there is a rectangle whose vertices are monochro- matic. can we make the statement stronger by limiting the size of the purported monochromatic rectangle?
Yes, we can make the rectangle has sides of length n and n, and all four vertices have the same color
A rectangle is a two-dimensional shape with four sides, two of which are parallel and equal in length, and the other two sides are also parallel and equal in length.
In this case, the objects are the points in the plane with integer coordinates, and the available spaces are the six colors.
Since there are an infinite number of points with integer coordinates and only six colors, it follows that there must be a color that appears at the vertices of a rectangle.
In other words, we can color the points in a manner such that there will be a rectangle in which all four vertices are the same color. This is because, if we divide the points into six different regions, there must be at least one region that contains more points than the others.
When we look for a rectangle, we look for two points in this region that are the farthest apart from each other. The rectangle that connects these two points will have all four vertices the same color.
In conclusion, we can make the statement stronger by limiting the size of the purported monochromatic rectangle.

8 a and b are integers. a+b = 800 b is 250 greater than a. Work out the values of a and b
Answer:a=275 b =525
Step-by-step explanation:
Hi there, here's your answer:
Given:
a and b are integers
a + b = 800 ....(i)
b = a + 250
Putting value of b in (i)
a + (a + 250) = 800

The height of ball which is droped from 2m and rises to 75% after third bounce is equals to the 0.843 meters.
If an object is thrown from high and has a bouncing feature, each bouncing is less than the initial height until it stops. Each bounce reduces the growth rate until it reaches zero. In order to calculate the height of each bounce, so we can estimate what percentage the object will reach after each bounce. If we get the percentage of each bounce, we can easily determine the height of each bounce. We have, a ball is droped from 2 meters and bounce up to 75%. That is height of first bounce is determined by using percentage, height is 2 m × 75% = 2 m×0.75 = 1.5 m

So, the sequence is:
7, 4. 2, 2. 52, 1. 512, 0.9072, 0.54432, 0.326592
Geometric sequenceA geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value. Its general term is. a n= a 1 r n – 1. The value r is called the common ratio. It is found by taking any term in the sequence and dividing it by its preceding term.
The sequence is:
7, 4. 2, 2. 52, 1. 512,.
We have to find the next three terms.
To find r divide the 2nd term by the first:
4.2/7 = 0.6
To check if this is the same ratio for each number divide it by the ratio to get the number before it:
2.52/4.2 = 0.6
1.512/ 2.52 = 0.6
To find the next three terms multiply the last number by the ratio then repeat
(1.512)(0.6) = 0.9072
(0.9072)(0.6) = 0.54432
(0.54432)(0.6) = 0.326592

1 - cos² 15° - cos² 75°
Answer:
1 - cos² 15° - cos² 75° can be simplified as follows:
Using the identity cos² x = 1 - sin² x, we can write the expression as:
1 - (1 - sin² 15°) - (1 - sin² 75°)
= sin² 15° + sin² 75° - 1
Using the identity sin 2x = 2sin x cos x, we can write sin 15° and sin 75° in terms of sin 30° and sin 45°:
sin 15° = sin (30° - 15°) = (1/2) * sin 30°
sin 75° = sin (45° + 30°) = sin 45° + sin 30°
Substituting these values in the above expression, we get:
sin² 15° + sin² 75° = (1/4) * sin² 30° + sin² 45° + sin 30° * sin 45°
= (1/4) * (2 * (1/2)²) + (2 * (1/2) * (1/2)) + (1/2) * (1/2)
= (1/4) + 1/2 + 1/4 = 1
So, 1 - cos² 15° - cos² 75° = sin² 15° + sin² 75° - 1 = 1 - 1 = 0.

The number of units produced does not affect net operating income when using absorption costing.
All production expenses, including direct materials, direct labour, and both variable and fixed overhead costs, are included in the cost of each unit produced in absorption costing. This means that as more units are manufactured, the total manufacturing cost is distributed over a greater number of units, resulting in a reduced cost per unit.
Variable costing, on the other hand, includes only variable production expenses, such as direct materials, direct labor, and variable overhead costs, in the cost of each unit produced. Fixed manufacturing overhead costs are considered period expenses and are not included in the product cost.
