What is an example of a unitary method?
A single or distinct unit is referred to by the word unitary. Therefore, the goal of this strategy is to establish values in reference to a single unit. The unitary technique, for instance, can be used to calculate how many kilometers a car will go on one litre of gas if it travels 44 km on two litres of fuel.
How is the unitary method divided?
This can be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees. In order to determine the value of one unit, we essentially divide the total value of a set of items by the number of units. The unitary approach is this.
Given that
Kwai bought 15 lamp for $8.25
$8.25 = 15 lamp
$1 = 15/8.25
$12 = (15/8.25)*12 = 21 approx.
Study up on the unitary technique.

Write the equation for the following relation. P = {(x, y): (1, 0), (2, 4), (3, 8), (4, 12), . . .}
The equation of the relation x and y is y = 4x - 4
How to represent linear equation?The relation follows a linear pattern. Therefore, the relationship is linear.
A linear relationship can be represented in different form such as slope intercept form and point slope form.
Let's represent the equation in slope intercept form.
y = mx + b
where
m = slopeb = y-interceptTherefore,
m = 4 - 0 / 2 - 1
m = 4 / 1
m = 4
Therefore, let's find the y-intercept using (1, 0)

Six trigonometric functions of the angle (20,21)
The exact values of the six trigonometric functions for the point (x, y) = (20, 21) are listed below:
sin θ = 21 / 29, cos θ = 20 / 29, tan θ = 21 / 20, cot θ = 20 / 21, sec θ = 29 / 20, csc θ = 29 / 21
How to determine the exact six trigonometric functions related to a point in rectangular format
Points in rectangular format are points of the form (x, y), where x and y represent the position of the point respect to the origin and along the respective orthogonal axis.
The line segment between the origin and that point represents the hypotenuse of a right triangle. Then, we can determine the six trigonometric functions by using the following formulae:
sin θ = y / √(x² + y²)
cos θ = x / √(x² + y²)
tan θ = y / x
cot θ = x / y
sec θ = √(x² + y²) / x
csc θ = √(x² + y²) / y
If we know that x = 20 and y = 21, then the exact values of the trigonometric functions are:
sin θ = 21 / √(20² + 21²)
sin θ = 21 / 29
cos θ = 20 / √(20² + 21²)
cos θ = 20 / 29
tan θ = 21 / 20
cot θ = 20 / 21
sec θ = √(20² + 21²) / 20
sec θ = 29 / 20
csc θ = √(20² + 21²) / 21

What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written to express proportional relationship as -
y = kx {k is constant}
We have the following system of equation -
3x+y-4z=-22
2x+3y+4z=32
x-y+2z=16
We can write -
x - y + 2z = 16
x = 16 + y - 2z
So, we can write 3x + y - 4z = -22 as -
3(16 + y - 2z) + y - 4z = -22 ...eq[1]
and we can write 2x + 3y + 4z = 32 as -
2(16 + y - 2z) + 3y + 4z = 32 ...eq[2]
Plot eq[1] and eq[2], and find [y] and [z]. Refer to graph.
We get y = 0 and z = 7
So -
x = 16 + 0 - 14
x = 2
Therefore, the values of [x], [y] and [z] are 2, 0 and 7.

Y-4=2/3(×+2) look like on line graph
The graph of the linear equation:
y - 4 = (2/3)*(x + 2)
Can be seen on the image at the end.
How to graph the linear equation?
Here we have the following linear equation:
y - 4 = (2/3)*(x + 2)
Isolating y, we get:
y = (2/3)*(x + 2) + 4
To graph the line, we just need to evaluate it in two different values of x so we get two points, once we get the points, we can graph them on a coordinate axis and then connect them with a line.
If we use x = 1 we get:
y = (2/3)*(1 + 2) + 4
y = (2/3)*3 + 4
y = 2 + 4 = 6
y = 6
Then we have the point (1, 6)
if x = 4 then:
y = (2/3)*(4 + 2) + 4
y = (2/3)*6 + 4
y = 4 + 4 = 8
So we have the point (4, 8)
Then the graph of the linear equation is the one you can see below:

Dimensions 5in x 10in x 10in will yield a box with a max. volume of 500 cubic inches.
Volume = height x length x width
Considering 'x' as the length of the square corners that has been cut out from the cardboard and also, that is height of the cardboard box.
Square corners are cut out so that the sides can be folded up to make a box, cardboard sides would reduce by 2x
Therefore,
V = x (30-2x) (30-2x) --------------------------------- (1)
V=( 30x - 2x²) (30-2x)
V= 900x- 60x² - 60x² + 4x³
V= 4x³ - 120 x²+ 900x
Taking derivative with respect to x:
dV /dx = 12x² - 240 x +900
dV/dx = 4 (3x² - 60x +225)
For maximum dV/dx, make it equal zero
dV/dx = 0
⇒ 4 (3x² - 60x +225)=0
⇒ 3x² - 60x+225=0 (taking 3 common)
⇒ x² - 20x + 75 =0
Solving this quadratic equation, we get,
x² - 15x -5x + 75 =0
x(x-15) - 5(x-15) =0
Either (x-15)=0
x=15
Or, x-5=0
x = 5
If we substitute x = 15 in equation (1), volume becomes zero.
Therefore, x cannot be 15
When x= 5, putting in the equation (1)
V = 5 (30-2(5)) (30-2(5))
V= 5 (10) (10)

what is the probability that at most eight of ten independently selected specimens have a hardness of less than 73.84?
The probability that at most eight of ten independently selected specimens have a hardness less than 73.84 is 0.2639.
Probability:
The chance that a particular event (or set of events) will occur is expressed on a linear scale from 0 (impossibility) to 1 (certainty), also expressed as a percentage between 0 and 100%. The analysis of events governed by probability is called statistics.
Here we have to find the probability:
The probability that each specimen has a hardness less than 73.84 is:
p =Ф( Z< 973.84 - 70)/ 3)
= Ф(Z<1.28 ) = 0.899
P(X<=8) = 1 - P(X=9) - P (X=10)

∠1 ​ and ∠2 are complementary. m∠1=x°m∠2=(3x 30)° what is the value of x? select from the drop-down menu to correctly answer the question.
The value of x is 15
If two angles sum to 90 degrees, they are said to be complimentary angles. In other terms, a right angle is created when two complementary angles are combined (90 degrees). If the sum of angles 1 and 2 equals 90 degrees (i.e., angle 1 plus angle 2 = 90°), then the angles are complementary and are referred to as one another's complements.
∠1 and ∠2 are complementary angles i.e the sum of ∠1 and ∠2 is 90° .
Thus
∠1 + ∠2 = 90°
x° + (3x+30)° = 90°
x + 3x + 30 = 90
4x = 90-30
4x = 60
x = 15
