How do you find the table of values on a graph?.
Answers
The table of values on the given graph is for the polynomial y = -x+4.
The example we are using is a polynomial in one variable. It is to be represented graphically. The graph for it is given below.
From this graph, we can clearly see the coordinates of all points we have taken. In order to make the table of values, we need to find the x and y intercepts.
We see that the first point from the left is aligned to the -2 on the x-axis and to the 6 on the y-axis. Similarly, we can identify the following values from the given graph.
x = -2 and y = 6
x = -1 and y = 5
x = 0 and y = 4
x = 1 and y = 3
x = 2 and y = 2
This is the table of values that we found out through the graph.

Constant of Proportionality = 15.20
What's proportionality?
Suppose there are two amounts. Proportionality indicates that if there's a change in the value of one number, the value of other number also changes but maintaining a constant ratio
Proportionality can be direct or inverse
Direct proportion
Two amounts are said to be in direct proportion if on increasing the value of one number, the value of other number also increases and vice versa.
For illustration cost of a commodity and volume of a commodity are in direct proportion
Inverse proportion
Two amounts are said to be in inverse proportion if on increases the value of one number, the value of other volume diminishes and vice versa.
For illustration Number of men and number of days taken by those men to complete a job

Find the number of cube of ide 3cm which can be put into a box which ha internal meaurement of 54cm 40cm and 8 cm
Answers
A total of 640 cubes of 3cm size can fit into a box with internal dimensions of 54, 40, and 8 cm.
By using volume, et’s assume that ’n’ cubes can be cut out from the cuboid. The volume of n cubes will be equal to the total volume of the cuboid.
The volume of 1 cube of side 3 cm is (3)^3 = 27 c.c. [volume of a cube of side 'a' is (a)^3]
Now, the volume of cuboid from which the cubes will be cut is 54 X 40 X 8 = 17280 c.c. [volume of a cuboid is length X breadth X height].
Now, the number of cubes that can be cut out from the cuboid (n) = (volume of cuboid)/(volume of 1 cube) => n = 17280/27 = 640.
Hence, a total of 640 cubes of side 3cm can beput into a box which had internal measurement of 54cm 40cm and 8 cm

the length of a rectangle is 11 less than three times the width, and the area of the rectangle is 42. find the dimensions of the rectangle.
Answers
The dimensions of the rectangle are length and width are 6 and 11.6 respectively.
L = 3w - 11 ,
where,
L = length of the rectangle and
W =width of the rectangle
A=LW
Here A is Area of the Rectangle which is product of its dimensions i.e., length and breadth.
LW = 42
substituting for l:-
(3W-11)W= 42
3W^2 - 11W - 42 = 0
(3W + 10)(W - 6) = 0
W = 6 or -10/3 (ignore the negative root)
So the width is 6 and the length is 70/6= 11.6

Two lines intersecting at a point create vertical angles. Every time they are on an equal footing. Alternatively stated, four angles are created anytime two lines cross or intersect. Two opposed angles are equal and are referred to as vertical angles, as we can see. Due to their position opposite one another, they are also known as "Vertically opposed angles."
Angles that are vertically opposed to one another at a certain vertex are formed by two straight lines intersecting. The equality of the vertically opposed angles has been established.

Here, given that
The experimental volume of liquid is 18.8 ml, and the actual volume of liquid is 18.1 ml

Now, we will calculate the percentage error
So,
percentage error=((Exprimental value-Actual value)/(Actual value))∙100
percntage error=((18.8-18.1))/18.1∙100

a prism is made up of 120 equal cubes. if the volume of the prism is 25, 920 cm3, what is the length of each cube?
Answers
The side of the cube is 6 cm.
What is the Volume of a prism?
The area that a prism takes up is referred to as its volume. A prism is a solid, three-dimensional structure with two identical faces and additional faces that resemble parallelograms. It is a polyhedron whose nomenclature is influenced by the various basic forms. Every prism has a particular base, whether it be a triangular prism (triangular base), square prism (square base), rectangular prism (rectangular base), pentagonal prism (pentagonal base), hexagonal prism (hexagonal base), or an octagonal prism (octagonal base). Consequently, because a prism is a three-dimensional form, its volume likewise exists in a three-dimensional plane. Prisms are measured in terms of their volume in cubic meters, cubic millimeters, cubic inches, or cubic feet. Following are the steps to calculate the prism's volume:
Write down the prism's dimensions as specified in step one.
Step 2: Use the formula V = B H to calculate the prism's volume. V, B, and H stand for the prism's volume, base area, and height, respectively.
Step 3: After obtaining the volume of the prism's value, add the unit of prism volume at the conclusion (in terms of cubic units).
In the question, we have given that:
Prism is made up of 120 equal cubes;
The volume of the prism is 25, 920[tex]cm^{3}[/tex];
So, we can equate the volume of 120 equal cubes with the prism's volume;
⇒ 120 × [tex](a)^{3}[/tex] = 25, 920;
⇒[tex](a)^{3}[/tex] = [tex]\frac{25920}{120}[/tex]
⇒[tex](a)^{3}[/tex] = 216;
So, the value of a is 6 cm;
That is the side of the cube is 6 cm;
Hence, The side of the cube is 6 cm.

The janitor at a school discovered a leak in a pipe. The janitor found that it was leaking at a rate of 12 f oz per minute. How fast was the pipe leaking in gallons per hour?
Answers
Answer:
5.625 gallons are being leaked per hour.
Step-by-step explanation:
Since every fluid ounce = 0.0078125 of a gallon,
0.0078125 x 12 (the amount of fluid ounces leaked per minute) = 0.09375
Since 0.09375 is the number of gallons leaked per minute, we have to multiply by 60 (because an hour is 60 minutes long).
12 x 60 = 720 (the number of fluid ounces leaked per minute)
0.09375 x 60 = 5.625 (the number of gallons are being leaked per hour)

Answers
If the perimeter of the parallelogram is 102 feet, then the value of m is 12.75
The perimeter of the parallelogram = 102 feet

The length of the parallelogram = 3m
The width of the parallelogram = m
Substitute the values in the equation of the perimeter
102 = 2(3m + m)
102 = 2(4m)
102 = 8m
m = 102 / 8

Car 1: Exponential, as there is an equal factor of 16346.6/17390 = 0.94.Car 2: Linear, as there is an equal difference of 1000.Hence the functions are given as follows:
Car 1: c(t) = 17390(0.94)^t. -> initial value multiplied by the equal factor elevated to time.Car 2: c(t) = 17500 - 1000t. -> Initial value subtracted by the equal difference multiplied by time.After nine years, the values are as follows:

where:
b = c^2
a = b^2.
Let's now assign values to c. (here we can start with zero).
If c = 0, then b = 02 = 0 and a = 02 = 0 are the results.
Then N = 0*100 + 0*10 + 0 = 0 (this is not a 3-digit number) is the expression
If c = 1, then b = 12 = 1, then a = 12, and so on.
N = 1*100 + 1*10 + 1 = 111
If c = 2, then b = 2 2 4 a = 4 2 16 will follow.

Given trigonometric expression in algebraic form would be,

In this question, we need write the expression in algebraic form.
Given trigonometric expression is cos(arcsin(x - h/r))
Let y = arcsin(x - h/r)
so, sin(y) = (x - h)/r
By trigonometric identity,
sin^2(y) + cos^2(y) = 1
we have cos(y) = ±√(1 - sin²y)
cos(arcsin(x - h/r)) = ±√[1 - ((x - h)/r)^2]
= ± [√(r² - (x - h)²)]/r
Therefore, given trigonometric expression in algebraic form would be,
cos(arcsin(x - h/r)) = ± [√(r² - (x - h)²)]/r
