It should be emphasized that a relationship is proportional if its graph is a line that passes through its origin.
How should the information be illustrated?
If the graph of a connection is a line passing through the origin, the connection is proportionate. If it is not a line or ray that fails to do this, the ratio is not proportional. The equation for the proportionality constant is K = y/x. This is the same equation used to get the slope of a straight line with respect to the origin.
If the graph of a relationship is a line or ray that goes through the origin, the relationship is proportional. If the line or ray does not pass through the origin, it is not proportional. Additionally, if anything is not linear, it is not proportionate.

mrs green wants to use wood to make a fence around her circular garden. Her garden has a radius of 16 feet How much wood will she need to enclose her garden?.
ANSWER
100.5 feet
EXPLANATION
The radius of the circular garden is 16 feet.
To find how much wood she would need to make a fence around the garden, we need to find the circumference of the garden.
Circumference can be found using the formula:
[tex]C\text{ = 2}\pi r[/tex]where r = radius
Therefore:
[tex]\begin{gathered} C\text{ = 2 }\cdot\text{ }\pi\cdot\text{ 16} \\ C\text{ = 100.5 ft} \end{gathered}[/tex]She would need 100.5 ft length of wood to enclose the garden.
What is the scale factor of the dilation?
The scale factor for the square LMNO to L'M'N'O' is k = 1/2.
What is the scale factor of the dilation?Remember that for any length L, a dilation of scale factor k gives a new length L' such that:
L' = k*L
Look at line LM, it has a length:
L = √(6^2 + 2^2) = √40
Now line L'M' has a length:
L' = √(1^2 + 3^2) = √10
Then we can see that:
L' = k*L
√10 = k*√40
√10/√40 = k
√(1/4) = k
1/2 = k
The scale factor is 1/2.

A triangle has side lengths of,x, x+1, and 11. Find each side length when the perimeter is 30 inches
The sides of the triangle whose perimeter is 30 are given by-
[a] = 9 , [b] = 10 , [c] = 11.
What is the perimeter of triangle?
The perimeter of triangle is the sum of its sides. Mathematically -
Perimeter [P] = a + b + c
Given is a triangle whose side measurements are x, x + 1, and 11. The perimeter of triangle is 30 inches.
From the definition of the perimeter of a triangle -
Perimeter = sum of its sides
x + (x + 1) + 11 = 30
x + x + 1 + 11 = 30
2x + 12 = 30
2x = 18
x = 9
Now -
Length of side 1 = [a] = 9
Length of side 2 = [b] = 10
Length of side 3 = [c] = 11
Therefore, the sides of the triangle whose perimeter is 30 are given by-
[a] = 9 , [b] = 10 , [c] = 11.

David buys last year's best-selling novel, in hardcover, for $13.30. This is with a 30% discount from the original price. What was theoriginal price of the novel?
Since the price paid got 30% discount from the original price, so this price represents 70% of the original price.
Using the variable x to represent the original price, we can write the following equation and solve it for x:
[tex]\begin{gathered} 13.3=70\text{\% of x} \\ 13.3=\frac{70}{100}\cdot x \\ 13.3=0.7\cdot x \\ x=\frac{13.3}{0.7} \\ x=19 \end{gathered}[/tex]Therefore the original price is $19.

The standard form of the expression 25×10 to the power of -3 is 2.5×10⁻⁴
What exactly is meant by "scientific notation"?Scientific notation can be employed to reduce exceptionally large figures to positive exponential values, as well as very small figures to negative exponential values.When writing a number in m10n scientific notation, you can use decimal numbers and positive exponents to transform a long number to a shorter one.The Index Power Rule:
According to this formula, when the power of a number is raised to another power, this same indices are multiplied.This is the fourth index law, and it's the Index Law for Powers.For the given expression;
25×10 to the power of -3
This can be written as follows;

The price of the toy on dollars is 5.22.
Here, we are given that a toy costs 35,000 lndonesian rupiah (Rp).
Further, the conversion rate is-
Rp 1000 = $0.145
Now, if 1000 Rp = $0.145 then 1Rp will be = $0.145/1000
= $0.000145
Thus, we get 1Rp = $0.000145
Now, we need to find how much 36,000 Rp is in dollars.
Since, 1Rp = $0.000145, 36,000 Rp will be = $(0.000145 × 36,000)
= 0.145 × 36
= 145/1000 × 36
36 can be written as- (40 - 4)
= 145 (40-4)/ 1000
= {(145 × 40) - (145 × 4)} / 1000
= (5,800 - 580)/1000
= 5,220/1000

The correct statement regarding Isaiah is that A. His gross pay is $3,000 and net pay is $2,500
How to illustrate the information?Before taxes, benefits, and other payroll deductions are taken out of an employee's paycheck, that amount is known as their gross pay. Net pay, often known as take-home pay, is the amount that is left after all withholdings have been taken into account. Determining the number of pay periods you have throughout the year is the first step in calculating the gross compensation for a salaried employee.
The time range for which you pay your employee is known as a pay period. You must first determine your employee's gross compensation before you can determine their net pay. This is where you should start. The next thing you need to know is what payroll deductions your employee receives.
Since the take-home pay is $2,500, this is the net pay.
In conclusion, the correct option is A.

We calculate the average rate of change by dividing the change in y (output) by the change in x. (input). And all we're doing visually is calculating the slope of the secant line that connects two points.Follow these steps to calculate the rate of change on a graph when given two points on the graph:
Determine the coordinates of the given points.Determine the difference in the output values.Determine the difference in the input values.Determine the ratio of the change in y to the change in x: ΔyΔx.Here in the question ,
Given two points (0 , 8400) and (13.333 , 0)
to find the average rate of change ,
Average rate of change = y2 - y1/ x2 - x1
by substituting values,
Average rate of change = 0 - 8400/ 13.333 - 0
= - 8400 / 13.333
= - 630.01 ft/min
since the helicopter is descending the rate of change will be negative
so the rate of change of helicopters height is - 630.015 ft/min
