Describe how to create the graph of the direct-variation relationship "y varies directly with x where y = -8.4 when x = 4."
Using a proportional relationship, the graph of the proportional relationship [tex]y = -2.1x[/tex] is sketched at the end of this answer.
"y varies directly with x", hence, the equation is modeled by:
[tex]y = ax[/tex]
y = -8.4 when x = 4, hence, we can use it to find a.
[tex]-8.4 = 4a[/tex]
[tex]a = -\frac{8.4}{4}[/tex]
[tex]a = -2.1[/tex]
Hence, the equation is:
[tex]y = -2.1x[/tex]
The graph is sketched at the end of this answer.

What is the approximate length of minor arc XZ? Round to the nearest tenth of a meter. 1.8 meters 3.7 meters 15.2 meters 18.8 meters
Here is the complete question.
[tex]Consider \ circle \ Y \ with \ radius \ 3 m \ and \ central \ angle \ XYZ \ measuring \ 70°. \\ \\ What \ is \ the \ approximate \ length \ of \ minor \ arc \ XZ?\\ \\ Round \ to \ the \ nearest \ tenth \ of \ a \ meter. \\ 1.8 meters \\ 3.7 \ meters \\ 15.2\ meters \\ 18.8 \ meters[/tex]
Answer:
3.7 meters
Step-by-step explanation:
From the given information:
The radius is 3m
The central angle XYZ = 70°
To calculate the circumference of the circle:
C = 2 π r
C = 2 × 3.142 × 3
C = 18.852 m
Let's recall that:
The circumference length define a central angle of 360°
The approximate length of minor arc XZ can be determined as follow:
Suppose the ≅ length of minor arc XZ = Y
By applying proportion;
[tex]\dfrac{18.852}{360} = \dfrac{Y}{70}[/tex]
Y(360) = 18.852 × 70
Y = 1319.64/360
Y = 3.66
Y ≅ 3.7 m

George decides to walk from his home to Tina's house down the street. On the way,
he stops at the gas station to get some snacks. He begins at (2,3), ends at (9,17), and
stops at the gas station at (x,y). If the part to part ratio is 3:4, what is the coordinates
of the gas station? (Type out as a coordinate)
Answer:
The coordinates of the gas station are (5, 9)
Step-by-step explanation:
As given,
George begins at (2,3), ends at (9,17), and stops at the gas station at (x,y). If the part to part ratio is 3:4
A P B
(2, 3) (x, y) (9, 17)
3 : 4
we use the Interval Division formula :
If P(x,y) lies on the interval A(x1,y1), B(x2,y2) such that AP:PB=a:b, with a and b positive, then
x= [tex]\frac{bx1 + ax2}{a + b}[/tex]
y=[tex]\frac{by1 + ay2}{a + b}[/tex]
Here , (x1, y1) = (2, 3)
(x2, y2) = (9, 17)
a : b = 3 : 4
⇒ x= [tex]\frac{bx1 + ax2}{a + b}[/tex] = [tex]\frac{4(2) + 3(9)}{3 + 4} = \frac{8 + 27}{7} = \frac{35}{7} = 5[/tex]
y=[tex]\frac{by1 + ay2}{a + b}[/tex] = [tex]\frac{4(3) + 3(17)}{3 + 4} = \frac{12 + 51}{7} = \frac{63}{7} = 9[/tex]
∴ The coordinates of the gas station are (5, 9)

This is to Represent the point of G.
======================================================
Explanation:
The notation [tex](x,y) \to (x+8, y+5)[/tex] means that we add 8 to the x coordinate and add 5 to the y coordinate. This represents a shift of 8 units to the right and a shift of 5 units up.
Point G is located at (3,5). This means x = 3 and y = 5 pair up together.
Using the translation rule, we get the following
[tex](x,y) \to (x+8, y+5)\\\\(3,5) \to (3+8, 5+5)\\\\(3,5) \to (11, 10)\\\\[/tex]
Point G at the location (3,5) moves to point G' which is at the location (11,10)
The population of a village increased from 234 to 275 during one year. Find the percentage increase?
Answer:
275 is a 17.521% increase of 234.
This is the formula:
(y2 - y1) / y1)*100
y1=start value
y2=end value
The percentage increased population is 17.52 % from 234 to 275 during one year.
What is percentage?Percentage is defined as ratio expressed as a fraction of 100.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that perform arithmetic operation are called arithmetic operators .
Operators which let do basic mathematical calculation
+ Addition operation : Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation : Subtracts right hand operand from left hand operand.
for example 4 -2 = 2
* Multiplication operation : Multiplies values on either side of the operator
For example 4*2 = 8
Given that,
The population of a village increased from 234 to 275 during one year
So, the difference of population is equal to increased population
The difference of population = 275 - 234
The difference of population = 41
Now , the percentage increased population = 41 of 234
The percentage increased population = (41/234)100
The percentage increased population = (0.1752)100
The percentage increased population = 17.52 %
Hence, the percentage increased population is 17.52 % from 234 to 275 during one year

Let $N=2^{10}\cdot 3^5$. What is the smallest positive integer whose product with $N$ is a perfect square?
Answer:
The smallest positive integer is 3.
Step-by-step explanation:
In order to detect if a number is a perfect square, you firstly have to write the number as a product of its prime factor. If the prime factors of the number appear in an even number of times, then it's a perfect square. For example, if we want to detect if 36 is a perfect square we have to write 36 as a product of its prime factors. Doing this, we have:
36 = 2 x 2 x 3 x 3 = 2² x 3². From here, we see that the prime factors of 36 – 2 and 3 – appear twice which is an even number of times. Hence, it's a perfect square.
Now let us go back to our number:
N = 2^10 x 3^5
Obviously, N is not a perfect square because one of it's prime factors, 3, appears 5 times which is an odd number of times. In order to make it a perfect square, we have to multiply it by a certain number of 3's such that it will appear in an even number of times. Since the least positive integer is required, then we have to multiply by the least number of 3 that will make 3^5 even. Obviously, one 3 is the least needed to make 3^5 appear even number of times, because 3^5 x 3 = 3^6.
Therefore we have
N x 3 = 2^10 x 3^5 x 3 = 2^10 x 3^6.

You use 8 fluid ounces of fruit juice in a recipe to make 64 fluid ounces of
fruit punch. A fruit punch you can buy at the store has 10% real fruit juice.
Which has a higher percent of fruit juice??
Answer: Self-made fruit punch
Step-by-step explanation:
Given
when we prepared fruit punch
64 fluid ounces of fruit punch has 8 ounces of fruit juice
i.e. the percentage of fruit juice in fruit punch is [tex]\frac{8}{64}\times100=12.5\%[/tex]
and for the market fruit punch, it has 10% real fruit juice
So, self-made fruit punch has more fluid juice
find the sum of the interior angles of a regular polygon with 14 sides
Answer:
2160°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 14, so
sum = 180° × 12 = 2160°

The mean of the 6 items below is 6. 2 x 2 7 4 12 Find the value of x.
Answer:
9
Step-by-step explanation:
Mean = sum of number / total number
6 = (2 + x + 2 + 7 + 4 + 12) / 6
Multiply both sides by 6
36 = 27 + x
Solve for x
x = 36 - 27 = 9
