which statement best explain best explains whether the table represents a linear or non linear function (100 POINTS) HURRYYYY PLSSS
Answers
Answer:
It is a linear function because there is a constant rate of change in both the input and output values
Step-by-step explanation:
To determine if the function is linear, calculate the differences between the y values.
If the differences are constant, or the same value, the equation is linear and has a constant slope. If the differences are not the same, the equation is not linear.
difference between y values (output)
7 - 4 = 3
3 - 1 = 3
1 - -2 = 3
⇒ the function is linear
difference between x values (input)
-2 - -5 = 3
-5 - -8 = 3
-8 - -11 = 3
⇒ the function is linear as there is a constant rate of change in both the input and output values

What is 40% of a circle of radius 225 feet
Answers
Answer:
About 63,617 ft²
Step-by-step explanation:
[] The area of a circle is equal to πr²
π(225)² ≈ 159,043
[] To find 40%, we can multiply our whole by 40%
-> 40% divided by 100, 0.4, becomes a decimal
159,043 * 0.4 = 63,617
-> Don't forget to add on the units once you are done, this problem was done in feet, since it is an area we used feet squared

The given polynomial can be rewritten as factors of the common ratio of
the geometric progression.
Response:
If a, b, c, d are in GP, (a² + b² + c²) × (b² + c² + d²) = [tex]\underline{(a\cdot b + b \cdot c + c\cdot d)^2}[/tex]
Which method can be used to analyze the given polynomial relation?The assumed parameters are;
a, b, c, and d for a geometric sequence
Therefore;
[tex]\mathbf{\dfrac{b}{a}} = \dfrac{c}{b} = \dfrac{d}{c} = r[/tex]
Which gives;
b = a·r
c = b·r
d = c·r
Therefore;
c = b·r = a·r²
d = c·r = a·r³
(a² + b² + c²) × (b² + c² + d²) = (a² + (a·r)² + (a·r²)²) × ((a·r)² + (a·r²)² + (a·r³)²)
(a² + a²·r² + a²·r⁴) × ((a²·r²) + (a²·r⁴) + a²·r⁶) = a⁴·r²·(r⁸ + 2·r⁶ + 3·r⁴ + 2·r² + 1)
Which gives;
a⁴·r²·(r⁸ + 2·r⁶ + 3·r⁴ + 2·r² + 1) = a²·r·(r⁴ + r² + 1) × a²·r·(r⁴ + r² + 1)
a²·r·(r⁴ + r² + 1) × a²·r·(r⁴ + r² + 1) = (a²·r·(r⁴ + r² + 1))²
a²·r·(r⁴ + r² + 1) = a²·r⁵ + a²·r³ + a²·r
a²·r = a·b
a²·r³ = b·c
a²·r⁵ = c·d
Therefore;
a²·r⁵ + a²·r³ + a²·r = a·b + b·c + c·d
(a² + b² + c²) × (b² + c² + d²) = (a²·r·(r⁴ + r² + 1))² = [tex]\underline{(a\cdot b + b \cdot c + c\cdot d)^2}[/tex]

Diane left a 15% tip for a meal costing $44. What was the amount of the tip? $2. 93 $3. 41 $5. 90 $6. 60.
Answers
The amount left by Diana is percent part of total food cost. The 15% tip of $44 total cost given by Diana is : Option D: $6.60
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
Since the total food cost was $44 and the tip was 15% of the total cost, thus,
[tex]\text{Tip amount} = \dfrac{44}{100} \times 15 = 6.6 \text{\:dollars}[/tex]

Step-by-step explanation:
The cost of the apples is a function of their weight is true about the functional relationship shown in the graph. Correct option is c.
In the graph, the horizontal axis represents the weight (in pounds) of the apples, and the vertical axis represents the cost (in dollars) of the apples. As the weight of the apples increases, the cost also increases. This relationship shows that the cost of the apples is dependent on their weight, making it a functional relationship of "cost as a function of weight."

Which statement is sometimes true:
1. A square is a rhombus
2. A trapezoid is a parallelgram
3. A rectangle is a parallelogram
4. A rectangle is a square
Answers
Answer:
4. A rectangle is a square
Step-by-step explanation:
A rectangle can be a square, but not always. A rectangle has 2 pairs of parallel sides, 2 pairs of congruent sides, and 4 right angles. Squares have 2 pairs of parallel sides, 4 congruent sides, and 4 right angles. So, the difference between the two is that adjacent sides are not necessarily congruent in rectangles, but they are in squares. This means that some rectangles can be a square. If a rectangle has all congruent sides, then it is a square. On the other hand, some rectangles do not have all congruent sides, and thus are not squares.

Multiplying binomials by polynomials btw
Answers
Answer:
2n³ - 3n² - 7n + 3
Step-by-step explanation:
Hi there! Don't worry, polynomials seem hard but you will get them with practice.
I am going to show you 2 methods of multiplying polynomials. These methods are universal, or they work with any polynomial multiplication problem:
Method 1: Distributive PropertyThis is perhaps the most common method. You distribute 1 value to another or multiply each and every single term.
Let's solve it!
(n² - 3n + 1)(2n + 3)n²(2n + 3) - 3n(2n + 3) + 1(2n + 3) n²(2n) + n²(3) - 3n(2n) - 3n(3) + 2n + 3 See how I distributed the values?2n³ + 3n² - 6n² - 9n + 2n + 3Now, we add up like terms. Like terms should have the same coefficient and should be raised to the same power.
2n³ + 3n² - 6n² - 9n + 2n + 3 2n³ - 3n² - 7n + 3There you have it! This is how you solve with The distributive Property Method.
Method 2: Area ModelThis is the next universal method, Area modeling.
Area models can be set up by the number of terms we have. In the first polynomial we have three terms:
n²-3n+1Just for this method, keeping the positive signs helps.
For the binomial, we have two terms (hence, binomial)
2n+3We set up our are model like this, with the terms laid out as side lengths of a rectangle. (Attachment "A")
Next, we find the area of each individual tile. (Attachment "B")
Now, we add like terms. Something nice about area models is that most of the time, the like terms are matched up in a diagonal. (Attachment "C")
2n³ + 3n² - 6n² - 9n + 2n + 3 2n³ - 3n² - 7n + 3We end up with the same answer as before.

An electrician bought 120 feet of electrical wire and used 105 feet of it. What percent of the wire went unused? 15% 12. 5% 8. 75% 7%.
Answers
Answer:
12.5%
Step-by-step explanation:
105 is what percent of 120?
you can use this proportion:
if/of = %/100
in this problem:
is = 105
of = 120
'what percent' = p/100
105/120 = p/100
cross-multiply to get:
120p = 10500
p = 10500/120
p = 87.5
So the electrician used 87.5%, out of 100%, meaning 12.5% went unused
Answer:
The percent of the wire that went unused was 15%.
Step-by-step explanation:
You can set up these equations:
Turn 15% into 0.15
12.5% into 0.125
8.75% into 0.0875
7% into 0.70
Now, the number of wire unused is 15. Since 120 - 105 = 15. So, we can set up these equations to see which percentage it was that got unused:
0.15 x 120 = 18
0.125 x 120 = 15
0.0875 x 120 = 10.5
0.70 x 120 = 84
So, the answer is 15%.

What is distributive property of multiplication over addition?Suppose a, b and c are three numbers. Then we have:
[tex]a(b + c) = a\times b + a\times c[/tex]
(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)
The product result of the given expression is
[tex](2x - 3)(2x^2 + 7x - 1) = 2x(2x^2 + 7x - 1) -3(2x^2 + 7x - 1) \\(2x - 3)(2x^2 + 7x - 1) = 4x^{1+2} + 14x^2 -2x - 6x^2 - 21x + 3\\(2x - 3)(2x^2 + 7x - 1) = 4x^3 + (14 -6)x^2 + (-2 -21)x + 3\\(2x - 3)(2x^2 + 7x - 1) = 4x^3 + 8x^2 -23x + 3[/tex]
It is because when bases are same and there is multiplication, then powers add up, so we have: [tex]a^b \times a^c = a^{b+c}[/tex]
Also, we've
[tex](-ve \times (+ve) = -ve\\(-ve) \times (-ve) = +ve\\(+ve) \times (+ve) = +ve\\(+ve) \times (-ve) = -ve[/tex]
where -ve, +ve are sign of operands and result.
That's why [tex]2 \times -1 = -2[/tex]
