is this a function or not pt.3
Answer:
Yes, it is a function.
Step-by-step explanation:
We can determine a relation is a function when the domain is assigned each to one range number. All the domain values are different and all the range values are different which proves that definition. Thus, makes it a function.

Answer:
387,420,489
Step-by-step explanation:
First, evaluate what is in the parentheses. This is equivalent to 729. Now take this number, and cube it (or do 729^3). This is equivalent to 387420489.
The ^ symbol means 'to the power of'.
For example, if you want to raise the number 5 to the power of 4, then you would do 5 ^ (to the power of) 4. Also looks like this: [tex]5^{4}[/tex]

Which of Talia's steps is incorrect? Step 1 is incorrect because it uses a point that is not on the line. Step 2 is incorrect because it uses a point that is not on the line. Step 3 is incorrect because it shows an incorrect ratio for the slope. Step 4 is incorrect because it shows an incorrect substitution of (1, 3) into the point-slope form.
Answer:
Step 3 is incorrect because it shows an incorrect ratio for the slope.
Step-by-step explanation:
The correct question is:
Talia wants to write the equation of the graphed line in point-slope form. These are the steps she plans to use:
Step 1: Choose a point on the line, such as (2, 5).
Step 2: Choose another point on the line, such as (1, 3).
Step 3: Count units to determine the slope ratio. The line runs 1 unit to the right and rises 2 units up, so the slope is .
Step 4: Substitute those values into the point-slope form.
y – y1 = m(x – x1)
y – 3 = (x – 1)
Which of Talia’s steps is incorrect?
Step 1 is incorrect because it uses a point that is not on the line.
Step 2 is incorrect because it uses a point that is not on the line.
Step 3 is incorrect because it shows an incorrect ratio for the slope.
Step 4 is incorrect because it shows an incorrect substitution of (1, 3) into the point-slope form.
Answer:
Step 1 is correct because from the graph, points (1,3) and (2,5) lies on the line so the points can be used to find the slope.
Step 2 is also correct.
Step 3 is incorrect. Slope of a graph is the ratio of vertical change to horizontal change. The vertical change is the rise while the horizontal change is the run, hence slope is the ratio of rise to run.
Since the line runs 1 unit to the right and rises 2 units up, so the slope is 2/1 = 2
Therefore the correct point-slope form is:
y – y1 = m(x – x1)
y – 3 = 2(x – 1)
Step 4 is correct, because i t shows an incorrect substitution of (1, 3) into the point-slope form.

Step-by-step explanation:
In the book,the distance between two planets is given as 4.07×10^¹² kilometres. The speed of light is 1.1×10^⁹ kilometres per hour. Calculate the time taken for light to travel from one of these planets to the other. Give your answer in days and hours.
Answer:
3700hours
154days
Step-by-step explanation:
Speed can be defined as the distance cover per time, it can be expressed as
Speed= distance/ time........eqn(1)
Given:
distance between two planets= 4.07×10^¹²
speed of light = 1.1×10^⁹ kilometres per hour
Time= ??
Then substitute the values into equation (1) we have
Speed= distance/ time
1.1×10^⁹ kilometres per hour= 4.07×10^¹²kilometre/ time
Cross multiply, we have
Time= (4.07×10^¹²kilometre) /(1.1×10^⁹ kilometres per hour)
Time= 3700hours.
To convert to day, we know that
60 minute= 1hour
24hour=1day
Time= (3700hour×1day)/24hour
Time= 154days approximately.
Hence, the time taken for light to travel from one of these planets to the other is 154days or 3700hours
Dr. Leo’s new office is 2.8 yards by 4 yards. She plans to run a decorative boarder around the perimeter of the office. How many yards of wallpaper border should she purchase?
Answer:
13.6 yards
Step-by-step explanation:
The equation for perimeter is P=2L+2W
So P=2(4 yards)+2(2.8 yards)
P=13.6 yards
Or you can write the formula as P=L+L+W+W and get the same answer

f (x) = 8x^4 – 64
Factor completely
Answer:
8(x^4 - 8)
Step-by-step explanation:
Factor out an 8, since both 8 and 64 are divisible by 8:
f(x) = 8x^4 - 64
f(x) = 8(x^4 - 8)
So, the equation factored completely is 8(x^4 - 8)
Answer:
[tex]\huge\boxed{f(x)=8(x-\sqrt[4]8)(x+\sqrt[4]8)(x^2+2\sqrt2)}[/tex]
[tex]\huge\boxed{f(x)=8(x-2)(x^2+2x+4)}[/tex]
Step-by-step explanation:
[tex]f(x)=8x^4-64\qquad|\text{distribute}\\\\f(x)=8(x^4-8)=8\bigg[(x^2)^2-\left(\sqrt8\right)^2\bigg]\qquad|\text{use}\ (a-b)(a+b)=a^2-b^2\\\\f(x)=8(x^2-\sqrt8)(x^2+\sqrt8)=8\bigg[x^2-\left(\sqrt[4]8\right)^2\bigg](x^2+\sqrt8)\\\\|\text{use}\ (a-b)(a+b)=a^2-b^2\\\\f(x)=8(x-\sqrt[4]8)(x+\sqrt[4]8)(x^2+\sqrt8)\\\\\sqrt8=\sqrt{4\cdot2}=\sqrt4\cdot\sqrt2=2\sqrt2[/tex]
taking into account the correction from the comment
[tex]f(x)=8x^3-64=8(x^3-8)=8(x^3-2^3)\\\\\text{use}\ a^3-b^3=(a-b)(a^2+ab+b^2)\\\\f(x)=8(x-2)(x^2+(x)(2)+2^2)=8(x-2)(x^2+2x+4)[/tex]

LCM =
Answer:
120
Explanation:
Because I need 20 characters
Answer: The answer to this math question about finding The Least Common Multiple (LCM) of 15 and 8 is 120.
Step-by-step explanation: This is the same thing, according to the online calculator website called, "Calculatorsoup.com", I chose to find the list of the multiples given with the pair of the numbers, so anyways, here are the following steps in order to find The Lowest Common Multiple (LCM) with the given following pairs #15 and #8 are being shown here below:
Find and list multiples of each number until the first common multiple is found. This is the lowest common multiple.1. Here are the list of the multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, 128, 136.
2. Here are the list of the multiples of 15: 15, 30, 45, 60, 75, 90, 105, 120, 135, 150.
So, therefore, the answer to this math question about finding The Lowest Common Multiple (LCM) of the given pair numbers for #15 and #8 is LCM(8, 15) = 120. As always to remember the legends, according to the online calculator website is called, "Calculatorsoup.com", the bold and the underline is being indicated that the first common multiple is founded, and without the given bold and the underline is being indicated that the first common multiple has not been found yet.I hoped that my given answer with my given explanation is very helpful to your own math question about finding The Lowest Common Multiple (LCM) of the given pair numbers, also using my given hint to find the first common multiple is also helpful to your own math question as well according to the online calculator website is called, "Calculatorsoup.com", that's all for today, please mark me as Brainliest and have a rest of a great day! :D

Answer:
a. 300 ≤ m ≤ 350
b. 18,000 ≤ p ≤ 21000
c. no
Step-by-step explanation:
a. If we let m represent the monthly payment, the absolute value equation is ...
|m -325| ≤ 25
-25 ≤ m -325 ≤ 25 . . . . rewrite as a compound inequality
300 ≤ m ≤ 350 . . . . . . . add 325
The range of affordable payments is $300 to $350 per month.
__
b. If financing is for 5 years, that's a total of 5×12 = 60 monthly payments. For a car price of p, the monthly payment is p/60, so the above inequality becomes ...
300 ≤ p/60 ≤ 350
Multiplying by 60 gives the range of affordable car prices:
18000 ≤ p ≤ 21000
An affordable car will have a price between $18,000 and $21,000 (inclusive).
__
c. If the 0% offer is extended to 6 years, the maximum affordable car price can be 6/5 of the upper limit of the range just found:
6/5×$21,000 = $25,200
This is still less than the price of the car you want.
You cannot afford to buy the car you want.
