Answer: c
Step-by-step explanation:
which table could represent a function
The table that could represent a function is given by the values
x = { 1 , 2 , 3 , 4 } and f ( x ) = { 2 , 4 , 6 , 2 } where the there exists one value in the range for every domain value.
What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as f ( x )
Now , the values of x are given as
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
So , when x = { 1 , 2 , 3 , 4 }
The values of f ( x ) should be distinctive and no values of x should have different values for f ( x )
And , f ( x ) = { 2 , 4 , 6 , 2 } represents a function
Hence , the function is f ( x ) = { 2 , 4 , 6 , 2 }

Help! This is my math problem
Answer:
Step-by-step explanation:
The problem is that you cannot be sure that either triangle (it actually requires both of them) contain a right angle
What you have so far is SSA which is not one of the fundamental congruency triangles. In order to be certain of congruency the angle must be made up of the 2 given sides. You are certain that SAS will produce congruency. You are not so sure of r SSA. There are proofs of this on the internet. I urge you to look into it. Though not long, following it step by step takes a lot of patience. A cup of strong coffee is a good idea.
An architect is recreating the blueprint for a deck with an existing scale factor of 1 in. equals 2 ft, that is shown. The architect is using a different scale so that the length of the same deck on the new blueprint measures 8 inches. Complete parts a and b. What is the scale factor of the new blue print? 1 inch = ______feet.
Part 2: What is the width of the deck on the new blueprint?
Answer:
[tex](a)\ k_2 = 1in:3ft[/tex]
[tex](b)\ Scale\ width =\frac{16}{3}\ in[/tex]
Step-by-step explanation:
Given
[tex]k_1 = 1in : 2ft[/tex] --- Initial scale factor
[tex]Blueprint: 12in\ by\ 8in[/tex] --- Missing from the question
Solving (a): The new scale factor.
Convert the initial blueprint to actual measurement using the initial scale factor, we have:
[tex]Length = 12 * 2ft = 24ft[/tex]
[tex]Width = 8 * 2ft = 16ft[/tex]
From the question, we understand the new scale factor represents the width as 8in.
The scale factor (k2) is then calculated as:
[tex]k_2 = \frac{Scale\ length}{Actual\ length}[/tex]
[tex]k_2 = \frac{8in}{24ft}[/tex]
Simplify
[tex]k_2 = \frac{1in}{3ft}[/tex]
Represent as fraction
[tex]k_2 = 1in:3ft[/tex]
The above is the new scale factor
Solving (b): The new width
Using the scale factor above we have:
[tex]k_2 = \frac{Scale\ width}{Actual\ width}[/tex]
[tex]\frac{1in}{3ft} = \frac{Scale\ width}{16ft}[/tex]
The 16 is gotten from:
[tex]Width = 8 * 2ft = 16ft[/tex]
So, we have:
[tex]Scale\ width = 16ft * \frac{1in}{3ft}[/tex]
[tex]Scale\ width = 16 * \frac{1in}{3}[/tex]
[tex]Scale\ width =\frac{16\ in}{3}[/tex]
[tex]Scale\ width =\frac{16}{3}\ in[/tex]
Hence, the scale width of the blueprint is: 16/3 inches
Answer: Part A is 3 and part b is 5 1/3 inches

Soham's video game system measures 8 inches long, 6 inches wide, and 2 inches tall. Sean's video game system measures 1 inch longer on all sides. What is the combined volume of the two game systems?
Answer:
Combined volume of the two game systems [tex]=416[/tex] cubic inches
Step-by-step explanation:
Volume of a cuboid = length × breadth × height
Soham's video game system measures 8 inches long, 6 inches wide, and 2 inches tall.
So,
Volume of Soham's video game system = 8 × 6 × 2 = [tex]96[/tex] cubic inches
As Sean's video game system measures 1 inch longer on all sides,
the video game system measures [tex]8+2=10[/tex] inches long, [tex]6+2=8[/tex] inches wide, and [tex]2+2=4[/tex] inches tall.
Volume of the video game system = 10 × 8 × 4 = [tex]320[/tex] cubic inches.
Therefore,
Combined volume of the two game systems = [tex]96+320=416[/tex] cubic inches

Is 0.3 the multiplicative inverse of 3 1/3? Why or why not?
Chapter : Rational Numbers
Answer:
3 1/3 = 10/3
0.3 = 3/10
a * 1/a =1
then 1/a is multiplicative inverse of a
0.3* 3 1/3 = 3/10 * 10/3 =1
0.3 is multiplicative inverse of 3 1/3
Step-by-step explanation:
Answer:
3 1/3 = 10/3
10.3 = 0.3 = 3 1/3
x * 1/x = 1
∴ yes, the multiplicative reverse of 3 1/3 is 0.3

An object has a mass of 7.2 kg and a density of 0.9 kg/m3.
Find the volume of the object in mº.
Answer:
mass=180kg and the volume=6m³.
then the formula to find density is= mass/volume
using this formula,180kg/6m³=30kg/m³
Answer:
8 m³
Step-by-step explanation:
Let v represent the volume. Recall that density is mass/volume, which here is 0.9 kg/m³. To find the volume of this object, divide the density into the mass:
7.2 kg
--------------- = 8 m³
0.9 kg/m³

Everything must add up to 180
180= 6x - 6 + 7x + 1 +55
Step 2
Combine everything
6x + 7x = 13x
-6 + 1 +55 =50
180 = 13x + 50
Step 4
Subtract. 180 -50
130 = 13x
Step 5
Divide 130/13
X=10
6(10) -6 = 54

Car rental agencey a charges $50 per day plus 10 cents per mile driven agency b charges $20 per day plus 30 cents per mile driven for a one day rental it is cheaper to rent from ange a if you drive more
Answer:
D) 150 miles.
Step-by-step explanation:
The computation is shown below:
Given that
The Cost of the car rental agency of A is $50 + 0.10 per mile
The Cost of the car rental agency of B is $20 + 0.30 per mile
Here we assume the per mile be x
Now we equate these equations
SO,
$50 + 0.10x = $20 + 0.30x
$30 = 0.20x
x = 150
SO it would be more than 150 miles
