Thomas is building rectangular boxes. The table shows the area in square feet, f(x), of the bottom of a box when one side of the box is x feet long. Choose the function that represents the data. f(x) = x2 + 2x f(x) = 2x2 f(x) = 2x

Answer:
c
Step-by-step explanation:
A function assigns the values. The correct option is C, f(x)=2x².
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given that the table shows the area in square feet, f(x), of the bottom of a box when one side of the box is x feet long. Now, the function that can represent this table can be found by substituting the values in the function and checking if the two sides are equal or not.
A.) f(x)= x²+2x
f(1) should be equal to 2.
f(x)= x²+2x
f(1)= 1²+2(1) = 3
Thus, this is not the correct function.
B.) f(x)= x²/2
f(1) should be equal to 2.
f(x)= x²/2
f(1)= 1²/2 = 0.5
Thus, this is not the correct function.
C.) f(x)=2x²
f(1) should be equal to 2.
f(x)=2x²
f(1)= 2(1)² = 2
Also, f(2) should be equal to 8.
f(x)=2x²
f(1)= 2(2)² = 8
Thus, this is the correct function.
D.) f(x)=2x
f(1) should be equal to 2.
f(x)=2x
f(1)= 2(1) = 2
Also, f(2) should be equal to 8.
f(x)=2x
f(1)= 2(2) = 4
Thus, this is the correct function.
Hence, the correct function that represents the area of the box is f(x)=2x².

Which equation represents a proportional relationship that has a constant of proportionality equal to –10? y = x minus 10 y = StartFraction over negative 10 EndFraction y = negative 10 x y = negative 10
Answers
Answer:
The correct answer would be C. y = -10x
Step-by-step explanation: We cam eliminate the first two by common sense, that would leave us with options C, and D. The correct answer would be C, the reason it is not D is because D isn't a proportion, y = -10 is just stating that variable y equals -10, whereas, y = -10x represents a proportion.

A milk container is in the shape of a rectangular prism. The width is 26 centimeters, the depth is d centimeters,
and the height is d + 24 centimeters. Write a polynomial that represents the volume (in cubic centimeters) of the
milk container.
Answers
Answer:
Step-by-step explanation:
The milk container has the shape of a rectangular prism. We would determine its volume by applying the formula for determining the volume of a rectangular prism which is expressed as
Volume = length × width × height
From the information given,
Length = height = d + 24 meters
Width = 26 meters
Height = depth = d meters
The polynomial that represents the volume (in cubic centimeters) of the
milk container is
Volume = (d + 24)26d
Volume = 26d² + 624d

Radius = 2cm
Step-by-step explanation:
We reverse equation for volume
V=πr2 h/3 becomes r2= V/( h* 3 *π)
We have height of 6cm so 6*3 = 18 Then V = 72/18π = 4
We then found the square r2 or ^2 or ^2 they are both same answers Radius = 2 as √4 = 2 and 4/2 also is 2
This radius is squared so we use the root √4cm and find r = 2.

x2−3x=−41
Step 2: The coefficient of -3x is -3. Let b=-3.

Each of the 17 guinea pigs needs its cage cleaned. If it takes 1 hour to clean 4 cages, how many hours will it take to clean all 17 cages? It will take hours to clean all the cages.
Answers
Answer:
Time taken to clean all 17 cages = 4.25 hours
Step-by-step explanation:
Total number of Guinea pig cage = 17
Time taken to clean 4 cage = 1 hour
So,
Time taken to clean 1 cage = [tex] \frac{1}{4} [/tex] hour = 15 minutes
Therefore,
Time taken to clean 17 cages = 17 × 15 minutes = 255 minutes
= [tex] \frac{255}{60} [/tex] hours
= 4.25 hours
Answer:
Time taken to clean all 17 cages = 4.25 hours

Answer:
Step-by-step explanation:
In triangles MNP and RSP, if there are two pairs of corresponding angles that are congruent or equal, it means that
triangle MNP is similar to triangle RSP. The corresponding angles in both triangles are
P corresponding to P
M corresponding to R
N corresponding to S
Therefore, the missing piece of information that Javier needs to prove that triangle MNP is similar to triangle RSP by the Angle-Angle Similarity Postulate is
A. Javier needs to know the measure of angle P.
Answer:
D. Javier needs to know that segment MN is parallel to segment SR.
Step-by-step explanation:
(I know this is old, but I wanted to answer if anyone else comes to this.)
If Javier does not know if segment MN is parallel to segment SR, he would not be able to prove that the two triangles were similar.
