What are the values of the domain in the following graph?
A.the domain is represented by cm/ year
b. The domain is represented by the height of the horse
c. The domain is represented by the age
d. The domain is represented by the average growth of the horse
Answer:
We conclude that The domain is represented by age.
Thus, the option 'c' is true.
Step-by-step explanation:
We know that the domain of a function is the entire set of input values of the independent variable 'x' for which the function remains real and defined.
Given the attached graph, we can observe that height is dependent on age (years). In other words, the age (years) is basically an independent variable.
Therefore, we conclude that The domain is represented by age.
Thus, the option 'c' is true.
Answer:
C. The domain is represented by the age
Step-by-step explanation:

D. Robertas boat was farther from the dock at the beginning, and it traveled more quickly
I'll give u 5 stars if you right
Answer:
C
Step-by-step explanation:
John:
y = x +30
y = 5x + 50
Roberta:
y = 5x + 2
Conclusion:
You can see that John's boat was farther from the start and traveled faster because when John traveled for 5 hours, he traveled 50 miles while Roberta only traveled 25 miles for the same time.
Hello There!
Your correct answer is C.
There is no way to explain but when I put A it is incorrect but when I read that it was wrong I wanted to let other people that it was incorrect. Thanks!
Hope this helps to all you ape.x learners!!

Number 3.
In the diagram, AB is the tangent to the circle at P and PX is the diameter.
Given that BPQ = 42°, find PQX, PXQ and XPQ.
Answer:
see explanation
Step-by-step explanation:
∠ PQX = 90° ( angle in a semicircle )
∠ PXQ = 42° ( alternate angle theorem )
Angle between tangent and diameter is right, thus
∠ XPQ = 90° - 42° = 48°

A cereal box manufacturer changes the size of the box to increase the amount of cereal it contains. The expressions 16+6.2n and 10+6.5n, where n is the number of smaller boxes, are both representative of the amount of cereal that the new larger box contains. How many smaller boxes equal the same amount of cereal in the larger box?
Answer:
20 smaller boxes
Step-by-step explanation:
Given
Smaller Box = 10 + 6.5n
Larger Box = 16 + 6.2n
Required
Determine the number of small box in each box
To do this, we simply equate both expressions:
[tex]Smaller\ Box = Larger\ Box[/tex]
[tex]10 + 6.5n = 16 + 6.2n[/tex]
Collect Like Terms
[tex]6.5n - 6.2n = 16 - 10[/tex]
[tex]6.5n - 6.2n = 6[/tex]
[tex]0.3n = 6[/tex]
Make n the subject
[tex]n = 6/0.3[/tex]
[tex]n = 20[/tex]
Hence, there are 20 smaller boxes
What formula do you use to measure the entire length of a diagonal?
Answer:
d² = l² + w² ,
Step-by-step explanation:
You can use the Pythagorean theorem to estimate the diagonal of a rectangle, which can be expressed with the following formula: d² = l² + w² , and now you should know how to find the diagonal of a rectangle explicit formula - just take a square root: d = √(l² + w²) .

A tanker truck fills the gas station's reservoir at the rate of 1212 gallons per minute. If the reservoir was empty and it is now 35 gallons full, how long has the tanker been filling the reservoir? Round your answer to the nearest tenth.
Answer: 2.9 minutes.
Step-by-step explanation:
Given: Rate of filing the tank = 12 gallons per minute
Total volume of reservoir = 35 gallons
Time taken to fill the reservoir = [tex]\dfrac{\text{Total volume of reservoir }}{\text{Rate of filing the tank}}[/tex]
[tex]=\dfrac{35}{12}\approx2.9[/tex]
hence, time taken to fill the reservoir = 2.9 minutes.
Jack and Jillian sell apples at a produce stand. Jillian earns $2 for each bag of apples she sells. At the end of the week, Jack has earned $8 less than Jillian. The following expression shows Jack's earnings:
2x − 8
In the expression, what does the first term represent?
1 Jack's earnings at the end of the week
2 The number of bags of apples Jillian sold
3Jillian's earnings at the end of the week
4 The number of bags of apples Jack sold
We are given that Jack and Jillian sell apples at a produce stand .
We are given that an expression which shows Jack's earning=2x-8
We have to find that first term what represent in the given expression
Jillian earns for each bag of apples she sells=$2
Let Jillian sold number of bags of apples =x
Then ,Jillian earn total at the end of the week =
Jack has earned $ 8 less than Jillian earn
Therefore, total earning of jack=
In the given expression the first term 2x represent the earning of Jillian.
Please I need help Asap I give 30 points if I get it rights the question is in the picture
Answer:
10
Step-by-step explanation:
First, you multiply j and k together. j·k=6·4= 24.
Next, you multiply 24 by 2.5. That is equal to 60.
After that, since j=6, you divide 60 by 6.
That is equal to 10.
Hope this helps!
