-1/4 will be ration because all fractions are rational
For this case we have that the area of a circle is given by:

Where:
r: It is the radius of the circle
By clearing the radio we have:

We take the positive value:

The diameter is twice the radius:

Answer:

Answer:
The solution is (-2/3,7/3)
Step-by-step explanation:
1) What is the bottom part saying? I will just solve what I see on top since that may be the only part you need to solve, comment what the bottom part is if you need it, I'll help.
2) y=7/3 by solving. for y.
3) x = -4/6 by solving for x after plugging in the y.
4) Your answer is (-2/3,7/3).
I won’t give a actual answer to the equation, because I want you and anyone else to learn it. but I do want to help!
the sum is the answer to a addition problem. that means you should choose anything that falls under that.
The term is anything that is being separated by + or - so for this, choose anything like that.
The product is the final answer to a multiplication problem.
Factor- any number leading up to a answer in a problem. Example: 3 times 4 is 12. The 3 and the 4 are the factors.
Quotient- the final answer to a division problem.
Coefficient- the number separated from the rest of the problem or the number at the beginning of the problem that stands alone. Because this one is a bit harder to explain, I’ll go ahead and tell you it is 4.
Variable- the unknown number such as y or x.
I hope this helps, and good luck!! :)
Answer:
Price demand function
Step-by-step explanation:
The price demand function is the function in which there is a relationship between the demand and the price of the product
The Price demand function is


hence, the price demand function represents that there is a relationship that lies between the demand and the price
