Answer:
The function that can be used in the online shopping club about its monthly revenue is:
Step-by-step explanation:
First, we're gonna take into account the different values we have in the exercise:
- 10,000 members
- $7 per month for membership
- Loses of 400 members by each $1 monthly increase
How the variable 
represents the price increase, we can do the formula below:
In this formula, we represent in the first part that by each 1 in the variable , the total of members will be reduced in 400, in the second part, we mention that at the same time, the membership fee will be increased in the same value of . Now we must simplify this function:
We operate the values:
Solve we can:
And organize:
At the end, how 
represents the monthly revenue received by the club, we use that variable for our formula:
<h2>
Hello!</h2>
The answer is:
Center: (-4,-4)
Radius: 2 units.
<h2>
Why?</h2>
To solve the problem, using the given formula of a circle, we need to find its standard equation form which is equal to:
Where:
"h" and "k" are the coordinates of the center of the circle and "r" is its radius.
So, we need to complete the square for both variable "x" and "y".
The given equation is:
So, solving we have:
Now, we have that:
So,
Center: (-4,-4)
Radius: 2 units.
Have a nice day!

Question
What is the diameter of 11.94 cm circumference
Answer:
Soln,
We know that diameter = * 2 radius
radius = 11.94/2= 5.97 half of diameter and when you multiply with 2 ,Then it comes 11.94cm
Now
Step-by-step explanation
Circumference = 2πr
11.94 = 2*22/7*r
11.94 = 6.28r
r= 11.94/6.28
therefore, r= 1.90 cm
Now
We know that diameter = * 2 radius
diameter = 1.90*2 = 3.80 cm
answer checking,
Circumference = 2πr
c= 2*22/7*1.90
therefore c = 11.94 cm
ans proved
plz mark me brainliest and thanks
have a good day ahead ; )
Answer: Choice A
The fractions are not equivalent because the product of the numerator of the first fraction and the denominator of the second fraction is <u> 15 </u> , which is not equal to the product of the numerator of the second fraction and the denominator of the first fraction <u> 16 </u>
===================================================
Explanation:
We have the template 
which cross multiplies to 
So if 
was true, then 
must be true as well, and vice versa.
The left side 3*5 turns into 15, while the right hand side 4*4 becomes 16. The 15 and 16 don't match up.
In short, turns into 
which is a false statement. So the original claim that is also false.
