Answer :
and 
Step-by-step explanation:
Given : A circle with the same radius as the circle shown but with a center at (-1.1).
To find : Which equation represents a circle ?
Solution :
The equation of a circle with center (h,k) and radius r is given by :

Here, we are given (h,k)=(-1,1)
and radius r=4 units
So, equation of circle will be :


or 
Therefore, the required equations of circle are
and 
Answer:
x = 2/3 or x = -2/3
Step-by-step explanation:
Solve for x over the real numbers:
9 x^2 = 4
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides by 9:
x^2 = 4/9
Hint: | Eliminate the exponent on the left-hand side.
Take the square root of both sides:
Answer:x = 2/3 or x = -2/3
Using the asymptote concept, the function with a vertical asymptote at x = 3 and an horizontal asymptote at
is given by:

<h3>What are the asymptotes of a function f(x)?</h3>
- The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.
- The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.
The vertical asymptote at x = 3 means that x = 3 is a root of the denominator, hence:

The horizontal asymptote at y = -1/2 means that:

Which happens if
, hence the function is:

Answer:
1467
Step-by-step explanation:
i know this because taking a negative number and a positive is like adding and then you subtract 144 and you get 1467
