Find the equation of a circle centered at (3, -3) and passing through P(3, 0).
Answers
Answer:
(x - 3)² + (y + 3)² = 9
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
the radius r is the distance from the centre to a point on the circle.
given (3, - 3 ) is the centre and (3, 0 ) is a point on the circle
since the x- coordinates of both points are 3 then r is the absolute value of the difference of the y- coordinates, that is
r = | - 3 - 0 | = | - 3 | = 3
then equation of circle is
(x - 3)² + (y - (- 3) )² = 3² , that is
(x - 3)² + (y + 3)² = 9

Answers
The expected value is calculated using the formula:
\(E(X)=\sum xP(x)\)where x represents values of the random variable X and P(x) represents the corresponding probability.
The probability of each number on the face of the tetrahedron being rolled is 1/4. Therefore, the expected value is calculated to be:
\(\begin{gathered} E(X)=1(\frac{1}{4})+3(\frac{1}{4})+5(\frac{1}{4})+7(\frac{1}{4}) \\ E(X)=0.25+0.75+1.25+1.75 \\ E(X)=4 \end{gathered}\)OPTION C is the correct option.

in this problem, it wants us to graph this piecewise function and then determine which answer choice matches. And I'm not sure if you gave me all the answer choices, but let's go ahead and try and graph this. So first we have a vertical line at negative three from negative 22 negative one. So here is -2. It's going to be open circled at negative two, two, which is going to have a closed circle since it's less than or equal to. And it would just connect right in there. Then we would have an open circle at negative one at negative two And then closed at zero And then an open circle at zero and -1 closed at one. So that would be a graph of this function. It doesn't look like I have all the answer choices, which you want to look for, the one that starts at -3. And it's open circle.

Answer: Option A, 192 sqft.
Step-by-step explanation:
The area of a parallelogram is given as A = b * h. Where A = area of a parallelogram, b = base of a parallelogram, and h = height of a parallelogram.
As given in the picture above we can see that the height of the parallelogram is 12 ft and the base is 16 ft.
so Area is the base multiplied by the height. that is A = 16 ft * 12 ft which is equal to 192 ftsq. A parallelogram has for sides and two opposite sides that are parallel and also have equal lengths. The height of a parallelogram is the perpendicular distance between two parallel lines of a parallelogram.
We can use the following equation to find the area of a parallelogram:
\(A=bh\)
b = base lengthh = length from base to base, must be perpendicularSolving the Question
We're given:
b = 16 fth = 12 ftPlug these values into the equation and solve:
\(A=bh\\A=16*12\\A=192\)
Therefore, the area of the parallelogram is 192 ft².

If the function f(x) has a domain of (g,h) and a range of (j,k), then what is the domain and range of g(x) = m(f(x)] + p?
Answers
Answer:
\(Dom\{g(x)\} = Dom\{f(x)\} = (g, h)\).
\(Ran \{g(x)\} = (m\cdot j+p,m\cdot k +p)\)
Step-by-step explanation:
From Mathematics we remember that the domain of a functions corresponds to the set of values of the independent variable (\(x\) in this case) so that images exist and the range of a function is the set of images.
In this case, we know the domain and range of \(f(x)\) and we must find the domain and range of \(g(x)\).
Domain
The domain of \(g(x)\) is the domain of \(f(x)\). That is, \(Dom\{g(x)\} = Dom\{f(x)\} = (g, h)\).
Range
We have to define the bounds of the range of \(g(x)\), given that range \(f(x)\) is modified by streching and horizontal translation operations:
Lower bound (\(f(x) = j\))
\(g(x) = m\cdot j +p\)
Upper bound (\(f(x) = k\))
\(g(x) = m\cdot k +p\)
In consequence, the range of \(g(x)\) is \(Ran \{g(x)\} = (m\cdot j+p,m\cdot k +p)\)

Min-jun deposited $125 in a bank account earning 19% interest,
compounded annually. How much interest will he earn in 48 months?
Answers
Answer: $165.23
Step-by-step explanation:
To solve the problem, we can use the formula for compound interest:
A = P (1 + r/n)^(nt)
where A is the amount, P is the principal (initial amount), r is the annual interest rate as a decimal, n is the number of times the interest is compounded per year, and t is the time in years.
In this case, P = $125, r = 0.19 (since the interest rate is 19%), n = 1 (since the interest is compounded annually), and t = 48/12 = 4 (since the time is given in months but we need to convert it to years). Plugging in these values, we get:
A = 125 (1 + 0.19/1)^(1*4)
A = 125 (1.19)^4
A ≈ $290.23
So, the total amount after 48 months is approximately $290.23. To find the interest earned, we subtract the principal from the amount:
Interest = Amount - Principal
Interest = $290.23 - $125
Interest = $165.23
Therefore, Min-jun will earn $165.23 in interest in 48 months.

At (0, 4), we have
4 = a(0)² + b(0) + c
c = 4
Then the equation is written as,
y = ax² + bx + 4

What are the points of the image of the line in Q4 after the dilation?
Answers
Note that the coordinates of the point A' after rotating 90 degrees clockwise about the point (0,1) are (3, -4). (Option B)
How is this so ?To rotate a point 90 degrees clockwise about a given point,we can follow these steps -
Translate the coordinates of the given point so that the center of rotation is at the origin. In this case,we subtract the coordinates of the center (0,1) from the coordinates of point A (5,4) to get (-5, 3).
Perform the rotation by swapping the x and y coordinates and changing the sign of the new x coordinate. In this case,we swap the x and y coordinates of (-5, 3) to get (3, -5).
Translate the coordinates back to their original position by adding the coordinates of the center (0,1) to the result from step 2. In this case, we add (0,1) to (3, -5) to get (3, -4).
Therefore, the coordinates of the point A' after rotating 90 degrees clockwise about the point (0,1) are (3, -4).

Given: A (-3, 5) and B (4, -2), what is the length of AB?
Answers
After considering the given data we come to the conclusion that the length of AB is 12.124 units, under the condition that A (-3, 5) and B (4, -2) are the given coordinates.
The distance between two points in a plane can be found using the distance formula which is an application of the Pythagorean theorem. The formula is given by d=√ ( ((x₂ – x₁ )² + (y₂ – y₁ )²)
Here (x₁, y₁) and (x₂, y₂) are the coordinates of the two points.
Applying the given coordinates of A (-3, 5) and B (4, -2), we can evaluate the distance between them as follows:
d = √( (4 - (-3))² + (-2 - 5)² )
= √(7² + (-7)²)
= √(98 + 49)
= √147
= 12.124

What is the radius of the circle?
Use 3.14 for \piπpi and enter your answer as a decimal.
Answers
Answer:
The radius of the circle is 24.5 units
Step-by-step explanation:
The formula for the circumference of a circle is \(C=2\pi r\)
Where \(C\) is the circumference and \(r\) is the radius.
Lets solve for \(r\).
Divide both sides of the equation by \(2\pi\).
\(\dfrac{C}{2\pi}=r\)
Now we have an equation to evaluate the radius.
Numerical Evaluation
In this example we are given
\(C=153.86153\\\pi =3.14\)
Substituting our values into our equation for the radius yields
\(r=\dfrac{153.86153}{2*3.14}\)
\(r=\dfrac{153.86153}{6.28}\)
\(r=\dfrac{153.86153}{6.28}\)
