The points (1, 4) and (−3, 2) are the endpoints of a diameter of a circle. What is the equation of the circle?
Answers
Answer:
Step by step
Step-by-step explanation:
Since we have the endpoints of the diameter, the midpoint coordinates of the line segment joining them gives the centre of the circle.
That is, centre (a,b) = ( [1+(-3)]/2, [4+2]/2) = (-1,3)
Distance between the given points give the diameter and half of that is the radius length.
So, radius r = (1/2)* sqrt ( [1-(-3)]^2 + [4–2]^2) = sqrt(5)
Thus equation required is: (x-a)^2 + (y-b)^2 = r^2
So, (x+1)^2 + (y-3)^2 = 5
The equation of the circle is (x + 1)² + (y - 3)² = 5
How to determine the circle equation?The endpoints of the diameter are given as:
(1, 4) and (−3, 2)
Start by calculating the midpoint using:
Midpoint = 0.5 * (x₁ + x₂, y₁ + y₂)
So, we have:
Midpoint = 0.5 * (1 - 3, 4 + 2)
Evaluate
Midpoint = (-1, 3)
So, the center (a,b) of the circle is:
(a,b) = (-1,3)
Calculate the length of the diameter using:
D² =(x₁ - x₂)² + (y₁ - y₂)²
This gives
D² = (1 + 3)² + (4 - 2)²
D² = 20
Take the square roots
D = 2√5
Divide by 2 to calculate the radius
r = √5
Square both sides
r² = 5
The equation of the circle is then represented as:
(x - a)² + (y - b)² = r²
This gives
(x + 1)² + (y - 3)² = 5
Hence, the equation of the circle is (x + 1)² + (y - 3)² = 5

Andy is wrapping gifts for the holidays. He has 3 rolls of wrapping paper that are 18- inches wide and 24- inches long. What is the total area that 3 rolls of wrapping paper could cover?
Answers
Answer:
1296 sq inches
Step-by-step explanation:
To start, you need to get the total area of each individual roll of wrapping paper. To do this, you need to multiply the length x width, which would be 18 x 24 = 432. Then, you have three rolls so you mutiply that by three, which is 432 x 3 = 1296. You add the unit, and that leaves you with 1296 sq inches.
A broken pottery shard found at an archaeological dig has a curved edge. Find the diameter of the
original plate. (Use the fact that the diameter PR is the perpendicular bisector of chord AB.) If necessary,
enter your answer as a simplified proper fraction or mixed number.
Answers
Answer: 18 1/2 inches
Step-by-step explanation:
Applying the segments of chords theorem, the diameter of the original plate is: PR = 18 ⅛ inches.
What is the Segments of Chords Theorem?Based on the segments of chords theorem, the following equation is true:
(AQ)(QB) = (PQ)(QR)
Plug in the values
(9)(9) = (8)(QR)
QR = 81/8
QR = 10 ⅛ inches.
Diameter PR = QR + PQ
Diameter PR = 10 ⅛ + 8
Diameter PR = 18 ⅛

5. The value of a home increases by 7% each year. Explain why the value of the home doubles approximately once each decade.
Answers
Answer:
Step-by-step explanation:

To solve the problem we must know about Compounding.
What is compounding?Compounding is a process where the interest is credited to the initial amount and interest, on the whole, is charged again. and this continues for t period of time.
It is given by the formula,
[tex]A = P(1+r)^t[/tex]
where A is the value after t period of time,
P is the value of the asset at the beginning, and,
r is the rate of interest.
The value of the home doubles once each decade.
Given to us
As it is given that the value of a home increases by 7% each year, therefore, the value of the home is compounding every year.
We know the formula of compounding,
[tex]A = P(1+r)^t[/tex]
Why does the value doubles?Now, let's assume a house whose value is 'P' today, therefore, substitute the value of the house in the formula of compounding,
[tex]A = P(1+r)^t[/tex]
Substitute the rate at which the value is increasing,
[tex]A = P(1+0.07)^t[/tex]
We know that in a decade there are 10 years,
[tex]A = P(1.07)^{10}[/tex]
[tex]A = 1.967P\approx 2P[/tex]
As we can see that the value of the home is almost 2 times the 'P' therefore, twice the value of the home at the beginning.
Hence, the value of the home doubles once each decade.
