Answer:
Starting with the equation:
-2x + 6 = -x^2
First, we can rearrange it to put it in standard quadratic form:
x^2 - 2x - 6 = 0
To complete the square, we need to add and subtract a constant term that will make the left-hand side of the equation a perfect square. The constant we need to add is (b/2)^2, where b is the coefficient of x. In this case, b = -2, so:
x^2 - 2x + 1 - 1 - 6 = 0
The first three terms can be written as a perfect square:
(x - 1)^2 - 7 = 0
Add 7 to both sides:
(x - 1)^2 = 7
Now we can take the square root of both sides:
x - 1 = ±√7
Add 1 to both sides:
x = 1 ± √7
So the solutions to the equation are:
x = 1 + √7 or x = 1 - √7

Find the are of the shaded shape below it has two lines of symmetry (vertical and horizontal) that pass through its centre
Give your answer in cm^2
The area of the shaded shape is 62.5cm^2.
To find the area of the shaded shape, we need to break it down into simpler shapes that we can calculate the area of. From the image, we can see that the shape is composed of a rectangle and two right-angled triangles.
First, we need to find the dimensions of the rectangle. Since the shape has vertical and horizontal lines of symmetry passing through its center, we know that the rectangle is divided into four equal parts.
Therefore, the length of the rectangle is twice the length of one of the triangles, which is 5cm. So, the length of the rectangle is 2 x 5cm = 10cm. The width of the rectangle is also 5cm.
Next, we need to find the area of each of the triangles. We know that the base of each triangle is 5cm, and the height is half of the width of the rectangle, which is 2.5cm. Therefore, the area of each triangle is:
0.5 x base x height = 0.5 x 5cm x 2.5cm = 6.25cm^2
So, the total area of the two triangles is 2 x 6.25cm^2 = 12.5cm^2.
Finally, we can find the area of the shaded shape by adding the area of the rectangle and the area of the triangles:
Area = rectangle area + triangle area = 10cm x 5cm + 12.5cm^2 = 62.5cm^2.

Step-by-step explanation:
Brennan knew his parents had set up their will some years ago. Neither he nor his sister, Maureen, had ever discussed the will with their parents. When both parents passed away, they met with the family lawyer about the will. What they found was that the money their parents had been giving them over the last few years was a gift and part of their estate planning. The gifts reduced the size of the estate to ensure the value of the estate upon their passing would be under the tax-free limit.
Their parents had not really talked with Brennan or Maureen about how the “gift” money they had been receiving would affect their final inheritance. As they listened to
the estate lawyer give them details of their inheritance, they were shocked to learn there was less than what they had thought.
1. Discuss your thoughts on how Brennan’s and Maureen’s parents handled the informationin the will prior to their passing. Should the parents have explained more clearly about the “gift” money and how it affected their inheritance?
2. What responsibility did Brennan and Maureen have to discuss the will with their parents?
3. What experience do you have with a family member’s will? How would you approach
the topic of writing a will with a family member?
Open and clear communication is crucial when discussing estate planning and wills with family members to prevent misunderstandings and hurt feelings.
1. It is understandable that Brennan and Maureen feel shocked and disappointed with the reduced inheritance.
While it is not required for parents to disclose every detail of their estate planning to their children, it would have been helpful if they had discussed the impact of the gifts on their estate and their final inheritance.
Clear communication can prevent misunderstandings and hurt feelings in the future.
2. Brennan and Maureen have a responsibility to discuss the will with their parents. It is essential to have an open and honest conversation about their parents' wishes and intentions to avoid any confusion or disputes in the future.
While it can be uncomfortable to talk about death and inheritance, it is a crucial conversation to have.
3. It can be a difficult and emotional topic to discuss, but it is important to have open communication to ensure that everyone's wishes are respected and honored. It may be helpful to consult with a lawyer or financial advisor to ensure that the will is properly drafted and that everyone's needs are addressed.

Triangle QRS is rotated 180° about the origin.
On a coordinate plane, triangle Q R S has points (negative 4, 1), (negative 4, 4), (2, 1).
What are the coordinates of point S’?
Therefore, the coordinates of [tex]S'[/tex] are [tex](-2, -1)[/tex] .
What are coordinates?A series of numbers called coordinates is used to describe a point's location in a two- or three-dimensional space.
Typically, coordinates in a two-dimensional space are expressed as a pair of integers (x, y), where x denotes the point's horizontal location (also known as the abscissa) and y denotes its vertical position (also known as the ordinate).
Coordinates are commonly expressed as a triplet of numbers (x, y, z) in a three-dimensional space, where x, y, and z stand for the locations along the x, y, and z axes, respectively.
In order to describe the location of objects or points in space, coordinates are often employed in a variety of disciplines, including mathematics, physics, engineering, and computer graphics.
To rotate a point 180° about the origin, we need to negate the x-coordinate and the y-coordinate of the point.
So to find the coordinates of S', we can apply this rule to the coordinates of S:
x-coordinate of [tex]S' = -x-[/tex] coordinate of [tex]S = -(2) = -2[/tex]
y-coordinate of [tex]S' = -y-[/tex] coordinate of [tex]S = -(1) = -1[/tex]

A house is purchased for $313,000 with a 15% down payment. A mortgage is secured at 7% for 25 years. Find the monthly payment.
If house is purchased for $313,000 with a 15% down payment, the monthly payment for the mortgage is $1,906.33.
To find the monthly payment for a mortgage secured at 7% for 25 years on a house purchased for $313,000 with a 15% down payment, we can use the formula for calculating mortgage payments:
P = L[c(1 + c)ⁿ]/[(1 + c)ⁿ - 1]
Where P is the monthly payment,
L is the loan amount (which is the purchase price minus the down payment),
c is the monthly interest rate (which is the annual interest rate divided by 12),
n is the total number of monthly payments (which is the number of years multiplied by 12).
Substituting the given values, we get:
L = $313,000 - 0.15($313,000) = $266,050
c = 0.07/12 = 0.00583
n = 25 x 12 = 300
Plugging these values into the formula, we get:
P = $266,050[0.00583(1 + 0.00583)³⁰⁰]/[(1 + 0.00583)³⁰⁰ - 1]

Marisol is making bracelets and rings to sell at a craft fair She plans to sell each bracelet for $6 and each ring for $8. The craft fair committee charges a $25 fee to sell at the fair, and it costs Marisol $2 to make a bracelet and $4 to make a ring. If Marisol wants to sell at least $600 in jewelry and spend less than $300 for supplies and the fee, which system of inequalities represents the situation? Let b represent the number of bracelets and r represent the number of rings.
The equation that represent the number of bracelets b and the number of rings r is 6b + 8r > 600 and 2b + 4r < 275, hence, option A is correct.
Let b represent the number of bracelets and r represent the number of rings that Marisol makes. Marisol plans to sell each bracelet for $6 and each ring for $8. So the amount she earns from selling bracelets is 6b and the amount she earns from selling rings is 8r.
The craft fair committee charges a $25 fee to sell at the fair. So Marisol's total earnings after paying the fee is 6b + 8r - 25. It costs Marisol $2 to make a bracelet and $4 to make a ring. So the total cost of making b bracelets and r rings is 2b + 4r. To make a profit, Marisol's earnings must be greater than her costs,
6b + 8r - 25 > 2b + 4r
Simplifying this inequality, we get,
4b + 4r > 25
We also know that Marisol wants to sell at least $600 in jewelry. This can be expressed as,
6b + 8r > 600
Finally, Marisol wants to spend less than $300 for supplies and the fee. This can be expressed as,
2b + 4r + 25 < 300
Simplifying this inequality, we get,
2b + 4r < 275
Therefore, the system of inequalities that represents the situation is,
6b + 8r > 600
4b + 4r > 25
2b + 4r < 275
where b represents the number of bracelets and r represents the number of rings that Marisol makes.

Determine the equation of the circle with center (6,-2)containing the point (14,6).
Answer:
(x -6)² +(y +2)² = 128
Step-by-step explanation:
You want the equation of the circle centered at (6, -2) through point (14, 6).
Circle equationThe equation of a circle with center (h, k) and radius r is ...
(x -h)² +(y -k)² = r²
For center (h, k) = (6, -2), we can find the value of r² knowing that it will be the value that lets the point (14, 6) satisfy the equation.
(14 -6)² +(6 -(-2))² = r² = 8² +8² = 128
The circle equation is ...
(x -6)² +(y +2)² = 128
Given v = - 5i + 7j and w = - 1 - j a. Find pro*l_{w}*v b. Decompose v into two vectors v_{1} and v_{2} where v_{1} is parallel to w and v_{2} is orthogonal to w
The value of proᵥᵥv is (-30/37)i + (42/37)j and the decomposed vector v into v₁ and v₂ are 6 + 6j and -5i + j - 6 respectively.
a. To find the projection of w onto v (proᵥᵥw), we can use the formula,
proᵥᵥw = (w · ȳ)ȳ where ȳ is the unit vector in the direction of v.
First, let's find the unit vector in the direction of v,
|v| = √((-5)² + 7²) = √(74)
ȳ = v/|v| = (-5/√(74))i + (7/√(74))j
Next, let's find the dot product of w and ȳ,
w · ȳ = (-1)(-5/√(74)) + (-1)(7/√(74))
w · ȳ = 12/√(74)
Finally, we can find the projection of w onto v,
proᵥᵥw = (w · ȳ)ȳ = (12/√(74))((-5/√(74))i + (7/√(74))j)
(w · ȳ)ȳ = (-60/74)i + (84/74)j
(w · ȳ)ȳ = (-30/37)i + (42/37)j
Therefore, the projection of w onto v is (-30/37)i + (42/37)j.
b. v₁ = ((v · w)/|w|²)w
v₂ = v - v₁ where |w| is the magnitude of w. First, let's find |w|,
|w| = √((-1)² + (-1)²)
|w| = √(2)
Next, let's find v · w,
v · w = (-5)(-1) + (7)(-1)
v · w = -12
Using the formula, we can find v₁,
v₁ = ((v · w)/|w|²)w = (-12/2)(-1 - j)
v₁ = 6 + 6j
Now, finding v₂,
v₂ = v - v₁
v₂ = (-5i + 7j) - (6 + 6j)
v₂ = -5i + (7 - 6)j - 6
v₂ = -5i + j - 6
As a result, the vector v can be divided into two parts: v₁ = 6 + 6j and v₂ = -5i + j - 6, where v₁ is parallel to w and v₂ is orthogonal to w.
