Find the area of a quadrilateral formed by the points of intersection of the graphs f(x) = (x − 3)(x + 1) and g(x) = 4x − 2x^2 + 6 and the points of extrema of f(x) and g(x).
Answer:
24
Step-by-step explanation:
The extrema is halfway between the roots, so for f(x), it has coordinates (1, f(1)) = (1, -4).
For g(x), we can rewrite it as -2(x²-2x-3) = -2(x-3)(x+1). We can see that the extrema has coordinates (1, 8).
Finding the intersection,
[tex](x-3)(x+1)=-2(x-3)(x+1) \\ \\ 3(x-3)(x+1)=0 \\ \\ x=-1, 3 \\ \\ x=-1 \implies f(x)=g(x)=0 \\ \\ x=3 \implies f(x)=g(x)=0[/tex]
So, we need to find the quadrilateral with vertices (1,-4), (1,8), (-1,0), and (3,0).
We observe this is a kite with diagonals of lengths 4 and 12. So, using the formula for the area of a kite, the area is 24.

Which sequence of transformations can joseph perform to show that figure A and figure B are congruent
Step-by-step explanation:
If rigid transformations can be used to map two shapes onto one another, they are said to be congruent (a sequence of one or more rotations, translations, and reflections). Any series of rigid transformations performed on a triangle results in a congruent triangle.
Let's now analyze rigid transformation.
An isometry, also known as a rigid transformation of the plane, preserves length. Reflections, translations, rotations, and combinations of these three transformations are all considered "rigid transformations".
Example: Congruent shapes include, for instance, the right angle triangle and its preimage.

Answer:
[tex] \sf \Large x=−5 [/tex]
Step-by-step explanation:
Let's solve your equation step-by-step.
8x+12=2x−18
Step 1: Subtract 2x from both sides.
8x+12−2x=2x−18−2x
6x+12=−18
Step 2: Subtract 12 from both sides.
6x+12−12=−18−12
6x=−30
Step 3: Divide both sides by 6.
6x/6 = −30/6
x=−5
Step-by-step explanation:
8x + 12 = 2x -18
8x - 2x = -18 - 12
6x = -30
6x/6 = -30÷6

Can a table 9 feet wide (legs folded) fit through a rectangular doorway 4 feet by 8
Yes , it is possible to fit a table 9 feet wide through a rectangular doorway 4 feet by 8.
The Pythagorean theorem states, "In a right triangle, the square of the hypotenuse equals the sum of the squares of the other two sides." The sides of this triangle were called the perpendicular, the base, and the hypotenuse. Here, the hypotenuse is on the opposite side of the 90° angle, so it is the longest side. The sides of a right triangle (a, b, c, etc.) with positive integer squared values are put into the equation, also known as the Pythagorean triple. which is given by [tex]c^2=a^2+b^2[/tex] here “a” is the perpendicular, “b” is the base, “c” is the hypotenuse.A table with folded legs can pass through a rectangular door at an angle of 45°, forming a triangle to which the Pythagorean theorem can be applied.
Let the two sides of the door be the two sides of triangles a and b, then
[tex]c^2=4^2+8^2\\c^2=16+64\\c^2=80\\c=8.94[/tex]
Conclusion: Using the Pythagorean theorem, we know that an 8.94 foot table can pass through the door. And we know that 8.94 ≈ 9
Hence , a 9-feet table can pass through a rectangular door.

I’m not sure if I did it right
Answer:
you did it right!
Step-by-step explanation:
Triangle ABC is an equilateral triangle. Use the figure to find the value of x
The value of x in the equilateral triangle is 10
The equilateral triangle's three characteristics are: Equal on all three sides. The three angles are identical. Three symmetry lines may be seen in the figure. Additionally, each inside angle is identical (60 degrees).
A unique isosceles triangle with three equal sides is called an equilateral triangle. The formulas that we take into account most frequently for a triangle are: Dimensions of an equilateral triangle , the equilateral triangle's circumference, Equilateral triangle's height
An equiangular triangle's area can be calculated using the following formula:
If A=√3a2/4, then ABC's perimeter 3a
where a is the triangle's side length.
In equilateral triangle, the sum of the 3 angles are 180°.then the angle of each side is 60°
From the given data,
(7x-10)°=60°
7x=60+10
7x=70, x=10
Hence the value of x is 10

The length and width of the rectangle with the given perimeter are 26ft and 21ft respectively.
What is the length and width of the rectangle?The perimeter of rectangle is expressed as;
P = 2( l + w )
Given the data in the question;
Let 'x' represent the width of the rectangle.
Width w = xLength = x+5Perimeter = 94ftPlug these values into the equation above.

Find the length of the missing side. Leave your answer in the simplest radical form.
Length of the missing side. Leave your answer in the simplest radical form b= root of 69 feet
Pythagorean theorem:
Pythagorean theorem is the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2
The Pythagorean Theorem is tremendously useful. In many realistic scenarios it is possible to measure a and b with ease, but it is often difficult to measure c. For instance, c might pass through a lake or private property or might be up in the air! We'll do a few example puzzles in class together to show you how this works.
Nonetheless, the Pythagorean Theorem still presents a substantial limitation to utility. Specifically, it requires that the angle between a and b is 90 degrees. If the angle is not 90 degrees, the Pythagorean Theorem doesn't help.
This is where the Law of Cosines comes in. The Law of Cosines allows us to find c even when the angle between a and b is not 90 degrees. Check out this applet which illustrates the relationship between a2 and b2 and c2 that also takes into account the angle C (note the angle is capital C to distinguish it from lower case c, the side opposite angle C) between the legs a and b.
Adjust the blue dots in the triangle on the right right side of the screen to see the relationship. At the outset, when angle C is 90 degrees, a2+b2 is exactly equal to c2. However, when you move any of the three vertices of the triangle, note that the equality is not maintained. The problem is that angle C becomes not 90 degrees.
Now ,
a= 10
c= 13
b=?
a2 + b2 = c2

Rosita paid $32.08, including tax, for her family to eat dinner at a restaurant. She wants to tip a whole dollar amount that is close to 20%. What is a reasonable tip that Rosita should leave?
Answer:
$6
Step-by-step explanation
$32 is the total(100%)
in order to find what she needs to tip, you have to divide by 5 because 100% / 5=20%
now, to find 20% of 32, you divide 32 by 5.
32 you can just round to 30, so that you can divide it by 5.
30/5=$6
you could've rounded the total up to 35, but 30 was closer, therefore $6 was the closest whole number tip rosita could've left.

solve each system of equations by elimination
Answer:
x = [tex]\frac{16}{41}[/tex]
y =[tex]\frac{102}{41}[/tex]
Step-by-step explanation:
To use elimination I need either the x terms to be inverses of each other or the y terms to be inverses of each other. There are a number of ways to do this. I am going to focus on the y's. If I multiple the first equation through by 5 and the second equation through by 3. I will make equivalent equations that will allow the y terms to be eliminated.
14x - 3y = -2
5(14x - 3y) =5(-2)
70x - 15y = -10
4x + 5y = 14
3(4x + 5y) = 3(14)
12x +15y =42
Add together the 2 bold equations above
70x - 15y = -10
12x + 15y = 42
82x = 32 Divide both sides by 82
x = [tex]\frac{32}{82}[/tex] = [tex]\frac{16}{41}[/tex]
Plug this in either equation to solve for y
