What is the area of a rectangle with vertices at (−3, −1), (1, 3), (3, 1), and (−1, −3)?
Do not round any side lengths
Using the distance formula, the area of the rectangle is: 16 units².
What is the Area of a Rectangle?Area of a rectangle = (length)(width).
Given the vertices:
A(−3, −1)B(1, 3)C(3, 1)D(−1, −3)Area = (AB)(BC)
Apply the distance formula, [tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex], to find AB and BC:
AB = √[(1−(−3))² + (3−(−1))²]
AB = √[(4)² + (4)²]
AB = √32
BC = √[(1−3)² + (3−1)²]
BC = √[(−2)² + (2)²]
BC = √8
Area = (√32)(√8) = √256
Area = 16 units²

Which of the following is the equation for the graph shown?
The equation of an ellipse for the graph shown is [tex]\frac{x^2}{5^2} + \frac{y^2}{21^2} = 1[/tex]
How to determine the equation?Since the given coordinates of the vertices and foci have the form (-5, 0) and (5, 0) and (-2, 0) and (2, 0) respectively, this ultimately implies that the major axis of this ellipse is the x-axis.
Thus, the standard form of the equation of this ellipse is given by:
[tex]\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1[/tex]
Next, we would solve for b² by using this equation:
b² = a² - c²
b² = 5² - 2²
b² = 25 - 4
b² = 21.
Substituting the parameters into the standard equation of an ellipse, we have;
[tex]\frac{x^2}{5^2} + \frac{y^2}{21^2} = 1[/tex]

An 84-foot building casts a 98-foot shadow. What is the angle that the sun hits the building? HINT: Draw a picture.
Answer:
40.6°
Step-by-step explanation:
The building and the shadow are perpendicular to each other (or intersect at a 90° angle).
Meaning that this is a triangle problem.
We are making a triangle from the building to the shadow and a diagonal line connecting the ends of both.
We need to find the angle at the top of the building. The opposite side of the angle is 84. The adjacent side is 98.
Opposite / Adjacent = Tan X
So if we go to the calculator:
[tex]tan^{-1} (\frac{84}{98}) = 40.6[/tex]
The answer is 40.6 degrees.
A triangle has one side length of 2x
2 + 5x + 3. The other two sides of the triangle have lengths x
2 + 2x and
3x − 2. Determine the simplified expression that represents the total perimeter of the triangle.
The simplified expression that represents the total perimeter of the triangle is 2x^2 + 10x + 3
How to determine the perimeter?The side lengths are given as:
2x^2 + 5x + 3, 2 + 2x and 3x - 2
Add these lengths to determine the perimeter (P)
P = 2x^2 + 5x + 3 + 2 + 2x + 3x - 2
Collect like terms
P = 2x^2 + 5x + 2x + 3x + 3 + 2 - 2
Evaluate the like terms
P = 2x^2 + 10x + 3
Hence, the simplified expression that represents the total perimeter of the triangle is 2x^2 + 10x + 3

Step-by-step explanation:
Since you have 6 probabilities that it could be red, you get 1/6. Now, you took 1 probability out of 6, so now you only have 5. So you multiply 1/6 by 1/5. Now you have only 4 cards. Multiply 1/ 6 * 1/5 * 1/4 and keep going (e.g 1/6 * 1/5 * 1/4 * 1/3 * 1/2 * 1). This comes out to 0.00138888888, or rounded to six decimal places, 0.001389.

Use the substitution method to solve the system of equations. Choose the
correct ordered pair.
y = 5x-17
y = x + 3
OA. (5,8)
OB. (4,7)
O C. (1,-12)
OD. (5,-17)
Answer:
A(5 ; 8)
Step-by-step explanation:
y = 5x - 17
y = x + 3
5x - 17 = x + 3
⇔ 5x - x = 3 + 17
⇔ 4x = 20
⇔ x = 20/4
⇔ x = 5
y = 5 + 3 = 8
So (5 ; 8)
Answer:
We can use the substitution method to solve the system of equations.
Since y = x + 3, we can substitute this expression for y in the first equation:
y = 5x - 17
x + 3 = 5x - 17
Subtracting x from both sides, we get:
3 = 4x - 17
Adding 17 to both sides, we get:
20 = 4x
Dividing both sides by 4, we get:
x = 5
Substituting this value of x into either equation, we get:
y = x + 3 = 5 + 3 = 8
Therefore, the correct ordered pair is (5, 8), which corresponds to the point where the two lines intersect.
The correct answer is (A) (5,8).
Which of the following has no inverse?
a) y=√x
b) y=x³
c) y=x²

Which ordered pair would form a proportional retationship with the points in the graph?
4,4
6,9
9,6
8,5
Answer:
(9, 6)
Step-by-step explanation:
the given points are
(3, 2)
(6, 4)
so, can you see, how the sequence continues ?
I see immediately that for every 3 additional units of x we add 2 units of y.
so, yes, the next point in the sequence is
(6 + 3, 4 + 2) = (9, 6).
so, this point (or ordered pair) follows the same ratio or proportional relationship between x and y as the points already in the graph.
in other words, they are on the same line following the same slope ("y coordinate change / x coordinate change" when going from one point on the line to another).

Step-by-step explanation:
The sum of the internal angles of a triangle is 180°

because one pair of congruent corresponding angles is sufficient to determine similar triangles
because both triangles appear to be isosceles, ∠MLN ≅ ∠LMN, and ∠NOP ≅ ∠OPN
Answer: because ∠MNL and ∠ONP are congruent angles
