We have proved that quadrilateral ABCD is a square below.

The perimeter of ABCD = 4 × AB

The area of ABCD= (AB)² .

A square is a two-dimensional, four-sided shape with all sides of equal length and all angles of 90 degrees. I

Proof that Quadrilateral ABCD is a Square:

We can prove that quadrilateral ABCD is a square by using the properties of a square.

A square is also a quadrilateral with four equal sides and four right angles.

In the image, we can see that side AB = side CD, and side AD = side BC.

Furthermore, we can see that the angles A, B, C, and D are all right angles=90 degree

This means that the quadrilateral ABCD is a square.

Finding the Perimeter of ABCD:

The perimeter of a square is equal to the sum of its four sides.

In the image, we can see that the sides AB, CD, AD, and BC are all equal. Therefore, the perimeter of ABCD=

4 × AB

= 4 × CD

= 4 × AD

= 4 × BC.

Finding the Area of ABCD:

The area of a square is equal to the length of one of its sides squared. In the image, we can see that the sides AB, CD, AD, and BC are all equal. Therefore, the area of ABCD= (AB)²

= (CD)²

= (AD)²

= (BC)².

Perimeter of ABCD is 4 × AB

The area of ABCD= (AB)².

A square is a two-dimensional, four-sided shape with equal-length edges and 90-degree angles on each side.

The quadrilateral ABCD is a square, therefore:

Using the characteristics of a square, we can demonstrate that the parallelogram ABCD is a square.

A quadrilateral with four equal edges and four right angles is a square.

As seen in the picture, side AB corresponds to side CD and side AD corresponds to side BC.

In addition, we can see that the orientations A, B, C, and D are all 90-degree right angles.

The parallelogram ABCD is a square as a result.

Finding ABCD's Perimeter:

The sum of a square's four edges determines its perimeter.

The sides AB, CD, AD, and BC are equal on the picture, as can be seen. Consequently, the ABCD boundary

4 × AB

= 4 × CD

= 4 × AD

= 4 × BC

Finding the Area of ABCD:

A square's area is equivalent to the square of one of its sides. The sides AB, CD, AD, and BC are equal on the picture, as can be seen.

\(\mathrm{12\sqrt{5} \: \: inches}\)

Step-by-step explanation:

Use Pythagorean theorem, where:

\(a^2+b^2=c^2\)

Substitute in the values.

\(24^2+12^2=c^2\)

\(c^2=576+144\)

\(c^2=720\)

\(c=\sqrt{720}\)

\(c=12\sqrt{5}\)

\(c=26.83281\)

Note that the probability that Y is within 1 standard deviation of its mean value is 0.62.

To calculate V(Y) and sY, we first need to find the expected value of Y:

E(Y) = Σ y P(y)

= (450.05) + (460.1) + (470.12) + (480.14) + (490.25) + (500.17) + (510.06) + (520.05) + (530.03) + (540.02) + (55*0.01)

= 49.15

Next, we can find V(Y) using the formula:

V(Y) = E(Y^2) - [E(Y)]^2

To find E(Y^2), we need to calculate Σ y^2 P(y):

E(Y^2) = (45^20.05) + (46^20.1) + (47^20.12) + (48^20.14) + (49^20.25) + (50^20.17) + (51^20.06) + (52^20.05) + (53^20.03) + (54^20.02) + (55^2*0.01)

= 2433.45

So we have:

V(Y) = 2433.45 - (49.15)^2

= 3.7975

Finally, we can find sY by taking the square root of V(Y):

sY = √(V(Y))

= √(3.7975)

= 1.9487

To determine the probability that Y is within 1 standard deviation of its mean value, we need to find P(49.15 - 1.9487 < Y < 49.15 + 1.9487). Using the probability mass function from the table, we can add up the probabilities of Y taking on values between 47.20 and 51.10:

P(47.20 < Y < 51.10) = P(Y=48) + P(Y=49) + P(Y=50) + P(Y=51)

= 0.14 + 0.25 + 0.17 + 0.06

= 0.62

Therefore, the probability that Y is within 1 standard deviation of its mean value is 0.62.

Answer:

Area of shaded region= 1142.96mm²

Step-by-step explanation:

•First calculate the Area covered by the interior circle.

•To calculate the Area of the exterior circle first add the two radii to get the radius from the centre of the interior circle to the circumference of the exterior circle.

•Use the calculated radius to calculate the Area covered from the centre to the circumference of the exterior circle.

•Now subtract the Area of the interior circle from the area covered by the bigger circle to get the Area of the shaded region.

Answer:

1141.76

Step-by-step explanation:

To solve for the area of the entire circle, we must first solve for the radius. Adding 6 and 14 will get us the total radius of the circle.

Therefore, the radius of the entire circle is 20.

The expression you can use to solve for the area of a circle is:

Inserting the radius into the expression:

Therefore, the area of the entire circle is 400π.

If there is a hole in the circle in the shape of a circle, we must subtract the area of that hole to find the area of the shaded region.

Inserting 6 into the expression to solve for area:

Therefore, the area of the hole is 36π.

Now, we need to subtract the area of the gap from the area of the entire circle.

Because π is approximately equal to 3.14, we can calculate an approximate value for 364π by multiplying 364 by 3.14. This gives us:

Therefore, the area of the shaded region is \(1141.76^{2}\)

y-y1=m(x-x1)

y-(-6)=-1(x-1)

y+6=-x+1

y=-x+1-6

y=-x-5

Answer:

Step-by-step explanation:

Given function:

\(y=\dfrac{x-3}{x^2-2x-3}\)

The domain is the set of all possible input values (x-values).

Factor the denominator of the function:

\(\implies y=\dfrac{x-3}{(x-3)(x+1)}\)

The domain of the given function is restricted as the function is undefined when the denominator equals zero, and when both the numerator and denominator equal zero.  

Therefore, the function is undefined when x = -1 and x = 3.

Therefore, the domain is (-∞, -1) ∪ (-1, 3) ∪ (3, ∞).

The range is the set of all possible output values (y-values).

As the domain is restricted, the range is also restricted.

Therefore, the range is (-∞, 0) ∪ (0, ¹/₄) ∪ (¹/₄, ∞).

A function f(x) is continuous when, for every value \(c\) in its domain:

\(\text{$f(c)$ is de\:\!fined \quad and \quad $\displaystyle \lim_{x \to c} f(x) = f(c)$}\)

Point Discontinuity (holes): When a rational function has a factor with an x that is in both the numerator and the denominator.

Therefore, there is a point discontinuity at x = 3.

Infinite Discontinuity: A vertical asymptote occurs when the denominator of a rational function is zero. This is considered an infinite discontinuity when the graph exists on both sides of the asymptote.

Therefore, there is an infinite discontinuity at x = -1.

Stationary points occur when the gradient of a graph is zero.

Therefore, to find the x-coordinate(s) of the stationary points of a function, differentiate the function, set it to zero and solve for x.

\(\begin{aligned}y & =\dfrac{x-3}{x^2-2x-3}\\\\\implies \dfrac{\text{d}y}{\text{d}x} & = \dfrac{(x^2-2x-3)(1) - (x-3)(2x-2)}{\left(x^2-2x-3\right)^2}\\\\ & = \dfrac{(x-3)(x+1)-(x-3)(2x-2)}{\left((x-3)(x+1)\right)^2}\\\\& = \dfrac{(x-3)[(x+1)-(2x-2)]}{(x-3)^2(x+1)^2}\\\\ & = \dfrac{(x-3)(-x+3)}{(x-3)^2(x+1)^2}\\\\ & = \dfrac{-(x-3)^2}{(x-3)^2(x+1)^2}\\\\& = \dfrac{-1}{(x+1)^2}\end{aligned}\)

\(\begin{aligned}\dfrac{\text{d}y}{\text{d}x} & = 0\\\implies \dfrac{-1}{(x+1)^2} & = 0\\ -1 & \neq 0\end{aligned}\)

Therefore, there are no stationary points and no minimum/maximum points.

\(\textsf{A function is \textbf{increasing} when the \underline{gradient is positive}} \implies \dfrac{\text{d}y}{\text{d}x} > 0\)

\(\textsf{A function is \textbf{decreasing} when the \underline{gradient is negative}} \implies \dfrac{\text{d}y}{\text{d}x} < 0\)

Increasing

\(\begin{aligned}\dfrac{\text{d}y}{\text{d}x} & > 0\\\implies \dfrac{-1}{(x+1)^2} & > 0\\ \dfrac{1}{(x+1)^2} & < 0\\ \textsf{If $\dfrac{1}{a} < 0$ then $a < 0$}:\\(x+1)^2 & < 0\\ \textsf{As $(x+1)^2\geq 0$, no solution.}\end{aligned}\)

Decreasing

\(\begin{aligned}\dfrac{\text{d}y}{\text{d}x} & < 0\\\implies \dfrac{-1}{(x+1)^2} & < 0\\ \dfrac{1}{(x+1)^2} & > 0\\ \textsf{If $\dfrac{1}{a} > 0$ then $a > 0$}:\\(x+1)^2 & > 0\\ \end{aligned}\)

\(\textsf{For $a^n > 0$, if $n$ is even then $a < 0$ or $a > 0$}\)

\(\implies x+1 < 0 \implies x < -1\)

\(\implies x+1 > 0 \implies x > -1\)

Combine the intervals:

(-∞, -1) ∪ (-1, ∞)

Therefore:

\(\textsf{A function is \underline{even} when $f(x) = f(-x)$ for all $x$.}\)

\(\textsf{A function is \underline{odd} when $-f(x) = f(-x)$ for all $x$.}\)

As there is no symmetry about the y-axis (even symmetry) and no origin symmetry (odd symmetry), the symmetry of the function is neither.

Answer:

Domain: (-∞, -1) ∪ (-1, 3) ∪ (3, ∞)

Range: [0, ∞)

Continuity: Point discontinuity (hole) at x = 3.

Infinite discontinuity (vertical asymptote) at x = -1.

None

Decreasing function: (-∞, -1) ∪ (-1, ∞)

Symmetry: Neither

The force acting on the adult and the student, both stuck to the wall, is determined by their weight and the centripetal force acting on them.  This means that the net force acting on both of them must be equal to zero.

The quadratic equation in LaTeX:

$ax^2 + bx + c = 0$

The weight of an object is proportional to its mass, and the centripetal force acting on an object is proportional to its mass and the square of its velocity.

Therefore, the ratio of the force acting on the adult to the force acting on the student will be equal to the square of the ratio of their masses and the square of the ratio of their velocities.

Let the mass of the student be 'm' and the mass of the adult be '2m'. Then, the ratio of the forces acting on them will be (2m) / m * (v_adult / v_student)^2, where 'v' represents velocity.

Since the ride remains stationary against the wall for both the student and the adult, this means that the net force acting on both of them must be equal to zero, i.e. their weight must be balanced by the centripetal force acting on them.

Thus, (2m) / m * (v_adult / v_student)^2 = 1.

This equation shows that the mass of the rider does not determine if the ride will remain stationary against the wall while rotating. The ride's velocity and the distribution of mass on the ride will determine whether it remains stationary or not, not the mass of the rider.

-2 < x ≤ 1

Step-by-step explanation:

First make the fraction into an improper fraction:

Do denominator (bottom number) times the whole number (big number at the front of the fraction) and then plus the numerator (the number at the top)

So for the first one you would do, 3 x 2 = 6

6 + 1 = 7

New fraction = 7/3

Do this for the next fraction:

4 x 1 = 4

4 + 3 = 7

New fraction = 7/4

Now make the denominator the same for both fractions.

Do this by multiplying it by a number to make them the same.

For example here you can multiply 3 by 4, and multiply 4 by 3 to make them both 12.

And remember whatever you do to the denominator, you do to the numerator. So this is our question:

7/3 + 7/4

Multiplying denominators by 3 and 4

7/3 (x4) + 7/4 (x3)

So the new question is:

28/12 + 21/12

Now we can add the new numerators together. leaving the denominators the same.

28 + 21 = 49

Answer = 49/12

To make it a mixed number just divide 49 by 12, until you get a decimal.

You can divide 49 by 12 4 times.

Step-by-step explanation:

The rational function graphed in this problem is defined as follows:

y = -2(x - 1)/(x² - x - 2).

The vertical asymptotes of the rational function for this problem are given as follows:

x = -1 and x = 2.

Hence the denominator of the function is given as follows:

(x + 1)(x - 2) = x² - x - 2.

The intercept of the function is given as follows:

x = 1.

Hence the numerator of the function is given as follows:

a(x - 1)

In which a is the leading coefficient.

Hence:

y = a(x - 1)/(x² - x - 2).

When x = 0, y = -1, hence the leading coefficient a is obtained as follows:

-1 = a/2

a = -2.

Thus the function is given as follows:

y = -2(x - 1)/(x² - x - 2).
