The perimeter of the quadrilateral is approximately 50.47 units

Given the vertices of the quadrilateral: H(– 4,6), I(4,9), J(2,3), K(7, – 4).

Let us calculate the distances of HI , IJ , JK and KH

[tex]{\displaystyle HI={\sqrt {(4-(-4))^{2}+(9-(6))^{2}}}.}[/tex]

or, HI = 17 units

[tex]{\displaystyle IJ={\sqrt {(2-(4))^{2}+(3-(9))^{2}}}.}[/tex]

or, IJ = 10

[tex]{\displaystyle JK={\sqrt {(7-(2))^{2}+(-4-(3))^{2}}}.}[/tex]

or, JK = √74 = 8.602... ≈ 8.60

[tex]{\displaystyle KH={\sqrt {(7-(-4))^{2}+(-4-(6))^{2}}}.}[/tex]

or, KH = √221 = 14.866... ≈ 14.87

Now perimeter = HI + IJ + JK + KH

or, perimeter = 8.60 + 14.87 + 10 + 17 = 50.47 units.

Therefore the perimeter of the quadrilateral is 50.47 units.

The length of rectangle is (x - 5).

We are given-

Area of rectangle = [tex]x^{3} - 5x^{2} + 3x - 15[/tex]

Width of rectangle = [tex]x^{2} + 3[/tex]

Using the formula, the length will be calculated by rewriting the formula as -

Length = Area/width

Keep the values in formula to find the length of rectangle.

Length = [tex]\frac{x^{3} - 5x^{2} + 3x - 15}{x^{2} + 3}[/tex]

In numerator, separating the common values and rewriting the equation -

Length = [tex]\frac{x^{2} (x - 5) +3 (x - 5)}{x^{2} + 3}[/tex]

Rewriting the equation to for ease of solving to find the length of rectangle -

Length = [tex]\frac{(x^{2} +3)(x - 5)}{(x^{2} +3)}[/tex]

Cancelling [tex](x^{2} + 3)[/tex] as it is common in both numerator and denominator. Now, we will get the value of length of rectangle.

Length = (x - 5)

Hence, the length of rectangle is (x - 5).

The complete question is -

The area of a rectangle is [tex]x^{3} - 5x^{2} + 3x - 15[/tex], and the width of the rectangle is [tex]x^{2} + 3[/tex]. If area = length × width, what is the length of the rectangle? x + 5 x – 15 x + 15 x – 5

Consequently, a hemisphere is a 3D geometric object that is made up of half of a sphere, with one side being flat and the other being a bowl-like shape. It is created by precisely cutting a spherical along its diameter, leaving behind two identical hemispheres.

EXPLANATION; Let ABCDE be the pyramid with ABCD as the square base. Let O and M be the center of square ABCD and the midpoint of side AB respectively. Lastly, let the hemisphere be tangent to the triangular face ABE at P.

Notice that triangle EOM has a right angle at O. Since the hemisphere is tangent to the triangular face ABE at P, angle EPO is also 90 degree. Hence, triangle EOM is similar to triangle EPO.

OM/2 = 6/EP

OM = 6/EP x 2

OM = [tex]6\sqrt{6^2 - 2^2} x 2 = 3\sqrt{2}/2}[/tex]

The length of the square base is thus [tex]2 x 3\sqrt{2}/2 = 3\sqrt{2}[/tex] = A

When two random variables X and Y are considered to be independent, it means that neither X's distribution nor Y's values have any bearing on the other.

A random variable is a variable used in an experiment, such as the number of coin tosses or card draws. An independent random variable is a random variable in your experiment that doesn't affect the other random variables. In other words, it has no impact on the likelihood that another event will occur. For illustration, suppose you randomly selected 50 bags of sugar from various grocery stores in order to determine the average weight of a bag of sugar. The factors are independent since you wouldn't anticipate the weight of one bag having an impact on another. A dependent random variable, on the other hand, does have an impact on the probability of other random variables.

The fence is 33 feet long when measured in yards.

Here,

In order to erect a fence around a rectangular flower garden on his property, Craig has 72 feet of material.

If the fence must be 3 feet in width, then, assuming he uses the entire 72 feet of material, we must determine the fence's length in yards.

What is the rectangle's perimeter?

The rectangle's perimeter is 2 (l + b). l being the length. b=breadth (width).

Now,

A rectangular flower bed should be x feet long.

(Length + Width)2 = the perimeter of a rectangular flowerbed.

72 = 2 (x + 3)

Answer:

The person runs 30km/h or 30000m/h

Step-by-step explanation:

First let's find speed per minute

➟ 1500/3

➟ 500

Now let's calculate speed per hour

1 hour = 60 minutes

➟ 500 × 60

➟ 30,000 meters

If you would like the meters to be in miles

then Formula divide the meter value by 1000

➟ 30000/1000

➟30

∴ The person runs 30km/h or 30000m/h

The speed of the person is 300 km/hour.

Speed is the ratio of distance and time.

It shows how fast an object is moving at a given time.

We have,

Distance covered in 3 minutes = 1500 meters.

1 hour = 60 minutes

3 minutes = 15000 meter

Multiply 20 on both sides.

60 minutes = 300,000 meter

1 km = 1000 meter

Multiply 300 on both sides.

300 km = 300,000 meter

Now,

60 minutes = 300 km

Speed = 300 km/hour

Thus,

300km/hour is the speed of the person.

The statement that is the recursive definition of f is f(1) = -2 f(n) = f(n - 1) + 2  for n > 2

The function definition is given as

f(n) = -4 +2n for n > 1

Start by calculating f(2), f(3) and f(4)

So, we have

f(2) = -4 +2(2)

f(2) = 0

f(3) = -4 +2(3)

f(3) = 2

f(4) = -4 +2(4)

f(4) = 4

In the above computation, we can see that the sequence is an arithmetic sequence with a common difference of 2

So, we have

f(n) = f(n - 1) + 2

Also, we have

f(1) = -4 +2(1)

f(1) = -2

Hence, the statement that is the recursive definition of f is f(1) = -2 f(n) = f(n - 1) + 2  for n > 2

The statement that "In an isosceles triangle, the perpendicular bisector of the base is also the angle bisector of the opposite vertex" is always true

The statement is given as:

In an isosceles triangle, the perpendicular bisector of the base is also the angle bisector of the opposite vertex.

As a general rule;

If any two angles are congruent in a triangle, then it means that the sides that opposite the two congruent angles are congruent sides.

The above is an illustration of the base angle theorem

The base angle theorem goes hand-in-hand with the isosceles triangle theorem which is illustrated by the given statement
