Answer:

The value of CD is 2√5

Step-by-step explanation:

* Lets describe the figure to know its name

- ABCD is a quadrilateral

∵ BC parallel to AD

∵ BC = 6 units and AD = 8 units

- The quadrilateral which has two parallel sides not equal in length is a

 trapezoid

∴ ABCD is a trapezoid, where BC and AD are its bases

∵ BA perpendicular to AD

∴ BA is the height of the trapezoid

- The area of the trapezoid = 1/2 (base 1 + base 2) × its height

∵ The bases of the trapezoid are BC and AD

∵ BC = 6 and AD = 8

∵ Its area = 28 units²

∴ 1/2 (6 + 8) × height = 28

∴ 1/2 (14) × height = 28

∴ 7 × height = 28 ⇒ divide both sides by 7

∴ height = 4

∵ The height is BA

∴ BA = 4 unit

- To find the length of CD draw a perpendicular line from C to AD and

 meet it at E

∵ BA and CE are perpendicular to AD

∴ BA // CE

∵ BC // AD

- Perpendicular lines between parallel lines are equal in lengths

∴ BA = CE and BC = AE

∵ BA = 4 and BC = 6

∴ CE = 4 and AE = 6

∵ AD = 8 units

∵ AD = AE + ED

∴ 8 = 6 + ED ⇒ subtract 6 from both sides

∴ ED = 2 units

- In ΔCED

∵ m∠CED = 90°

∴ CD = √[(CE)² + (ED)²] ⇒ Pythagoras theorem

∵ CE = 4 and ED = 2

∴ CD = √[(4)² + (2)²] = √[16 + 4] = √20 = 2√5

* The value of CD is 2√5

Final answer:

The value of the unknown side CD in quadrilateral ABCD can be found using the area of a trapezoid formula and the Pythagorean theorem. Given the area, and the lengths of BC and AD, we calculated that CD equals 8 units.

Explanation:

The student has asked to find the value of CD in a quadrilateral ABCD, where BC is parallel to AD, BA is perpendicular to AD, the area of quadrilateral ABCD is 28 square units, BC is 6 units, and AD is 8 units.

Since BA is perpendicular to AD and BC is parallel to AD, we can determine that ABCD is a trapezoid with AB and CD as the non-parallel sides. The area of a trapezoid is given by the formula Area = ½ × (sum of parallel sides) × height. So we have:

½ × (AD + BC) × height = 28
½ × (8 + 6) × height = 28
½ × 14 × height = 28
7 × height = 28
height = 4 units

Since BA is perpendicular to AD, and given BA is the height of the trapezoid, this means that AB = 4 units. Now, because ABCD has right angles at A and B, triangles ABD and ABC are right triangles and we can use the Pythagorean theorem to calculate CD.

In triangle ABD:

Since CD is the hypotenuse of triangle ABD:

Therefore, the correct answer is CD = 8 units.

Answer:

y=68(1.5)^(x-1)

Step-by-step explanation:

Answer:

The function is:

[tex]y = 68 (1.5) ^ x[/tex]

Step-by-step explanation:

Note that the number of people increases by a factor of 1.5 per hour, and the initial number of people is 68.

So:

 After an hour the number of people is:

[tex]y = 68 (1.5)[/tex]

After two hours the number of people is:

[tex]y = 68 (1.5) (1.5) = 68 (1.5) ^ 2[/tex]

After x hours the number of people is:

[tex]y = 68 (1.5) ^ x[/tex]

Therefore, the exponential growth function that models the number of people y at the fair after x hours is:

[tex]y = 68 (1.5) ^ x[/tex]

Answer:

option D) (x,y,z)

The three-dimensional Cartesian coordinate is defined by three axes at right angles to each other, forming a three dimensional space.

The three axes are labeled x ,y and z.

The x-axis is called abscissa

The  y-axis is called ordinate

The z-axis is called applicate

therefore

A point in a three-dimensional Cartesian coordinate is represented by (x,y,z)

Final answer:

To find the garden's width, factor the area trinomial to match the given length of the garden. The width is represented by the other factor, which in this case is g - 6.

Explanation:

The area of a garden is given by the trinomial [tex]g^2[/tex] - 2g - 24, and the garden's length is g + 4. To find the garden's width, we need to factor the trinomial such that it is the product of two expressions, one of which must be the length (g + 4).

Factoring [tex]g^2[/tex] - 2g - 24, we look for two numbers that multiply to -24 and add up to -2. These numbers are -6 and +4. So, we can factor the area trinomial as:

(g - 6)(g + 4) = [tex]g^2[/tex] - 2g - 24.

Since the length of the garden is g + 4, the other factor, g - 6, must represent the width of the garden. Thus, the garden's width is g - 6.

Answer:

Filling in the blanks: (rectangular prism) (cylinder) (rectangular prism)

The cylinder has the greater volume because the cylinder fits within the rectangular prism with extra space between the two figures.

A prism is a three-dimensional object.

There are triangular prism and rectangular prism.

We have,

We can see this by comparing the formulas for the volumes of the two shapes.

The volume V of a rectangular prism with length L, width W, and height H is given by:

V = L x W x H

The volume V of a cylinder with radius r and height H is given by:

V = πr²H

Now,

We are told that the length of each side of the prism base is equal to the diameter of the cylinder.

Since the diameter is twice the radius, this means that the width and length of the prism base are both equal to twice the radius of the cylinder.

So we can write:

L = 2r

W = 2r

Substituting these values into the formula for the volume of the rectangular prism, we get:

V prism = L x W x H

V prism = 2r x 2r x H

V prism = 4r²H

Substituting the radius and height of the cylinder into the formula for its volume, we get:

V cylinder = πr^2H

To compare the volumes,

We can divide the volume of the cylinder by the volume of the prism:

V cylinder / V prism = (πr²H) / (4r²H)

V cylinder / V prism = π/4

π/4 is greater than 1/1,

Thus,

The cylinder has a greater volume.

The cylinder fits within the rectangular prism with extra space between the two figures because the cylinder is inscribed within the prism, meaning that it is enclosed within the prism but does not fill it completely.

Step-by-step explanation:

18% of 200= 36

200+36=236

200-36=164

Answer:

A. 236

B. 164

Step-by-step explanation:

To solve it first you need to find what 18% of 200 is. To do that take the 18% and make it a decimal % is out of 100, so 18/100 = .18. Then to find how much 18% out of 200 is, multiply .18 * 200. You should get 36. Then you can add and subtract that from 200 to get 18% more and 18% less.

Answer:

Step-by-step explanation:

Before we can determine which measure of central tendency is the best we need to determined whether data set is skewed or not.

We can determine the skewness, if we know at least the median and the mean.

The array of the above data set is,

16,18,28,29,35,36,37,38,40,41,44,66,68,72

The Median of the above array is  

\frac{37 + 38}{2} = \frac{75}{2} = 37.5  

The mean is

\frac{16 + 18 + 28 + 29 + 35 + 36 + 37 + 38 + 40 + 41 + 44 + 66 + 68 + 72}{14} = \frac{532}{14} = 38

Since the mean and the median are not the same, the distribution is skewed.

<b>For a skewed distribution, the best measure of central tendency is the median.</b>

To one decimal place, the median is;

37.5

NB: If the distribution is not skewed then it is normal. In a normal distribution the median is equal to the mean. The mode is considered the best measure of center in this case.

Step-by-step explanation:

The median of a data set is the measure of center that is the middle value when the original data values are arranged in order of increasing (or decreasing) magnitude

Step-by-step explanation:

The solution to the both system of equations A and B are (3.875, 2.375) for system A and (4.133, 2.289) for system B.

Linear equations involve one or more expressions including variables and constants and the highest exponent of the variable is 1.

System of linear equations involve two or more linear equations.

Consider system A.

x + 3y = 11

15x − 3y = 51

Adding both equations,

16x = 62

x = 3.875

3y = 7.125

y = 2.375

Consider system B.

x + 3y = 11

15x = 62 ⇒ x = 4.133

3y = 6.867

y = 2.289

Hence the solutions are (3.875, 2.375) for system A and (4.133, 2.289) for system B.

Answer:

The answer is : 2/3

Step-by-step explanation:

Given is that y varies directly as x.

Means as y increases or decreases, x also increases or decreases.

When y is 6 when x is 72,

So, when x = 8, we have to find y.

We can write the relation as follows:

[tex]\frac{6}{y}= \frac{72}{8}[/tex]

[tex]72y=48[/tex]

[tex]y=\frac{48}{72}[/tex] = [tex]\frac{2}{3}[/tex]

Answer:

y + 8 = 6(x + 1)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = 6 and (a, b) = (- 1, - 8), hence

y - (- 8) = 6(x - (- 1)), that is

y + 8 = 6(x + 1)

ANSWER

[tex]y + 8=6(x + 1)[/tex]

EXPLANATION

The point-slope form of an equation is given by the formula:

[tex]y-y_1=m(x-x_1)[/tex]

Where

[tex](x_1,y_1)[/tex]

is a point on this line and

[tex]m[/tex]

is the slope of the line.

From the question, the line has slope 6 and passes through (-1,-8).

This means that

[tex]x_1=-1[/tex]

[tex]y_1=-8[/tex]

and

[tex]m = 6[/tex]

We substitute these values into the point-slope formula to get:

[tex]y- - 8=6(x- - 1)[/tex]

We simplify to get:

[tex]y + 8=6(x + 1)[/tex]

The equation y = 1 - 2x is represented by this table.

The correct answer is A.

The factorized form of the given polynomial is (3x + 4)(3x - 4). Using one of the factorization methods of polynomial, the result is obtained.

Writing a polynomial as the product of its factors (monomial, binomial or and so on) is called the factorization of the polynomial.

There are different methods of factorization. Some of them are the grouping method, GCF method, the difference of squares method, etc.

The given polynomial is  [tex]9x^2-16[/tex]

Using the difference of squares method we can write the given polynomial as

[tex]9x^2-16 = (3x)^2-(4)^2[/tex]

We know that difference between any two squares is

[tex]a^2-b^2=(a+b)(a-b)[/tex]

So,

[tex]9x^2-16[/tex] = (3x + 4) (3x - 4)

Therefore, the factors of the given polynomial are (3x + 4) and (3x - 4).
