Answers

The sequence of transformations that can be performed on quadrilateral ABCD to show that it is congruent to quadrilateral is 90° counterclockwise rotation about point A followed by the reflection across y axis and a translation 20 units down.

What is transformation?

It should be noted that a transformation simply illustrates the change in shape.

In this case, the sequence of transformations that can be performed on quadrilateral ABCD to show that it is congruent to quadrilateral is 90° counterclockwise rotation about point A.

What is a?


Worth 15 points!

Answers

The solution of the linear equation is a = 11/4.

How to solve the linear equation?

Here we have the linear equation:

9 = 4a - 2

We want to solve this for a, so we need to isolate a on one side of the equation.

First, we can add 2 on both sides to get:

9 + 2 = 4a

11 = 4a

Now we can divide both sides by 4 to get:

11/4 = a

The solution of the linear equation is a = 11/4.

Answers

The value of the relative frequency distribution of the first interval, having a frequency of 14, and the total frequency given is 40, is 0.35.

In a Relative Frequency Distribution, we list how often a data value appears and scale it using the total frequency.

The sum of Relative Frequencies adds to 1.

In the question, we are informed that the first interval has a frequency of 14.

This implies that the data appears 14 times in the first interval.

Also, we are told that the total frequency is 40.

Thus, the relative frequency can be calculated as the ratio of the frequency of the interval to the total frequency.

Therefore, Relative frequency = 14/40 = 0.35.

Thus, the value of the relative frequency distribution of the first interval, having a frequency of 14, and the total frequency given is 40, is 0.35.

What is the root of the polynomial equation x (x minus 2) (x 3) = 18? use a graphing calculator and a system of equations.

Answers

The root of the polynomial equation x (x-2) (x + 3) = 18 is x = 3.

Concept: An expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).

Given:

x (x-2) (x + 3) = 18

Divide both sides of the equation by x:

x (x-2) (x + 3) / x = 18 / x

(x-2) (x) + 3) = 18 / x

You can use the following simultaneous equations.

(1) y = (x-2) (x + 3)

(2) y = 18 / x

The length of one of two chords of a circle is 12 cm. If the chords are 6 cm and 7 cm respectively away from the centre of the circle, calculate the length of the second chord...
Please with explanation ​

Answers

Answer:

2√23 cm or  9.59 cm to the nearest hundredth

Step-by-step explanation:

The 12 cm chord is 6 cm away from the centre and the other chord is 7 cm away from the centre.

If we draw 4 radii from the ends of the 2 chords to the centre  and 2 lines perpendicular from the centre to the 2 chords we have   2 pairs of congruent right triangles.

So by Pythagoras:

r^2 =  6^2 + 6^2   ( the given chord)

r^2 = 7^2 + x^2     where x is 1/2 * length of the second chord.

Therefore:

7^2 + x^2 = 6^2 + 6^2

x^2 = 36+ 36 - 49 = 23

x = √23

and length second chord = 2√23.

What is Addition?

The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.

Given Each employee is paid a minimum wage of $8/hour for an 8-hour day. They are also paid a commission of 12% on all sales they make. Therefore, the expression for the minimum wage can be written as,

Pay for an employee = (8x8) + 0.12(Sales made) = $64 + 0.12(Sales made)

Pay of the first employee = $64 + 0.12($785.96) = $158.32

Pay of the second employee = $64 + 0.12($452.87) = $118.34

Pay of the third employee = $64 + 0.12($616.42) = $137.97

The total wage that is needed to be paid for the day i,

Total = $158.32 + $118.34 + $137.97 = $414.63

Hence, The total wage that Titan needs to pay is $414.63.

Given following:

hypotenuse: 68 meter

---

tan(θ) ratio = opposite/adjacent = 15/8

---

To find ratio of hypotenuse (use Pythagoras theorem):

(hypotenuse)² = (adjacent)² + (opposite)²

(h)² = (8)² + (15)²

h² = 289

h = √289 = 17

The height of the kite above ground is the opposite size.

where:

[tex]\theta[/tex] is the angleO is the side opposite the angleA is the side adjacent the angleH is the hypotenuse (the side opposite the right angle)

The given scenario can be modeled as a right triangle (see attached diagram) where:

θ = angle the thread makes with the groundhypotenuse = thread of the kiteside opposite the angle = the height of the kite above the ground

As we have been given the hypotenuse (thread) and the angle θ, and need to find the height (side opposite the angle), we can use the sine trigonometric ratio.

The angle θ has been given as a tan trigonometric ratio.  

[tex]\sf \textsf{Therefore, if }\tan \theta=\dfrac{15}{8} \textsf{ then } \cos \theta=\dfrac{8}{17} \textsf{ and } \sin \theta = \dfrac{15}{17}[/tex]

[tex]\implies \sin \theta=\sf \dfrac{height}{thread}[/tex]

[tex]\implies \sf \dfrac{15}{17}=\sf \dfrac{height}{68}[/tex]

Answer:

The value of the given sum is 38710

===============

Given

The sum:

7 + 15 + 23 + ... + 767 + 775 + 783

We can notice that:

Subsequence terms have the difference of 8,The first term is 7,The last term is 783.

Since the difference between subsequence terms is same, the terms form an arithmetic progression.

Use the nth term equation to find the number of terms:

aₙ = a₁ + (n - 1)d

Use the given values and find n:

783 = 7 + (n - 1)*88(n - 1) = 776n - 1  = 776/8n - 1 = 97n = 98

Now use the equation for sum of the first n terms of AP:

Sₙ = (a₁ + aₙ)*n/2

Substitute the values and calculate the sum:

S₉₈ = (7 + 783)*98/2 = 790*49 = 38710
