If JM=30 and LM=8, what is KM?

Answers

If side JM = 30 and side LM = 8, the length of side KM is equal to 15.49 units.

How to determine the length of side KM?

In this exercise, we would assign the variable x to the length of side KM. Based on the information provided about triangle JKM and triangle KML, we can logically deduce the following parameters;

Side JL = [(30 + 8) × x]/2

Side JL = 38x/2

Side JL = 19x.

Since point M is the perpendicular bisector of both triangle JKM and triangle KML, the length of side KM can be calculated as follows;

19x = √[(30² + x²)(x² + 8²)]/2

38x = √[(30² + x²)(x² + 8²)]

By taking the square of both sides, we have:

38²x² = (900 + x²)(x² + 64)

38²x² = 900x² + 57,600 + x⁴ + 64x²

38²x² = 964x² + 57,600 + x⁴

(x² - 240)² = 0

x² = 240

x = √240

x = 15.49 units.

Answers

Well, we're just simplifying the fraction.

(2x^2)(y/4).

(2yx^2)/4.

When powers of the same base are being divided, subtract. The numbers are just plain fractions. 6/3 = 2 and 4/16 = 1/4. x^4/x^2 = x^2 and y^2/y = y.

Edit:

2/4 is 1/2.

Answers

Given info:

all sides are equal in the given triangle

It is an equilateral triangle all angles are equal and each angle is equal to 60°

Given angles are 3y° and 2x°

→ 3y° = 2x° = 60°

→ 3y° = 60° and 2x° = 60°

→ y° = 60°/3 and x° = 60°/2

→ y° = 20° and x° = 30°

Therefore, x° = 30° and y° = 20°

Answer:-

The values of x = 30° and y = 20°

Key Knowledge:-

→ If all sides are equal in a triangle then it is an equilateral triangle

In an equilateral triangle,

→ all sides are equal.

→ all angles are equal.

→ all angles are equal to 60°

A psychologist plans an experiment in which subjects draw an object based on a verbal description. For each trial, one person draws, one reads the description, and one records how long it takes to get a successful drawing.

From a group of 8 people, in how many ways can the psychologist select a person to draw, a person to read, and a person to record time?

Answer:

The correct answer is 336.

How many ways can the psychologist select a person to draw, a person to read, and a person to record time?

By using the arrangement calculation formula:

⇒ [tex]A^{3}[/tex][tex]^{8}[/tex]  

⇒ 8 × 7 × 6

⇒ 336

The correct answer is 336.

How do you calculate an arrangement?

Remember that combinations are a way to calculate the total outcomes of an event where the order of the outcomes does not matter. To calculate combinations, we will use the formula NCR = n! / r! * (n - r)!, where n represents the number of items, and r represents the number of items being chosen at a time.

For any of you coding experts. I'm just beginning to take coding seriously and I want to know which coding language is the easiest for beginners. Any tips?​

Answers

Answer:

binary codenis the easiest bro it's just 1 and 0 right?

I believe HTML & MySQL are the easiest coding languages for beginners. If you are a starter you might prefer to take HTML which is comparatively really easy & understandable as well. HTML allows you to create webpages in no time with simple coding & there's no use of binary digits. Moving onto MySQL..this is also easy but it's advanced when compared to HTML. But, the work is more neat & good if you program it through SQL. After mastering both of them you can go for Python / Java, which are hard but it should be ok if you studied the first 2 languages. There's Xojo as well, lesser known but still good.

Lines l and m are parallel lines cut by transversal n. Angle R is measured by (3x +12)° and angle S is measured by (5x +8)°.
What is the measure of angle s?
A-90°
B-108°
C-72°
D-20*

Answers

Answer:

x = 20

Step-by-step explanation:

Lines l and m are parallel so the sum of given angles is = 180

3x + 12 + 5x + 8 = 180 add like terms

8x + 20 = 180 subtract 20 from both sides

8x = 160 divide both sides by 8

x = 20 replace x with 20 in given expression to calculate any measure.

The curve above the graph of a sinusoidal function. It goes through the points (-11,0) and (3,0). Find a sinusoidal function that matches the given graph.if needed you can enter pi=3.1416… as pi in your answer otherwise use at least 3 decimal digits.
F(x)=

Answers

Considering the zeros, the graph for the sinusoidal function is:

[tex]F(x) = \sin{\frac{\pi}{7}(x-3)}[/tex]

The zeros given for the function are: [tex]x = -11, x = 3[/tex].For practicality, we are going to define a sine function, which has a zero at x = 0, so we use shifting.

The sine function is given by:

[tex]F(x) = A\sin{Bx}[/tex]

In which:

The amplitude is A.The period is [tex]T = \frac{2\pi}{B}[/tex].

In this problem:

We suppose an amplitude of 1, thus [tex]A = 1[/tex].The difference between the zeros is 14, so we use a period of 14, thus [tex]T = 14[/tex], and:

[tex]\frac{2\pi}{B} = 14[/tex]

[tex]B = \frac{2\pi}{14}[/tex]

[tex]B = \frac{\pi}{7}[/tex]

Thus:

[tex]F(x) = \sin{\frac{\pi}{7}x}[/tex]

Like this, the zeros are at [tex]x = -14[/tex] and [tex]x = 0[/tex]. We want it at [tex]x = -11, x = 3[/tex], thus, we shift the function 3 units to the right, that is, the function is:

[tex]F(x) = \sin{\frac{\pi}{7}(x-3)}[/tex]

The graph is sketched at the end of this answer, and has the desired behavior, which are points (-11,0) and (3,0).
