Is 8 10 15 a right triangle?

Answers

Answer 1

NO, A triangle has sides of lengths 8,10, and 15 is not a right triangle.

A right-angled triangle is a triangle with one of the angles at 90 degrees. A 90-degree angle is called a right angle.

The formula states that in a right triangle:

The square of the hypotenuse is equal to the sum of the square of the base and the square of the altitude.

(Hypotenuse)² = (Base)² + (Altitude)²

c²=a²+b²

The three numbers which satisfy the above formula are the Pythagorean triplets

Properties of right angle:

The largest angle is always 90º and called the hypotenuse which is always the side opposite to the right angle.

The measurements of the sides follow the Pythagoras rule, which cannot have any obtuse angle.

consider c=15 a=10, b=8 substitute in above formula:

15²=10²+8²

⇒225=100+64

⇒225[tex]\neq[/tex]164

Therefore, and 8,10,15 is not right triangle.

△BOK∼POS. Identify the coordinates of K and the scale factor.

O = 0, 0

B = 5, 0

P = 8, 0

S = 0, -12

Answers

The coordinates of K = (0, -7.5) and the scale factor is 8/5.

Consider the following figure of triangles.

△BOK and ΔPOS.

Since △BOK∼ ΔPOS, the sides of △BOK and ΔPOS must be in proportion. (from definition of triangle similarity)

i.e., OP / OB = OS / OK = PS/BK

Consider an equation,

OP / OB = OS / OK

From the diagram:

OP = 8, OB = 5, OS = 12

Substitute these values in above equation.

8/5 = 12/OK

OK = 60/8

OK = 7.5

We can observe that OK is the distance of point K from origin 'O'

So, the coordinates of K would be (0, -7.5)

And the scale factor is 8/5.

What is a linear equation?

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

Which graph shows the polar coordinates (−3,−π4) plotted?

Answers

The graph located in the lower right section represents the point with coordinates (r, θ) = (-3, -π/4).

How to chose a graph associated with given polar coordinates

A point in polar form is described by its magnitude and angle in standard position. When magnitude is negative it means that its angle is +π radians than its equivalent with positive magnitude.

Then, we can determine the angle of the resultant point by means of the following expression:

θ⁻ = θ⁺ + π   (1)

Where:

θ⁺ - Angle of the equivalent point with positive magnitude, in radians.θ⁻ - Angle of the equivalent point with negative magnitude, in radians.  

If we know that θ⁺ = -π/4 and r = 3, then the angle of the point in standard position is:

θ⁻ = θ⁺ + π

θ⁻ = -π/4 + π

θ⁻ = 3 · π/4

Hence, the graph located in the lower right section represents the point with coordinates (r, θ) = (-3, -π/4). [tex]\blacksquare[/tex]

On a negatively skewed curve, which is true?
a.The median is lower than the mode which is lower than the mean. b.The mean, median, and mode are the same. c.The mean is lower than the median which is lower than the mode. d.The mode is lower than the mean which is lower than the median. e.The mean is lower than the mode which is lower than the median.

Answers

The mean of negatively skewed data is smaller than the median. If the data are displayed symmetrically, the distribution is not skewed regardless of tail length or thickness. So, option d. is correct.

What do you mean by skewed curve?

A skew curve is a type of statistical distribution in which the data are unevenly distributed. This is often called an asymmetric distribution, meaning that the two halves of the curve look different. A skewed curve can be either positively or negatively skewed, depending on the direction in which the data points are shifted. Positively skewed curves tend to have long tails to the right, while negatively skewed curves tend to have long tails to the left. This type of distribution is common in real-world data such as income and wealth distributions.

A negatively skewed curve is indicated by the negative tail of the chart. This means that the data points are likely to be below average. Therefore, the mean is lower than the mode, which is lower than the median. The mean is the arithmetic mean of all data points, the mode is the most common value, and the median is the midpoint of the data points.

Answer and Step-by-step explanation:

First, solve for y in the second equation because that equation would be easier to solve than the first one for y.

y = 10 - 3x.

Now, plug this into the y of the first equation, and solve for x.

4x + 4(10 - 3x) = 4

Distribute the 4.

4x + 40 - 12x = 4

Combine 4x and -12x,  Subtract 4 from both sides, then add -8x to both sides.

-8x + 40 = 4

36 = 8x

Divide both sides by 8.

[tex]\frac{9}{2}[/tex] (or 4.5) = x

Now, plug this in for x in the second equation to solve for y.

3 × 4.5 + y = 10

13.5 + y = 10

Subtract 13.5 from both sides.

y = -3.5

Answers

The length of the rectangle is 3l/4, and the breadth of the rectangle is s = 3l/4

Let's call the original breadth of the rectangle "b" and the original length of the rectangle "l". From the information given, we know that:

4b = 3l

We also know that when the breadth is increased by 1m and the length is reduced by 1m, the rectangle becomes a square. Therefore, the new breadth and new length are equal. Let's call the new breadth and length "s".

s = b + 1 = l - 1

We can substitute the first equation into the second equation to get:

s = b + 1 = (3l/4) - 1

Now we can solve for s:

s = b + 1m = (3l/4) - 1m

s = (3l/4) - 1m + 1m = (3l/4) = l - 1m

Now we can substitute this back into the first equation:

4b = 3(l - 1m)

We can now solve for b:

4b = 3l - 3m

b = (3l/4) - (3m/4)

Therefore, the original breadth of the rectangle was (3l/4) - (3m/4) and the original length was 3l/4.

We can find the value of length and breadth by substituting the value of s in the first equation

4s = 3l

s = 3l/4

So, the length of the rectangle is 3l/4, and the breadth of the rectangle is s = 3l/4
