if the line my + x = cm passes through the point of intersection of the lines x–23 = –4y and 7x = 3y +6 and parallel to the line 5x – 4y = 6‚ then find the value of m and c |
Answer» Answer:m = 5 / 4 c = 37 / 5 Step-by-step explanation:Given : A line line passes through intersection of the two lines. We have given two lines equation. We know it line passes through point it value of x and y satisfy every points. We have : x - 23 = - 4 y Multiply it by 3 - 12 y = 3 x - 69 ... ( i ) 7 x = 3 y + 6 Multiply it by 4 12 y + 24 = 28 x - 12 y = 24 - 28 x .... ( ii ) From ( i ) and ( ii ) 3 x - 69 = 24 - 28 x 31 x = 93 x = 3 Putting x = 3 : x - 23 = - 4 y - 4 y = - 20 y = 5 Now we have intersection point ( 3 , 5 ) Also the line m y + x = c m passes so it will satisfy value x and y. 5 m + 3 = c m .... ( iii ) Also given : 5 x - 4 y = 6 is PASSING parallel to m y + x = c Therefore , slope their will be equal : Slope of the line 5 x - 4 y = 6 Comparing with standard equation : A x + B y + C = 0 Slope of line m = - A / B So Slope of the line 5 x - 4 y - 6 = 0 m = 5 / 4 Putting value of m in : 5 m + 3 = c m 25 / 4 + 3 = 5 / 4 c 25 + 12 / 4 = 5 / 4 c 37 = 5 c c = 37 / 5 Hence the value of m is 5 / 4 and c is 37 / 5 . |

|
Answer» Step-by-step EXPLANATION: To prove -----> tan²θ + Cot²θ + 2 = Sec²θ Cosec²θ Proof-----> LHS= tan²θ + Cot²θ + 2 Multiplying and dividing by tanθ in third TERM , we GET, = ( tanθ )² + ( Cotθ )² + 2 tanθ ( 1 / tanθ ) We KNOW that , Cotθ = 1 / tanθ , applying it we get, = ( tanθ )² + ( Cotθ )² + 2 tanθ Cotθ We know that, a² + b² + 2ab = ( a + b )² , applying it , we get, = ( tanθ + Cotθ )² We know that, tanθ = Sinθ / Cosθ , Cotθ = Cosθ / Sinθ , applying it we get, = { ( Sinθ / Cosθ ) + ( Cosθ / Sinθ ) }² = { ( Sin²θ + Cos²θ ) / Sinθ Cosθ }² We know that, Sin²θ + Cos²θ = 1 , applying it we get, = ( 1 / Sinθ Cosθ )² = 1 / Sin²θ Cos²θ = ( 1 / Sin²θ ) ( 1 / Cos²θ ) We know that , 1 / Sinθ = Cosecθ , 1 / Cosθ = Secθ , applying it , we get, = Cosec²θ Sec²θ = RHS |

Symmetry chapter formula |
|
Answer» Answer: The WORD symmetry implies balancing. It can be applied to many contexts and situations. Symmetry is found in geometry when a figure can be divided into two equal halves which are exact reflections of each other. In geometrical mathematics, symmetry is a very interesting concept. It is also reflecting in real life. This article will show this popular concept. Let us start with learning symmetry formula. Symmetry Definition Symmetry comes from the Greek word meaning ‘to measure together’. It is widely used in the study of geometry. Thus, it means that one shape becomes exactly like another shape when we move it in some way such as turn, flip or slide. For two objects to be symmetrical, it is necessary that they must be the same size and shape. There can also be symmetry in one object, as our face. If you draw a line of symmetry down the center of our face, we can see that the LEFT side is a mirror image of the right side. But, not all objects have symmetry and such objects are called asymmetric. Types There are several types of symmetry which are as follows: Reflective or line symmetry, Reflective or line symmetry,Rotational symmetry, Reflective or line symmetry,Rotational symmetry,Point symmetry, Reflective or line symmetry,Rotational symmetry,Point symmetry,Translational symmetry, Among these types, two are considered the most important and are explained in detail in the following articles- Reflection Symmetry What if we took a picture of ourselves, as a passport-type photograph, and drew a line straight down the MIDDLE of the face. We can notice that it seem as if one side of our face was a reflection of the other. Ideally, our passport photo is just one example of reflection symmetry. It is also known as a bilateral, line, or mirror symmetry. The line we drew to divide our face is called the line of symmetry. Rotational Symmetry The recycling icon in our computer is a very common symbol and the image itself is suggestive of its meaning. The arrows of the image appear to be moving in a circular manner and therefore suggesting the circular concept of recycling. So, if we rotate this image by 120 degrees, then it would look the same at all three stops. This type of symmetry is called rotational symmetry. Many shapes have rotational symmetry, like rectangles, squares, circles, and all regular polygons. Some Important Terms Some Important TermsLine of Symmetry It is a line about which the figure can be folded so that the two parts of the figure may coincide. For regular polygons, there are many lines of symmetry. The number of lines of symmetry for some common polygons is as given below. Type of Regular Polygon Number of Lines of Symmetry Type of Regular Polygon Number of Lines of SymmetryEquilateral Triangle 3 Type of Regular Polygon Number of Lines of SymmetryEquilateral Triangle 3Square 4 Type of Regular Polygon Number of Lines of SymmetryEquilateral Triangle 3Square 4Regular Pentagon 5 Type of Regular Polygon Number of Lines of SymmetryEquilateral Triangle 3Square 4Regular Pentagon 5Regular Hexagon 6 Centre and Angle of Rotation The center of rotation is a fixed point from which an object is rotated. Also, the angle of rotation is the angle by which an object rotates. This rotation can be either clockwise or anticlockwise and angle can be up to 360 degrees. Order of Rotational Symmetry The order of rotational symmetry is the number of times an object will look exactly the same after a COMPLETE turn. Such as the order of symmetry for a square is 4 and for an equilateral triangle, it is 3. Please Mark My Answer As BRAINALIST. |

TUUU cmTRY THESEConvert the following:(1) 50 cm in mm? (ii) 211.7 APPLICATIONS |
|
Answer»
Centimeter Definition: A centimeter (symbol: cm) is a unit of length in the International System of Units (SI), the current form of the metric system. It is defined as 1/100 meters. History/origin: A centimeter is based on the SI unit meter, and as the prefix "centi" indicates, is equal to one hundredth of a meter. Metric prefixes range from factors of 10-18 to 1018 based on a decimal system, with the base (in this CASE the meter) having no prefix and having a factor of 1. Learning some of the more commonly used metric prefixes, such as kilo-, mega-, giga-, tera-, centi-, milli-, micro-, and nano-, can be helpful for quickly navigating metric units. Current use: The centimeter, like the meter, is used in all sorts of applications worldwide (in countries that have undergone metrication) in instances where a smaller denomination of the meter is required. Height is commonly measured in CENTIMETERS outside of countries like the United States. Millimeter Definition: A millimeter (symbol: mm) is a unit of length in the International System of Units (SI). It is defined in terms of the meter, as 1/1000 of a meter, or the distance traveled by light in 1/299 792 458 000 of a second. History/origin: The milli- prefix is one of many metric prefixes. It indicates one THOUSANDTH of the base unit, in this case the meter. The definition of the meter has changed over time, the current definition being based on the distance traveled by the speed of light in a given amount of time. The relationship between the meter and the millimeter is constant however. Prior to this definition, the meter was based on the length of a prototype meter bar. In 2019, the meter has been re-defined based on the CHANGES made to the definition of a second.

The average monthly mortgage payment including principal and interest is $982 in the U.S. If the standard deviation is $180 and the mortgage payments are approximately normally distributed. Find the probability that a randomly selected monthly payment is more than $1000 |
|
Answer» Step-by-step EXPLANATION: The Z-score for a NORMAL distribution is given by Z = (x-mu)/sigma x=1000 mu=982 sigma=180 So z-score=(1000-982)/180 z-score=0.1 For 0.1 Z-score, the RESPECTIVE probability from the Z-table is 0.5398 So the required probability is 53.98% |

Kris claims that the two figures must be congruent. Two triangles have angles 100 degrees, 50 degrees, and 30 degrees. Which statement best describes his claim? He is correct because both figures are triangles. He is correct because the measures of the angles are the same in both figures. He is incorrect because the triangles are not oriented the same way. He is incorrect because the lengths of the corresponding sides of the figures are unknown. |
Answer» "He is incorrect because the lengths of the corresponding sides of the FIGURES are unknown."Step-by-step explanation: Kris claims that the TWO figures must be congruent. Two triangles have ANGLES 100 degrees, 50 degrees, and 30 degrees.
