What is the sum of an interior angle of a 18 -side polygon?
The sum of the interior angles are (18-2)*180 = 2880 degrees
What is the sum of the measures of the interior angles of an 18-gon?
(18-2)*180 = 16*180 = 2880 degrees.
Find the sum of the measures of the interior angles of a convex 18-gon?
Use the formula (n - 2)180 to find the sum of the measures of the interior angles of any regular convex polygon, where n is the number of sides. (n - 2)180 = (18 - 2)180 = (16)180 = 2880
What are the two complementary angles in the ratio 3 to 2?
Complementary angles sum to 90° In that ratio of 3:2, there are 3+2 = 5 parts 90° ÷ 5 parts = 18° per part The angles are: 3 × 18° = 54° 2 × 18° = 36°
What is the length of DE where EF is a median of trapezoid ABCD the length of AB is 12 and the length of CD is 18?
The median of a trapezoid is one half of the sum of the two sides. So EF is 1/2 (12+18) = 1/2 (30) = 15.
Formula to calculate magnitude of the resultant vector?
Magnitude of the resultant vector = Square root of[ (sum of x-components of all component vectors)2 plus(sum of y-components of all component vectors)2plus (sum of z-components of all component vectors)2 ]
Is a scalar a component of a vector?
Answer: A vector is always the product of 2 scalars
How do you find sum of both vector?
Two methods can be used for vector addition. (1) Graphically. Place the vectors head-to-tail, without changing their direction or size. (2) Analytically, that is, mathematically. Add the x-component and the y-component separately. The z-component too, if the vectors are in three dimensions.
What is the energy of motion or the energy an object has as a result of its motion?
Kinetic Energy, which is: KE = 1/2mv^2 or the kinetic energy is equal to one half the sum of the mass and the square of the velocity Answer2: Energy is a quaternion quantity with a scalar/potential and a vector component. The vector component is mcV. Physics does not recognize vector energy. Kinetic energy is rightfully the vector energy mcV, not a scalar energy, 1/2 mv^2.

What is the relationship between the infinity norm and the 2 norm in a vector space, and how can one be less than the other?
In a vector space, the infinity norm and the 2 norm are different ways to measure the size of a vector. The infinity norm is the maximum absolute value of any component in the vector, while the 2 norm is the square root of the sum of the squares of all the components. The infinity norm can be less than the 2 norm when the vector has a few very large components that dominate the sum of squares in the 2 norm calculation.
In 2 dimensional kinematics can the x component of a vector be great than the vector itself?
No.
What is the magnitude of vector -2 0?
A vector, starting at the origin and going to point (-2,0):Since there is no y-component, the magnitude is the absolute value of the x componentmagnitude = 2magnitude of a vector = sqrt( X2 + Y2) = sqrt ((-2)2 + 02) = sqrt(4) = 2where X & Y are the x-component & y-component of the vector.
How resolution of vector is used in applying the component methods in adding vectors?
The related question has a nice detail of this. Each vector is resolved into component vectors. For 2-dimensions, it is an x-component and a y-component. Then the respective components are added. These added components make up the resultant vector.
Can the magnitude of a vector be less than magnitudes both of components?
The magnitude of the sum of any two vectors can be anywhere between zero and the sum of their two magnitudes, depending on their magnitudes and the angle between them. When you say "components", you're simply describing a sum of two vectors that happen to be perpendicular to each other. In that case, the magnitude of their sum is Square root of [ (magnitude of one component)2 + (magnitude of the other component)2 ] It looks to me like that can't be less than the the magnitude of the greater component.
What is the sum of 2 or more vectors called?
The sum of 2 or more vectors is called the resultant vector. It is the single vector that represents the combined effect of all the individual vectors added together.
It is possible for a vector to be zero if a component of the vector is not zero?
No. The value of a vector is determined by the square root of the sum of its components squared. Value= Sqrt(x^2 + y^2 + z^2). The components of real vectors are real numbers and the square of a real number is a positive number. The sum of a positive and zeros is not zero but a positive. Vectors were created by William Rowan Hamilton in 1843 when he created Quaternions. Quaternions consist of a real number and three vector numbers. The vectors are designated by i, j, k where i^2=j^2=k^2=ijk= -1. The square of a vector is a negative one . This used to be called an imaginary number. The components of vectors are real numbers, like v=2i + 3j -5k, the value of v = sqrt(4 + 9 + 25)=sqrt(38). Complex numbers are a subset of quaternions involving one vector "i".
