True or false. If true or false state your reason. 2 lanes are subspaces of R2 because: if we have y=mx and (t, mt) 1. They are closed under addition: (t, mt)+(s, ms)=(t+s, m*(t+s)) 2. They are closed under scalar multiplication: r*(t, mt)=(rt, r*(mt)) 3. Zero vector because they pass through the center of grid coordinates. These 2 lanes are isomorphic because for each x there is y1 and y2 (one-to-one). Similarly, each plane in R3 passing through origin is a subspace and has equation ax+by+cz=0. Both planes isomorphic because they also have one-to-one correspondence between points on the plane Thank you. Solution This is TRUE.....zero vector acts as the identity element....so a plane to be subspaces it need to pass through origin.....in case of y = mx the plane is passing through origin and hence it forms subspaces..... .

Lesson 14 b - parametric-1
Parametric equations describe curves using two functions, one for the x-coordinates and one for the y-coordinates, rather than a single function relating x and y. They allow curves to be described that cannot be expressed as a single-valued function. The parameter, often representing time or an angle, does not appear in the final graph but is used to generate the coordinates.

coordinate Geometry straight line
René Descartes introduced a coordinate system that represented geometric figures using algebra. This allowed geometry and algebra to be linked by applying the methods of one field to problems in the other. The document then discusses several ways that geometry is used in daily life and provides formulas to calculate distances and areas using coordinate systems. It also defines key geometric concepts like slope, parallel and perpendicular lines, and the angle between two lines in terms of their slopes. Overall, the document outlines Descartes' contributions to representing geometry algebraically and defines important geometric relationships using coordinates.
Linear functions
A linear function is an equation of the form y = mx + b, where m is the slope and b is the y-intercept. The slope is defined as the ratio of the rise over the run between any two points on the line. Lines with the same slope are parallel, while lines with slopes that are negative reciprocals of each other are perpendicular. There are also horizontal and vertical lines, where horizontal lines have a slope of 0 and vertical lines have an undefined slope. The point-slope form of a line is used to find the equation of a line given a point and the slope.

The document proposes a new method called Spectral Regression Discriminant Analysis (SRDA) to address the computational challenges of Linear Discriminant Analysis (LDA) on large, high-dimensional datasets. SRDA combines spectral graph analysis and regression to reduce the time complexity of LDA from quadratic to linear. It works by using the eigenvectors of the within-class scatter matrix to define a regression problem, the solution of which provides the projection vectors that maximize class separability. Experiments on four datasets show SRDA has comparable classification accuracy to LDA but can scale to much larger problems.
LU-17 Closest pair and convex hull using divide and conquer.pptx
The Closest Pair Problem can be solved using a divide and conquer algorithm. The algorithm works as follows:
1. Sort the points by x-coordinate and then y-coordinate.
2. Divide the points into two subsets by a median splitting line.
3. Recursively find the closest pairs in the subsets. Combine the results, checking for closer pairs that cross the splitting line.
The algorithm runs in O(n log n) time, making it efficient for solving the Closest Pair Problem.

Principal Component Analysis
Principal component analysis (PCA) is a technique used to reduce the dimensionality of data by transforming correlated variables into a smaller number of uncorrelated variables called principal components. The first principal component accounts for as much of the variability in the data as possible, and each succeeding component accounts for as much of the remaining variability as possible. PCA involves computing the covariance matrix of the data and then determining the eigenvectors with the highest eigenvalues, which become the principal components.

Image compression
This document discusses singular value decomposition (SVD) and its applications in image processing. SVD decomposes a matrix A into three matrices - left singular vectors U, singular values Σ, and right singular vectors V. This reveals the dominant information encoded in the matrix and allows the matrix to be approximated by its first few terms. SVD can be used for image compression, representing an image with far fewer values by keeping only the first few terms. Other applications of SVD include computer tomography, magnetic resonance imaging, seismology, and image deblurring.

Solution
Quantitative methods place greatest reliance on representing developments numerically. Numerical data, of many types, are useful in thinking about longer-term developments, and to a certain extent they can be useful ways of presenting Foresight results, too.
As in in econometrics, quantitative methods implicitly or explicitly use simple models of some sort. For example, time series extrapolations of trends imply a model in that use time as the \"independent variable\"

ty ty +x +X SolutionLet- mass of each rod - m - M length of each rod -.docx
ty ty +x +X
Solution
Let, mass of each rod , m = M
length of each rod , L = 7.5 m
Case(a): ( with all four rods )
Total mass, m1 = 4 M
X-coordinate of center of mass , X1 =0
Y-coordinate of center of mass , Y1 =0
Case (b) : ( for the removed rod )
mass, m2 = M
X-coordinate of center of mass , X2 =L / 2 = 7.5 /2 = 3.75 m
Y-coordinate of center of mass , Y2 =0
Center of mass of the remaining part:
X-coordinate of center of mass , Xcm = (m1 X1 - m2 X2 ) / ( m1- m2 )= ( 4 M * 0 - M * 4.0 ) / ( 4 M - M ) = -1.33 m
Y-coordinate of center of mass , Ycm = (m1 Y1 - m2 Y2 ) / ( m1- m2 )= ( 4 M * 0 - M * 0 ) / ( 4 M - M ) = 0 m

true or false The Doppler effect is a change in frequency due to the r.docx
true or false
The Doppler effect is a change in frequency due to the relative motion of a source of sound.
27. The amplitude of the wave is the time it takes it to pass a point.
28. When light passes through a lens it bends due to the property called refraction.
29. A magnifying glass when used to enlarge letters on a page is producing a virtual image.
30. The normal hearing range is between 20 hz and 80,000 hz
Solution
1) doppelr effect is true
2) amplitude is the displacement of the particle from the mean position
false
3) refraction means bending nature of light it is true
4) true
magnifying lens is used to see the smaller objects to larger objects
5) normal hearing range is 20 to 20000 Hz
false

Solution
6. As the refractive index contiuously changes the direction of the light ray also changes contiuously, since when light ray enters into denser medium its direction will change.
7.Since air is optically rarer than water, the ray of light bends away from the normal at the point of incidence when moving from water to air while it bends towards the normal while moving from air to water. The normal at any point of a spherical bubble will pass through the center of the bubble.
It is clearly visible that the air bag acts as a DIVERGING LENS (concave lens) in water.

True or False 1- One good feature about memory-memory instruction set.docx
True or False
1. One good feature about memory-memory instruction set architecture is the low memory traffic.
2. Data/internal forwarding means that data will be stalled in the pipeline before it is written into the register file.
3. When stalling occurs in a pipeline, it will stall all instructions in front of it as well as behind it.
4. One good thing about registers is that there are an unlimited amount to use.
5. In pipelining a structural hazard occurs when at least two instructions need access to the same hardware resource.
Solution
1.TRUE

True or false- If true or false state your reason- 2 lanes are subspa.docx
- 1. True or false. If true or false state your reason. 2 lanes are subspaces of R2 because: if we have y=mx and (t, mt) 1. They are closed under addition: (t, mt)+(s, ms)=(t+s, m*(t+s)) 2. They are closed under scalar multiplication: r*(t, mt)=(rt, r*(mt)) 3. Zero vector because they pass through the center of grid coordinates. These 2 lanes are isomorphic because for each x there is y1 and y2 (one-to-one). Similarly, each plane in R3 passing through origin is a subspace and has equation ax+by+cz=0. Both planes isomorphic because they also have one-to-one correspondence between points on the plane Thank you. Solution This is TRUE.....zero vector acts as the identity element....so a plane to be subspaces it need to pass through origin.....in case of y = mx the plane is passing through origin and hence it forms subspaces.....
