Focal length of convex length Aim: to investigate how to measure the focal length of a convex lens‚ by using the lens equation: 1/f=1/u+1/v * Independent variables: * Screen * lens * Dependent variables: * distance between the source of light and the lens “V” which is “X” value * distance between lens and the screen “ Y value” * Controlled variables: * ruler * screen size * source of light * Hypothesis: When the lens is displaced further away from the

This week I am to find the equation of a line that is parallel or perpendicular to given lines that pass through specific point. The given equation y=12 x+3 The parallel line must pass through point (-2‚ 1) Parallel lines share the same slope so the slope of the new line will be12. Because I have an ordered pair and the slope‚ I can use point-slope to find the new equation Y-y1=m(x-x1)

OBJECTIVES • To analysis the data of SD Slot Card dimension. • To countermeasure design problem in dimension specification confirmation. • To achieve the tolerance specification by using statistical methods. SCOPE This project was conduct for: • All 12 samples have to take dimension measurement every each SD card slot . • To countermeasure the defect product in order to achieve tolerance by using Statistical Process Control (SPC). • The specification is defined as an Upper Control Limit

The Introduction Abstract Through examining the simple harmonic motion of a mass hanging on a spring‚ three investigations were conducted in the experiment. The experiments include the relation between the period in oscillations and mass‚ and figuring out if the period vs. mass graph should go through the origin and lastly‚ finding the mass needed to create a one second timer. It was investigated by placing a motion detector under a spring that was attached to a clamp which was attached to a retort

Task 2 Use the situation above to complete parts A1 through A5. 1. Find the x-intercept and y-intercept of the given equation algebraically‚ showing all work. Y = -2/3x + 30 x-intercept 0=-2/3x+30 -30=-2/3X (3/2)(-30)=(-2/3x)(3/2) -45=-x 45=x x-intercept: (45‚0) y-intercept y=-2/3(0)+30 y=30 y-intercept: (0‚30) 2. Graph the given equation. • Label each axis of the coordinate plane with descriptive labels. • Label each intercept as “x-intercept” or “y-intercept”

Without knowing something about differential equations and methods of solving them‚ it is difficult to appreciate the history of this important branch of mathematics. Further‚ the development of differential equations is intimately interwoven with the general development of mathematics and cannot be separated from it. Nevertheless‚ to provide some historical perspective‚ we indicate here some of the major trends in the history of the subject‚ and identify the most prominent early contributors. Other

THE LAWS OF RETURN TO SCALE The laws of return to scale explain the behavior of output in response to a proportional and simultaneous change in input. Increase in inputs proportionately and simultaneously is in fact expansion of the scale of production. Statement: “As a firm in the long run increases the quantities of all factors employed‚ other things being equal‚ the output may rise initially at a more rapid rate than the rise of increase in inputs‚ then output may increase in the same proportion

SOCI 111-35D Explain cool hunting. According to the video‚ what is the paradox of cool hunting? Cool hunting is simply how companies hire outside experts to “hunt for whats in” or “find the new/hip style”. They look for the trend setters (the 20%) who are sought out to influence the other 80% of the population. The paradox with that is that once it becomes a public image; they then need to find a new image. Once something new like a trend or theme is brought to sight; it becomes old and you’ll
