Suppose that x and y vary inversely and x =1 when y = 4. Write a function that models the inverse variation. Find the inverse of f(x) = 2(x - 3)^2 - 7, when x is greater than or equal to 3? For a function f(x) defined on (a,b) and for all x_0\in (a,b...
If x and y vary inversely and x=18 when y=8, find x when y=16. View Solution x and y vary inversely. When x=15, then y=6. What will be the value of y when x=9? View Solution Find the constant of variation and the equation of variation in the following. ...
An X-ray is a form of electromagnetic wave, such as radio, infrared, visible, or ultraviolet, which has shorter wavelength than ultraviolet wave, and the energy of each X-ray photon is inversely proportional to the wavelength. Therefore, an X-ray has higher energy compared to other electromag...
X-rays are electromagnetic waves with wavelengths of 0.1 to several 10 nm and energies of 0.1–100 keV (Fig. 1). X-rays with the shorter wavelengths are called hard X-rays and have a high transmission ability, while X-rays with the longer wavelengths are called soft X-rays. Usually, X...
11. Is there an equation or a systematic way to do the calibration and determine a "Meter Constant" value? The general procedure is to use a reference meter to calibrate the meter constant to match the flow rate measured over the range of flow rates that need to be supported by the ...

This equation (1) shows that the temperature rise is proportional to the electrical power and is inversely proportional to the collision diameter s. The equation shows also that the temperature rise depends on the electrical power per diameter. Moreover, temperature rise ΔT is inversely proportiona...
