Is this a linear function? In that case, f(6) should be simply 13+5 = 18 , but it is not. According to the requirement of a linear function , f(a) +f(b) = f(a+b). According to this requirement, 4x-3 is not a linear function, but an affine function. However, it is equation of a straight line. …

## When finding measurements which comes first length,height,width. {ie} 10by16by24?

This Site Might Help You. RE: when finding measurements which comes first length,height,width. {ie} 10by16by24? Susan Sarandon Measurements length, width, height there is no real standard, they can be in any order. . There is no such rule if which comes first in either length, width or height in any measurements. You may calculate in …

## The diffuser in a jet engine is designed to decrease the kinetic energy of the air coming in the engine..?

No work, no heat transfer – hey, doesn't that mean isentropic?

## Closed system question.how to find the amount of heat transfer?

air is contained in a variable load piston device equipped with a paddle wheel. initially, air is at 500kPa and 27°C. the paddle wheel is now turned by an external electric motor until 50 kJ/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while …

## A catapult launches a test rocket vertically upward from a well?

giving the rocket an initial speed of 79.0 m/s at ground level. The engines then fire, and the rocket accelerates upward at 3.90 m/s2 until it reaches an altitude of 1150 m. At that point its engines fail, and the rocket goes into free fall, with an acceleration of −9.80 m/s2. (You will need to …
