જો (1 + x)^(n) ના વિસ્તરણમાં સતત ત્રણ પદોના ગુણાંક 165,330 અને 46 છે...

If the coefficients of three consecutive terms in the expansion of (1 + x)^(n) are 165,330 and 462 respectively , the value of n is is

If three consecutive coefficients in the expansion of (1+x)^n be 165,330 and 462, find n and the position of the coefficeint.

Let a,b,cR .If f(x)=ax^(2)+bx+c is such that a+b+c=3 and f(x+y)=f(x)+f(y)+xy,AA x,yR, then sum_(n=1)^(10)f(n) is equal to 190(2)255(3)330(4) 165 165

The sum of deviations of a set of values x_(1), x_(2), x_(3), …… x_(n) measured from 50 is -10 and the sum of deviations of the values from 46 is 70. Find the value of n and the mean.

A 4.10 kg block is pushed along a floor by a constant applied force that is horizontal and has a magnitude of 50.0 N. Figure 6-46 gives the block's speed v versus time t as the block moves 0.5 1.0 along an x axis on the floor. The scale of the figure's vertical axis is set by v_(s) = 5.0 m/s. What is the coefficient of kinetic friction between the block and the floor?
