A net force of 5.75 * 103 N [180degree ] acts on a mass of 23.0 kg. If, while the force acts, the mass travels through a displacement of 360 m [210 degree ], what work did the net force do on the object? Into what form of energy was this work transferred?

The random variables X and Y have a joint PDF of the form fX,Y(x,y)=c⋅exp{−12(4x2−8x+y2−6y+13)} E[X]= var(X)= E[Y]= var(Y)=

An artist paints t shirts. It takes 15 mins to set up and 40 mins to clean up. Once it is set up it takes the artist 12 mins to paint the shirt. What would an equation be for how many shirts he makes in 127 mins?

Suppose f and g are continuous functions such that f(3) = 4 and limx→3[f(x)g(x)+7g(x)] = 12. Find g(3).

Explain why the following functions are continuous on the given open intervals: (a) f(x) = 3x 2 + 7 x − 4 on (4,∞).

Take n=1 6^1+4 =>10 which is divisible by 5. 6^n+4 is divisible by 5 for all nEN. Take n= n+1 6^n+1 +4 => 6^n*6 +4 => 6[6^n +4] as 6^n+4 is divisible by 5 for all nEN 6*[multiples of 5] also divisible by 5 Hence 6^n+4 is divisible by 5 for all nEN.

Take 1st equation 2m-3p-n=0 Take 2nd equation 2m-5p-n=14 ---------- now exchnage signs of the 2nd equation and do adition with changed signs. 2m -3p -n= 0 2m -5p -n= 14 (-) (+) (+) (-) -------------------- 2p = -14 p = -7 value of p is -7
