if x y and z are solution of
((x + xy)/(x + y + 1)) = 2
((2x + xz)/(x + z +2)) = 3
((2 + 2y+ z + yz)/(y + z +3)) = 4
so, the value of
(1/x) + (1/(y + 1)) + (1/(z + 2 )) = ....?
a, b, c are the roots from equation x^3 − 5x^2 − 9x + 10 = 0
If P(x) = Ax^3 + Bx^2 + Cx − 2015 and
P(a) = b + c
P(b) = a + c
P(c) = a + b
What is the value of A + B + C ?
Metal pellets of mass 0.1 kg are fired into an iron plate of large mass m
and specific heat capacity c at a temperature of 15°C . 25% of the kinetic
energy of the pellets is converted thermal energy and the plate temperature
rises to 16°C. The average speed of the pellets before hitting the plate was ?
550÷11=50 And here 5^2 +5^2 +0^2 =50
