Answer:
Step-by-step explanation:
yes....the pair of linear equations has unique solution.....
2x + 3y - 7 = 0 ...... (i)
3x + 2y + 10 = 0 ....... (ii)
on comparing the equation i nd ii with a1x + b1y + c1 = 0
nd a2x + b2y + c2 = 0 reslectively......
a1 = 2 ; b1 = 3 ; c1 = -7
a2 = 3 ; b2 = 2 ; c2 = 10
here....its clear that......
a1 / a2 is not equal to b1 / b2
Therefore the given pair of linear equation have a unique solution........
<span>v = 4/3*pi*r^3
derivating both sides with respect to t
dv/dt = 4*pi*r^2*dr/dt
when d = 1.7, r = 0.85, and dv/dt = 2:
2 = 4*pi*(0.85)^2*dr/dt
thus
dr/dt = 1/(2pi*(0.85)^2)
=1/(2*3.14*0.85^2)
=0.22</span><span />
