Answer:
In this problem, if we solve it by linear programming one of the conditions does not satisfy which is - number of B should be produced at least 180 in order to meet backlog. This means for B only we need 180* 4 = 540 lbs of iron where as daily supply is only of 100 lbs.
for this option (3) looks viable i.e. 3A + 4B <= 100
The answer is b I just did it on the test hope it helps
the rate of heart beat is 60 units
Let the distance from the pole be x and the length of the shadow be s. Using the law of similar triangles, we have:
s/6=(x+s)/15
thus
5s=2x+2s
3s=2x
hence
ds/dt=2/3 dx/dt
but
dx/dt=4 ft per second
hence
ds/dt=2/3*4=8/3
