Answer:
0.88 s
Step-by-step explanation:
Let x(t) be the volume of nitric acid measured in liters after t minute. Therefore the rate of change in the volume of nitric acid (dx / dt) is:
dx / dt = rate of input of nitric acid - rate of output of nitric acid
rate of input of nitric acid = 6 L/min * 20% nitric acid / 100% solution = 1.2 L/min
rate of output of nitric acid = 8 L/min * x L / 200 L = 0.04x L/min
The percentage of nitric acid in the tank reach 10% at 0.88 s

5×x/5=5×(-20) (reduce and multiply)
X= -100
Answer:
-32
Step-by-step explanation:
=(-2)^5
=-2*-2*-2*-2*-2-2
-2*-2=4
-2*-2=4
-2
4*4=16
16*-2=-32
