Step by Step Answer:
Water : Sucrose : Saline Solution
1 Litre : 600 ml : 150 ml
1 Litre = 1000 ml
1000 ml : 600 ml : 150 ml
100 ml : 60 ml : 15 ml
20 ml : 12 ml : 3 ml
Just plug in 9 for n
a(n) = 7 - 9n
a(9) = 7 - 9(9)
a(9) = 7 - 81
a(9) = -74
so the 9th term is -74
Start by isolating the variable on one side by adding 43w^2 to both sides. The equation will read:
25w^2+5=0
<em>*Subtract 5 from both sides*</em>
25w^2=-5
<em>*Divide both sides by 25*</em>
w^2=-1/5
<em>*Take the square root of both sides*</em>
w=√(-1/5)
The square root of -1 is i. The square root of 5 remains √5
The answer is i/√5.
