Answer:
(a) 5440.42 g
Step-by-step explanation:
The amount remaining (Q) is given in terms of the initial amount (Q₀) by the exponential decay formula ...
Q = Q₀(1/2)^(t/330) . . . . . where t is in days
__
The amount after 540 days is ...
1750 g = Q₀(1/2)^(540/330) = 0.321666Q₀
Q₀ = (1750 g)/(0.321666) ≈ 5440.42 g
The initial quantity was about 5440.42 grams.
Answer:
y=-2
Step-by-step explanation:
2x-y=12
-
x+3y=-1
2)
2x-y=12
-
2x+6y=-2
3)
-7y=14
y=-2
<span>(3/4)*(5z+16)
((3/4) * 5z + </span>(3/4) * 16<span>)
3.75z + 12
is that the answer you are looking for?
if you want me to solve for "z" I can but you are asking for an expression not to solve...</span>
