Answer:
The Time period required for decay of Iodine-125 to half of its value is 60 days .
Step-by-step explanation:
Given as :
The initial quantity of iodine-125 = 0.4 gram
The rate of decay = 1.15 %
Let The time period for decay = x day
The finial quantity after decay = half of initial quantity
I.e The finial quantity after decay = 0.2 gram
Now ,
The final quantity after decay = initial quantity ×
Or, 0.2 gm = 0.4 gm ×
or, =
Or, 0.5 =
Or, = 0.9885
Taking log both side
log ( ) = Log 0.9885
or, × log 0.5 = - 0.0050233
or, × ( - 0.301029 ) = - 0.0050233
or, x =
∴ x = 59.92 ≈ 60 days
Hence The Time period required for decay of Iodine-125 to half of its value is 60 days . Answer
X * .64 = 1200
x * .64/.64 = 1200/.64
x = 1875

1. <u>Plug in</u> " -2 " into f
f(-2) = 3 (-2) - 1
f(-2) = -6 - 1
f(-2) = -7
2. <u>Plug in</u> "5" into g
g(5) = -(5) + 6
g(5) = -5 + 6 = 1
3. <u>Add</u> what you got when you solved for <u>f(-2) and g(5) together</u>
f(-2) + g(5) = ?
f(-2) + g(5) = -7 + 1
f(-2) + g(5) = -6
