Hello there!
S = 5r^2 * T
To solve for T, we need to isolate it - or get it on one side of the equation by itself.
To do this, we need to divide both sides by 5r^2.
S/5r^2 = T is now our equation and final solution.
I hope this helps!
Answer:
It will take 60 days for half of the Iodine-125 to decay
Step-by-step explanation:
The amount of iodine-125 after t days is given by the following equation:
In which Q(0) is the initial amount and r is decay rate, as a decimal.
Decay rate of 1.15% per day.
This means that
So
To the nearest day, how long will it take for half of the Iodine-125 to decay?
This is t for which
So
To the nearest day
It will take 60 days for half of the Iodine-125 to decay
To find the tax rate when given the initial price of an object and the final tax value, you use the equation: $350 * X = $22.75 (where X is the sales tax rate). Then solve:
$22.75/$350 = .065
So the rate is 6.5%
A, because of the straight light it goes through the origin
w = 55
y = 55
X = 125
z = 125
