Answer:
7569.36
Step-by-step explanation:
Given that a quantity with an initial value of 7800 decays continuously at a rate of 0.1% per hour. What is the value of the quantity after 1.25 days,
First convert 1.25 days to hours
1.25 × 24 = 30 hours
Using exponential equation
N = No ( 1 - R% )^t
Where N = new value of the quantity
No = initial value
R = rate
t = time
N = 7800 ( 1 - 0.001 )^30
N = 7800 ( 0.999 )^30
N = 7800 × 0.97043
N = 7569.36154
N = 7569.36 to the nearest hundredth.
Therefore, the value of the quantity after 1.25 days is 7569.36
