Find the exponential function that satisfies the given conditions:

Initial value = 62, decreasing at a rate of 0.47% per week.

A. \( f(t) = 62 \cdot 0.9953^t \)
B. \( f(t) = 62 \cdot 1.47^t \)
C. \( f(t) = 62 \cdot 1.0047^t \)
D. \( f(t) = 0.47 \cdot 0.38^t \)

Answer :

Answer:

Option first is the correct answer

Step-by-step explanation:

Equation for the exponential function is given by

[tex]A= P(1-r)^t[/tex]

where A is amount after t time

P = initial amount

r = rate of interest

If it is decreasing by rate of r%

Here in the question initial value is given to be 62 therefore P = 62

and rate of decreasing is 0.47% which can be written as 0.0047 in decimal form

[tex]f(t) = 62(1-0.0047)^t[/tex]

f(t) = 62[tex](0.9953)^t[/tex]

Is the exponential function that satisfies the condition

therefore option first is the correct answer,

Answer:

f(t) = 62 ⋅ 0.9953t


Step-by-step explanation:

The function decreases at a rate of 0.47%

That will mean, the initial value decreases by 0.47?

100% - 0.47% = 99.53%

The next value will be 99.53% of the initial value.

∴ 99.53% × 62 = 0.9953 × 62.

After a time t, the value will be:

0.9953t × 62

∴ Answer = 62 × 0.9953
