Answer: 0.79
Step-by-step explanation:
Given: The cost price of car = $19,000
The rate of depreciation = 21 % = 0.02
The exponential decay equation (depreciation) is given by :-
, where A is the initial amount and b is the decay factor for x years such that
, where r is the rate of decay.
If we substitute the value of r , we get
The decay factor =
Answer:
Step-by-step explanation:
Step 1: Write out equation
a(t + z) = 45z + 67
Step 2: Distribute <em>a</em>
at + az = 45z + 67
Step 3: Subtract 67 on both sides
at + az - 67 = 45z
Step 4: Subtract az on both sides
at - 67 = 45z + az
Step 5: Factor out <em>z</em>
at - 67 = z(45 + a)
Step 6: Divide both sides by 45 + <em>a</em>
