Oliver withdraws an amount of $285.10 from his saving account
His saving account earns 1.8% annually
The interest Oliver could have earned in five months:
Monthly interest = Annual interest ÷ 12
Monthly interest = 1.8% ÷ 12
Monthly interest = 0.018 ÷ 12 = 3/2000
After five months = Principle × (1 + interest)ⁿ
After five months = 285.10 × (1 + 0.018)⁵
After five months = 311.70
Interest earned = 311.70 - 285.10 = $26.60
The answer is 1/3 is the answer.

Answer:
d=10
Step-by-step explanation: step 1: 2/5d-1 = 3/5d-3 add 3 to both sides
+3 +3
step 2: 2/5d+2 = 3/5d subtract 2/5d to both sides
-2/5d -2/5d
step 3: 2 = 1/5d multiply 5/1 to both sides
* 5/1 = *5/1
10 = d
Answer:
(0, inf)
Step-by-step explanation:
The average rate of change of a function is related to it's first derivative. When the first derivative is positive, the average rate of change is positive, which means that the function is crescent.
Now, when the first derivative is negative, the average rate of change will be negative too, and the function is going to be decrescent.
In your function.
We have: f'(x) = 2x
2x > 0 when x > 0. So when x > 0 the average rate of change of your function is positive, and it's values increases as the time increases. When x < 0, the average rate of change is negative, so, as the time increases, the values of f decrease.
You can use a graphic tool to plot f and visualize this better.
