Answer:
(d) Inverse of f. Domain: 6, 9, 3. Range: 8, 10, 12. 6 goes to 8; 9 goes to 10; 3 goes to 12.
Step-by-step explanation:
Apparently function f is defined by the ordered pairs (8, 6), (10, 9), (12, 3).
The inverse function will be defined by the ordered pairs with the input and output reversed:
(6, 8), (10, 9), (3, 12)
This seems to be described by the last answer choice.
It’s 1/50 because 2% is 2/100 which can be simplified to 1/50
Answer:

Step-by-step explanation:
The formula for simple interest is

where <em>p</em> is the principal, <em>r </em>is the rate, and <em>t</em> is the time.
The principal, or initial amount is $800 and the time is 5 years The interest rate is 2.5%, but we must convert to a decimal.
Divide by 100 or move the decimal place two spots to the left.
- 2.5/100=0.025 or 2.5 ⇒ 0.25 ⇒ 0.025
Substitute the known values into the formula.


Multiply.
