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.
Answer:
Irrational
Step-by-step explanation:
Any non-zero rational number multiplied by an irrational number will be irrational. We can rewrite this as (8.57... * 5) / 8, but we have no idea how to make 8.57... * 5 rational, or expressed as the quotient of two integers.
Answer:
80
Step-by-step explanation:
The formula to calculate speed is s=d/t. If the distance is 2,000 m/s and the time is 25 seconds, you plug in the numbers into the formula for speed. 2,000/25=80
The satellite's acceleration (speed) is 80.
(I'm not exactly sure what the unit should be for the answer 80, but...) I hope this helps and have a great day!! :3
Domain is x while Range is Y
