Answer:
A
Step-by-step explanation:
A recursive formula allows the term in a sequence to be obtained from the previous term.
To find any term in the sequence multiply the previous term by the common ratio r
r = - 6 ÷ 2 = 18 ÷ - 6 = - 3
Thus the 9 th term can be found using
f(9) = f(8) × - 3 = - 3f(8) → A
Find 2% of 7 billion.
7,000,000,000 x .02 = 140,000,000
About 140 million people have red hair.
Answer:

Step-by-step explanation:
This problem can be modeled by a linear function, where we have two points (37°C, 200) and (32°C, 150).
Notice that the temperature is the independent variable, because the heartbeat of the cat won't change the temperature, it works in the opposite way.
First, let's find the constant ratio of change.

This means the hearbeat of the car changes 10 pulses per minute each 1 celsius degree.
Now, we use the point slope formula to find the equation

Theerefore, the function that represents this situation is

Where
represents temperature and
represents hearbeats.
