Answer: B
Step-by-step explanation:
From the given table
When x changes from 1 to 2 , value of y changes from 6 to 4
The multiplicative rate of change=
Similarly we can check
When x changes from 2 to 3 , value of y changes from 4 to
The multiplicative rate of change=
When x changes from 3 to 4 , value of y changes from to
The multiplicative rate of change=
Therefore, the multiplicative rate of exponential function =
Answer:
Yes it is.
Step-by-step explanation:
Just multiply everything by 2.
Answer:
The man covers 200 ft in 40 seconds.
Step-by-step explanation:
A person is moving on the sidewalk from one end to the other end.
He walks 40 feet in 8 seconds.
Therefore his speed =
=
= 5 ft/
He covers the sidewalk distance at a rate of 5 feet every second.
To calculate the time taken to cover 200 ft,
time =
time =
<u>time = 40 seconds</u>
Hence the man covers 200 ft in 40 seconds.
