Answer:
4
Step-by-step explanation:
we have
This is a exponential growth function of the form
where
a is the initial value
(1+r) is the base of the exponential function or multiplicative rate of change of the function
r is the rate of change
In this problem we have
therefore
4 is the base of the exponential function or multiplicative rate of change of the function
Answer:
A) 390
Step-by-step explanation:
To now the difference you just have to subtract and will give you 1.68
1^2 is 1+4 times 1 is 5 plus 4 is 9
2^2 is 4+4 times 2 is 12 plus 4 is 16
3^2 is 9+ 4 times 3 is 21 XXXXXXX==> 2 times
Louis is walking at 4 mph. If Louis can walk 2 miles in 30 minutes, she can then walk 4 miles in an hour if you double the amount of time she is walking from 30 to 60, so you would also double the distance. She is walking at 4 miles per hour.
