Answer: 18.5
Step-by-step explanation: 1184/64= 18.5
The <em><u>correct answer</u></em> is:
B) an exponential function with a growth factor of 2
Explanation:
An exponential function is one of the form f(x) = aˣ, where a is some constant. Exponential graphs are smooth curves.
This graph is a smooth curve. Looking at the points plotted, we have:
(0, 1); (1, 2); (2, 4); (3, 8)
The growth factor is the number we multiply each value by to find the next one. From 1 to 2, we would multiply by 2; from 2 to 4, multiply by 2; from 4 to 8, multiply by 2. This makes the growth factor 2.
No, They will need 131.94 more dollars.
The exponential growth formula can help us find how much is to be deposited each month and then adding them together for the 5 months after the initial deposit will give us the amount saved.
a is the initial value (120)
r is the rate of growth (0.25)
x is time [0,1,2,3,4,5)
