It is AAaaaaaaaaaaaaaaaaaa
4(2) - 5 = 3
4(5) - 5 = 15
4(8) - 5 = 27
4(9) - 5 = 31
so the answers are 3, 15, 27, and 31
Answer:
magnitude of decrease = 120 - 54 = 66$
the percentage = (66/100)×100 = 66%
Answer:
100%
Step-by-step explanation:
An exponential equation with a growth rate can be expressed as:
where r is a positive number, and represents the growth rate.
In this case since the base of the exponent equals 2, that means r=1, since 1+1=2. This means it has a growth rate of 100%, which makes sense, since the base is 2, meaning it doubles or increases by 100% every time x increases by 1.
