Which equation represents exponential growth? a. f(x)=2(3)^x b. f(x)=3(0.11)^x c. f(x)=2(1/2)^x d. f(x)=5(1/6^x)

Growth means a base for exponentiation bigger than 1  (in absolute value), otherwise it's decay.

Only the first choice has a base biggerthan 1.  The last choice is equivalent to so has a base less than 1.

A

Note how answer A has the form  (constant)(constant greater than 1)^exponent.  This is how you recognize expo growth.  The other 3 answer choices are disqualified because their bases {0.11, 1/2, 1/6} are fractions between 0 and 1.

The correct answer is A.

the answer is 14ft

step-by-step explanation:

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
