The following equation represents the number of fish in a pond, f(x), after x number of weeks. f(x) = 500 (1.2)^x. how many fish are in the zoo at the beginning of the study (week 0)? (4.2)
a. 500
b. 120
c. 20
d. not enough information

500

Step-by-step explanation:

They are asking what happens at x=0. Plug it in and you should see you get 500(1.2)^0=500(1)=500.

500 is the initial amount of fish

46.2+112.3

step-by-step explanation:

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
