Answer:
The value 1.8 represent the club's total number of members today or the present number of members
Step-by-step explanation:
Given an exponential function;
![y=ab^{x}](https://tex.z-dn.net/?f=y%3Dab%5E%7Bx%7D)
b is the base or the growth factor
a is the initial value, that is the value of y when x = 0
We have been given the exponential function;
![y=1.8(1.02)^{12t}](https://tex.z-dn.net/?f=y%3D1.8%281.02%29%5E%7B12t%7D)
The value 1.8 simply represents the initial value of y. Plug in t = 0 in the equation;
![y=1.8(1.02)^{12(0)}=1.8](https://tex.z-dn.net/?f=y%3D1.8%281.02%29%5E%7B12%280%29%7D%3D1.8)
Therefore, the value 1.8 represent the club's total number of members today or the present number of members.
Noah is right because 75% of 10 is 7.5 and 10% of 30 also equals 7.5
72 because 63 + 9 is basically 9×8
Answer:
7.5
