It means that there is 0.65 for every D there is.
For example, if it costed $0.65 to pay for each apple, the D would represent the apple and in this case the expression would be 0.65d.
Hope I helped :)

Find f(5) for f(x)=1/9(3)*O A. 27O B. 81O C. 9O D. 3

Vladimir79 [104]

$f(x)=\frac{1}{9}(3^x)$

If the function is asking what if x = 5, then we will substitute the exponent x with 5.

$f(5)=\frac{1}{9}(3^5)$

From the formula above, we will multiply 3 to itself five times (3 x 3 x 3 x 3 x 3) = 243

$f(5)=\frac{1}{9}(243)$

After that, we will multiple 243 to 1/9 or simply divide 243 by 9.

$f(5)=\frac{243}{9}=27$

Therefore, the value of the function if x = 5 is 27. Option A is the answer.
