Answer: 680
Step-by-step explanation:
When order doesn't matter,then the number of combinations of choosing r things out of n = 
Given: Total participants = 17
From these, a group of 3 participants is to be tested under a special condition.
Number of groups of 3 participants chosen = 

Hence, there are 680 groups of 3 participants can be chosen,.
The answer would be -3.333333
Step 1: (1÷3)= 0.333333
Step 2: 3+0.333333= 3.333333
Step 3: Finally you would bring the negative sign down and the answer would be -3.333333! I hope this helps :)
Answer:
option B : 
Step-by-step explanation:
(a) 
For exponential function , there is no vertical asymptotes
General form of exponential function is


In the given f(x) the value of k =0
So horizontal asymptote is y=0
(b) lets check with option

To find vertical asymptote we set the argument of log =0 and solve for x
Argument of log is x-39
x-39=0 so x=39
Hence vertical asymptote at x=39
The quadratic formula, i need a pic
