Answer:

(C) 560

Step-by-step explanation:

Total students = 16

Number of students to send = 3

Since the position is not important,

Number of combination

= (16 x 15 x 14) / (1 x 2 x 3)

= 3360/6

= 560

Hey can you please help me posted picture of question
Dmitry_Shevchenko [17]
Answer:
The solutions are: 
\frac{3 + i}{2} and \frac{3 - i}{2}

Explanation:
The general form of the quadratic equation is:
ax² + bx + c = 0
The given equation is:
2x² - 6x + 5 = 0

By comparison:
a = 2
b = -6
c = 5

Now, to get the solutions of the equation, we will have to use the quadratic formula shown in the attached image.

By substituting in the formula, we would find that:
either x = \frac{6 +  \sqrt{(-6)^2 - 4(2)(5)} }{2(2)}  =  \frac{3 + i}{2}

or x = \frac{6 - \sqrt{(-6)^2 - 4(2)(5)} }{2(2)} = \frac{3 - i}{2}

Hope this helps :)

A bacteria culture has 2,000 bacteria. The number of bacteria increases by 5% each hour. How many bacteria are there after 12 ho
ivann1987 [24]
Suppose the number of bacteria are increasing exponentially, We can model the number of bacteria at a given time t, using the formula:
f(t)=ae(tk)
where, k=constant of proportionally and a=initial number;
thus;
f(t)=2000e(0.005t)
Therefore the population after 12 hours will be:
f(12)=2000e^(0.005*12)
f(12)=2,123.67=2,123 bacteria
