Second is 8/9

What is the vertex of the function?
egoroff_w [7]
<h2>Explanation:</h2><h2></h2>

Here you haven't provided any function, so I'll assume this one:

f(x)=3x^2-18x+33

This is a quadratic function whose graph represents a parabola. Any parabola has its vertex at the point:

V(x,y) \\ \\ \\ x=-\frac{b}{2a} \\ \\ y=f(-\frac{b}{2a}) \\ \\ \\ where: \\ \\ \\ f(x)=ax^2+bx+c \\ \\ \\ So: \\ \\ a=3 \\ \\ b=-18 \\ \\ c=33

Therefore:

x=-\frac{(-18)}{2(3)}=3 \\ \\ f(3)=3(3)^2-18(3)+33=27-54+33=6

Therefore, the vertex is:

\boxed{V(3,6)}

HELP ME PLEASE
Arada [10]

Answer:

if you toss a dice 30 times, you will roll a two 5 times.

Step-by-step explanation:

If you toss a dice once, the probability of rolling a 2 is 1/6, like you said.

So if you multiply your chances of rolling a 2 by 30, you get;

30.1/6 = 30/6 = 5
