A swim meet has 13 contestants signed up for the 100-meter butterfly event. The first heat has 6 swimmers. How many different wa

Answer:

6 swimmers in the first heat can be arranged in 1716 different ways.

Step-by-step explanation:

A swim meet has 13 contestants signed up. To calculate the arrangement of first 6 swimmers in first heat we will use combinations because order doesn't matter.

So to select 6 swimmers out of 13 contestants number of different ways

= $^{13}C_{6}$

= $\frac{13!}{(6!)(13-6)!}$

= $\frac{13\times 12\times 11\times 10\times 9\times 8\times 7!}{6!\times 7!}$

= $\frac{13\times 12\times 11\times 10\times 9\times 8}{6\times 5\times 4\times 3\times 2\times 1}$

= $\frac{1235520}{720}$

= 1716

Therefore, 6 swimmers in the first heat can be arranged in 1716 different ways.

Y= - x^2 + 4x + 6 in vertex form

serg [7]

<h3>HI THERE!</h3>

$\rm \color{lime}(2,10)$

step-by-step explanation:

$\rm \color{lime}y = - {x}^{2} + 4x + 6$

identify the coefficients

<h2 /><h2> $\rm \color{lime}a = - 1,b = 4$ </h2>

substitute the coefficient into the expression
find the x-coordinate of the vertex by substituting a = - 1 and b=4 
 $\tt \tiny \: x = - \frac{b}{29}$

 $\rm \color{lime}x = - \frac{4}{2x( - 1)}$ 

solve the equation for X
find the y-coordinate of the vertex by evaluating the function for x = 2

 $\rm \color{lime}y = - {x}^{2} + 4x + 6,x = 2$ 

calculate the function value for x = 2

$\rm \color{lime}y = 10$

since the value of the function is 10 for x = 2 the vertex of the graph of the quadratic function is a (2,10)

 $= \rm \color{hotpink} (2,10)$ 

hope it helps
