how many different ways could 3 girls and 3 boys form a line if the line must alternate boys and girls

mariarad [96]

+ is a girl and = is a boy.

So let's say the line starts with a boy and ends with a girl, there's one way.

= + = + = +

Now, let's reverse it, to where it starts with a girl and ends with a boy.

+ = + = + = +

There are two ways to arrange the line if there must be alternating girls and boys

The graphs below have the same shape. What is the equation of the red graph?

arsen [322]

Answer:

D

Step-by-step explanation:

The red graph is vertically shifted from the blue graph. Let's understand horizontal and vertical shifts.

If we have a graph of $f(x)=x^2$ , then

f(x) + a is a units shifted vertically up
f(x) - a is a units shifted vertically down
f(x-b) is b units shifted horizontally right
f(x+b) is b units shifted horizontally left

Since the red one is vertically shifted 3 units up (compared to blue graph), the equation would be:

$g(x)=f(x)+3\\g(x)=x^2 + 3$

Correct answer is D

please explain/give the new equation from the original equation: f(x) = x2 a shifted 3 units down b shifted 4 units right

$\bf ~~~~~~~~~~~~\textit{function transformations}

f(x)= A( Bx+ C)+ D
\\\\
~~~~y= A( Bx+ C)+ D
\\\\
f(x)= A\sqrt{ Bx+ C}+ D
\\\\
f(x)= A(\mathbb{R})^{ Bx+ C}+ D
\\\\
f(x)= A sin\left( B x+ C \right)+ D
\\\\

\\\\
\bullet \textit{ flips it sideways if } B\textit{ is negative}$

$\bf ~~~~~~\textit{reflection over the y-axis}

~~~~~~if\ \frac{ C}{ B}\textit{ is negative, to the right}\\\\

\bullet \textit{ vertical shift by } D\\
~~~~~~if\ D\textit{ is negative, downwards}\\\\
~~~~~~if\ D\textit{ is positive, upwards}\\\\
\bullet \textit{ period of }\frac{2\pi }{ B}$

and with that template in mind.

3 units down, D = -3

4 units to the right, C = -4

f(x) = (x - 4)² - 3
