What is the equation of the following graph in vertex form?
Elza [17]
\bf \boxed{y=(x-{{ h}})^2+{{ k}}}\\\\
x=(y-{{ k}})^2+{{ h}}\qquad\qquad  vertex\ ({{ h}},{{ k}})\\\\
-----------------------------\\\\
\textit{vertex is at 4,-4}\implies 
\begin{cases}
h=4\\
k=-4
\end{cases}\implies y=(x-4)^2+(-4)
\\\\\\

Describe all the positive integers that would make [(1/2|4] less than (1/2)7
Zielflug [23.3K]

Answer:

The only positive integers would be anything less than 3. So 1 or 2 would work

Step-by-step explanation:

If something that is already being raised to a power, gets raised to another power, those powers add up. So if it were (\frac{1}{2} ^{2} )^{2}, the exponents would add which would make it (\frac{1}{2}^{4} ).

In the case of your question, if 'n' was 2 it would be to the power of 6 making it less than to the power of. 1 could also work

Suppose you choose a marble from a bag containing 6 red marbles , 2 white marbles and 5 blue marbles you return the first marble
algol [13]

Answer:

30/169

Step-by-step explanation:

We need to know how many marbles in the bag

6 red marbles + 2 white marbles + 5 blue marbles = 13 marbles

P (red) = red / total = 6/13

We then put the marble bad so there are still 13 marbles in the bag

P(blue) = blue /total = 5/13

P (red then blue ) = P(red) *P(blue)

                             = 6/13 * 5/13 = 30/169
