Answer:
61.27 cm
Step-by-step explanation:
(3.14)(11)(0.5) = 17.27
2+2+20+9+11+17.27 = 61.27
We have the equation

Let's complete the square, to do it let's add and subtract 25 on the right side

Now we can have y in function of x

Now we can already identify the vertex because it's in the vertex form:

Where the vertex is

As we can see, h = 5 and k = -2, then the vertex is

Now we can continue and find the focus, the focus is

We have a = 1/20, therefore

The focus is

And the last one, the directrix, it's

Then

Hence the correct answer is: vertex (5, -2); focus (5, 3); directrix y = -7
Answer: x+y
Step-by-step explanation:
Simple.
Since there is nothing splitting, all you need to do is add x and y.
To break it down:
They want to know the hours per week the theater is open. X represents the hours from Sunday to Thursday and Y represents hours from Friday to Sunday therefor all you need to do is add them because they represent Hours.
Let x be the number of weeks for this financial situation. The amount that Katherine will have at the end of x weeks is 140 + 6x. On the other hand, with the spending that she is doing, Abbie will have 462 - 10x after x weeks. Equating the two,
140 + 6x = 462 - 10x
Thus, the answer is letter B.
