Find the focus. y= -1/12 (x)² - 6

jolli1 [7]

Answer:

$\Large \boxed{\sf\ \ (0,-9) \ \ }$

Step-by-step explanation:

Hello,

We know that when the parabola equation is

$y=a(x-h)^2+k$

the vertex is (h,k) and the focus is

$(h,k+\dfrac{1}{4a})$

Here, the equation is

$y=-\dfrac{1}{12}x^2-6$

$a=-\dfrac{1}{12}\\\\h = 0\\\\k =-6$

So,

$k+\dfrac{1}{4a}=-6-\dfrac{12}{4}=-6-3=-9$

Then, the focus is

$\large \boxed{\sf\ \ (0,-9) \ \ }$

I attached the graph, included the focus so that you can see it :-)

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

Noemi wants to divide 2x^2−x+4 by x−5 using synthetic division.Which answer shows the correct process? A synthetic division diag

STALIN [3.7K]

Answer:

2x + 9 with a remainder of 45.

Step-by-step explanation:

If the divisor is x-5, use the divisor 5 in synthetic div.

Taking the coefficients 2, -1 and 4 from the dividend, we get:

------------------

5 / 2 -1 4

10 45

--------------------

2 9 49

This tells us that the quotient is 2x + 9 and that the remainder is 49.
