Jacob strode up 24 steps in 12 seconds to reach his apartment on the second floor. How many steps did he climb in 9.5 seconds?

shutvik [7]

Answer:

He climbed 19 steps

Step-by-step explanation:

Let steps climbed in 9.5 seconds = z

If 24 steps = 12 seconds

then: z = 9.5 seconds

Using criss cross method

24 x 9.5 = 12 x z

228 = 12 z

z = 228/12

z = 19 steps

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

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

so

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

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
