What is the focus of the parabola? y=−14x2−2x−2 Enter your answer in the boxes.

Sloan [31]

Answer:

Step-by-step explanation:

Given is a parabola

$y=-14x^2-2x-2$

Let us rewrite this in vertex form

$y=-14(x+\frac{1}{14})^2-\frac{27}{14}$

Hence vertex = $(\frac{-1}{14} ,\frac{-27}{14} )$

Axis of symmetry is

$x=-\frac{1}{14}$

a= $\frac{1}{(14)4} =\frac{1}{56}$

Hence focus would lie on the line of symmetry at a distance of a from vertex

So focus = $(-\frac{1}{14} ,-\frac{27}{14} -\frac{1}{56} )\\=(-\frac{1}{14} , -\frac{109}{56} )$

Montano1993 [528]

Answer:

400 meters

0 meters if the puppy can jump really really far ha ha ....

P = 10000x - 100

T = 8000x

10000x - 100 = 8000x

2000x = 100

x = 1/20 hr

60/20 = 3 minutes
