Allushta [10]

Answer:

Bess has been keeping track of the storm for 14 hours.

Step-by-step explanation:

The tropical storm has been moving at 15 miles per hour.

Bess recorded that the storm moved 135 miles yesterday and 75 miles today. Total distance covered by storm is

$135+75=210$

The relationship between distance speed and time is defined as

$speed=\frac{distance}{time}$

$15=\frac{210}{time}$

$time=\frac{210}{15}$

$time=14$

Therefore, Bess has been keeping track of the storm for 14 hours.

Write the equation for a parabola with a focus at ( 7, 2) and a directrix at y = -2<br> y = ?

horrorfan [7]

A parabola with an equation, y2 = 4ax has its vertex at the origin and opens to the right.
It's not just the '4' that is important, it's '4a' that matters.
This type of parabola has a directrix at x = -a, and a focus at (a, 0). By writing the equation as it is, the position of the directrix and focus are readily identifiable.
For example, y2 = 2.4x doesn't say a great deal. Re-writing the equation of the parabola as y2 = 4*(0.6)x tells us immediately that the directrix is at x = -0.6 and the focus is at (0.6, 0)
