The units of speed are miles per hour. You get that by dividing miles by hours:
  (270 mi)/(4.5 h) = 60 mi/h

Answer:

B. Funds need to be easily accessible.

Step-by-step explanation:

We need to understand what is "rainy day", it is an idiom we use to describe a unexpected difficult situation that may happen, that is why we need to "save for a rainy day"

It important for a rainy-day fund to be highly liquid,  it is an financial concept, the degree to which an asset can be bought or sold in the market without significantly affecting its market price such as cash, gold, CD... Which means the asset must be easy to access.

So in a rainy day, we need to response as soon as possible to handle the difficulty.

Hope it will find you well.

4. The directrix of the parabola 12(y + 3) = (x-4)2 has the equation y=-6. Find the coordinates of
Sveta_85 [38]

The coordinates of the focus of the parabola are (4 , 0)

Step-by-step explanation:

The standard form of the equation of the parabola is  

(x - h)² = 4p(y - k), where

  • The vertex of the parabola is (h , k)
  • The focus is (h , k + p)
  • The directrix is at y = k - p

∵ The equation of the parabola is 12(y + 3) = (x - 4)²

 - The form of the equation is (x - h)² = 4p(y - k), compare

    between them to find h, k and p

∴ h = 4

∵ - k = 3

- Multiply both sides by -1

∴ k = -3

∵ 4p = 12

- Divide both sides by 4

∴ p = 3

∵ The coordinates of the focus are (h , k + p)

∵ h = 4 , k = -3 , p = 3

∴ k + p = -3 + 3

∴ k + p = 0

∴ The focus is (4 , 0)

The coordinates of the focus of the parabola are (4 , 0)
