The correct option D; models the depth of the submarine.

<h3>Define the term parabola?</h3>
  • Parabola, also known as an open curve or conic section, is formed when a right circular cone and a plane perpendicular to one of the cone's elements cross.

When a submarine is x miles out of its launch place, we need to figure out which table best represents the depth of the submarine using the function d, wherein d(x) is the depth, in meters.

Both x = 5 as well as x = 40 have zeros.

Since it's a parabola,

D(x) = a(x-5)(x-40)

vertex = (22.5, -146)

Thus,

-146 = a(22.5-5)(22.5-40)

a = -146/(22.5-5)(22.5-40)

a = 0.4767

Put value of a in equation.

D(x) = a(x-5)(x-40)

D(x) = 0.4767(x-5)(x-40)

The equation above is quadratic function model.

We can see from the graph that:

(5) and (0), respectively, are points on the graph (40,0).

Consequently, if x = 5 when y = 0, then.

y(min) > -160.

Additionally, the table in option (D) represents the submarine's depth.

Explain how you would convert a measurement given in ounces into pints
Greeley [361]
8 ounces = 1cup
2 cups = 1 pint
So, 16 ounces = 2 cups = 1pint
16 ounces = 1 pint

If you have 8 ounces, you would have half a pint.
If you have 20 ounces:
20 ounces/16 ounces= 5/4
So, you'd have 1 1/4 or 1.25 pints

In 1935, there were 15,295 banks in the United States. In 2003 there were 9,182 banks. What is the percent of the change? Is it
Sati [7]
If it goes from a higher number to a lower number it is a decrease.

(15,295 - 9182) / 15295....x 100
6113 / 15295 = 0.399....x 100 = 39.9% decrease

£140 is divided between Angad, Nick &amp; June so that Angad gets twice as much as Nick, and Nick gets three times as much as Ju
Vladimir79 [104]

Answer:

  £84

Step-by-step explanation:

The given ratios are ...

  A : N = 2 : 1

  N : J = 3 : 1

Putting these together, we have ...

  A : N : J = 6 : 3 : 1

There are a total of 6+3+1 = 10 ratio units, so each is worth £140/10 = £14.

Angad's share is 6×£14 = £84.

_____

<em>Check</em>

Nick gets £42, and June gets £14. Together, they share £84 +42 +14 = £140.
