Function D models the depth of a submarine where D(x) is the depth in meters. When the submarine is x miles from its launching l
mixer [17]

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.

The Rectangular rug has side lengths of 3 and 4 feet. What is the length of the diagonal?
lesya [120]

the formula to find the diagonal would be

a^2+b^2=c^2

3^2+4^2= 9+16=25

the square root of 25 is 5

5^2=25

so your diagonal is 5 ft

1) How much money will you have in an account after 5 years if you invest $1,200 at 2.5%
Leya [2.2K]

Answer:

$ 1,350

Step-by-step explanation:

i = (prt) / 100

p = $ 1,200 r = 2.5% t = 5 years

i = (1,200 x 2.5 x 5) / 100

i = $ 150

amount = p + i

= 150 + 1,200

= $ 1,350

Suppose there are three types of consumers who attend concerts at your university’s performing arts center: students, staff, and
Alchen [17]

Answer: i. There are 140 students willing to pay $20.

ii. There are 200 staff members willing to pay $35.

iii. There are 100 faculty members willing to pay $50.

Step-by-step explanation: Suppose there are three types of consumers who attend concerts at Marshall university's performing arts center: students, staff, and faculty. Each of these groups has a different willingness to pay for tickets; within each group, willingness to pay is identical. There is a fixed cost of $1,000 to put on a concert, but there are essentially no variable costs.

For each concert:

A) If the performing arts center can charge only one price, what price should it charge? What are profits at this price? B) If the performing arts center can price discriminate and charge two prices, one for students and another for faculty/staff, what are its profits?

C) If the performing arts center can perfectly price discriminate and charge students, staff, and faculty three separate prices, what are its profits?
