A photo booth’s profit as a function of users is represented in the table. The function is quadratic.
Luda [366]

Answer:

The vertex represent the minimum amount of profit

Step-by-step explanation:

Plot the function to better understand the problem

Let

x ----> the number of users in thousands

y ---> the Monthly profit in thousands

using a graphing tool

see the attached figure

we have a vertical parabola open upward

The vertex represent a minimum

In the context of this problem

The vertex represent the minimum amount of profit

In this problem the vertex is the point (0.4,-4)

0.4 represent -----> 0.4(1,000)=400 users

-4=-4(1,000)=-$4,000 (profit negative)

The perimeter of a rectangle is equal to 163 yard. The width is 8 more than twice the length. Find the length and width.​
Sedaia [141]

Answer:

l = 29.4 yards

w = 66.8 yards

General Formulas and Concepts:

  • Order of Operations: BPEMDAS
  • Perimeter of a Rectangle: P = 2w + 2l

Step-by-step explanation:

<u>Step 1: Define</u>

P = 163 yards

w = 2l + 8

l = l

<u>Step 2: Set up equation</u>

P = 2w + 2l

163 = 2(2l + 8) + l

<u>Step 3: Solve for </u><em><u>l</u></em>

  1. Distribute 2:                              163 = 4l + 16 + l
  2. Combine like terms:                 163 = 5l + 16
  3. Subtract 16 on both sides:        147 = 5l
  4. Divide both sides by 5:             147/5 = l
  5. Rewrite:                                      l = 147/5
  6. Evaluate:                                    l = 29.4 yards

<u>Step 4: Find </u><em><u>w</u></em>

  1. Define:                    w = 2l + 8
  2. Substitute:              w = 2(29.4) + 8
  3. Multiply:                  w = 58.8 + 8
  4. Add:                        w = 66.8 yards
