Across a horizontal distance of 25 feet, a roller coaster has a steep drop. The height of the roller coaster at the bottom of th
I am Lyosha [343]

Answer:

<em>For each horizontal foot, the roller coaster changes </em><em>6 feet</em><em> of height.</em>

Step-by-step explanation:

Across a horizontal distance of 25 feet, a roller coaster has a steep drop.

So the run is 25 feet.

The height of the roller coaster at the bottom of the drop is -150 feet. (Negative sign is given because it is measured from the top to bottom)

So the rise is 150 feet.

The slope of the roller coaster is,

m=\dfrac{\text{Rise}}{\text{Run}}=\dfrac{150}{25}=6

Slope of 6 means, for 1 unit of run, the object has a rise of 6 units.

Therefore, for each horizontal foot, the roller coaster changes 6 feet of height.

  • Definition of a Line: A line is 180°

Step-by-step explanation:

<u>Step 1: Set up Equation</u>

m∠BDC + m∠CDA = 180°

(-7x + 12)° + (-8x + 48)° = 180°

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Combine like terms:                    -15x + 60 = 180
  2. Isolate <em>x</em> term:                              -15x = 120
  3. Isolate <em>x</em>:                                       x = -8

<u>Step 3: Find m∠BDC</u>

  1. Define:                    m∠BDC = (-7x + 12)°
  2. Substitute in <em>x</em>:       m∠BDC = (-7(-8) + 12)°
  3. Multiply:                  m∠BDC = (56 + 12)°
  4. Add:                        m∠BDC = 68°
