Answer:

202m

Step-by-step explanation:

Complete question

(A zip line starts on a platform that is 40 meters above the ground. The anchor for the zip line is 198 horizontal meters from the base of the platform.

How long is the zip line? See attached diagram for illustration)

Using pythagoras theory

Y = 40

Z = 198

X =?

X² = y² + z²

X² = 40² + 198²

X² = 40804

X = 202m

The zip line is 202m

1. Given line segment RB and on it is point C, if RB = 45 and CB = 3x - 12 and RC = 2x + 9, what is the value of x?
marshall27 [118]

Answer:

Step-by-step explanation:

1). If a point C is lying on a line segment RB,

   Then RB = RC + CB

   Since, RB = 45, CB = 3x - 12 and RC = 2x + 9

   45 = (2x + 9) + (3x - 12)

   45 = (2x + 3x) - 3

   48 = 5x

   x = \frac{48}{5}

   x = 9.6

2). Since, RC = 2x + 9

    RC = 2(9.6) + 9

          = 19.2 + 9

          = 28.2 units

3). Distance between the two points (x_1,y_1) and (x_2,y_2) is given by the formula,

  d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

  Distance between the points A(2, -2) and D(-2, 2) will be,

 AD=\sqrt{(2+2)^2+(-2-2)^2}  

         = \sqrt{16+16}

         = 4\sqrt{2}  

         = 5.657

         ≈ 5.66 units

Find the derivative of <br> y = 1/ (3x^3) with steps
Ganezh [65]

Answer:

- 9 {x}^{ - 4}

Step-by-step explanation:

y =  \frac{1}{ {3x}^{3} }  =  {3x}^{ - 3}

y =  <  - 3 \times 3 >  {x}^{ - 3 - 1}  \\  =  - 9 {x}^{ - 4}
