Alexus [3.1K]3 years ago

Answer:

C. None of the above

Step-by-step explanation:

You can get the equivalent expression by simplifying the expression above.

  • 5+(-3)(6x-5)
  • 5+ (-18x+15)
  • 5-18x+15
  • -18x+20

-18x+20 is not the same with 18x-20, therefore A is not a correct answer.

For example, the value of x is 2.

  • -18(2) + 20 = ?                    
  • -36 + 20 = ?
  • -16
  • 18(2) - 20 =?
  • 36 - 20 = ?
  • 16

<em>-16 and 16 are not the same</em>

11. Rocco and Biff are two koalas sitting at the
bagirrra123 [75]

Answer:

Biff's tree is 14 m off the ground and Rocco's tree is 7 m off the ground.

Step-by-step explanation:

Let the height of Biff's tree be represented by x, so that the height of Rocco's tree is \frac{x}{2}.

Draw a straight line from Rocco's point of view to a point t to the middle of Biff's tree. This line divides x into two equal parts, and the angle is divided into 35^{0} each.

By alternate angle property,

Tan  35^{0} = \frac{\frac{x}{2} }{10}

\frac{x}{2} = Tan  35^{0} × 10

  = 7.00021

⇒       x = 2 × 7.0021

            = 14. 0042

         x = 14

Therefore, Biff's tree is 14 m off the ground and Rocco's tree is 7 m off the ground.

The equation for free fall at the surface of some planet (s in meters, t in seconds) is s=2.86t^2. How long does it take a rock
kotykmax [81]

The time taken by the rock will be 8.77 seconds.

<h3>What is speed?</h3>

Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance.

Given that:-

The equation for free fall at the surface of some planet (s in meters, t in seconds) is s = 2.86t²

The time will be calculated by using the speed formula.

Speed = Distance \ Time

25.1   = 2.86t² \ t

t   =  25.1 / 2.86

t   =  8.77 seconds

Therefore the time taken by the rock will be 8.77 seconds.
