The rate of the plane in still air is 870km/h and the rate of the wind 210km/h.

<h3>What is speed?</h3>

Speed has the dimensions of distance divided by time.

Let Speed of airplane be x km/h and Speed of Wind be y km/h

Speed direction of wind (x+y)

Speed in opposition of wind (x-y)

Now, using speed x time= distance

7( x-y)=4620

(x-y)=4620/7

=660------------------(1)

Similarly,

8(x+y)=8640

(x+y) =8640/8=1080-----------------------(2)

Adding (1) and (2)

2x=1740

x=870 km/h

Subtracting (1) from (2)

2y=420

=>y=210 km/h

So rate of airplane =870km/h

rate of wind=210km/h

Hello!!!

The Graph's Answer is below

<u>Nicole's Pattern                   Ian's Pattern               Coordinate's Plane               </u>

 1                                                 0                                   ( 1,0)

5                                                 1                                   (5,1)

17                                                3                                 (17,3)    

53                                               7                                (53,7)    

161                                               15                              (161,15)

In order to get these answers, you start with 1 one Nicole's equation, and mutliply by 3, which gets you three. You then add two, which gets you five, after this, you continue to add Nicole's answer by three, then add five.For Ian's answer,you start with 0,then you add 1/2, which gives you .5 After you have this .5 you multiply by 2,which gives you one whole, you continue to add a half and mutliply by 2 for each answer. Nicole's answer is X,which means it is used first in our parentheses ( ),while ian's is Y and is used second.

I HOPE THIS HELPS! Good luck on your assignment and let me know if you need help with anything else <3!
