Answer:
The rate of the plane is 862 miles per hour
Step-by-step explanation:
An airplane travels 6903 kilometers against the wind in 9 hours.
Speed = distance / time
Speed of the airplane while travelling against the wind is
6903/9 = 767 miles per hour
The airplane travelled 8613 kilometers with the wind in the same amount of time. This means that the speed while travelling with the wind will be
8613/9 = 957 miles per hour
Let x = speed of the airplane
Let y = speed of the wind
While travelling against the wind,
x - y = 767 - - - - - -- 1
While travelling with the wind,
x + y = 957 - - - - - - -2
Subtracting equation 2 from equation 1,
-y - y = 767 - 957
-2y = -190
y = -190/-2
y = 95 miles per hour
x = 957 - y
x = 957 - 95
x = 862 miles per hour
If the pendulum is 40 inches long, its tip moves 13.96” each second.

Step-by-step explanation:
The formula for slope is rise/run there a whole lot of variations of it tho see
(Srry abt my hand writing XD)
rise is basically how far away are the 2 y values from each other
(It will always be positive btw mate.
In this case the rise would be 5
because you need to move up 5 spaces to reach 3 from -2
Now the run which is how far away the 2 x values are from each other.
In this case it would be 4
because you need to move 4 spaces from 3 to reach 7
so it would the slope would be 5/4 :)
This may not be right but you can get the just of how to do it hopefully
Im learning this right now too XD
You can use 5/10 and 50% which is the same as 0.5%
