Answer: temperature and weight
Step-by-step explanation: Temperature can increase or decrease/can go up and down without moving. The same goes with weight, it can go up or down without moving.
The answer is 62^ it reflects angle IK
I created this using a graphing calculator website called Desmos! You can use this to further explore slopes and lines and graphing in general :)
Answer: 
Step-by-step explanation:
We are told the wind turbine makes 76 revolutions in 1 minute. This means the angular speed
of the object in revolutions per minute (rpm) is:
(1)
However, we have to convert this to
, since this is the unit used in the International Systme of Units for angular speed.
So, we can do this knowing that:
(2)
Where:
is the value of one revolution
is the period of rotation
With this information in mind, let's make the conversion:
(3)
(4) This is the wind turbine angular speed
DE + EF = 4x+2
DE = x+7
EF = 7
Substitute these in
x + 7 + 7 = 4x + 2
x + 14 = 4x + 2
subtract x from both sides
14 = 3x + 2
subtract 2 from both sides
3x = 12
divide both sides by 3
x = 4
substitute this in to find the length of DE
DE = x + 7
(4) + 7 = 11
the answer is 11
