I think it's:
The circle moves down.
It seems the most logical when I did the math and treated the equations you gave as functions. The function moved down when I put it in a graphing calculator.
Answer:
profit%=35%
Let cp be x
profit =$280
To find cost price of a refrigerator use formula
profit%=profit/cost price *100
35%=$280/x*100
35%=$28000/x
35*x=$28000
x=$28000/35
x=$800
now to find the selling price of a refrigerator use formula
selling price=cost price +profit
=$800+$280
=$1080
Step-by-step explanation:
therefore the cost price of a refrigerator is $800 and selling price is $1080
Answer: The greatest distance, in feet is the first one 3ft.
sin(α) = ⁻⁵/₁₃
sin⁻¹[sin(α)] = sin⁻¹(⁻⁵/₁₃)
α ≈ 1.1256π
cos(β) = ²/₅
cos⁻¹[cos(β)] = cos⁻¹(²/₅)
β ≈ 1.6311π
sin(α - β) = sin(1.1256π - 1.6311π)
sin(α - β) = sin(-0.5055π)
sin(α - β) = -sin(0.5055π)
sin(α - β) = -sin(90.99)
sin(α - β) ≈ -0.116
Student 4 has the largest percent error.
Step-by-step explanation:
The percent error of a measurement is given by

where
x is the value of the measurement
is the actual value
For student 1:

Percent error:

For student 2:

Percent error:

For student 3:

Percent error:

For student 4:

Percent error:

So, student 4 has the largest percent error.
