Answer:
-1 yards
Step-by-step explanation:
5 - 6 = 1
5 yards gained - 6 yards lost = -1 change in yards
Differentiate with respect to x and y
2x +10 y y' = 0
get y' alone
y' = -2x/(10 y)
reduce
y'=-x/(5y)
continue with quotient rule of differentiation
y'' = ( 5y(-1) - (-x) (5y')) / (5y) squared
y'' = (-5y + 5xy') / (25y squared)
reduce by dividing each term by 5
y" = (-y +xy') / (5y squared) answer
Now if the teacher wants you to continue so no y or y' shows
substitute y' = -x/(5y) and y = square root ((5-x squared) / 5)
and simplify
You need to add 2/3 to both sides to get

which simplifies into

Answer:
The ratio must be guaranteed.
Therefore,
18/6 =12/x
=> x= 6*12/18 = 4
Answer:
The first relation is a function because each input only has one output. The second relation is not a function because each output is shared by multiple inputs.
