Answer:
y = 16x
Step-by-step explanation:
False. If x=-3 and y=-6 and you substitute them into the equation they do not add up
1. 864 mm^3
2.1640 cm^3
3. 4.0 cm
4. 150pi ft^3
Answer:
mFG = 67r ( Where r is the radius of the circle)
∠ECF = 67°
Step-by-step explanation:
i) m FG
Join CG
∠GCF=67°
(As FG=ED and equal chords subtend equal angle at center)
Now The length of the minor arc is given by the formula
m arc FG =

∠C=67
m arc FG = 
m arc FG = 67r
Where r is the radius of the circle.
2. ∠ECF = 67°
It is because of the rule which says that equal chords subtend equal angle at center
DE = EF
Hence ∠DCE = ∠ECF
