One way i got mine back was answering questions of others.
Answer:
the diameter of the outside edge of the receiver is 
Explanation:
From the schematic free body diagram illustrating what the question is all about below;
Let represent A to be the vertex where the receiver is being placed
S to be the focus
BP to be equal to r (i.e radius of the outer edge)
BC to be 2 r (i.e the diameter)
Given that AS = 4 in and AP is 18 in
Let AP be x- axis and AY be y -axis
A=(0,0)
S=(4,0) = (0,0)
So that the equation of the parabolic path of the receiver will be:

B = (AP, BP)
B = (18, r)
B lies y² = 16 x
r² = 16 x
r² 16 × 18

Diameter BC = 2r

Answer:
B. Electrical to kinetic
Explanation
Since the mixer uses electricity to function, which in turn spins the blades, it converts electricity into kinetic energy.
