Will the answer to the expression is -4 but i don't see any arrows <span />
Answer:
A
Step-by-step explanation:
SA = πr² + πrs
r = 4.42
s = 2.61
SA = π(4.42)² + π(4.42)(2.61)
SA = 19.5364π + 11.5362π
SA = 61.34 + 36.22
SA = 97.56
The closest answer would be A.
Best of Luck!
Answer:
0
Step-by-step explanation:
The only value that would make sense is if at least one of the variables (A , B , C , D) is 0 (if not all of them). When multiplied, the answer will still be 0, thereby making the equation true.

Solution :
Let
be the unit vector in the direction parallel to the plane and let
be the component of F in the direction of
and
be the component normal to
.
Since, 


Therefore, 
From figure,

We know that the direction of
is opposite of the direction of
, so we have



The unit vector in the direction normal to the plane,
has components :


Therefore, 
From figure,

∴ 

Therefore,


11z > -33
11z / 11 > 33 / 11
z > 3
Hope it helps!
