Answer:
The answer is -20.
Step-by-step explanation:
(8 × 5) - (-6 × -10)
= 40 - 60
= -20
Answer:
a.
Step-by-step explanation:
The given vector is v= 4i - 5j
The magnitude of this vector is;
The unit vector u in the direction of v is;
We rationalize to get
2.
M must be (0,0) since it coincides with the origin
R must be (a+b, √(a²-b²)).
The x-coordinate is b from A translated to the right by a.
The y-coordinate is the same as A.
(I think the square root is there to confuse you).
3.
R(0,0)
C(a,b) (same x as T, same Y as E)
5.
Not sure how to prove that.
2 x (3+6z) = 6 +12z
This is how you do it
