Answer:
F(v)=0
Step-by-step explanation:
F(v) = [3x*2y, 5xx, 9yy]
Calculate the product
F(v) = [3x*2y, 5x*x, 9y*y]
The derivative of a constant is always 0
F(v) =((6xy,5,9))
f(v)=0
Answer:
(- 7, - 3 )
Step-by-step explanation:
Under a clockwise rotation about the origin of 90°
a point (x, y ) → (y, - x ), thus
(3, - 7 ) → (- 7, - 3 )
Multiply, and Divide
2/ 2 - 15i
2(2 + 15i)/ (2 - 15i) * 2 + 15i
= ( 4 + 30i)/ (4 + 225)
= (4 + 30i )/ 229
Hence; 2/ 2 - 15i
= 4/ 229 + 30i/ 229
Therefore, Letter Choice (D); is your answer 4/229 + 30i/229
Hope that helps!!!!
