So this would be F(-9)=-(-9)(2)-10(-9)-2 --------
9(2)-10(-9)-2 ----------- 18+90-2 ----------- 108-2+ 106.
So the answer to this equation is 106.

(1 point) let a=⟨−4,−3,2⟩a=⟨−4,−3,2⟩. find a unit vector in the same direction as aa.
sergij07 [2.7K]
A unit vector in the direction of a would be the vector a multiplied by a factor such that the length of vector a is unity.
The magnitude of a is given by:
|a|
=sqrt(4^2+3^2+2^2)   [ I got lazy instead of writing (-4)^2+(-3)^2+2^2]
=sqrt(29).

So the univector is a/sqrt(29), or (-4/sqrt(29),-3/sqrt(29), 2/sqrt(29), or simply (-4,-3,2)/sqrt(29).

Find all the real square roots of a. .0064 and b. -.0081
nirvana33 [79]
Answers:  0.08 and -0.08; 0.09i and -0.09i.

When taking square roots, we take the positive and negative answers.  This gives us the first answer.

For the second answer, we rewrite -0.0081 as a complex number:
\sqrt{-0.0081}=\sqrt{0.0081i^2}=i\sqrt{0.0081}=\pm0.09i
