Answer: 17.09

Step-by-step explanation:

Given:  The ordered pair that represents the vector from A(-9 9) to B(7 3).

The length of vector from points (x_1,y_1) and  (x_2,y_2)  is given by  using distance formula:-

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Now, the length of vector AB is given by:-

AB=\sqrt{(7-(-9))^2+(3-9)^2}\\\\=\sqrt{(7+9)^2+(-6)^2}\\\\=\sqrt{(16^2)+36} \\\\=\sqrt{256+36} \\\\=\sqrt{292}=17.0880074906\approx17.09

Therefore, the magnitude of Ab = 17.09

Moving from a to b, the x component  of the desired vector is 7-(-9) = 16, and
the y component is 3-9 = -6.

So the vector from a to b is <16,-6>, and the magnitude is

sqrt(16^2 + (-6)^2 ), applying the Pythagorean Theorem.

Answer: -5/21.

Step-by-step explanation:

\frac{2}{5}*[\frac{-3}{7} +(\frac{-1}{6})]=\frac{2}{5} *(-\frac{3}{7} -\frac{1}{6}) =\frac{2}{5}*(-\frac{3*6+1*7)}{7*6}  )=\frac{2}{5}*(-\frac{18+7}{42})=\frac{2}{5}*(-\frac{25}{42})=-\frac{5}{21} .

Good luck an' have a nice day!
