The distance between two points J and K is 13 unit (approx)

Step-by-step explanation:

Given,

Two points are J(3,0) and k(6,-13).

To find the distance between J and K.

Formula

The distance between two points (x_{1} ,y_{1}) and (x_{2} ,y_{2}) is \sqrt{(x_{2}-x_{1} ) ^{2}+(y_{2}-y_{1} ) ^{2}  }

Now,

Putting, x_{1} = 3, y_{1}=0,  x_{2}=6,  y_{2}=-13 we get,

JK = \sqrt{(6-3)^{2} +(-13-0)^{2} }

= \sqrt{178}  unit = 13.34 unit (approx)

JDK-right triangle. JD=13, DK=3

By the Pythagorean theorem

13^2+3^2=JK^2\\JK=\sqrt{169+9} \\JK=\sqrt{178} \\

JK≈13,34

Answer: the distance is 13 units

Choose the simplified form of  the fifth term of 6C4(2x)2(-y2)4.​
Katarina [22]

You didn't give us the choices.   It doesn't matter.  I think you're trying to write

\displaystyle {6 \choose 4} (2x)^2 (-y^2)^4

= \dfrac{6!}{4! 2!} ( 4x^2 y^8)

= \dfrac{6(5)}{2} ( 4x^2 y^8)

=60x^2 y^8

Answer: 60 x² y⁸
