The distance between the points (–3,k) and (2, 0) exists k = ± 3.
How to estimate the distance between points (–3, k) and (2, 0)?
To calculate the distance between two points exists equal to
![$d=\sqrt{(y 2-y 1)^{2}+(x 2-x 1)^{2}}$](https://tex.z-dn.net/?f=%24d%3D%5Csqrt%7B%28y%202-y%201%29%5E%7B2%7D%2B%28x%202-x%201%29%5E%7B2%7D%7D%24)
we have (-3, k) and (2, 0)
![$&d=\sqrt{34}](https://tex.z-dn.net/?f=%24%26d%3D%5Csqrt%7B34%7D)
substitute, the values in the above equation, and we get
![$\sqrt{34} &=\sqrt{(0-k)^{2}+(2+3)^{2}} \\](https://tex.z-dn.net/?f=%24%5Csqrt%7B34%7D%20%26%3D%5Csqrt%7B%280-k%29%5E%7B2%7D%2B%282%2B3%29%5E%7B2%7D%7D%20%5C%5C)
simplifying the above equation
![$\sqrt{34} &=\sqrt{(-k)^{2}+(5)^{2}} \\](https://tex.z-dn.net/?f=%24%5Csqrt%7B34%7D%20%26%3D%5Csqrt%7B%28-k%29%5E%7B2%7D%2B%285%29%5E%7B2%7D%7D%20%5C%5C)
![$\sqrt{34} &=\sqrt{k^{2}+25}](https://tex.z-dn.net/?f=%24%5Csqrt%7B34%7D%20%26%3D%5Csqrt%7Bk%5E%7B2%7D%2B25%7D)
squared both sides
![$&34=k^{2}+25 \\](https://tex.z-dn.net/?f=%24%2634%3Dk%5E%7B2%7D%2B25%20%5C%5C)
![$&k^{2}=34-25 \\](https://tex.z-dn.net/?f=%24%26k%5E%7B2%7D%3D34-25%20%5C%5C)
![$&k^{2}=9 \\](https://tex.z-dn.net/?f=%24%26k%5E%7B2%7D%3D9%20%5C%5C)
k = ± 3
Therefore, the value of k = ± 3.
