Question

What is the distance between points A and E? A. 2.8 B. 3.2 C. 4.9 D. 5.7

Answer 1

Answer:

D. 5.7

Step-by-step explanation:

due to its reflection

Answer 2

Answer:

D

Step-by-step explanation:

A(3, 4)   ;     B(-1 , 0)

Distance= $\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

              = $\sqrt{(-1-3)^{2}+(4-0)^{2}}\\\\=\sqrt{(-4)^{2}+(4)^{2}}\\\\=\sqrt{16+16}\\\\=\sqrt{32}\\\\=\sqrt{2*2*2*2*2}\\\\=2*2\sqrt{2}=4\sqrt{2}$

                = 4 * 1.4142

               = 5.6568

               = 5.7
