Question

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

Answer 1

D. 5.7

Explanation:

due to its reflection

Answer 2

D

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)}\\\\=√(16+16)\\\\=√(32)\\\\=√(2*2*2*2*2)\\\\=2*2√(2)=4√(2)`

= 4 * 1.4142

= 5.6568

= 5.7
