Answer 1

Answer:

1. 5√2 units
2. 10
3. 1
4. 3/4
5. cosA
6. 0
7. 2

Step-by-step explanation:

1. Distance Formula $= \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} }$

$= \sqrt{ {(0 - 5)}^{2} + {(0 + 5)}^{2} }$

$= \sqrt{25 + 25} = \sqrt{50}$

$= 5 \sqrt{2}$

2. Distance $= \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} }$

$= \sqrt{ {(0 - 6)}^{2} + {(0 + 8)}^{2} }$

$= \sqrt{36+64} = \sqrt{100}$

= 10
