10. What is the distance between (8,7) and (3,-5)?

Anarel [89]

Answer:

distance between points=13 units

Step-by-step explanation:

distance between points= $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

put $(x_1,x_2)$ =(8,7) and $(y_1,y_2)$ =(3,-5)

distance between points= $\sqrt{(3-8)^2+(-5-7)^2}$

distance between points= $\sqrt{(-5)^2+(-12)^2}$

distance between points= $\sqrt{25+144}$

distance between points= $\sqrt{169}$

Answer:

explained

Step-by-step explanation:

hence according to above explanation, the arrangement from greatest to least

$2.2\times10^5$

$5.0\times10^4$

$3.6\times10^{-2}$

$8.5\times10^{-6}$

$9.5\times10^{-6}$
