Answer:
Expression that represents distance between points (a,0) and (0,5) is:
[tex]\sqrt{a^2+5^2}[/tex]
Step-by-step explanation:
The distance between points (x1,y1) and (x2,y2) is given by:
[tex]\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]
Here, (x1,y1)=(a,0) and (x2,y2)=(0,5)
[tex]\sqrt{(0-a)^2+(5-0)^2}[/tex]
= [tex]\sqrt{a^2+5^2}[/tex]
Hence, expression that represents distance between points (a,0) and (0,5) is:
[tex]\sqrt{a^2+5^2}[/tex]
