Answer:
k= -5
Step-by-step explanation:
When x=1 and y= -2,
x-2y+k=0
1 -2(-2)+ k=0
1+4+k=0
5+k=0
k= -5

Answer:
1)
Area
2)
1/2
3)
Radius
Step-by-step explanation:
We know that for any circle with radius r the formula for the area and circumference of the circle is given as:
Area of circle=πr².
and circumference of circle = 2πr.
Hence, to describe the relationship between the area of a circle and its circumference.
The Area of circle is 1/2 times the radius times the circumference.
( Since,
Area=1/2 × r× 2πr
Area=πr² )

It would take 20 hours since 8,000 times 5 is 40,000 so 4 times 5 is 20.
Logic.
