Answer:
The distance from an edge of a circle to another edge
Step-by-step explanation:
Answer:
(A) 509.78
We need to move the decimal point after the first non-zero digit
So,
=> 5.0978 × 10² (Since the decimal point is moved two places to the left)
(B) 0.0289
Again after the first non-zero digit:
So, it becomes:
=> 2.89 × 10⁻² (Since the decimal point is moved 2 places to the right so it will be negative also)
2.8-(-5.1)
-(-5.1)=5.1
2.8+5.1= 7.9
Is this what you were asking?
Answer:
y = -x
Step-by-step explanation:
The line has a slope of -1 and it passes through point (0,0)
Taking another point (x,y) on the line;
Slope = change in y ÷ change in x
For our case; slope = 
Cross multiplying this gives;
y = -x
