Use the distance formula: d² = (x₂ - x₁)² + (y₂ - y₁)²
d² = 50² + 80²
= 2500 + 6400
= 8900
d = √8900
= 94.3
Answer: 94.3 km
Answer:
Yes, because 6+9>12.
Step-by-step explanation:
we know that
The <u><em>Triangle Inequality Theorem</em></u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.
so
Applying the triangle inequality theorem
1) 
----> is true
2) 
---> is true
3) 
---> is true
therefore
Yes , Mario can make a triangle with these poles
because, the three poles satisfy the triangle inequality theorem
A=6, b=8, c=10 is the only one i believe. Sorry if I'm wrong.
D because the coordinates of point A are both positive
Answer:
f^-1(x) = 8x/(3-x)
Step-by-step explanation:
y = 3x/(8+x)
x = 3y/(8+y)
x(8+y) = 3y
8x + xy = 3y
8x = 3y - xy
8x = y(3-x)
8x/(3-x) = y
