Answer:
15
Step-by-step explanation:
Distance between two points is = √(x2 - x1)² + (y2 - y1)²
x1 = -5, y1 = 4; x2 = 7, y2 = -5
|PQ| = √(7 - (-5))² + (-5 - 4)²
|PQ| = √(7 + 5)² + (-9)²
|PQ| = √(12)² + 81
|PQ| = √144 + 81
|PQ| = √225
|PQ| = 15
The first question answer is 21*10^7
The second question answer is 5*10^2
Answer:
(-2,-3)(0,-5)(3,-8)
Step-by-step explanation:
(-3)^2 +(-4)^2. =x^2
9+16= 25= 5^2
Radius =5
Answer:
Diameter is 10
