Answer:
1/250 W/m² or 0.004 W/m² or 4 mW/m²
Step-by-step explanation:
The cargo worker is (50 m)/(1 m) = 50 times the reference distance. The intensity varies as the inverse of the square of the distance, so will be ...
(1/50)²×(10 W/m²) = 10/2500 W/m² = 1/250 W/m²
This might be more conveniently written as 4 mW/m².
Answer:
Neither.
Step-by-step explanation:
13 - 1 = 12 and 19 - 13 = 6 - no common difference so its not Arithmetic.
13/1 = 13 and 19/13 = 1.46 - no common ratio so its not Geometric.

Answer:
d. AB = 54
Step-by-step explanation:
The triangle is isosceles, so AB = AC.
(4x +6) = (5x -6)
12 = x . . . . . . . . . . . . add 6-4x to both sides
Then the length of AB is ...
AB = 4x +6 = 4(12) +6 = 48 +6
AB = 54
Answer:
E. 54cm ^2
Step-by-step explanation:
when finding the area just multiply length over width .for example 9 is the length times it to the width 6 you get 54 so the area will be 54 cm
