The half-life of the radioactive substance is 67.95 hours.
After thorough researching, if a jet in calm air conditions travels with velocity vector (389, 389) and the wind velocity (in mph) at the plane’s cruising altitude is given by (0, 50), then the plane’s true speed is 600 mph. The correct answer to the following given statement above is with the letter C.
Answer:
90
Step-by-step explanation:
Answer:
D(-5,3) and E(-5,1)
Step-by-step explanation:
|AB|² = (-1-5)² + (-6-2)²
|AB|² = 36 + 64
|AB|² = 100
|AB| = 10
AB/DE = 5
|DE| = 10/5 = 2
D(-5,3) and E(-5,1)
|DE|² = (-5+5)² + (3-1)²
|DE|² = 4
|DE| = 2

Answers:
1. P=3
Step by step:
P-5=-2 -move the constant to the right hand side and change its sign
P=-2+5 - calculate the sum
P=3
2. W=-2.8
Step by step:
W+13.2=10.4 - move the constant tot he right hand side and change its sign
W=10.4-13.3 - calculate the difference
W=-2.8
3. X=2/3
Step by step:
X-5/6=-1/6 - move the constant to the rig hand side and change its sign
X=-1/6+5/6 - calculate the sum
X=2/3
