-5
Step-by-step explanation:
The real part of -5 + 3i is -5, and the imaginary part is 3.
Answer:
The answer would be B hope this works
1/3 (3y - 6) = 8
distribute: y - 2 = 8
add 2 to both sides: y = 10
10
Answer:
1116
Step-by-step explanation:
3*380 = 1140
1140 - 24 = 1116
Answer:
77.2 milliroentgens per hour
Step-by-step explanation:
The first step is to find the constant of proportionality
I ∝ 1/d²
I = k/d²
62.5 = k/(3)²
k = 562.5
The second step is to calculate the intensity at 2.7 meters:
I = 562.5/d²
I = 562.5/(2.7)²
I = 77.2 milliroentgens per hour
