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.

Given the relation y = x2 + 3x + 2, find the outputs for x = -2, -1, 0, 1, and 2.<br> pls help me
torisob [31]
What you need to do is plug each x value into the equation to find out the corresponding y value.
for example, when x=-2, y=(-2)²+3(-2)+2=4-6+2=0

the outputs are 0, 0, 2, 6, 12

Sin Ф=opposite/ hypotenuse
In this case:
sin 25º=9 in /c
c=9 in/ sin 25º
c≈21.3 in.

Answer: sin (25º), in this case can be used to find the lenght of the hypotenuse, and the length of this hypotenuse would be 21.3 in.
