Answer:The equation relating I, r, and k is I =K/r²
Step-by-step explanation:
The intensity, I, of a sound varies inversely with the square of the distance, r, from the source of the sound can be written as
I ∝ 1/r²
Introducing the constant of proportionality, K we have that
I =K x 1/r²
Therefore , the equation relating I, r, and k is I =K/r²
Answer:
Answer:36
18×2= 36 because if each got halfed, each half would equal one sandwich so there would be 36 sandwiches
135 degrees.
Assuming that it is a regular octagon, you can use the formula (n-2) (180) divided by n. n = sides. Therefore, (8-2) (180) divided by 8, which is 135.
y= -x-5
m=1-(-5)/-4-2
m=-1
-1= -x
y=-x-5
