The intensity I of light emitted from a light bulb varies inversely as the square of the distance D from the bulb. If the intensity is 108 lumens at a distance of 12 meters, what is the intensity at a distance of 7 meters?

ha!

i just did this!

18. g

20. h 30 degree turn.

21. d 90 degree angles

hope i !

pls mark me brainiest

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1
