The number of decibels, d, produced by an audio source can be modeled by the equation d = 10log(I/K) where I is the sound intensity of the audio source and K is a constant. How many decibels are produced by an
audio source whose sound intensity is 1,000 times the
value of K?

4
30
40
100
10,000

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

your answer is the frist one

hop i

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
