PLEASE HELP!! SOLVE FOR 7,8,9 IN PART 1 ACTUAL ANWSWERS DONT STEAL MY POINTS!!!! I WILL GIVE BRAINEST TO CORRECT ANWSER

Answer 1

Answer:

Given formula:

• d = (21.9) $2^{(20-x)/12}$

1.

Find d(7), d(8) and d(9)

• d(7) = (21.9) $2^{(20-7)/12}$ = (21.9) $2^{13/12}$   ≈ 46.404
• d(8)  = (21.9) $2^{(20-8)/12}$ = (21.9) $2^{12/12}$  = 43.8
• d(9) = (21.9) $2^{(20-9)/12}$ = (21.9) $2^{11/12}$   ≈ 41.342

2.

The ratios are

• d(9)/ d(8) = 41.342/43.8 ≈ 0.944
• d(8)/(d(7) = 43.8/46.404 ≈ 0.944

As we see the ratios are same. This is due to the exponential nature of the function. 0.944 is the common ratio between two consecutive distances.
