T is equal in both situations ... d = r X t so d/r = t
c is rate of waters current
14(12 - c) = 7(12 + c)
2(12 - c) = 12 + c
24 - 2c = 12 + c
12 = 3c
4 = c The rate of the waters current is 4 miles per hour.
Positive (it's going up)
C
42 years later (8x + 366 = y --> 8x + 366 = 700 --> 8x = 334 --> x = 41.75 --> 42 years)
No. The graph shows that the amount is increasing at a linear rate, not a quadratic one, implying that it will ONLY increase

Answer:
65 grams
Step-by-step explanation:
The formula for an exponential sequence is ...
w(n) = (initial weight) × (1 - (decrease per use))^n . . . . for n uses
w(n) = 95·0.975^n . . . . . filling in the given numbers
Then for 15 uses, the weight is ...
w(15) = 95·0.975^15 ≈ 64.98 ≈ 65
The weight after 15 uses is about 65 grams.
