The length at time t is modeled as
The rate of change of the length is
When t = 7 years,
Answer: -0.8882 cm/year
Answer:
Step-by-step explanation:
Let the width be X ft
Length = 2x - 40
Total area = 33,600 sq.ft
length * width = 33,600
(2x - 40) * x = 33,600
2x² - 40x -33600 = 0
Answer:
tip: 15.25; each person paid $22.88 (that is rounded up from 22.875)
There is a total of 31 marine lives in the fish tank. The probability of picking a goldfish is 24/31 since there are 24 goldfish. Further, the probability of picking an angel fish is 2/31 as there are 2 angel fish in the tank. The final probability is the sum of the two probabilities,
P = (24/31 + 2/31) = 26/31
The answer is 26/31.
