level after I day was 5380 bacteria per cubic centimeter.
Answer: the function N(t) to estimate the level of contamination in the lake is:
N(t) = -1110 ln(t) - 230t + 1110 ln(I) + 230I + 5380
Step-by-step explanation: ∫ dN/dt dt = ∫ (-1110/t² -230) dt
N(t) = -1110 ln(t) - 230t + C
N(I) = -1110 ln(I) - 230I + C = 5380
C = 1110 ln(I) + 230I + 5380
Answer:
3.5 miles
Step-by-step explanation:
From the question, we have the following information:
The super speedway at Daytona International Speedway is = 2.5 miles
long
The road course there is = 1.4 times as long as the super speedway.
How long is the road course?
The length of the road course is calculated as:
1.4 × length of the super speedway
1.4 × 2.5 miles
=>3.5 miles
Therefore, length of the road course I s 3.5 miles.
Answer:
The total length of Valerie’s walls is 105.75 feet:
(2.5 × 4) + (21.25 × 3) + 32 = 10 + 63.75 + 32 = 105.75 feet.
The total length of Seth’s walls is 107 feet:
3.5 + (22.75 × 2) + 58 = 3.5 + 45.5 + 58 = 107 feet.
The sum of 105.75 feet and 107 feet is 212.75 feet. The Commutative Property allows me to add numbers in any order. This is why the answers in parts D and E match.
