5x^2 + 45 - 7x - 63 which simplifies to 5x^2 -7x -18?
It would be 1/4 of the original volume
1,000 + 1 =1,001 + 2 = 1,002
I hope this helps
Answer:
63.5 feet/minute
Step-by-step explanation:
She first descended 1,024 feet in 17 minutes
Then she descended 500 feet in 7 minutes
The total feet descended is 1,024 + 500 = 1,524 feet
The total time to descend is 17 + 7 = 24 minutes
The average rate of change in altitude is
Altitude descended / time
1,524 feet / 24 minutes
63.5 feet /minute
