c)14
Step-by-step explanation:
Answer:
Total temperature change = -32.48 degrees
Step-by-step explanation:
Over 11.2 hours, the temperature changed -2.9 degrees each hour.
Total time elapsed = 11.2 hour.
Temperature change per hour = -2.9 degrees
Total temperature change = Total time elapsed x Temperature change per hour
Total temperature change = 11.2 x -2.9 = -32.48 degrees
So temperature is reduced by 32.48 degrees in 11.2 hours.
Total temperature change = -32.48 degrees
Answer:
264cm^3
Step-by-step explanation:
8 × 5 × 5 = 200
8 × 1 × 8 = 64
200 + 64 = 264
When working with functions (of all types), the average rate of change is expressed using function notation:
For the interval from x=7 to x=8,
1. find f(7) and f(8):
2. use given formula:
Answer: the average rate of change for the interval from x=7 to x=8 is 4374.
