Step-by-step explanation:
A candle 6 inches high burns at a rate of 1 inch every 2 hours for 5 hours. The candles burning rate is 0.5 inch per hour).
Then
- a cnadle height after first hour is 6 - 0.5 = 5.5 inches;
- a candle height after first two hours is 5.5 - 0.5 = 5 inches;
- a candle height after first three hours is 5 - 0.5 = 4.5 inches;
- a candle height after first 4 hours is 4.5 - 0.5 = 4 inches;
- a candle height after first 5 hours is 4 - 0.5 = 3.5 inches.
The candles height h (in inches) at any time t (in hours) is modeled by

Your answer will be 3x^2-7x.
Answer:
There is no error.
Step-by-step explanation:
3 x 5 equals 15. Good. Now, 3+3+3+3+3 also equals 15. Meaning, that both equations equal the same number, and that the equation is true.
