A 15-inch candle is lit and burns at a constant rate of 1.2 inches per hour. Let t represent the number of hours since the candl

sergejj [24]

Answer:

$f(t) = 15 -1.2t$

$0 \le t \le 12.5$

$15 \ge f(t)t \ge 0$

The length of the candle (in inches) 3.6 hours after it was lit is 0.95 inches

Step-by-step explanation:

Given

$a = 15$ ---- candle length

$r =- 1.2$ --- rate (it is negative because the candle length reduces)

Solving (a): The function, f(t)

This is calculated as:

$f(t) = a + rt$

So, we have:

$f(t) = 15 + -1.2 * t$

$f(t) = 15 -1.2t$

Solving (b): The domain

The domain, in this case, represents time from 0 till the candle burns out.

Set $f(t) = 0$ to calculate the time the candle burns out

$f(t) = 15 -1.2t$

$0 = 15 - 1.2t$

Collect like terms.

$1.2t = 15$

Solve for t

$t = 15/1,2$

$t = 12.5$

Hence, the domain is: $0 \le t \le 12.5$

Solving (c): The range

The domain, in this case, represents the candle height from 15 till the candle burns out (0 inches)

Hence, the range is: $15 \ge f(t)t \ge 0$

Solving (d): $f(t) = 3.6$

Recall that: $f(t) = 15 -1.2t$

Sp, we have

$15 - 1.2t - 3.6$

Collect like terms

$12t =15 -3.6$

$12t =11.4$

Divide by 12

$t =0.95$
