Using a linear function, it is found that it will take 13 hours for the candle to burn down to a height of .25 inches.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
Considering the situation described, the y-intercept is of 10 while the slope is of -0.75, hence the height of the candle after t hours is given by:
h(t) = 10 - 0.75t
The height will be of 0.25 inches when h(t) = 0.25, hence:
0.25 = 10 - 0.75t
0.75t = 9.75
t = 9.75/0.75
t = 13 hours.

For this, we will be using the pythagorean theorem, which is 
. Since we have the hypotenuse and one of the legs, we can solve for the other leg. Our equation will look like this: 
Firstly, solve the exponents: 
Next, subtract 3600 on both sides: 
Next, square root both sides, and your answer will be x = 80 units
The answer is a. hope this helps
