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
The domain of this function is
The range og this function is
H(x) has a constant output of –2.50.
As x increases, g(x) increases.
g(x) is greater than –2.50 for x values less than –1.
h(x) is less than –2.50 for x values greater than –2.
The input value for which g(x) = h(x) is between –1 and 0.
Answer:
Let's solve your equation step-by-step.

Answer:
No real solutions.
You have to use the y=mx+b formula to find the equation
Answer:
15.13 cm
Step-by-step explanation:
We are given:
Lateral surface area of a right circular cone : πr√r² + h²
From the question, we know that:
Lateral surface area = 236.64cm²
Radius = 4.75cm
Height = ?
Making h the subject of the formula
h = √[(A/r)² - πr²]/π
h = √[(236.64/4.75)² - π ×4.75²]/π
h = √(2481.9275169 - 70.882184247)/π
h = 15.12975 cm
Approximately to the nearest hundredth = 15.13cm
