Questions: Raw cake batter starts at a thickness of 2 centimeters in a pan but grows at 0.15 centimeters every minute in the oven. How tall will the cake be after a certain number of minutes?
Raw cake batter starts at a thickness of 2 centimeters in a pan but grows at 0.15 centimeters every minute in the oven. How tall will the cake be after a certain number of minutes?
Solution
Solution Steps
Step 1: Identify the initial thickness of the cake batter
The initial thickness of the cake batter is given as 2 centimeters. This is the starting point before any growth occurs.
Step 2: Determine the growth rate of the cake batter
The cake batter grows at a rate of 0.15 centimeters every minute. This is the slope of the linear equation that describes the growth of the cake over time.
Step 3: Formulate the linear equation
The height of the cake \( y \) after \( x \) minutes can be expressed as:
\[
y = 0.15x + 2
\]
Here, \( 0.15x \) represents the growth over \( x \) minutes, and \( 2 \) is the initial thickness.
