Answer:
9.5 inches per month
Step-by-step explanation:
Given the information about the depth of the pond:
Month 1: 93 in
Month 2: 98 in
Month 3: 112 in
From month 1 to month 3, the average rate of change of the depth of the pond, in inches per month can be calculated using formula
Hence, from month 1 to month 3, what is the average rate of change of the depth of the pond, in inches per month is
Answer:
Step-by-step explanation:
1. Multiply both sides of the equation by the reciprocal of the coefficient of r.
__
2. Multiply both sides of the equation by the reciprocal of the coefficient of h.
__
3. Solve the circumference formula for r, then substitute the given information.
__
4. Solve the perimeter formula for width, the substitute the given information and do the arithmetic.
_____
In general, solving for a particular variable involves "undoing" what has been done to the variable, usually in the reverse order. In part 4, the variable W has L added and the sum is multiplied by 2. We "undo" those operations, last operation first, by dividing by 2 and subtracting L.
The properties of equality say you can do what you like to an equation as long as you do the same thing to both sides of the equation. So, when we say "divide by 2", we mean "divide both sides of the equation by 2." Likewise, "subtract L" means "subtract L from both sides of the equation."
