An iceberg weighs 450,000 pounds. If it loses 0.2% of its weight in a day, what is its new weight at the end of the day?
2 answers:
Answer: The answer is 449100 pounds.
Step-by-step explanation: Given that the weight of an iceberg is 450,000 pounds. It looses 0.2% of weight everyday. We are to find the new weight of the iceberg at the end of the day.
Weight lost by the iceberg in one day will be
Therefore, the new weight of the iceberg at the end of the day will be
Thus, the answer is 449100 pounds.

Equation B is written in vertex form, which means you can read the vertex (extreme value) from the numbers in the equation.
Vertex form is
y = a(x -h)² + k
where the vertex (extreme point) is (h, k). Whether that is a maximum or a minimum depends on the sign of "a". When "a" is negative, the graph is a parabola that opens downward, so the vertex is a maximum.
Equation B reveals its extreme value without needing to be altered.
The extreme value of this equation is a maximum at the point (2, 5).
