Answer:
The volume is changing at a rate given by:
Step-by-step explanation:
Let's recall the formula for the volume of acone, since it is the rate of the cone changing what we need to answer:
Volume of cone =
where B is the area of the base (a circle of radius R) which equals =
and where H stands for the cone's height.
We apply the derivative over time operator () on both sides of the volume equation, making sure that we apply the rule for the derivative of a product:
Answer:
The average speed of the 747 was of 600 miles per hour.
Step-by-step explanation:
A small airplane flies 750 miles with an average speed of 250 miles per hour.
Velocity is distance divided by time, and here, we find the time of the small airplane. So
1.75 hours after the plane leaves, a Boeing 747 leaves from the same point. Both planes arrive at the same time;
This means that it traveled 750 miles in 3 - 1.75 = 1.25 hours.
What was the average speed of the 747?
The average speed of the 747 was of 600 miles per hour.
