Answer:
A≈149.84
Step-by-step explanation:
A=a2+2aa2
4+h2=62+2·6·62
4+92≈149.842
We are trying to find the average speed of the plane, which is mph, or
. Using proportions, we can find the average speed of the plane in mph:

- Use the information from the problem to create a proportion. Remember that we are looking for mph, so we will call that
.

- Multiply the entire equation by


- Divide both sides of the equation by
to clear both sides of the mile unit
The average speed of the plane is 300 mph.

Never bwa hahaha JK try d
Step-by-step explanation:
The number of potential customers that the company has reached is 10,000 e--mail addresses.
<h3>What is a word problem in mathematics?</h3>
A word problem is a real-life problem and it can be approached with the use of a mathematical model, interpretation into variables, and arithmetic operations usage.
Given that:
- A company buys three mailing lists with 2500, 3500, and 4000 addresses respectively.
The number of potential customers that the company has reached is:
= 2500 3500 + 4000 e--mail addresses.
= 10,000 e--mail addresses.

The area of the region which is inside the polar curve r = 5 sinθ but outside r = 4 will be 3.75 square units.
<h3>What is an area bounded by the curve?</h3>
When the two curves intersect then they bound the region is known as the area bounded by the curve.
The area of the region which is inside the polar curve r = 5 sinθ but outside r = 4 will be
Then the intersection point will be given as

Then by the integration, we have

On solving, we have

Thus, the area of the region is 3.75 square units.
