Their are many different types of atoms in the universe. It can include the proton, neutron, and the electron. Also, the quark is a particle but is not found alot.
Answer:
The volume of the solid = π²
Step-by-step explanation:
As per the given data of the questions,
The diameter of each disk is
D = 2 sin(x) - 2 cos(x)
So its radius is
R = sin(x) - cos(x).
The area of each disk is
![= \pi \times [sin^{2}(x) - 2 sin(x) cos(x) + cos^{2}(x)]](https://tex.z-dn.net/?f=%3D%20%5Cpi%20%5Ctimes%20%5Bsin%5E%7B2%7D%28x%29%20-%202%20sin%28x%29%20cos%28x%29%20%2B%20cos%5E%7B2%7D%28x%29%5D)
![= \pi[1-2sin(x)cos(x)]](https://tex.z-dn.net/?f=%3D%20%5Cpi%5B1-2sin%28x%29cos%28x%29%5D)
![= \pi[1-sin(2x)]](https://tex.z-dn.net/?f=%3D%20%5Cpi%5B1-sin%282x%29%5D)
Now,
Integrate from 
, we get volume:
![V=\int_{\frac{\pi}{4}}^{\frac{5\pi}{4}} \pi[1-sin(2x)]dx](https://tex.z-dn.net/?f=V%3D%5Cint_%7B%5Cfrac%7B%5Cpi%7D%7B4%7D%7D%5E%7B%5Cfrac%7B5%5Cpi%7D%7B4%7D%7D%20%5Cpi%5B1-sin%282x%29%5Ddx)
After integrate without limit we get
![V=\pi[x+\frac{cos2x}{2}]](https://tex.z-dn.net/?f=V%3D%5Cpi%5Bx%2B%5Cfrac%7Bcos2x%7D%7B2%7D%5D)
Now after putting the limit, we get
V = π²
Hence, the required volume of the solid = π²
Jennifer earns $5.50 per hour
Edward earns ($5.50*1.8) $9.90 per hour
Edward earns more per hour
To find out how many hours they'd have to work to make 50$, we would just divide $50 by their hourly wage.
Jennifer=50/5.50=9.09 hours since you cant have 0.09 hours round up
Jennifer=10 hours to make at least $50 dollars
Edward=50/9.90=5.05 hours since you cant have 0.05 hours round up
Edward=6 hours to make at least $50 dollars
**Edit. Since Edward earns 1.8 times what Jennifer earns, that means he earns 180% of what she earns or 80% more. So we can tell that he earns more just by the 1.8.
1.8=180%

Step-by-step explanation:
The question is incomplete..
The given parameters can only solve for the number of hours the battery can last if at full capacity.
Given
25% = 4.5 hours
Required
Determine the brand
First, we need to determine the full capacity (100%)
So, we have:
25% = 4.5 hours
100% = x
Cross Multiply
25% * x = 100% * 4.5 hours
Divide both sides by 25%
x = 4 * 4.5 hours
x = 18 hours
Hence, the battery at full capacity is 18 hours.
So, to answer the question, you need to check the given list of brands.
The brand closest to 18 hours answers the question
