Answer:
141.3 inches.
Step-by-step explanation:
45 multiplied by 3.14 (or π) is 141.3. Good luck!
Ans: Option A
Explanation:Let's solve it smartly!
Given expression:
![x^{2} + bx +c](https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20%2B%20bx%20%2Bc)
--- (A)
Factors: (x+p)(x+q)
Condition: c<0
Now let us expand (x+p)(x+q):
=>
![x^{2} + (p+q)x + pq](https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20%2B%20%28p%2Bq%29x%20%2B%20pq)
--- (B)
By comparing (B) with (A), we can say that:
pq = c --- (C)
Now, as the condition says,
c<0, it means either p or q is negative. Both cannot be positive or both cannot be negative.
1) If p>0, q>0, it means c>0 since (+p)(+q) = (+c)(according to equation (C)). Condition is not met.
Hence, option B and D are wrong.
2) If p<0, q<0 it means c>=0 since (-p)(-q) = (+c)(according to equation (C)). Condition is not met.
Hence option C is out as well.
We are left with Option A:
p<0, q>0 it means c<0 since (-p)(+q) = (-c)(according to equation (C)). Condition is MET!
Hence,
Ans: Option A: p= -3, q= 7

The atom's place on the table is determined solely by its number of protons
- A periodic table is a table containing different elements and arranged across the periods and groups of the table.
- The elements in a periodic table are numbered and arranged based on their atomic number.
Since the atomic number is equal to the number of protons an element contains, hence we can conclude that <u>the atom's place on the table is determined solely by its </u><u>number of protons</u>
