Answer:
208,827,064,576 user names
Step-by-step explanation:
There are "8" places for each letter of the alphabet.
Since upper and lowercase are same and let's assume repetition is possible, we can say that each "placeholder" can hold 26 letters.
According to counting rule, we have to multiply the number of possibilities in each "place". That would be:
26*26*26*26*26*26*26*26 = 208,827,064,576 user names
There are over 208 billion user names possible(!!!)
Answer:
Total number of edges for resulting solid = 12
Step-by-step explanation:
A wooden block measures 2 inches by 2 inches by 3 inches. A wedge is cut off from each corner of the block by slicing at points that are 1 inch from each corner.
We have to find the number of edges in the resulting solid after we cut the edges as told above.
There are two faces along the height which will become sharpened after we take out the cuts.
So the resulting shape would be like that of a cylinder with its both ends pointed.
So total number of edges = 4 + 4 + 4 = 12
Answer:
x^4 -x^3 -4x^2-3
Step-by-step explanation:
f(x)=x^4−x^2+9
g(x)=x^3+3x^2+12
(f−g)(x)= x^4−x^2+9 - (x^3+3x^2+12)
Distribute the minus sign
(f−g)(x)= x^4−x^2+9 - x^3-3x^2-12
I like to line them up vertically
x^4 −x^2+9
- x^3 -3x^2-12
---------------------------
x^4 -x^3 -4x^2-3
