Answer:
A value that does not change
Step-by-step explanation:
eg: -5 is the constant term in p(x) = 2x^3 - 4x^2 +9x -5
24% = 24/100 = 12/50 = 6/25
24% is 6/25 fraction of world's energy.
Honestly I really don’t know if I am right but I think it is b
The left side can be written as a square. We can take the square root, then subtract 1.
... (x +1)² = 17
... x +1 = ±√17
... x = -1 ±√17
We have been given two expressions . We are asked to find the value of each.
To find 9P9, we will use permutations formula.
, where
P = Number of permutations,
n = The total number of objects in the set,
r = Number of objects being chosen from the set.
Using
To find 9C9, we will use combinations formula.
, where
C = Number of combinations,
n = The total number of objects in the set,
r = Number of objects being chosen from the set.
Using
Cancelling out , we will get:
The answers differ because order. With permutations we care about the order of the elements, while with combinations we don't.
