If the letter z's are distinctly different, there are P(5,5) arrangements. That is
If the z's are interchangeable, the number of different arrangements is given by
Answer:
726
Step-by-step explanation:
Hello!
We can look at each answer choice to verify whether it has a restricted domain or not:
A.
This is a function similar to a cubic root function. Its domain is (-∞, ∞), so it has no restriction.
B.
This is a square root function. This graph only consists of x-values in the interval (3, ∞) because you cannot take the square root of a negative number. This function has a restricted domain.
C.
This is a cubic function, so it has an interval of (-∞, ∞)
D.
This is a quadratic function, which has no domain restriction.
Therefore, the correct answer is B.
Hello :
<span>f (z+5) = (z+5) -1 = z+4</span>
Y = 1/2x + 6
slope here is 1/2. A parallel line will have the same slope.
y = mx + b
slope(m) = 1/2
(0,-2)...x = 0 and y = -2
now sub and find b, the y int
-2 = 1/2(0) + b
-2 = b
so ur parallel equation is : y = 1/2x - 2
