Answer:
Check.
Step-by-step explanation:
a. Let such that f(n) = 2n.
Injective:
Let n, m such that f(n)=f(m). Then,
2n = 2m and dividing both sides by 2 we obtain that n=m. Then f is injective.
Surjective:
Let n , so n = 2k for some integer k. Then, f(k) = n and therefore f is surjective.
b. Let such that g(n) = n/2. Then,
g(f(n)) = g(2n) = 2n/2 = n, and for m
f(g(m)) = f(m/2) = 2*m/2 = m.
Therefore, g is the inverse of f.
Answer:
AngleWUT =38°, option 2
Step-by-step explanation:
We have three rays passing through U. A ray is set extend in one direction with one fixed point.
We have UW ray bisecting VUT.As the ray bisects the angle between VUW and WUT would be same .
Given angles are (4x+6)° and (6x-10)°.
As these angles are equal
AngleWUT = (6x – 10)°
and x is 8 so on substituting AngleWUT =38°.
