Answer:
They are not commutative, because f(g(x)) and g(f(x) are not equal.
Step-by-step explanation:
In order for the composition of the functions to be commutative, we must have ...
f(g(x)) ≡ g(f(x))
for all values of x.
Here, we have f(g(x)) = 1 and g(f(x)) = 2. f(g(x)) and g(f(x)) are not equal, so the composition of the functions is not commutative.
It’s 9, add 9 to 33 to get 42, add 9 to 42 to get 51, and add 9 to 51 to get 60. It works
Answer: Angle B measures 30 degrees.
Step-by-step explanation: First of all, angles A and B are complimentary, which means they both add up to 90. Also the cosine of angle A has been given as 0.5
The value in degrees, of an angle whose cosine is 0.5000 is equal to 60 degrees (this can be verified with a table of values, or by checking the second function Cosine of a calculator).
Where angle A has been determined to be 60 degrees and angles A and B are complimentary, angle B is derived as follows;
Angle A + Angle B = 90 {Complimentary angles equal 90}
60 + Angle B = 90
Subtract 60 from both sides of the equation
Angle B = 30 degrees

The ratio of outputs is: 4:(1/4) = 4:(1/4) = 4 ÷ (1/4) = 4/1 * 4/1 = 16/1 = 16:1 = 16.
From the answer choices given, "2⁴ = 16" ; since: " 2*2*2*2 = 16 ";
which corresponds to:
