The answer to this is going to be 9 and 16.
Since the sine and cosine ratios involve dividing a leg (one of the shorter two sides) by the hypotenuse, the values will never be more than 1, because (some number) / (a bigger number) from a right triangle is always going to be smaller than 1.
Step-by-step explanation:

Where Z is set of integer.

is a number used to express shorter equation; it is a number that says how many
times you are going to multiply the base number.

Exponents have several laws, here are
some:
=> x^1 = x
=> x^0 = 1
=> x^-1 = 1/x
=> x^m x^n = X^m+n
=> x^m/x^n = x^m-n
And since we were asked to write an
expression with a negative exponent that has a value between 0 and ½
=> 2^ -2 = ½

Answer:
k = 5
Step-by-step explanation:
k/2+1/2=3
Multiply each side by 2 to get rid of fractions
2(k/2+1/2)=3*2
k+1 = 6
Subtract 1 from each side to isolate k
k+1-1 = 6-1
k = 5
