15b is the answer to this question hope this was helpful
This is a proportion problem
Info needed: there is 36 inches in a yard
1/36= x/18
Cross multiply and divide
18 x 1= 18
18 divided by 36= .5 or 1/2
Answer is 1/2
You could have also known that 18 inches was half of 36 inches. Which 36 inches equals one yard
Pretty sure it would be 21x^2+16x+17y
The domain (input values) of the cosine function is all negative and positive angle measures.
Let the function be f(x) = cos(x)
The domain of cos(x) is -∞ < x < ∞
The range is -1 ≤ f(x) ≤ 1
Hence, domain of cos(x) is all (+) and (-) angle measures.
Same goes with sine function as well
For function f(x) = sin(x)
The domain is -∞ < x < ∞ and range -1 ≤ f(x) ≤ 1
However for f(x) = tan(x) the same is not applicable.
