Answer:
A: Function <em>f</em>.
Step-by-step explanation:
Let's find the maximum <em>y-</em>value of each function.
Function <em>f </em>is given by:

Remember that the value of cosine is always between -1 and 1. In other words:

Then assuming the greatest value for cosine, we can substitute it for one:

Function <em>g</em> is given by the graph.
Looking at the graph, we can see that the maximum <em>y-</em>value of <em>g</em> is 3.
Finally, function <em>h</em> is given by the table.
Looking at the table, the maximum <em>y-</em>value of <em>h</em> is -2.
Therefore, function <em>f</em> has the greatest maximum <em>y-</em>value.
You are correct. The answer is x=55.
I had this same question before on a test and got it right! good luck!
Answer:
B. 8
Step-by-step explanation:
Given the equation,
,
where,
s = shoe size,
f = foot length,
To determine the shoe size of a man that has a foot length (f) of 9 in, substitute f = 9 into the equation.
(substitution)



His shoe size is approximately 8 inches
