EXAMPLE 2 Interpret Parts of an Expression The expression 8x + 12.5y + 6 gives the total cost in dollars of ordering x T-shirts and
y caps from a Web site. The cost includes a fee for shipping that is the same no matter
how many shirts or caps you order.
a. USE STRUCTURE What does the coefficient 8 represent in the expression? What
does the term 8x represent? Explain.
b. USE STRUCTURE What does the coefficient 12.5 represent in the expression?
What does the term 12.5y represent? Explain

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
