Airbus is a major manufacturer of aircraft in europe. each of their a330 planes costs around 40 million dollars and airbus' revenue (money coming in) can be modeled as a function of the number of aircraft it sells. which of the following best describes the domain of this function? a. integers b. all real numbers c. rational numbers d. positive integers

B, D, OR C

Step-by-step explanation:

B. this is because it will have whole numbers.

C. this is because it will be a decimal

D. this is because the number would be positive.

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).
