Corrine wrote temperatures in degrees celsius and the equivalent temperatures in degrees fahrenheit. equivalent temperatures celsius –10 5 10 20 fahrenheit 14 41 50 68 which explains how corrine could determine if the temperatures vary directly? compare the equivalent temperatures as a ratio; if the ratios are equivalent, then the temperatures vary directly. draw a graph of the temperatures; if the points form a straight line, then the temperatures vary directly. write an equation that converts one temperature to another; if the temperatures satisfy the equation, then they vary directly. look for a pattern in the table; if the pattern is consistent, then the temperatures vary directly.

it would be 6xy and -16xy.

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).
