Evaluate \dfrac{e}{4}+2f-3 4 e +2f−3 when e=12e=12 and f=\dfrac12f= 2 1 .

-406

Step-by-step explanation:

We have the following expression:

In addition we know:

and

If we substitute this in the expresion, we will have:

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).

yes   because as the functions are graphed they eventually will intersect unless otherwise
