Find the domain of the function.
f(x) = sqrt of x+8 / (x+4)(x-6)

answer options:
a) x is not equal to -8, x is not equal to -4, x is not equal to 6
b) x> 0
c) all real numbers
d) x is greater than or equal to -8, x is not equal to -4, x is not equal to 6

i think the answer is d.

assuming you mean addition: addition and subtraction are reverse operations.

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).
