Can you also explain how you got the answers to this

Hope this helps :)

Okay so first just keep in mind the trig formulas

Sintheta= perpendicular/hypotenuse

Costheta=base/hypotenuse

Tantheta= perpendicular/base

Just remember it by " some people have curly brown hair through proper brushing"

And the Pythagorean Theorem

Perpendicular^2+Base^2=Hypotenuse^2

Okay so now our base length is x and perpendicular length is y and hypotenuse is  

for the first three just add the information above in the answer

a)

b)

c)

For the last three, I personally havent done them properly yet but you just reverse the formula if that makes sense

Csctheta=hypotenuse/perpendicular

Sectheta=hypotenuse/base

Cottheta=base/perpendicular

so just add the values we have for base, perpendicular and hypotenuse to these formulas now

d)

e)

f)

dude   i don't even know. i've been trying for hours.

step-by-step explanation:

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
