The three main trig functions are sine (written as sin), cosine (written as cos), and tangent (written as tan).
Sine of an angle = the length of the side opposite (aka across) the angle / the length of the hypotenuse
Cosine of an angle = the length of the side adjacent (aka the side next to which isn't the hypotenuse) to the angle / the length of the hypotenuse
Tangent of an angle = the length of the side opposite of the angle / the length of the side adjacent to the angle.
The acronym to remember this is SOHCAHTOA
SOH | CAH | TOA
SOH means sin(x) = opposite/hypotenuse
CAH means cos(x) = adjacent/hypotenuse
TOA means tan(x)= opposite/adjacent
cosB = length of adjacent side/length of hypotenuse = 7/25
tanB = length of opposite/length of adjacent = 24/7
sinB = length of opposite/length of hypotenuse = 24/25
F(x)=8+2x
f(1/2)=8+2(1/2)
=8+1
=9
Can't graph atm :/
Answer:

Answer:
y= -4+3x
Step-by-step explanation:
Well 125 is 100 + 25. Put those into decimal form, separately, then add them together.
100 --> 1.0
25 --> 0.25
1.0 + 0.25 = 1.25
Change from decimal to fraction form:
1.25 --> 1&1/4
