Answer:
8
Step-by-step explanation:
0 = –x^2 + 4x – 2
This is of the form
ax^2 +bx +c
a = -1 b = 4 x = -2
The discriminant is
b^2 -4ac
4^2 - 4(-1)(-2)
16 - 8
8
Answer:
3^x+6x+2
Step-by-step explanation:
if f(x)= -3-5 and g(x)= 4x-2, find (f-g)(x)=3^x+6x+2
Sin = - 4/8
Quadrant IV = only cosine is positive
a = height (4)
b = base ( 8^2-4^2=b^2
b = 6.93 @

c = hypothenuse(8)
cos =

/8
tan = - 4/

sec = 1/cos
1/cos = 1/ (

/8)
sec = 8/

csc = 1/sin
1/sin = 1/(-4/8)
csc = - 2
cot = 1/tan
1/tan = 1/(-4/

)
cot = -

/4
