Answer:
d. only the first equation is an identity
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is

Here [ a, b ] = [ 1, 3 ]
f(b) = f(3) = - 8 ← from graph point (3, - 8 )
f(a) = f(1) = 0 ← from graph point (1, 0 )
Then
average rate of change =
=
= - 4 → C
Answer:
96pi units²
Step-by-step explanation:
Area of sector = ½ × r² × theta
½ × 16² × (3pi/4)
96pi units²
3x-15=x+3/3
9x-45=x+3
9x-x=3+45
8x=48
x=6
∠ABC=3×6-15=3°
∠DEF=6+3/3=3°
Hope my answer helped u :)
