Answer:
f(-5)=-5
f(0.4)=0.4
Step-by-step explanation:
Fill in -5 and 0.4 for x in f(x)
I think it is 4 because it’s how many times it crosses the x axis
Answer:
12 + 4x= (6 x 2) + (2x x 2)
Step-by-step explanation:
this is the pic
Answer:
39.30 
Step-by-step explanation:
The area of the top surface of the wedge is the same as the area of a sector.
Area of a sector = (θ/
)

where: θ is the central angle, and r is the radius.
Given that: central angle =
, radius = 10 centimetre.
Area of the top surface = Area of a sector = (θ/
)

=
x
x 
=
x
x 100
= 39.2857
= 39.30 
The area of the top surface of the wedge is 39.30
