You don't need to have a scientific calculator to do such trivial addition.
1/2 of the side length p= 1/2 x 4 =2
centre angle=360/6=60 degrees
The APOTHEM bisects or divides the centre angle into two equal angles
1/2 of the centre angle=60/2=30 degrees
tan 30 degrees = 2/APOTHEM
APOTHEM=2/tan 30= 3.46 cm
The APOTHEM is the perpendicular height of the equilateral triangle given in the diagram.
Area of the equilateral triangle
=1/2 x 4 x 3.46
=6.93 cm^2
Area of the regular hexagon= 6 x area of the equilateral triangle= 6 x 6.93 =41.6 cm^2
Hope this helps!
Y- y1 = m (x-x1)
y+1 = 4(x+3)
y+1=4x+12
y=4x+11
For the first equation
y = x + 4
the slope is 1
the y-intercept is 4
so your first point on the graph will be at (0, 4)
because x is greater than or equal to -4, but less than 3, you need to plug these numbers in to the equation y = x + 4 to get y
x: -4, -3, -2, -1, 0, 1, 2
y: 0, 1, 2, 3, 4, 5, 6
then you just plug those into the graph, so you start with (-4, 0), then (-3, 1), etc
for the other equation, do the same thing
y = 2x - 1
slope is 2
y-intercept is -1
so you begin at (0, -1)
x: 3, 4, 5
y: 5, 7, 9
hope this makes sense
