Answer:
Cartesian Coordinate System
• Also called
rectangular coordinate
system
• x- and y- axes intersect
at the origin
• Points are labeled (x,y)
Polar Coordinate System
– Origin and reference
line are noted
– Point is distance r from
the origin in the
direction of angle θ,
ccw from reference
line
– Points are labeled (r,θ)
Cartesian to Polar Coordinates
• r is the hypotenuse and θ
an angle
θ must be ccw from
positive x axis for these
equations to be vali
Step-by-step explanation:
Answer: C) 78 in2
Step-by-step explanation:
The polygon is divided into two trapezoids with equal measurements.
Area of a trapezoid:
1
2
(b1 + b2)h
Since the area of the hexagon equals the area of two trapezoids with equal measurements, do not multiply by 1/2.
(b1 + b2)h
(10 + 16)3
26(3)
78 in2
Answer:
a.(3x+2)(5x+8)
Step-by-step explanation:
area of rectangle formula- length times width
so l= 3x+2 and w= 5x+8
Answer:
$3.75
Step-by-step explanation:
Candles = C
36C = $27.00
Divide both sides of the equation by 36
C = 0.75
The cost per candle is $0.75
Multiply by 5 to get the cost of 5 candles
$3.75
