Answer: A rhombus has order of rotational symmetry of 2
Step-by-step explanation:
We know that a geometric figure has rotational symmetry if it maps onto itself under rotation about an angle at its center.
The order of rotational symmetry is the number of times the geometric figure maps onto itself during a rotation of 360°.
[ At 180° and 360° it maps onto itself]
A rhombus maps onto itself two times during a rotation of 360°
Hence, A rhombus has order of rotational symmetry of 2.
2 / 4 = 1 / 2 = 9 / 18 ;
2 / 9 = 4 / 18 ;
9 > 4 ;
9 / 18 > 4 / 18 ;
Then, 2 / 4 > 2 / 9 .
b. Total fixed cost are $49885
<h3>What is fixed cost of product ?</h3>
Sometimes production of a product may increase or decrease, but the cost which do not change with the change of output is called fixed cost of the product.
<h3>What is the total fixed cost ?</h3>
Highest monthly total cost = $83800
Highest monthly production units = 3500 desks
Lowest monthly total cost = $61900
Lowset monthly production units = 1240 desks
So, variable cost per unit = (Highest cost-lower cost)/(highest production units-lowest production units)
= ($83800-$61900)/(3500-1240)
= $21900/2260
= $9.7
∴ Total fixed costs=Highest monthly total cost-(highest production units×variable cost per unit)
= $83800-(3500×$9.7)
= $83800-$33950
= $49850
Nearest value is $49885, whch is the correct one.
