Which figure has the same order of rotational symmetry as a rectangle? isosceles trapezoid regular octagon square rhombus

- Rhombus has the same order of rotational symmetry as a rectangle.

Explanation:-

The order of rotational symmetry of rectangle= 2

⇒180° and 360° rotations will map it onto itself.

The order of rotational symmetry of isosceles trapezoid=1

The order of rotational symmetry of regular octagon=8

The order of rotational symmetry of square=4

The order of rotational symmetry of rhombus=2

Thus, rhombus has the same order of rotational symmetry as a rectangle.

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)
