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.

Answer:
$863
Step-by-step explanation:
Given: Carla Arslanian is 55 years old. She wants to purchase a $100,000, 10-year term life insurance policy.
To find: What is her annual premium?
Solution: Insurance companies use mathematical calculation and statistics to calculate the number of insurance premiums they charge their clients.
Annual premium = face value x rate $100
Annual premium (for building) = $100,000 ÷ $1000 x 10 = $1000.
The sum of the annual premium is $863.
Hey there!
We know that since the triangle got smaller, it had to have shrunk. The answer will be a fraction, we can eliminate choice A and C.
We can use the x-axis as reference to figure out how much it was dilated.
J went from 8 to 4.
L went from 12 to 6.
K went from 4 to 2.
We know that the dilation was centered around the origin, so, we can assume that these numbers were not influenced by anything other than the dilation.
4 is half of 8, 6 is half of 12, and 2 is half of 4.
The correct answer is 1/2.
I hope this helps!
