Which shape does not have a rotational symmetry? A) trapezoid
B) regular pentagon
C) circle
D) square

Trapezoid

Step-by-step explanation: Only a 360 rotation will make the shape appear the same again.

A: trapezoid

Step-by-step explanation:

The answer is a trapezoid because it is not even symmetric.

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
