1. which type(s) of symmetry does the uppercase letter h have? (1 point)
reflectional symmetry
point symmetry
reflectional and point symmetry
rotational symmetry

2. which type of symmetry is shown by the lowercase letter w? (1 point)
reflectional symmetry
point symmetry.
no symmetry
rotational symmetry

1. Answer;

-Reflectional and point symmetry

Explanation;

-Symmetry is when two or more parts are identical after a flip, slide or turn.

-Point Symmetry is when every part has a matching part: the same distance from the central point, but in the opposite direction. In this case the upper case H. exhibits both point symmetry and also reflectional symmetry.

2. Answer;

-Reflectional symmetry

Explanation;

-Reflection symmetry is a type of symmetry where one half is the reflection of the other half. It occurs when a line is drawn to divide a shape in halves so that each half is a reflection of the other. Lower case w has a reflection symmetry, as one half of it is the reflection of the other half.

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺
