Ik no ones gonna help but The points A(-3,5), B(4,7), and C(1,-6) are vertices of a triangle. That triangle will undergo transformations. Complete the worksheet.
1. The point (-2,-5) will be the center of rotation. What is the horizontal direction and distance of center of rotation to point A?
2. The point (-2,-5) will be the center of rotation. What is the vertical direction and distance of center of rotation to point A?
3. Rotate the answers to numbers 1 and 2 90° clockwise.
4. Use the answer to number 3 and the center of rotation to find the coordinates of point A'.
5. Repeat number 1 with coordinates for point B and the same center of rotation.
6. Repeat number 2 with coordinates for point B and the same center of rotation.
7. Repeat number 3 with the answers from numbers 5 and 6.
8. Use the answer to number 7 and the center of rotation to find the coordinates of point B'.
9. Repeat number 1 with coordinates for point C and the same center of rotation.
10. Repeat number 2 with coordinates for point C and the same center of rotation.
11. Repeat number 3 with the answers from numbers 9 and 10.
12. Use the answer to number 11 and the center of rotation to find the coordinates of point C'.

Congratulations! Points A',B', and C' represent the vertices of image of rotated ∆ABC.

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 ☺

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
