Could i get with this ! the coordinates of the vertices of △def are d(2, −1) , e(7, −1) , and f(2, −3) . the coordinates of the vertices of △d′e′f′ are d′(0, −1) , e′(−5, −1) , and f′(0, −3) . what is the sequence of transformations that maps △def to △d′e′f′ ? drag and drop the answers into the boxes to correctly complete the statement. a sequence of transformations that maps △def to △d′e′f′ is a followed by a options:

The coordinates of the vertices of △DEF are D(2, −1) , E(7, −1) , and F(2, −3) .

The coordinates of the vertices of △D′E′F′ are D′(0, −1) , E′(−5, −1) , and F′(0, −3) .

When we reflect over  the y axis, the y  values are  unchanged and the x  values are opposite

so △DEF are D(2, −1) , E(7, −1) , and F(2, −3) , reflection over the y axis will become △D′E′F′ are D'(-2, −1) , E'(-7, −1) , and F'(-2, −3)

Translation 2 units right( means x values move to the right 2 units and y values are unchanged)

△D′E′F′ are D'(-2, −1) , E'(-7, −1) , and F'(-2, −3) > D′(0, −1) , E′(−5, −1) , and F′(0, −3)

1st one: Reflection across the y-axis

2nd one:  Translation 2 units right

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
