Answer:
A'(1, 0 ), B'(1, 2 ), C'(3, - 2)
Step-by-step explanation:
using the rule, add 3 to the x-coordinate and subtract 2 from the y- coordinate of the original points.
A' = (- 2 + 3, 2 - 2 ) = A'(1, 0 )
B' = (- 2 + 3, 4 - 2 ) = B'(1, 2 )
C' = (0 + 3, 0 - 2 ) = C'(3, - 2 )
27.5 is your mean.
To get this, add the figures together and divide by the number of terms.
Look at the picture.
We need a hypotenuse length.
Use Pythagorean theorem:
We have
Substitute:
For the sine we have:
Answer: B
There are two types of crust, continental and oceanic, which differ in their composition and thickness.
I don't know too much about plate tectonics but if Im wrong you can report this and get your points back.
