Answer:
(1, - 8 )
Step-by-step explanation:
Given that P'( - 6, - 4 ) is the image of P(- 2, 3 )
Then the rule is (x, y ) → (x - 4, y - 7 )
Thus
A(5, - 1 ) → A'(5 - 4, - 1 - 7 ) → A'(1, - 8 )
Answer
9 4 -7 -4
Step-by-step explanation:
Answer: N=15
Step-by-step explanation: This is because (4n-18) when solved needs to equal 42. So when solving this you would change the equation to 42=4n-18 and then you need to isolate n. In order to do that you do the opposite so your equation becomes 42+18=4n or (60)=4n. And then you divide 60/4 and get n by itself. Therefore N=15.
Answer: Y and Y'' are congruent after the translation, but not after the dilation.
Step-by-step explanation:
We know that we generally prefer rigid transformations if want to create congruent images.
There are three basic kinds of rigid transformations:
1) rotation 2) reflection 3) translation
So, they all create congruent images.
But a dilation does not create congruent images because it creates an image of similar same shape as the original but not the same size.
Given : Triangle XYZ is translated and then dilated by a scale factor of 4 centered at the origin.
Then, the correct option is "Y and Y'' are congruent after the translation, but not after the dilation."
Answer:
≈ 70.4 cm
Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = 2πr ( r is the radius ) , thus
C = 2 × 3.142 × 11.2 ≈ 70.4 ( to 1 dec. place )
