Answer:
4sqrt(2) cm
Step-by-step explanation:
a^2 + b^2 = c^2
4^2 + 4^2 = c^2
32 = c^2
sqrt(32) = c
c = 4sqrt(2)
Total is $18.72 so the shopper would need to buy 6 of the 8 packs!!!
Answer:
5.5 7
Step-by-step explanation:
Given the point:
(x, y) ==> (9, 2)
Let's find the new point of the image after a rotation of 90 degrees counterclockwise about the origin.
To find the image of the point after a rotation of 90 degrees counterclockwise, apply the rules of rotation.
After a rotation of 90 degrees counterclockwise, the point (x, y) changes to (-y, x)
Thus, we have the point after the rotation:
(x, y) ==> (-y, x)
(9, 2) ==> (-2, 9)
Therefore, the image of the points after a rotation of 90 degrees counterclockwise is:
(-2, 9)
ANSWER:
(-2, 9)
