Which of the following relations is a function?
a. (11, 5), (3, -8), (7, 0), (11, -6)
b. (0, 11), (-8, 3), (0, 7), (-8, -6)
c. (5, 11), (-8, 3), (0, 7), (0, -6)
d. (5, 11), (-8, 3), (0, 7), (-6, 11)

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.

step-by-step explanation:

you multiply .02 by 30 and get .6.

and then you multiply 5.00 by 30 and get 150.
