Answer:
C
Step-by-step explanation:
Under a translation < 2, 3 >
K(- 1, 6 ) → K'(- 1 + 2, 6 + 3 ) → K'(1, 9)
Under a reflection in the y- axis
a point (x, y) → (- x, y), thus
K'(1, 9 ) → K''(- 1, 9) → C
Both
Both because they are each a pund plz rate 5
What? Hey no no no yes what no no yes what yes yes
Yes, it is a function because for each pair, none of the x's are the same
The ball hits the ground when the height h(t) = 0 , so
-16t^2 + 80t = 0
-16t(t - 5) = 0
t- 5 = 0 or -16t^2 = 0 ( here t = 0 which corresponds to when ball is thrown)
t - 5 = 0 gives:-
t = 5 seconds (answer)
