Which of the following equations is of a parabola with a vertex at (1, -2)? y = (x - 1)2 - 2 y = (x - 1)2 + 2 y = (x + 1)2 - 2 y = (x + 1)2 + 2

Step-by-step explanation:

Givens

The explicit form of a parabola is

Where is the vertex.

So, we know that . Replacing these values, we have the following expression

Therefore, the right answer is the first choice

1 1/5

step-by-step explanation:

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
