Answer:

Step-by-step explanation:
General equation of a parabola that opens up is
, a>0
So equation becomes
which implies option A and option B can never be true for this parabola.
Also this parabola's vertex lies in 3rd quadrant where coordinates of both x and y will be negative.
So, the equation of parabola will be of the form 
Hence, option 4 that is
is correct.
Answer:
a right triangle
Step-by-step explanation:
because if you rotate your head, then you can see that the top is at a 90 degree angle
The probability would be out of 100,
in this case if it refers to the data from 2009 it would be 39:61
Answer: D (I think)
Step-by-step explanation:
<SUT is a right angle.
I believe <SUW is equal to 152 degrees.
