Answer:
Step-by-step explanation:
The directrix y=-6 is parallel to the x axes, so parabola has equation of the form
where 
is the vertex of parabola and p is parabola's parameter.
By the definition, 
is the distance from the vertex to the directrix, so
Hence, the equation of parabola is
See attached diagram for the graph of parabola and its directrix.
In vertex form this equation is
Answer:
Step-by-step explanation:
The general equation for a circle is
Where a and b are the x and y values of the centre. So comparing to your equation you can see that a is 2/3 and b is 0
Answer:
1 1/5
Step-by-step explanation:
To get the answer you pratically change 12/10 into a mixed number.
So you say 12 divided by 10 which is 1 leaving a remainder of 2
We write it like this:
1 2/10
We can then reduce it to its simpliest form and it becomes 1 1/5

Answer:
The first one cannot be simplified
reason: usually when simplifying an expression you combine like terms but in the given expression there are no like terms
An example of like terms would be 6a and 9a
Essentially what i am saying is that the variables have to be the same in order for them to be combined
The second one is 36r
This is the answer because they tried to combine like terms that aren't similar
r and f are not the same variable therefore they cannot be combined
Hope this helps :)
Answer:
The answer is d because 0.04 is the same as 4% and 3.5 < 0.04
