6^2 = 36
9/3=3
36 - 3 = 33
Answer is D 33
60 minutes per hour
1 1/2 hours = 60 x 1.5 = 90 minutes
90-25 = 65 minutes more
Answer:
In vertex form the equation is
In standard form the equation is
Step-by-step explanation:
The equation of the directrix tells us that this is an x-squared parabola. Because the directrix is above the vertex, the parabola will open downward. The vertex form of this equation is:
where p is the number of units between the directrix and the vertex. The number of units here is .5 or 1/2. Filling in the coordinates of the vertex and the p value of 1/2:
Simplifying we have:
Divide both sides by 2 to get:
Add 2 to both sides to get the final vertex form:
If you want that in standard form, you first need to expand the squared term to get:
Order of operations tells us that we have to distribute in the -1/2 first to get:
which simplifies to the standard form:
I believe it’s C hope this helps:)
