Answer:
The equation 
represents the equation of the parabola with focus (-3, 3) and directrix y = 7.
Step-by-step explanation:
To find the equation of the parabola with focus (-3, 3) and directrix y = 7. We start by assuming a general point on the parabola (x, y).
Using the distance formula 
, we find that the distance between (x, y) is
and the distance between (x, y) and the directrix y = 7 is
.
On the parabola, these distances are equal so, we solve for y:
2+2=2x+2
-2 to both sides
2=2x
Divide 2
X=1
Answer:
A. 3:30.
Step-by-step explanation:
180 is 90+90 so that would put it in 3:30.
Answer:
Step-by-step explanation:
<em>Replace it with y</em>
<em>Exchange the values of x and y</em>
<em>Solve for y</em>
<em>Subtracting 1 from both sides</em>
<em>Dividing both sides by 2</em>
<em>Replace it by </em>
So,
You need to know the base to answer this. but if you want i will explain it divide 62.4 by 2 which is 31.2
the you divide 31.2 by what ever the base is and that is your height
