Which is the equation of a parabola with Vertex (0, 0) and directrix y = 4?
1 answer:
We know that
<span>Vertex (0, 0) and directrix y = 4
is a vertical parabola------> open down (directrix above the vertex)
the equation is of the form
(y-k)=4p(x-h)</span>²--------> y=4p*x²-------> vertex (0,0)
y=4
y=h-p-----> y=-p
p=-4
the equation of the parabola is
y=-16x²
the answer is y=-16x² see the attached figure

Answer:
46
Step-by-step explanation:
Lap 1 had an interval of -4 seconds which is solved by (41-45)
Lap 2 had an interval of 46 seconds which is solved by (46-45)
The formula here is Measured Value subtracted by Expected Value
Answer:
The answer is -5.
Step-by-step explanation:
As you look at the first 3 terms, all have the common difference of 4. So the next term after -1 is :
19 - 4 = 15
15 - 4 = 11
11 - 4 = 7
7 - 4 = 3
3 - 4 = - 1
- 1 - 4 = - 5
Answer:
30.80
Step-by-step explanation:
We can use a ratio to solve
4 tickets 7 tickets
------------------- = ----------------
17.60 dollars x dollars
Using cross products
4x = 17.60 * 7
4x =123.2
Divide each side by 4
4x/4 = 123.2/4
x=30.8
