Answer:
The equation of the parabola with a focus at (4,-7) and a directrix of y=-15 is
Step-by-step explanation:
we need to drive the equation of the parabola with a focus at ( 4, -7) and a directrix of y= -15
From the given focus ( 4, -7) and equation of directrix y = - 15 calculate p
where is is ordinate of focus and y is equation of directrix.
Calculate the vertex (h,k)
vertex (h,k) =(4,-11)
Since, vertex form is :
(positive 4p shows it open upward)
subtract both the sides by 176,
Divide both the sides in above by 16,
Hence, the equation of the parabola with a focus at (4,-7) and a directrix of y=-15 is
19. P(4, -2)
20. P(0, -6)
21. P(-3, -4)
Answer:
see below
Step-by-step explanation:
When you're doing a bunch of these, it is helpful to make a table with reminders as to how they're calculated. That table is shown below.
__
In the attached, we have used ...
r² = x² +y²
√20 = 2√5
√36 = 6
√25 = 5
and 1/(2√5) = √5/10. (The division is outside the radical.)
A: 13%
B: 66%
C: 34%
D: 76%
Standard Deviation: $_________a1
Answer:
