Answer:
y²=4√2.x
Step-by-step explanation:
The focus is at (0,4) and directrix is y=x or x-y =0, for a parabola P.
The distance between the focus and the directrix of the parabola P is
=
{Since the perpendicular distance of a point (x1, y1) from the straight line ax+by+c =0 is given by }
Let us assume that the equation of the parabola which is congruent with parabola P is y²=4ax
{Since the parabola has vertical directrix}
Hence, the distance between focus and the directrix is 2a = , {Two parabolas are congruent when the distances between their focus and the directrix are same}
⇒ a=√2
Therefore, the equation of the parabola is y²=4√2.x (Answer)
the answer is A
700 x 5 = 3500
30 x 5 = 150
7 x 5 = 35
3500 + 150 +35 = 3685
700 x 200 = 140,000
30 x 200 = 6000
7 x 200 = 1400
140000 + 6000 + 1400 = 147400
5500+100.50x=4597+<span>175.75x
</span>175.75x-100.50x=5500-4597
75.25x= 903
x=903/75.25
x=12

If Manfred hiked 2/7 of a 588 mile trail, then to find how many miles he has hiked all we need to do is multiply the total miles (588) by what fraction of the miles he has traveled (2/7):
588 * 2/7 = 1176 / 7 = 168
Therefore, Manfred hiked 168 miles.
