Step-by-step explanation:
22 + 42 divided by 22
we always to division and multiplication before adding or subtracting, so
(42/22) + 22 = a very lonnggg number = 23.9090909091?????
are you sure the equation is correct?
i can help you
thank you
Refer to the diagram shown below.
The distance, d, from the focus to a point P (x,y) is equal to the distance from the directrix to P.
Therefore
d² = (6 - y)²
= (x + 2)² + y²
That is,
36 - 12y + y² = (x + 2)² + y²
12y = -(x + 2)² + 36
The equation of the parabola is
y = -(1/12)(x + 2)² + 3
It may be written as
-12(y - 3) = (x + 2)²
The leading coefficient -1/12 is negative, therefore the curve opens downward.
Answer:
The equation is (x + 2)² = -12(y - 3).
The curve opens downward.
Answer:
‘Of’ signifies multiplication. So, multiply 1/3 by 15, which gives you 15/3, which is 5.
