-12.5%
2/1.5 =0.125 move the decimal and it become 12.5 but because it’s decreasing it is -12.5%
Answer:
Step-by-step explanation:
I'm going to go way out on a limb here and say that you are probably looking for the equation that goes along with that information. If not, you'll learn something anyway!
The equation that we want to fill in is this one:
where h and k are the coordinates of the vertex and p is the distance from the vertex to either the focus or the directrix (since the vertex is directly between the 2). If our vertex is at the origin (0, 0) and the focus is at (-2, 0), first and foremost we need to decide what kind of parabola this is. Remember that a parabola wraps itself around the focus. So our parabola opens to the left (that means that in the end, the equation will be negative, but we'll get there in time). Now we need to determine p, since that's the only "mystery" and everything else was given to us.
p = 2. Filling in the equation:
which simplifies to
and now we solve it for x:
Answer:
they spend the time for swimming is 11/4 ✖ 2 =22/4
that's means in hours =5 hours 30 minutes
With
the singular ODE can be written as
The first term of the second series admits the indicial equation. When
, we have
Factoring reveals two distinct roots at
(in your case, swap
and
before submitting).
Next, shift the index of the first sum so that it starts at
by replacing
, then consolidate the sums to get
Setting
, we then have this as
However I don't see the connection to the given answer... It seems some information is missing, specifically about how the coefficients
are related.
