The focus of a parabola is (-3,-5) The directrix of the parabola is y=2
cricket20 [7]

Check the picture below.

so the focus point is there, and the directrix is above it, meaning is a vertical parabola and is opening downwards, since the parabola opens up towards the focus.

now, the vertex is half-way between those two guys, at a "p" distance from either one, if we move over the y-axis from -5 to +2, we have 7 units, half-way is 3.5 units, and that puts us at -1.5 or -1½, as you see in the picture, so the vertex is then at (-3 , -1½).

so the distance from the vertex to the focus point  is then 3½ units, however since the parabola is opening downwards, "p" is negative, thus "p = 3½".

\bf \textit{parabola vertex form with focus point distance} \\\\ \begin{array}{llll} 4p(x- h)=(y- k)^2 \\\\ \stackrel{\textit{using this one}}{4p(y- k)=(x- h)^2} \end{array} \qquad \begin{array}{llll} vertex\ ( h, k)\\\\ p=\textit{distance from vertex to }\\ \qquad \textit{ focus or directrix} \end{array} \\\\[-0.35em] \rule{34em}{0.25pt}

\bf \begin{cases} h=-3\\ k=-\frac{3}{2}\\[0.7em] p=-\frac{7}{2} \end{cases}\implies 4\left( -\cfrac{7}{2} \right)\left[ y-\left(-\cfrac{3}{2} \right) \right]=\left[ x-\left( -3 \right) \right]^2 \\\\\\ -14\left( y+\cfrac{3}{2} \right)=(x+3)^2\implies y+\cfrac{3}{2} =-\cfrac{(x+3)^2}{14} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill y=-\cfrac{1}{14}(x+3)^2-\cfrac{3}{2}~\hfill

Find the 9th term of the geometric sequence 5, -25, 125, ...
Ganezh [65]

9514 1404 393

Answer:

  1,953,125

Step-by-step explanation:

The first term is a1 = 5; the common ratio is r = -25/5 = -5. The generic term is ...

  an = a1×r^(n-1)

  an = 5×(-5)^(n-1)

So, the 9th term is ...

  a9 = 5×(-5)^(9-1) = 1,953,125

Plz help me with this and explain how u got the answer
kolbaska11 [484]
I'm going to set up an equation to find the amount of momey Elisa has, then we can check our answer

e + 2e + 2e + 5 + 2e + 5 · 3 + e + 2e = 69
Simplify:
10e + 30 = 69
Subtract 35 from each side:
10e = 39
Divide by 10 on each side
e = 3.9

We can check our answer by putting the value in the simplified equation.
10 · 3.9 + 30 = 69
Yep! The equation is correct. Now for the answer.

Elisa
3.9
Jacob
7.8
Sandra
12.8
Damian
38.4
Martin
11.7

Hope this helped! If you have anymore questions or don't understand, please comment on my profile or DM me. :)
