Answer:

See below

Step-by-step explanation:

a) The vertex is (0,2) so the standard form equation is (x-0)^2=4p(y-2). Since p=1/(4a) and a=1/8, then p=1/(4(1/8))=1/(1/2)=2. This makes the equation now x^2=8(y-2). Given the focus point for a vertical parabola is (h,k+p) then the focus point is (0,2+2) which is (0,4)

b) They are both 4 units away

c) I can't solve

d) I can't solve

Hey! I'v been struggling with this question lately. Can someone just lend me a hand?
Dominik [7]
So, this problem is asking us to find the value of our variable u. 

How can you do this? By isolating the variable, or having only it on one side of the equals sign. 

Here's the step by step approach. It's just simple algebra and reverse order of operation (which is what you should do whenever you are solving for a variable).

\frac{u+88}{11} = 17

Multiply both sides by 11 to get rid of the 11 denominator.
u + 88 = 187

Then, subtract both sides by 88 to get u by itself.
u = 99

Therefore, u is equal to 99.

Advocard [28]

Answer:

492.99

Step-by-step explanation: x = amount invested at 12%

y = amount invested at 9%

---

x + y = 20287

0.12x = 0.09y + 492.99

---

put the system of linear equations into standard form

---

x + y = 20287

0.12x - 0.09y = 492.99
