The equation x = -7y^2 describes a parabola. Which way does the parabola
open?

Container A and container B have leaks. Container A has 800 ml of water, and is

leaking 6 ml per minute. Container B has 1000 ml, and is leaking 10 ml per minute.

How many minutes will it take for the two containers to have the same amount of

water?

**Write an equation to represent the situation (first blank). Use the variable m, for

minutes.

**Then solve for m (second blank).

**Finally, use your solution to determine the water level at that time (third blank).

The equation

can represent this situation. It will take

minutes for the two containers to have the same amount of water. At this time,

both containers will have ml left.

1.Read the passage given below.
I have found that nothing in life is worthwhile unless you take risks. Nothing.
Nelson Mandela said: “There is no passion to be found playing small, in settling
for a life that is less than the one you are capable of living.”
I am sure your experiences in school… in applying to college… in picking your
major…in doing what you want to do with life, people have told you to make
sure you’ve something to “fall back on”.
But if I am going to fall, I don’t want to fall back on anything, except my faith.
I want to fall forward. At least I figure that way I will see what I am about to hit.
Thomas Edison conducted 1,000 failed experiments. Did you know that? I
didn’t either, because 1,001 was the light bulb.
Fall forward.
Every failed experiment is one step closer to success. You have got to take risks.
And I am sure you’ve probably heard that before. But I want to talk about why
it is so important.
You will fail at some point in life. Accept it. You will lose. You will embarrass
yourself. There is no doubt about it. That’s not a traditional message for a
graduation ceremony.
But, hey, I am telling you- embrace it. Because it is inevitable.
And I should know; in the acting business you fail all the time.
Early in my career, I auditioned for a part in a Broadway musical. A perfect role
for me, I thought- except for the fact that I can’t sing. So, I start to sing and
they are not saying anything. I think I must be getting better, so I start getting
into it. The director cuts me off saying I will be hearing from him.
I assumed I didn’t get the job.
But the next part of the audition, the acting part, he called me back, though I
didn’t get that too.
But here’s the thing. I didn’t quit. I didn’t fall back.
I walked out of there to prepare for the next audition, and the next audition,
and the next one. I prayed and I prayed, but I continued to fail, and failed and
failed.
But it didn’t matter because if you try long enough you’ll catch your break.
And I did catch a break.
