The Test

There will only be about 10 questions total on this test.  There will be all the ones listed and a few more.  Take your time and do it right.

More Test Questions...Again

The function y= -64(x - 3)2 + 400 models a store's profits in dollars on a certain food item where

x is the price of the item. What should the store charge for the item to maximize the

profit? What is the maximum possible profit that can be earned according to the model?

Use the table of values for the quadratic function below to determine between which two

x values f(x) will have a zero.

x

2 5 8 11 14

f(x) -2 -5 10 43 94

Find the vertex for the function:

y= x2 + 4x - 7

The path of a toy rocket launched from an observation tower is modeled by the equation:

h(t) = -16t2 + 48t + 64 where t is time in seconds and

h is height in feet. In how many seconds will the toy rocket first reach 90 feet?

Unit 6 Test Questions

Boys won both games today.  We play in the Championship tomorrow vs Panhandle at 4:00.  Since we got in late tonight, I am only going to post one question.  Feel free to comment or ask questions.

Greg is looking at the graph of a parabola. Its vertex is (2, -144), it intersects the

x-axis at -4 and 8, and it intersects the  y-axis at -128.

What are the roots of the equation he has graphed?

For Educational Purposes?

Why do I keep doing this?  I will attempt to post stuff for Algebra II kids.  I really need to use this blog or just kill it.

The Kody Talk

I am very blessed to have a pretty smart kid.  He still can be a pain in the rear, especially to his brothers.  He was refusing to share something with Aaron today.  I got to talking with him and he told me that he didn't want to share.  I told him that sometimes we have to do what's right, even if it's something we don't want to do.  There are lots of times I don't want to do right, I want to do what I want to do.  That's just how humanity is.  Thank you, Jesus, for grace.  Thank you for breaking the bonds of sin so we can even choose what's right over what we want.  How often do we forfeit what is right for what is convenient or fun?

Apologies

If your car pic didn't get posted, I'm sorry.  There were a lot, and I really didn't want to put more of them.

Stay tuned for pictures from our balloon car experiment.

Update of the week

The boys and I went on an expedition to the Metroplex earlier in the week. We had a blast. We watch G-Force and both boys really liked it. We saw the Rangers beat the Tigers Tuesday night and went to the Fort Worth Zoo and had a great time. Lots of fun. I learned a lot about solo parenting and I'm not really good at it, but I got better really fast. I look forward to our next adventure.

Football begins tomorrow, so I can officially say goodbye to my family for an extended period of time. Goodbye family, see you in December.

TWITTER

OK. I conformed. I know I'm not supposed to, but I conformed. I have a twitter. twitter.com/coachcates I wish I had a data plan so I could break some sweet news stories from anywhere, but news can wait until I get in a Wifi area.

Look, it's a blog post!

I ought to post a little more often. I think I will when school starts. I am uploading a few football films to YouTube, so y'all should go check that out. I have a change is coaching assignment this year. I'm doing freshman football and some form of HS basketball and baseball in the spring instead of track. I hate not coaching track, but have really always liked baseball and I'm really looking forward to it.

In other news, Sunni has a doctors appointment on the 17th. Should be fun.

Three in a Row

Maybe a record, I don't know. Three days in a row with a blog post is pretty sweet though, huh? Well, sweet for y'all, my fans. Both of y'all. Today was a cold day.

McDonalds has free coffee drink for the next couple of weeks to promote the new McCafe. It's gonna be like Starbucks, except for poor people who eat at McDonalds. I will never understand how you can buy a box of Swiss Miss for $1.50, but you pay $2.39 for a "gourmet" hot chocolate at the McCafe or similar setting. Oh, and another thing. There is no longer a double cheeseburger on the dollar menu. Yeah, the double cheeseburger is $1.19. That is crap, people. They do have a new "McDouble" on the dollar menu which is just like the DCB minus one piece of cheese. They decided to tell me this after I placed my order and was taken aback by the higher-than-normal total. The single piece of cheese on the McDouble is definitely worth the savings. I don't think a piece of cheese should cost $.19

So, Sunni and I took Kody and Aaron out in the stroller to look at some Christmas lights. That was fun. It was pretty cold outside, but they had their hoods, so it was all good...in the hood...HA! Kody decided to argue whether the sun was asleep or not. He clearly identified the moon was awake. But then he also argued the sun was awake, because the moon was awake, and he kept pointing to the moon and saying, look, the sun is awake. I mean, technically, he is right, the sun never sleeps and the moon has light because of the sun, but I seriously doubt he knows anything about that and can argue that point from that level. I am thinking he just likes to argue.

Well then, I guess that just about wraps it up. Tomorrow is Friday. Yeehaw.
