Finite Math

[Governor Megachris%Participant 3584]

I know this is weird to bring up on this forum, and kinda unrelated…but I’m taking Finite Math and I can’t seem to figure ANY of it out. If I pass this class, I get the tuition reimbursed thanks to my job. I’m one assignment in and I’m already feeling stupid. I can’t figure it out for the life of me. Hopefully one of the guys on here knows math or something, because I can’t remember math without writing it all down and looking at the notes…ALWAYS.

The question is:

“A consulting firm, using statistical methods, provided a veterinary clinic with the cost equation

C(x)=0.00048(x-300)^3+228,000
100 [less than or equal to] x [less than or equal to] 1,000

Where C is the cost in dollars for handling x cases per month. The average cost is given by C [with a line above the C](x)=C(x)/x.”

I figured out how to write an equation for it just fine, but then it starts getting into graphing, and I’m totally lost. I use the “give me an example” option, but it’s completely useless. All it does is tell you that they “graphed it.” It doesn’t say HOW to graph it. Not even the textbook is useful here. I’m stressing on the 12th and 13th question of the FIRST assignment and I already have a feeling I’m going to fail again.

I am an engineer and mathemtician tutor. What is the question asking you to find? Is it asking you to find the average cost? take a screen shot and share.

Hopefully that can be read. I’m BARELY understanding any of it, but this part has me the most puzzled. I feel like it seems like it should be rather elementary to figure this stuff out, but graphing is not my specialty. I can plug numbers in and do problems like that in my head, but when it comes to terminologies and all that, it never sticks well in my head for some reason. I’ve never been able to remember any of it, and I’ve now taken math twice and failed. The blue shaded answer is the one I’ve already done right, and I literally just GUESSED the second one because I don’t have a graphing calculator at the moment. I can use one online, but either way, I’m completely lost on how to use it anyway.

I FOUND IT! At last! Good mercy, this was a pain to input, but I finally typed it in correctly into the graphing calculator. It was 800! I’ll update on any other issues…

to minimize the average cost the c bar of x needs to be as close to zero as possible. Your parameters are between 100 and 1000. I used my calculator to find the minimum and got x=800. Try that.

Oh glad to hear it. I didn’t update the post so i didnt realize you solved it. My bad for being late.

No worries. I’m still completely stuck on literally everything else as well. I’m sitting at work 3 hours after my shift just using their Internet to get some homework assignments done. Math really makes me want to jump off a cliff though, honestly. I understand basic math and I can perform a lot of it in my head, but once it starts getting into the extremely advanced stuff like having to use logarithms and all those things I can never remember the name for, I start losing my mind because I can’t remember all of the properties they’re talking about in the online videos/lectures/books. There’s 8 of them according to this class, but I can’t even tell you one of them. All I need is to pass this ONE class, and my brain can’t even comprehend any of it…which was the same in College Algebra, and why I failed it as well. Every other person I know, including my younger sister (who has now obtained a degree herself), has passed math with no problems whatsoever. I’m not exactly sure what’s wrong with me.

As an aside … I was useless at math….. still am … but am very good at what I need for work.

Once I realised what I wanted for my career … I had to go back to school.

Thank god for computers … they make me seem clever ☺

@Megachris%,

It may be your brain’s wiring. I had a college roommate who was an English major. He could not do math without a calculator or computer. Literally could not. My Achilles heel is languages, which he breezes through. I finally realized we are wired up differently.

The way he got through his math requirement was endless repetition — like I had to do in language courses — until the grooves were worn into his brain. Not to worry, he passed, got his degree, and went on to grad school. He is in a well paying career, all because he kept doing his math problems until his reluctant brain formed the necessary pathways.

BTW, it was temporary for both of us. It wore off as soon as we quit practicing and repeating.
