Can you explain how you got this answer? I'm super confused. We had done one in class that was easier because it was worded slightly different and I could just do y2-y1 over x2-x1. 

ex. f(2)=5 and f(2.005)=5.012. well you would just subtract 5.012-5 over 2.005-2 which gives you 2.4.

The problem I posted I was stuck staring at versus the one above. 

thanks. I am getting confused on the second one because in the problem you did, you subtracted the 1-9. In the second problem I tried doing that same thing. It was incorrect. 9-(1-x)^2= (8-x)^2 =x^2+16x+64 that was incorrect. I guess Im wondering where I went wrong?

we are trying to find h(x) though. In your answer you gave h(x) We don't know that. The final answer you gave was the problem we started with sqrt of x^9+9

edit- Okay I see now how you got hx I was confused at first. Thanks.

Suppose g is a linear function such that g(1.2) = 3.3 and g(-3) = 7.2. Find the equation for g. (Use x for the variable. Round equation parameters to two decimal places.)

On this question, I did the y2-y1/x2-x1 and got -2.17 rounded. that wasnt correct. It is almost like the question you helped me with but a little different. Care to help me with this one? 

I appreciate you! 

So I had the answer all along but I got it wrong because I didnt put a negative. But it was as simple as I thought. -.45       5/11 

I answered -.04 but that wasnt correct. Remember the slope is downward.

thanks but it doesnt answer part c. 

the answer was .49. 1.06^1/12=1.004867551-1=.0048675506x100=.4867550565 rounds to .49.  thanks anyway!

I am not 100% as I am learning about this too so here I go. a=1-r is the decay formula a=1-.1=.9 .9^12=.282429=.28 rounded to two decimal places. I raised the.9 to the 12th because there are 12 months in 1 year. Do you have multiple attempts? 

a. 10yrs=1 decade so, 1.34 to the 1/10 gives you 1.03 {1.34^1/10}=1.03 YEARLY GROWTH FACTOR

 3.93 x1.03^y FORMULA

b. 1.34^10=18.67 CENTURY GROWTH FACTOR=18.67

so 3.93 x 18.67^c FORMULA You raise the 1.34 by 10 because there are 10 decades in 1 century.  

I typed about that in the problem when I typed ps. But thanks for posting anyway. 

That would be correct because the answer was .34. Where were you sooner?! lol Im kidding, thank you though!!

Awesome, thank you! That is how we did it in class but I get confused when it asks for years and months. 

They are both incorrect, the first one was .34 and the second one is incorrect. I have one more attempt. 

Thanks so much! Also how did you know to multiply by 100? I see that you suibtracted 1. Is that the decay formula a=1-r?

I haven't tried because I don't think it is correct and this is my last attempt. 

Is that one about the 25% question? Where you answered 0.03?

Actually i dont think that would be correct. Now that I am looking at how you answered.
