What does a straight line graph indicate?
A straight line graph can also be used where exponentials are involved.Take the equation Q = AP^x , say. Eq1The data concerning Q and P is available, you know that there is not a linear relationship between Q and P.The problem now is to find a value for A and x.If logs. of both sides of Eq1 are taken ,the problem is reduced from being an exponential to a linear one, as.Q = AP^x. becomesln Q. = ln A + x ln P call this line LDraw this line 1. Where this line cuts the y axis is the value of ln A ,call it nso if ln A = n then A = e^n . Eq22 x above happens to be the slope of line L ,so calculate ,m the slope . Just measure (rise)/(run).= xSlope = x. Eq3Sub. Eq2 and Eq3 into Eq1.The exponential problem is solved using a log .linear technique
Help with Chemistry Question? Integrated Rate Law?
The integrated rate laws for zero-, first-, and second-order reaction may be arranged such that they resemble the equation for a straight line, y=mx+b. Please help me out! A. The reactant concentration in a zero-order reaction was 0.100 M after 190s and 4.00×10−2 M after 305s . What is the rate constant for this reaction? B. What was the initial reactant concentration for the reaction described in Part A? C. The reactant concentration in a first-order reaction was 7.80×10−2 M after 40.0s and 7.50×10−3 M after 100s . What is the rate constant for this reaction? D. The reactant concentration in a second-order reaction was 0.810 M after 265s and 8.50×10−2 M after 710s . What is the rate constant for this reaction?
How do i work out heart rate from a pressue/time graph?
Heart rate in beats per minute = 60 divided by time in seconds between peak or valley of repetitive pressure pulse.
What is price of 1 minute motion graphics video in USD?
Hi.Unfortunately, the correct answer to your question is: “It depends!”What level of detail and quality are you after?Do you want everything to be created from scratch or are you ok with templates?Do you have a script already?Will you do your own voice-over?I would not go lower than $300 USD for a one-minute video.And that video would be very basic and simple.Cheaper videos are often not synchronized and are using templates.To get better quality you have to pay at least $500 USD.With $1000+ you will get results that are much more professional.The characters are looking great and the music and sound effects are perfectly synchronized.Creating high-quality videos takes time and a lot of work.I am still looking for customers to expand my portfolio.So, if you are interested, you can get a professional video for an unbeatable price.>>>>> My website <<<<

A bus accelerates from rest for time t1 at a constant rate of alpha and then retards its acceleration at the constant rate beta for time t2, and comes back to rest. What is 't1/t2'?
THE question divided in two part,….in first part,initial velocity u=0, acceleration = alpha(a), time= t1first law of motion- v1=u+a*t1so v1 = a*t1——————(1)2. in second part, initial velocity is = final velocity of first part i.e. v1u=v1, deacceleration = beta(B) , time = t2, final velocity v2=0first law of motion- v2=v1-B*t2 or 0=v1-B*t2so v1=B*t2—————(2)divide (1)and (2)a*t1/B*t2=1t1/t2 = B/a so t1/t2 is the ratio of deacceleration over acceleration.
How do I present the term structure of interest rates in a single graph?
The level of rates TODAY is shown by the traditional yield curve, as suggested by Mr. Ranner. Years on the X-axis and rates on the Y-axis.But there is an interesting addition which really shows the core concept of “structure,” and that’s the implied forward rate. It’s true that the yield curve usually slopes upward, but what does that really mean?One view is that there are always people who invest as if they will need the money back soon, so they only buy one year bonds. And always some people who want the most interest, no matter how long they have to leave the money. That’s the “preferred habitat” view of investors.There is a broader view that says besides such preferences, there are lots more “rational expectation” investors who will go back and forth wherever there is the best deal, considering not just current rates but FUTURE rates. These investors consider all the alternatives.For example, is it better to invest for one year and then reinvest again for another year at the new one year rate? Or is it better to invest for two years, today? Well we know the one year and two year rate today, from the current yield curve. So what does that imply about the one-year rate, NEXT year?Let’s say we that with today’s yield curve we can invest at 1% for one year, or 2% for two years. What does that about the one-year rate, NEXT year? IF the two pathways are to be equal, then let’s solve: (1.01)*(1 +x) = (1.02)*(1.02).Turns out X = 3.0099. Rather intuitive. Getting a 1 and a 3 is (about the same as getting two 2’s. That means rational investors expect the one year rate to rise next year to 3,0099 next year.We can do that all along the curve and say “Based on THIS year’s yield curve, here is what investors EXPECT the full yield curve to be NEXT year.”That reveals a lot about the inner structure of the yield curve. Here’s an example: Implied forward rates puzzle
Microsoft Excel: I need to sort sales data into categories high >50, Medium >= 35 and Low <30. How would I compose the IF function to do so?
There are two ways to approach this problem: with an IF statement and with a VLOOKUP.IF statement:You'll have to use a nested IF statement. Your range is missing numbers, so I'll assumeHigh: 50+Medium: 30-49Low: <30With this info, the if statement will look like: IF(A1>49,"High",IF(A1>29,"Medium","Low"))It's easy to imagine how this process goes, but let me know if you want me to explain.VLOOKUP:First step is to create a 2x3 table, in descending order, with upper limit values on the left (except for the first record) and categories on the right.This would look like:The next step is the formula which would be:VLOOKUP(D1,$A$1:$B$3,2,1)D1 refers to the cell with the value to be categorized.A1:B3 is the table range thats shown above, and $ signs are to keep the range static, instead of changing when you drag down/copy+paste the formula to other cells. 2 refers to which column number in the table to return.1 is a Boolean operator, which if changed to 0, would only return the exact value (only 0,30,and 50 would not return an error). 1 returns an approximate value, in this case works like 'greater than or equal to' due to the descending order of the table.
How do you calculate instantaneous rate in excel?
If you have a column of data with the cumulative distribution in it, you can aproximate the answer by using the formula [y(n) - y(n-1)]/[x(n) - x(n-1)] in a column adjacent to the ones with the data.
