Take "log" of the equation and plot the tabulated values.I need to find the constants a and b of the function V=aP^b
I have a table of values of P and V but I am not sure how to proceed
Thanks in advance
Are you not familiar with logarithms? If not, then what method has your class covered for this sort of exercise? Are you supposed to do a regression in your graphing calculator? If so, then where are you getting stuck?Please could you explain further?
I have included the table of values if that helps
Thanks
P 126 178 263 398 525 724
V 1.86 2.34 2.75 3.63 4.17 4.79
\(\displaystyle \text {Let } v = log(V) \text { and } p = log(P) \text { and } c = log(a).\)The full question is the fore P newtons required to keep an object moving at a speed V meters per second was recorded.
P 126 178 263 398 525 724
V 1.86 2.34 2.75 3.63 4.17 4.79
The law connecting P and is of the form V = aP^b where a and b are constants. Use appropriate graphical and algebraic techniques to find the values of a and b.
I am familiar with logs but I am not sure how to use them to find a and b
Thanks
