I know that were doing problems were there is a soultion given which is equal to X^? times a constant ...
y = k x^?
So this is problem I have to decide given a probelm x relationship to y (for example iverse square cube and so forth) this unkown variable is denoted witha (?)
So given two points (Q,W) (E,R) how do I determiine the relationsip of x to y... and solve for the (?)
I guess so far in my book the constant is raised to the first power is there any way I could find out if the constant is not raised to first power or not???
Once I come up with the formula I know how to do the rest I just don't know how to obtain the formula and solve for the (?) once you do it's just plug and chug...
so please show me how to solve for (?) given two points
woops sorry edited the wrong box there we go
I still don't know how to solve these types of problems
Assistance needed.
(Perhaps if you put ONLY the subject in the School Subject box and put ONLY your first name in the First Name box and reposted your question, someone would be inclined to help.)
need help go to tutor vista just put those together
To solve for the unknown exponent (?) in the equation y = kx^?, you need to use the two given points (Q,W) and (E,R) to form a system of equations.
Let's say the first point (Q,W) satisfies the equation:
W = k(Q^?)
Similarly, the second point (E,R) satisfies the equation:
R = k(E^?)
To find the exponent (?), you need to eliminate the constant k from these equations. To do that, you can divide the second equation by the first equation:
R/W = (k(E^?))/(k(Q^?))
R/W = (E^?)/(Q^?)
Now, you can take the logarithm of both sides of this equation to remove the exponent:
log(R/W) = ?[log(E) - log(Q)]
Simplifying further, you get:
? = (log(R/W))/(log(E) - log(Q))
This formula allows you to solve for the exponent (?) given the two points (Q,W) and (E,R).
Remember, this method assumes that the relationship between x and y can be represented by the equation y = kx^?. If the relationship is more complex or nonlinear, this approach may not be applicable.
