Math Problem Statement

manipulate y^p=qe^(x+3) and express in Y=mX+c

Solution

We are given the equation:

yp=qe(x+3)y^p = qe^{(x + 3)}

Our goal is to manipulate it into the form Y=mX+cY = mX + c, which is the equation of a straight line.

Steps:

  1. Take the natural logarithm (ln) on both sides:

    Since e(x+3)e^{(x + 3)} has a base of ee, taking the natural log will help simplify the expression. So, apply ln\ln to both sides:

    ln(yp)=ln(qe(x+3))\ln(y^p) = \ln\left(qe^{(x + 3)}\right)

  2. Simplify both sides:

    On the left-hand side, using the logarithmic property ln(ab)=bln(a)\ln(a^b) = b\ln(a), we get:

    pln(y)=ln(q)+(x+3)p \ln(y) = \ln(q) + (x + 3)

  3. Rewrite to isolate terms:

    Expand the right side:

    pln(y)=ln(q)+x+3p \ln(y) = \ln(q) + x + 3

    Now, divide both sides by pp to isolate ln(y)\ln(y):

    ln(y)=ln(q)p+xp+3p\ln(y) = \frac{\ln(q)}{p} + \frac{x}{p} + \frac{3}{p}

  4. Rearrange into a straight-line form Y=mX+cY = mX + c:

    Compare with the standard straight-line equation Y=mX+cY = mX + c, where YY is the dependent variable, XX is the independent variable, mm is the slope, and cc is the y-intercept.

    Let:

    Y=ln(y),X=x,m=1p,andc=ln(q)p+3pY = \ln(y), \quad X = x, \quad m = \frac{1}{p}, \quad \text{and} \quad c = \frac{\ln(q)}{p} + \frac{3}{p}

Thus, the equation becomes:

ln(y)=1px+(ln(q)p+3p)\ln(y) = \frac{1}{p}x + \left(\frac{\ln(q)}{p} + \frac{3}{p}\right)

Which is in the form Y=mX+cY = mX + c with the following:

  • Slope m=1pm = \frac{1}{p}
  • Intercept c=ln(q)p+3pc = \frac{\ln(q)}{p} + \frac{3}{p}

Would you like further clarification on any of the steps or have additional questions? Here are a few related questions to explore further:

  1. How does the logarithmic transformation affect the slope of the line?
  2. What happens if pp is a negative value?
  3. Can this equation be used to solve for yy directly in terms of xx?
  4. How can we graph this equation?
  5. What is the significance of qq in the equation after the transformation?

Tip: Whenever dealing with exponential or logarithmic equations, consider using logarithms to linearize them for easier interpretation and graphing.
