Math Problem Statement

log (y)=1.2 +0.1x if x is 2

Solution

To find the value of yy when x=2x = 2 in the equation:

log(y)=1.2+0.1x\log(y) = 1.2 + 0.1x

First, substitute x=2x = 2 into the equation:

log(y)=1.2+0.1(2)\log(y) = 1.2 + 0.1(2)

This simplifies to:

log(y)=1.2+0.2=1.4\log(y) = 1.2 + 0.2 = 1.4

Now, to solve for yy, we need to rewrite the logarithmic equation in exponential form:

y=101.4y = 10^{1.4}

Now, calculate 101.410^{1.4}:

y25.1189y \approx 25.1189

So, when x=2x = 2, the value of yy is approximately 25.12.
