-e-0.2t=1-1⋅22
Simplify the numerator.
Multiply -1 by 2.
-e-0.2t=1-22
Subtract 2 from 1.
-e-0.2t=-12
-e-0.2t=-12
Move the negative in front of the fraction.
-e-0.2t=-12
-e-0.2t=-12
Multiply each term in -e-0.2t=-12 by -1
Multiply each term in -e-0.2t=-12 by -1.
(-e-0.2t)⋅-1=-12⋅-1
Multiply (-e-0.2t)⋅-1.
Multiply -1 by -1.
1e-0.2t=-12⋅-1
Multiply e-0.2t by 1.
e-0.2t=-12⋅-1
e-0.2t=-12⋅-1
Multiply -12⋅-1.
Multiply -1 by -1.
e-0.2t=1(12)
Multiply 12 by 1.
e-0.2t=12
e-0.2t=12
e-0.2t=12
Take the natural logarithm of both sides of the equation to remove the variable from the exponent.
ln(e-0.2t)=ln(12)
Expand the left side.
Expand ln(e-0.2t) by moving -0.2t outside the logarithm.
-0.2tln(e)=ln(12)
The natural logarithm of e is 1.
-0.2t⋅1=ln(12)
Multiply -0.2 by 1.
-0.2t=ln(12)
-0.2t=ln(12)
Divide each term by -0.2 and simplify.
Divide each term in -0.2t=ln(12) by -0.2.
-0.2t-0.2=ln(12)-0.2
Cancel the common factor of -0.2.
t=ln(12)-0.2
Simplify ln(12)-0.2.
Move the negative in front of the fraction.
t=-ln(12)0.2
Divide 1 by 2.
t=-ln(0.5)0.2
Rewrite.
t=–0.693147180.2
Divide -0.69314718 by 0.2.
t=–3.4657359
Multiply -1 by -3.4657359.
t=3.4657359
t=3.4657359
t=3.4657359
Solve for t 5/10=(10(1-e^(-0.2t)))/10
