Chapter 16, Problem 16.1EAA

To determine

The value of $t$ .

Explanation of Solution

Given Information:

$A=10e^{2t}$….(1)

$A=100$

Calculation:

Considering the given values, equation (1) takes the form-

$100=10e^{2t}$

Or $10=e^{2t}$

Taking natural logarithm on both sides, we get

$\ln 10=\ln e^{2t}$

Using the calculator, we find

$2.3025=2t$

Therefore,

$t=2.3025/2$

$t=1.151$

Conclusion:

Correct answer is c) 1.151
