$t = - 18 + 42 e^{- 0.025 \cdot 18}$

Step 1

Multiply $- 0.025$ by $18$ .

$t = - 18 + 42 e^{- 0.45}$

Step 2

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$t = - 18 + 42 \frac{1}{e^{0.45}}$

Step 3

Combine $42$ and $\frac{1}{e^{0.45}}$ .

$t = - 18 + \frac{42}{e^{0.45}}$

Step 4

The result can be shown in multiple forms.

Exact Form:

$t = - 18 + \frac{42}{e^{0.45}}$

Decimal Form:

$t = 8.78038236 \dots$
