expand 90(1-e^{-t/2})

expand

90 (1 - e^{- \frac{t}{2}})

90 - 90 e^{- \frac{t}{2}}

Solution steps

90 (1 - e^{- \frac{t}{2}})

Apply the distributive law:

a (b - c) = ab - a c

a = 90, b = 1, c = e^{- \frac{t}{2}}

= 90 \cdot 1 - 90 e^{- \frac{t}{2}}

Multiply the numbers:

90 \cdot 1 = 90

= 90 - 90 e^{- \frac{t}{2}}

(3 e - 9) \cdot 8

\frac{2}{( x + a ) ( x + b )}

\frac{( x - 2 )}{( x - 1 ) ^{2}}

- \frac{3}{( s ^{2} - 4 s ) ( s + 1 )}

5 \cdot 89
