integral from 0 to 0.6 of 400x

\int_{0}^{0.6} 400 x d x

72

Solution steps

\int_{0}^{0.6} 400 x d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 400 \cdot \int_{0}^{0.6} x d x

Apply the Power Rule

= 400 [\frac{x ^{2}}{2}]_{0}^{0.6}

Simplify

= 400 [0.5 x^{2}]_{0}^{0.6}

Compute the boundaries:

0.18

= 400 \cdot 0.18

Simplify

= 72
