integral of 0.8x

Solution

\int 0.8 x d x

Solution

0.4 x^{2} + C

Solution steps

\int 0.8 x d x

Take the constant out:

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

= 0.8 \cdot \int x d x

Apply the Power Rule

: \frac{x ^{2}}{2}

= 0.8 \cdot \frac{x ^{2}}{2}

Simplify

0.8 \cdot \frac{x ^{2}}{2} : 0.4 x^{2}

= 0.4 x^{2}

Add a constant to the solution

= 0.4 x^{2} + C
