Question

evaluate the given integral
5.4e^(-4x+5)dx

Answer 1

factor out 5.4, so you have 5.4 (integral) e^(-4x+5)dx, then use substitution

Answer 2

So I know that u would be -4x+5 and du would be -4 dx but I dont know what to do after that

Answer 3

dx = -1/4du

-1/4 * 5.4 (integral) e^u

take the integral of e^u

Answer 4

right so then plug in for u and du

dx = du/-4

\[-\frac{5.4}{4} \int\limits e^{u} du\]

Answer 5

Ok thanks!
