Question

Find the Area enclosed by the curve "y=sqrt(5x+4)", x-axis, y-axis, and the line x=1

Answer 1

the area is integration, a picture is nice but immaterial at the moment

Answer 2

\[A=\int_{a}^{b}f(x)~dx\]

Answer 3

I got as far as \[\int\limits_{0}^{1} \left( \sqrt{5x+4} \right)dx\]

Answer 4

convert the rt to a power

Answer 5

and, if you cant see it clearly, try a u substitution

Answer 6

\[\int\limits_{0}^{1}\left( 5x+4 \right)^{\frac{ 1 }{ 2}}dx\]

Answer 7

if we let 5x+4 = u

what does dx become?

Answer 8

i really have no idea

Answer 9

take a derivative with respect to x ... ive got real life issues pressing so ill be away for a few hours at best
