The diagram shows the curve y=(1/2x-2)^6+5. Find the area of the shaded region.
Zepler [3.9K]
So the line that is the limit is where the equation crosses the y axis or where x=0

so
y=(1/2(0)-2)^2+5
y=(-2)^2+5
y=4+5
y=9
at y=9

the upper bound is y=9

alrighty

we will do
let's call the curve that is 6th degree f(x)
and the y=9, g(x)

f(x)=(1/2x-2)^6+5
g(x)=9

find where they intersect

9=(1/2x-2)^6+5
4=(1/2x-2)^6
fancy math
x=8

so the area under the curve will be
\int\limits^8_0 {g(x)-f(x)} \, dx because g(x) is above f(x)
so

\int\limits^8_0 {g(x)-f(x)} \, dx= \int\limits^8_0 {9-((\frac{1}{2}x-2)^6+5)} \, dx=
using our calculator because I can't figure out what \int\limits (\frac{1}{2}x-2)^6} \, dx is
\int\limits^8_0 {9-((\frac{1}{2}x-2)^6+5)} \, dx= \frac{64}{3} or about 21.33333333

4/5x = 32  

0.8x = 32

What is -27 equals 4.5 s
iVinArrow [24]
If the sine if 4/5, then the side opposite is 4 and the hypotenuse is 5. This means it's the 3, 4, 5 right triangle (or similar, such as 6, 8, 10). 
cos = 3/5
tan = 4/3
cot = 3/4
sec = 5/3
csc = 5/4
