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

Arada [10]
Laura has a total of 13 books. To pick 3 out of this 13 books is expressed as 13C3 which is equal to 286. Now to pick a science and 2 mathematics books may be expressed as,
                                       (4C2) x (6C1) = 36
The probability is the quotient when 36 is dived by 286. The answer is 18/143 which is approximately equal to 0.126.

Which set of angles are alternate interior angles
hammer [34]

Hello!

E) 3 and 6

interior angles are the angles on the inside of the parallel angles. In this case, 3, 4,  5, and 6 are interior angles.

<u>alternate</u> exterior angles are 2 interior angles on opposite sides of the line passing through the middle.

in this case, the alternate exterior angles are: 3 and 6 / 5 and 4

choosing from your answer choices, you'll see that the only option that matches either of the 2 alternate interior angles I listed is: E) 3 and 6

I hope this helps, and have a nice day!
