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

Bailey writes the expression g^2 + 14g + 40 to represent the area of a planned school garden in square feet. What factors can be
Sedbober [7]

Answer:

(g + 4)(g + 10)

Step-by-step explanation:

Note that 10*4 = 40 (which is the constant in g^2 + 14g + 40) and that 10 + 4 = 14 (which is the coefficient of x in g^2 + 14g + 40).

Thus, g^2 + 14g + 40 factors into (g + 4)(g + 10) (second answer choice).

Are the two triangles below similar?
otez555 [7]
Yes they are similar. I believe one of them is smaller and upside. The size is different but the shape is the same!

An 18 in long rebar is driven into the ground until it touches an underground pipe. A backsight to a benchmark with an elevation
WARRIOR [948]

Answer:

398.71 ft

Step-by-step explanation:

Length of rebar = 18 inches  = 1.5 ft

Elevation  = 393.66 ft

Reading of backsight on Benchmark= 7.56 ft

Rod reading = 1.10 ft

<em>First step : determine height of Instrument been used</em>

= elevation + backsight on Benchmark

= 393.66 + 7.56 = 401.22 ft

<em>Elevation of top of rebar </em>

= 401.22  - 1.01  = 400.21 ft

Finally determine the elevation of the top of the pipe

= 400.21 - length of Bar

= 400.21 - 1.5 = 398.71 ft
