Answer:
5 hours.
Step-by-step explanation:
2^9=512
2^10=1024
10*30 minutes=5 hours
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

because g(x) is above f(x)
so

using our calculator because I can't figure out what

is

or about 21.33333333
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).
Yes they are similar. I believe one of them is smaller and upside. The size is different but the shape is the same!
Hope this helped :)
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
