Answer:
4.708 feet
Step-by-step explanation:
Given that: The sector area A=28.25 ft2
The radius r = 12 feet
....attached work below
Now the length of steel (Arc length ) = 2πr/2π × θ
The length of steel (Arc length ) = r × θ
The length of steel (Arc length ) = 12 × 0.39236
The length of steel (Arc length ) = 4.708 feet

Answer:
$5466.36
Step-by-step explanation:
This question is pretty cut and dry
just plug in the numbers
We have that
f(x) = (x – 5)³(x + 2)²
we know that
<span>the roots can touch or cross the x axis
</span>The way you can tell if the graph is going to cross the x-axis or just touch the x-axis is by looking at the power of the factor.
(x - 5)³ has a power of 3 which is an ODD number. An ODD power means that the graph will cross through the x-axis.
(x + 2)² has a power of 2 which is an EVEN number. An EVEN power means that the graph will touch the x-axis.
therefore
the answer is
<span>the graph of f(x) touch the x axis for the root x=-2
</span>
see the attached figure
