Answer:
See proof below
Step-by-step explanation:
We have to verify that if we substitute 
in the equation 
the equality is true.
Let's substitute first in the right hand side:
Now we use the distributive laws. Also, note that 
(this also works when the power is n-2).
then the sequence solves the recurrence relation.
Answer:
25.64 in^2
Explanation:
<span><span>60360</span>⋅π<span>r2</span></span>, where <span>r=7</span>
<span>=<span>16</span>⋅3.14⋅<span>72</span>=<span>16</span>⋅3.14⋅49=25.64</span> in^2
<span>B. The longer leg is times as long as the shorter leg.
</span> <span>C. the hypotenuse is twice as long as the shorter leg.</span>
The area of a circle is given by A=Pi*r^2, and its perimeter, P=2*Pi*r.
To get the radius r, you must divide 452.2 by Pi, and then calculate the square root of this quotient.
To get the circumference or perimeter, use the radius in the formula P=2*Pi*r.
Finally, round the number you get to the nearest tenth.
