Which regular polygon has a minimum rotation of 45 degrees to carry the polygon onto itself?
lubasha [3.4K]

Answer:

Hence, a regular polygon that has a minimum rotation of 45 degrees to carry the polygon onto itself is:

A. octagon.

Step-by-step explanation:

We know that the for a regular polygon with 'n' sides the minimum rotation that can carry the polygon onto itself is:

\dfrac{360\degree}{n}

Here we are given the minimum angle of  rotation such that polygon is transformed to itself as 45 degree.

i.e. we have:

\dfrac{360}{n}=45\\\\n=\dfrac{360}{45}\\\\n=8

Hence, the number of sides of a polygon are 8.

Hence, the polygon is:

A. octagon.

( Since a polygon with 8 sides is called a octagon)

If the purchase price for a house is $218,500, what is the monthly payment if you put 3.5% down for a 30 year loan with a fixed
artcher [175]
218,500 - (3.5% down payment) =
210,852.50
30 years = 360 months
rate 6.5%
Use the loan payment formula (REALLY complex - see attached).
rate = 6.5/1,200 = <span> <span> <span> 0.005416667 </span> </span> </span>

monthly payment = (rate + [rate / (((1 + rate)^months) -1)] * principal
monthly payment = (<span>0.005416667 + [</span><span>0.005416667 / (((1</span><span>.005416667)^360)-1)] * principal
</span>monthly payment = (0.005416667 + [0.005416667 / (((1.005416667)^360)-1)] * principal
monthly payment = <span>0.005416667 + [</span><span>(0.005416667 / 6.9917988084 -1)] * </span> <span> <span> <span> 210,852.50 </span> </span> </span>
monthly payment = 0.005416667 + [(0.005416667 / 5.9917988084)] *  <span> <span> 210,852.50 </span> </span>
monthly payment = 0.005416667 + [(0.005416667 / 5.9917988084)] *  <span> 210,852.50 </span>
<span>monthly payment = (0.005416667 + 0.0009040135) * </span><span>210,852.50
</span>monthly payment = <span> <span> <span> 0.0063206805 </span> </span> </span> * <span>210,852.50
</span>monthly payment = <span> <span> <span> 1,332.73</span></span></span>
