Find the perimeter of the polygon. Round your answer to the nearest tenth.
lakkis [162]

Answer:

Option B.

Step-by-step explanation:

From the given figure it clear that the the vertices of the polynomial are Q(2,0), R(4,5), S(8,7), T(6,4) and U(10,3).

Distance formula:

d=\sqrt{(x-2-x_1)^2+(y_2-y_1)^2}

Using distance formula, we get

QR=\sqrt{\left(4-2\right)^2+\left(5-0\right)^2}=\sqrt{29}

RS=\sqrt{\left(8-4\right)^2+\left(7-5\right)^2}=2\sqrt{5}

ST=\sqrt{\left(6-8\right)^2+\left(4-7\right)^2}=\sqrt{13}

TU=\sqrt{\left(10-6\right)^2+\left(3-4\right)^2}=\sqrt{17}

QU=\sqrt{\left(10-2\right)^2+\left(3-0\right)^2}=\sqrt{73}

Now, the perimeter of the polynomial is

Perimeter=QR+RS+ST+TU+QU

Perimeter=\sqrt{29}+2\sqrt{5}+\sqrt{13}+\sqrt{17}+\sqrt{73}

Perimeter=26.12996

Perimeter\approx 26.1 units.

Therefore, the correct option is B.

Angel lives in Florida, which has a sales tax of 6%. He just bought some word-
slava [35]

Answer:

Option B

$65.4

Step-by-step explanation:

Imposing 6% tax on the full price would mean the final amount that should be paid will be equal to 106% of the full price, also expressed as 1.06 and this is equivalent to 1.06*90=$95.4.

However, since there's a coupon then the payment will be less the value of coupon. Therefore, final payable amount will be 95.4-30=$65.4

Anna71 [15]
After you have plotted the graph of the polynomial, the x-intercepts of the given polynomial will be:
(-3,0),(-1,0) and (4,0)
therefore the interval will be:
(-∞,-3)-below, (-3,-1)-above,(-1,4)-below,(4,∞)-above
The answer is ]
