<span>The (x,y) point of the vertex is usually labelled as:
Vertex = (h, k)
h = -b / 2a
h = --64 / 2*8
h = 64 / 16
</span><span>h = 4

</span>
<span>To get “k”, input the “h” value into the equation.
<span>k = 8*(4^2) -64*4
</span> <span>k = 8*(4^2) -64*4
</span><span>k = 128 -256
</span><span>k = -128
</span></span><span>Vertex = (4, -128)

Find the perimeter of this figure to the nearest tenth. Use 3.1 to approximate

marusya05 [52]

Since the diameter and height of both shapes are the same, we know that the equation to solve for the semi circle is:

πr = 3.1*8 = 24.8

16 + 20 = 36

36 + 24.8 = 60.8

The perimeter of the shape is 60.8 ft

Yuliya22 [10]

Answer: The required proportion is $\dfrac{172}{523}$ in fraction and $0.329$ in decimals.

Step-by-step explanation:

Since we have given that

Number of suspected criminals is drawn = 523

Number of criminals were captured = 172

We need to find the proportion of people who were caught after being on the 10 Most wanted list.

So, Proportion of people who were caught is given by

$\dfrac{172}{523}\\\\=0.3288\\\\\approx 0.329$

Hence, the required proportion is $\dfrac{172}{523}$ in fraction and $0.329$ in decimals.
