Answer:
Perimeter = 36 units
Step-by-step explanation:
The figure given has been labelled with letters for easy reference.
Recall: when two tangents segments meet at a point outside the circle, the two segments that are tangent to the circle are congruent to each.
Perimeter = a + b + c + d + e + f
e = 4 (given)
e = f = 4 (tangents drawn from an external point)
b = 10 - f
Substitute
b = 10 - 4
b = 6
b = a = 6 (tangents drawn from an external point)
c = 8 (given)
c = d = 8 (tangents drawn from an external point)
Perimeter = 6 + 6 + 8 + 8 + 4 + 4
Perimeter = 36 units
The statement that correctly describes the proportion of arm spans that are longer than 170 cm in the stem plot is C. The The proportion of arm spans that are longer than 170 cm is about the same for Class A and Class B.
<h3>How to illustrate the information?</h3>
It should be noted that from the information given, the variability of the arm span shows that they have about same variability.
Therefore, the statement that correctly describes the proportion of arm spans that are longer than 170 cm in the stem plot is C. The The proportion of arm spans that are longer than 170 cm is about the same for Class A and Class B.

Answer:
(x-8)^2+(y+8)^2=7
Step-by-step explanation:
The equation of a circle is (x-h)^2+(y-k)^2=r^2
Substitute h, k, and r for 8, -8, and √7, respectively.
(x-(8))^2+(y-(-8))^2=(√7)^2
The two negatives in y - (-8) causes it to be a +8. Squaring √7 will make it 7.
