Fig., QR is a common tangent to the given circles,
Citrus2011 [14]

Answer:

QR = 7.6 cm

Step-by-step explanation:

By theorem of tangents drawn from an external point to a circle,

"Tangents drawn from an external point to a circle are equal in measure"

By this property,

PQ = PT = 3.8 cm

And PR = PT = 3.8 cm

Since, QR = PQ + PR [By segment addition postulate]

QR = 3.8 + 3.8

QR = 7.6 cm

40 Points Please Help I'm not sure if they are correct.

Replace the x and y values in the given equation.

1. d = √((6-0)^2 + (8-0)^2

= √(6^2 + 8^2)

= √(36 + 64)

= √100

= 10

2. d = √((3-(-3))^2 + (5-2)^2

=√((3+3)^2 + 3^2)

=√(6^2 + 3^2)

= √(36 + 9)

= √45

=3√5 ( exact ) or as a decimal 6.7082 (round as needed)

3.  d = √((4-(-1))^2 + (-5-(-1))^2

= √((4+1)^2 + (-5+1)^2)

= √(5^2 + -4^2)

=√(25 + 16)

= √41 (exact) or as a decimal 6.4031 (round as needed)

Three coins are dropped on a table.
Dominik [7]

Answer:

(a) S = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}

(b) \frac{1}{8}

(c) \binom{3}{2} (\frac{1}{2})^3 = \frac{3}{8}

(d) (\frac{1}{2})^3 + \binom{3}{1} (\frac{1}{2})^3 = \frac{1}{8} + \frac{3}{8} = \frac{1}{2}

(e) 1 - \frac{1}{2} = \frac{1}{2}

(f) Yes, because P(A \cap B) = 0. Therefore P(A \cup B) = P(A) + P(B) = \frac{3}{8} + \frac{1}{2} = \frac{7}{8}

(g) No, because P(A \cap C) = \frac{3}{8}. Therefore P(A \cup C) = P(A) + P(C) - P(A \cap C) = \frac{3}{8} + \frac{1}{2} - \frac{3}{8} = \frac{1}{2}
