Answer:

Step-by-step explanation:

From the picture attached,

Two circles having centers A and B intersect each other at C and D.

We do a construction by joining points A and B to form a line segments AB.

From circle A,

AC ≅ AB ≅ AD [Radii of the circle A]

From circle B,

BC ≅ AB ≅ BD [Radii of the circle B]

Therefore, AC ≅ AD ≅ BC ≅ BD ≅ AB.

These segments of the quadrilateral are equal in measure.

Need help with this problem explain pls
Usimov [2.4K]
All sides of an equilateral triangle are equal, so all three sides are 9 cm.
To find h, use the pythagorean theorem. This requires use of only one right triangle, where we use b as our h.

a^2+b^2=c^2
(4.5)^2+b^2=(9)^2
(20.25)+b^2=(81)
b^2=(81/20.25) or 4
square root both sides
b=2

A 5-digit combination lock with digits 0-9 can be opened only if a correct combination of digits is chosen. Find the probability
sammy [17]

The total number of combinations without restrictions is

10 * 10 * 10 * 10 * 10 = 100000

Problem A

10 * 9 * 8 * 7 * 6  = 30240

the number of ways the combination can be set up with no repetition.

The probability of such an event is P = 30240 / 100000 = 0.3024

Problem B

The number of ways that can be done with repetition and no zeros is

9 * 9 * 9 * 9 * 9 = 59049

The probability of such an event is

P = 59049 / 100000 = 0.59049
