Find 9P9 and 9C9. Why do the answers differ?​
sveta [45]

We have been given two expressions 9P9\text{ and }9C9. We are asked to find the value of each.

To find 9P9, we will use permutations formula.

^nP_r=\frac{n!}{(n-r)!}, where

P = Number of permutations,

n = The total number of objects in the set,

r = Number of objects being chosen from the set.

9P9=\frac{9!}{(9-9)!}

9P9=\frac{9\cdot 8\cdot 7\cdot 6\cdot 5\cdot 4\cdot 3\cdot 2\cdot 1}{(0)!}

9P9=\frac{362880}{1}                   Using 0!=1

9P9=362880

To find 9C9, we will use combinations formula.

^nC_r=\frac{n!}{r!(n-r)!}, where

C = Number of combinations,

n = The total number of objects in the set,

r = Number of objects being chosen from the set.

9C9=\frac{9!}{9!(9-9)!}

9C9=\frac{9!}{9!(0)!}

9C9=\frac{9!}{9!\cdot 1}     Using 0!=1

Cancelling out 9!, we will get:

9C9=\frac{1}{1}

9C9=1

The answers differ because order. With permutations we care about the order of the elements, while with combinations we don't.

I'm need help a question and I'm confuse.
ipn [44]

Answer:

Step-by-step explanation:

Since angle ABD is 133 degrees and the sum of the angles in a triangle is 180 degrees, it means that

m∠ DAB + 133 + 22 = 180

m∠ DAB = 180 - 155 = 25 degrees

Also, ∆ ADC is an isosceles triangle because two of its sides are equal. It also means that the base angles are equal. Thus,

m∠ A = m∠ B

Therefore,

m∠ A + m∠ B + angle D = 180

m∠ A + m∠ B = 180 - 22 × 2

m∠ A + m∠ B = 180 - 44 = 136

m∠ A = m∠ B = 136/2 = 68 degrees

m∠ CAB + m∠ DAB = m∠ A

Therefore,

m∠ CAB = 68 - 25 = 43 degrees

Since ∆ ABC is isosceles, then

m∠ CAB = m∠ ACB

m∠ ACB = 43 degrees

m∠ ABC = 180 - (43 × 2) = 180 - 86

m∠ ABC = 94 degrees

m∠ BCD = 68 - m∠ ACB

m∠ BCD = 68 - 43 = 25 degrees
